Fleet Patch Audit — 2026-06-19

Read-only audit snapshot as of 2026-06-19. Nothing has been applied — this is a planning document to build the patch plan from.

Topology note: the old Contabo VPS has been rebuilt as edge1 (mail-only); edge2 is now the front door for everything else. edge1 is excluded from this audit (mid-rebuild/maintenance). Headscale: edge2 CT107 is the main fleet tailnet (34 nodes, vpn.echo6.co, self-hosted Headscale 0.28.0); utility CT106 is a separate IdahoMesh sub-tailnet (vpn.idahomesh.com, 3 nodes, low-risk). No services route through old-Contabo. Mailcow CT108: destroyed 2026-06-20 (pct destroy 108 --purge); backup preserved durably on pi-nas (…/contabo-prewipe-2026-06/mailcow/, sha256-verified); live mail on edge1 (MX/A for mail.echo6.co → 5.189.158.149).

Prioritized Backlog

Tier 1 — Security-Urgent Guest OS

These containers have the highest raw security-update counts and have not been patched recently (or never). Address before any platform work.

Host Guest Upgradable / Security Notes
utility CT119 mesh-territory 179 / 91 sec Never patched
utility CT108 meshai 109 / 79 —

Tier 2 — App / Container Updates

Updates where the application or its Docker images have drifted from current upstream, ordered roughly by operational risk.

Scope Guest Item Notes

Non-Update Flags

Issues noted that are not package/image updates but warrant attention.

Host / Guest Flag Detail
data Disk 92% full ~73 GB / 938 GB free; address before patching
utility CT118 archivist rpcbind on 0.0.0.0:111 No Tailscale client or firewall on this CT; exposed port

edge2 CT106 matrix / CT107 headscale No Tailscale client Ingress via Caddy; verify internal routing before patching

Application Currency (2026-06-19)

Running application version vs latest stable upstream, per app — the "is everything up to date?" view (distinct from OS-package/image-drift above). Read-only. Caveat: version deltas were measured directly from the running apps and are reliable; the specific CVE/advisory IDs below were surfaced by the audit agents and are post-knowledge-cutoff — verify against primary advisories before acting on them. GitHub's anonymous API rate-limited a few "latest" lookups (noted inline).

Security-relevant — prioritize

Operational / host-level (not a simple app bump)

Item Where Finding
Mailcow edge2 CT108 ✅ DECOMMISSIONED 2026-06-20 — destroyed (pct destroy 108 --purge); backup on pi-nas, live mail on edge1.
Host kernel edge2 host Agent flagged DirtyFrag (CVE-2026-43284/-43500) + copy.fail (CVE-2026-31431, claimed CISA KEV) as host-kernel LPE. Tension: the host audit showed edge2 fully patched (0 upgradable) on its repo — verify whether these need a kernel newer than the no-subscription repo provides.

Current / already past the fix (no action)

Vaultwarden 1.36.0 (edge2 CT102 — has the SSO-takeover/org-access CVE fixes) · PDM 1.1.4 (edge2 CT100 — past the RCE PSA) · WordPress 7.0 core + all plugins/themes (edge2 CT101) · Synapse 1.155.0 / Element / MAS (edge2 CT106 — current, only minor :latest digest drift) · obsidian-remote v1.12.7 (cortex) · PostgreSQL 16.14 (recon-vm).

Internal echo6 apps (no upstream to track)

central-, meshai, archivist, meshwars, recon / recon-watchdog, navi- — running; version = current git head.

Proposed Patch Approach (NOT executed — for planning)

Lowest-risk changes first; everything reboot-bearing deferred to scheduled windows.

Principles

  • Security-pocket apt only in the first pass (openssl, openssh, gnutls, krb5, libc6, samba, nghttp2, etc.). No PVE 9.2 / QEMU / LXC / kernel, no Docker image pulls, no OMV/NVIDIA, no reboots.
  • Protected hosts (cortex, toc) never go in a bulk pass — handled individually in their own window. Note: toc hosts cortex (VM150), so a toc reboot drops cortex — the two must be coordinated together.
  • edge1 (mail) excluded while it's mid-rebuild.
  • needrestart will bounce affected daemons after glibc/openssl upgrades — seconds of blip per guest, no data risk.

Phased plan

Phase Scope Reboot? Notes
1 — Guest/VM security apt utility CT100,101,102,103,104,106,107,108,109,112,118,119 · cloud CT120,121 · media VM105,CT110,CT111 · data VM1130 · edge2 CT100–107 No Lowest blast radius. Worst-first: CT119, CT108, immich/nextcloud guest-OS, peertube.
2 — Hypervisor host OS security data, utility, cloud, media host OSes (not toc) No One node at a time; restarts hypervisor-side daemons (smbd etc.). edge2 host already patched.
3 — App / container updates (Tier 2) per-app, native updater each Per-app Substantially complete 2026-06-21 — all security-critical apps done; low-urgency batch + cortex AI stack remain. See Phase 2 Execution Log and "special handling" below.
4 — Reboot windows (Tier 3) PVE 9.2 + QEMU 11 + LXC 7 + kernel on the 5 PVE-9 nodes; pi-nas kernel + OMV; cortex NVIDIA/DKMS Yes Schedule deliberately; toc+cortex coordinated.
Cross-cutting Tailscale 1.94→1.98 fleet-wide No Can ride along Phase 1/2.

Special handling — do NOT bulk-patch these; use the native updater

  • mailcow (edge2 CT108) → ✅ decommissioned 2026-06-20, no action
  • nextcloud AIO (cloud CT121) → update mastercontainer, then in-UI update button (port 8080)
  • immich (cloud CT120) → docker compose pull && up -d from its compose dir
  • authentik (edge2 CT105) → sequential version upgrades with migrations; 2025.12.4 → 2026.2.0 cannot skip releases
  • pi-nas OMV → OMV's own update path, not raw apt
  • cortex / toc → manual, protected, own window

Open Decisions

Resolved (2026-06-19/20)

  1. RabbitMQ 3.12→4.x — ACCEPTED as a decoupled sub-task (Erlang ≥26 → 3.13.x → enable feature-flags → 4.x); the OpenTAKServer bump does NOT cover it. In scope for this campaign.
  2. Break-glass — VALIDATED: all 7 LAN SSH paths work independent of the tailnet; every PVE node (incl. edge2) has local pam/pve realms; Authentik akadmin, Forgejo matt, Nextcloud admin local logins confirmed. ⚠️ One gap → PDM (edge2 CT100) has only openid:authentik in domains.cfg; confirm root@pam login at https://100.64.0.28:8443 (or add a pam: stanza) before the Authentik upgrade.
  3. Phase scope — ALL PHASES; no-reboot work (Phase 1–2) first, platform/reboot (Phase 3) scheduled separately.
  4. Daemon-restart tolerance — DOWNTIME ACCEPTED; needrestart blips OK on the stateful guests (still take logical DB dumps for safety, but no holding restarts for availability).
  5. edge2 host kernel (DirtyFrag/copy.fail) — NO ACTION / NO REBOOT: running 6.8.12-30-pve, the newest its repos offer; no update available, no reboot-required flag. Not actionable without a repo/branch change. edge2 needs no Phase 3 reboot.
  6. CVE verification — NOT GATING: being behind on versions is sufficient justification; post-cutoff CVE IDs are not chased or relied on for ordering.
  7. Maintenance windows — NO CONSTRAINT (single user); disruptive steps may run anytime, no scheduling/announcement needed.
  8. Nominatim 4→5 — DEFERRED / OUT OF SCOPE: spun off to nominatim-v5-reimport as its own project.
  9. Headscale location — RESOLVED: fleet control plane = edge2 CT107 (vpn.echo6.co, 34 nodes — high-risk); IdahoMesh sub-tailnet = utility CT106 (vpn.idahomesh.com, 3 nodes — low-risk). No Contabo routing.
  10. mailcow CT108 — RESOLVED: superseded by edge1; safe to decommission (pending backup-off-CT verify below).
  11. Phase 2 host-OS sequencing — RESOLVED: folded into Phase 3 reboot window.
  12. In-scope app campaign — Forgejo 14→15, Matrix/Synapse, Authentik chain, RabbitMQ, media stack, immich, nextcloud, headscale, cortex AI. (Nominatim excluded per #8.)

Pre-flight gates — status (2026-06-20)

  • PDM break-glass — ✅ DONE: local admin@pam (Administrator) created on PDM CT100, login verified via API, Authentik realm untouched; cred in credentials, config backup at CT100 /root/access.bak-2026-06-20.
  • CT118 archivist rpcbind — ✅ DONE: nftables rule restricts port 111 to source 192.168.1.240 (NFS server) only; NFS mount healthy, ruleset persisted. Now 100% LAN-internal.
  • mailcow CT108 — ✅ DONE: backup durable on pi-nas (…/contabo-prewipe-2026-06/mailcow/, sha256-verified), live mail confirmed on edge1; CT108 destroyed (pct destroy 108 --purge, 2026-06-20) — config + disk image purged. edge2 now hosts CT100–107.
  • data disk (92%) — ⏏️ DE-SCOPED: not a gate. OS package updates are roll-back-able (reinstall prior version); the migration-heavy apps that need real rollback (Authentik, Forgejo, Nextcloud, PeerTube) live on cloud/edge2, not data. Optional cleanup only (~6 GB obviously-safe: stale ISO, zimit temp) if ever wanted.

Rollback model (corrected): OS packages → reinstall the prior version (no VM snapshot needed). App DB-migration upgrades (Authentik/Forgejo/Nextcloud/PeerTube) → restore a quiesced DB dump (cheap), since reinstalling the old binary won't unwind a migrated schema.

Phase 1 — Execution Log (2026-06-20)

Status: COMPLETE. 26 guests patched (security-pocket only), every service validated back up, ~600+ security packages cleared, zero data loss. No host reboots (guests only). Method: snapshot-or-DB-dump → security-only apt (apt-get install --only-upgrade from the security pocket) → pct reboot → service-by-service validation.

Guests patched

  • utility: CT100, CT101, CT102, CT103, CT104, CT106, CT107, CT108, CT109, CT112, CT118, CT119
  • cloud: CT120, CT121
  • media: VM105, CT110, CT111
  • data: VM1130
  • edge2: CT100, CT101, CT102, CT103, CT104, CT105, CT106, CT107

(CT107 = headscale — see Critical Finding 1 below.)

Note: many edge2 and cloud CTs' storage does NOT support pct snapshot — DB dump or package-reinstall is the rollback model for those.

Incidental fixes made during Phase 1

  • (a) CT110 peertube — immutable /etc/resolv.conf blocked reboot. The file had chattr +i set (intentional NordVPN DNS protection). Cleared the immutable flag to allow the reboot, then verified the flag was restored and DNS remained healthy after boot.
  • (b) CT111 mcc — DNS hijacked to unreachable MagicDNS. Tailscale accept-dns was redirecting DNS to a MagicDNS address that was not reachable from this CT. Disabled tailscale accept-dns, set 1.1.1.1 / 8.8.8.8 persistently.
  • (c) PostgreSQL on central CT104 moved 16.13→16.14 as part of the security-pocket apt pass.
  • (d) Fleet-wide stale /etc/hosts fix — see Critical Finding 2.

✅ Critical Finding 1 — CT107 headscale reboot-survival — FIXED 2026-06-20

On pct reboot 107, the fleet headscale coordinator crash-looped and required approximately 15 minutes of manual recovery. Two root causes:

  • (a) Docker compose bridge headscale_default came up linkdown after the unprivileged-LXC reboot.
  • (b) Bootstrap chicken-and-egg: Docker port-binds headscale to 100.64.0.38 (tailscale0), but tailscale0 needs headscale (the coordinator) to come up first.

Recovery required: compose down → docker restart → manually add 100.64.0.38/32 to tailscale0 → compose up → re-auth CT107's own tailscale node with a fresh preauthkey → temporarily DNAT vpn.echo6.co through CT107's internal IP to bootstrap, then revert Caddy config and clean up iptables.

Resolution (2026-06-20): Root cause was a triple boot deadlock: (a) headscale/headplane Docker ports were bound to the tailscale IP 100.64.0.38 (which only exists after tailscaled connects to headscale — circular); (b) the headscale-stack.service systemd unit waited on tailscale-online.target (also needs headscale up); (c) only_start_if_oidc_is_available: true blocked startup on Authentik reachability.

Fix applied (all originals backed up .bak-20260620):

  1. Rebound both ports 100.64.0.38:8084/3100 → 10.10.10.25:8084/3100 (CT's static internal IP, always up at boot) in /opt/headscale/docker-compose.yml.
  2. headscale-stack.service → After=docker.service only (dropped tailscale-online.target dependency).
  3. only_start_if_oidc_is_available: false in /opt/headscale/config.yaml.
  4. Repointed edge2 /etc/caddy/Caddyfile vpn.echo6.co upstream (and /admin* headplane) to 10.10.10.25.

PROVEN by a controlled pct reboot 107: headscale self-healed in ~45 seconds with ZERO manual intervention — /health 200, RestartCount 0, clean logs, 32 fleet nodes online.

Known minor leftover (cosmetic, non-blocking): CT107's OWN tailscale client node (100.64.0.38) stays in NoState because its tailscaled ControlURL points at its own IP (http://100.64.0.38:8084) — a self-bootstrap chicken-and-egg. The headscale SERVICE is fully healthy and the fleet is coordinated; CT107 is managed via the edge2 host OOB path, so its own tailnet membership is optional. Candidate follow-up: point CT107 tailscaled ControlURL at https://vpn.echo6.co (now always reachable via Caddy→10.10.10.25) so it self-registers cleanly.

🔴 Critical Finding 2 — fleet-wide stale /etc/hosts broke coordinator connectivity

7 fleet nodes — data, cloud, media, utility hosts, plus caddy CT101, cobalt CT112, and peertube CT110 — had a stale 5.189.158.149 vpn.echo6.co line in /etc/hosts left over from before the 2026-06-19 headscale migration to edge2. This pinned vpn.echo6.co to edge1 (now mail-only), so tailscaled hit Mailcow's TLS cert and could never reach the real coordinator — affected nodes showed OFFLINE in headscale while coasting on persistent WireGuard tunnels (still SSH-reachable, masking the problem).

Fixed 2026-06-20: removed the stale line and ran tailscale up on all 7; all confirmed ONLINE in the coordinator. /etc/hosts.bak-20260620 backups left on each host.

IMPACT on Phase 3: this class of bug means a reboot of an affected host while its control connection was stale would have failed to rejoin the tailnet — the primary lockout risk. Now that all nodes have valid control connections, reboots should re-register cleanly. However: verify each node is ONLINE in headscale before AND after any Phase-3 reboot.

Headscale stale-node cleanup: deleted dead nodes mailcow (destroyed CT108) and a stale peertube duplicate, both on 2026-06-20.

Phase 2 — Execution Log (2026-06-21)

Status: substantially complete; paused 2026-06-21. All high-priority and security-critical app upgrades are done. Only the low-urgency batch items and the cortex AI stack (protected host, own window) remain.

Completed upgrades

All targets below were validated healthy post-upgrade; rollback DB dumps retained on the respective CTs under /root.

Wave 1 — cloud apps

App Host From → To Notes
Immich cloud CT120 2.5.6 → 2.7.5 XSS + ACL-bypass fixes; stack includes Valkey 9 and vectorchord PG
PeerTube media CT110 8.0.2 → 8.2.1 —
Nextcloud AIO cloud CT121 NC 32.0.4 → 33.0.5 (major); mastercontainer updated Major NC version; AIO orchestrated update path

Wave 2 — media stack (media VM105)

App From → To Notes
Jellyfin 10.11.6 → 10.11.11 —
Sonarr → 4.0.17 —
Radarr → 6.2.1 —
Prowlarr → 2.4.0 —
Navidrome → 0.62.0 —
SABnzbd 4.5.5 → 5.0.4 (major) Major upgrade; clean migration
Lidarr DEFERRED Image maintainer hasn't shipped v3 — needs image swap to linuxserver to go v3; left on current
Jellyseerr INTENTIONALLY HELD on preview-OIDC tag Stable lacks OIDC support; switching would break SSO login

Authentik (edge2 CT105) 2025.12.4 → 2026.5.3

Done as 3 sequential hops: 12.4 → 12.6 → 2026.2.4 → 2026.5.3. pg_dump before each hop; migrations clean each time. SSO verified end-to-end by Matt logging into navi. Closes the May-2026 CVE waves. (ak app version 5.2.15.)

Forgejo (edge2 CT103) 14.0.5 → 15.0.3

EOL-branch migration; v15 schema migrations applied cleanly; web 200, API reports 15.0.3. Pre-15 DB dump at /root/forgejo-db-pre15-20260621.sql.

Headscale 0.28 → 0.29.1 (both instances)

  • CT106 (utility, IdahoMesh 3-node mesh) — upgraded first as rehearsal; native systemd binary.
  • CT107 (edge2, fleet coordinator, Docker) — 32/32 nodes reconnected post-upgrade; health 200; boot-survival fix preserved (ports remain on 10.10.10.25). 0.29 breaking changes documented in meshtastic-headscale-runbook (key changes: randomize_client_port removed — was a hard blocker; ephemeral key config nested; minimum Tailscale client 1.80.0; bare ACL * now tailnet-only).

OpenTAKServer (utility CT109) 1.7.10 → 1.7.12

Clean; all 9 TAK services healthy.

Key decision — RabbitMQ LEFT on 3.12.1 (EOL)

Empirically confirmed during the OTS update: updating OTS to 1.7.12 does not touch RabbitMQ — OTS 1.7.12 runs fine against RabbitMQ 3.12.1/Erlang OTP 25. Forcing RabbitMQ → 4.x is the wrong move: OTS is built and tested against 3.12, and 4.x has breaking changes (queue-mirroring removal, feature-flag requirements) that would likely break OTS, which does not appear to support 4.x. AMQP/MQTT ports are localhost-bound, so exposure is low. The EOL 3.12 is a low-priority latent risk to revisit only if/when OTS officially supports RabbitMQ 4.x. NOT a current action item.

Incidental fixes and side-work during Phase 2

  • CT107 boot-survival fix (applied earlier in the effort, during Phase 1 resolution) — rebound headscale/headplane ports to 10.10.10.25, dropped tailscale-online.target dependency, disabled only_start_if_oidc_is_available gate, repointed edge2 Caddy; proven by reboot self-heal in ~45 s. Also corrected CT107's own tailscale node ControlURL to vpn.echo6.co so it self-registers cleanly.
  • Utility node incident (resolved): a batch delete of 9 LVM-thin snapshots triggered an SSD TRIM/discard storm that spiked I/O and load transiently; compounded by CT103 argus running hot (transcription + docker-compose build churn). Matt migrated argus to the cloud node, resolving the issue; utility load returned to normal. LESSON: delete thin-pool snapshots one at a time — not in a batch — to avoid the discard storm.
  • Nextcloud: granted matt@echo6.co the NC admin role. (user_oidc has no group-claim sync, so this is durable across SSO logins.)
  • Radarr: set up a \\192.168.1.160\manual SMB drop folder on the same NFS export as the library (atomic-move imports) for manual movie filing.
  • Snapshot hygiene: all rollback snapshots cleaned up after validation — Phase 1 presec-*, Phase 2 prewave2-*, OTS pre-ots-* snapshots all removed.

Remaining work (next session)

Low-urgency batch:

  • Caddy (edge2 CT101)
  • CouchDB 3.4 → 3.5 (livesync CT104 edge2)
  • valkey-8 sidecar (searxng CT102)
  • NATS 2.14.0 → 2.14.2 (central CT104 utility)
  • MediaMTX 1.13 → 1.19 + Mumble on CT109 (OTS companions, separate from the OTS app)

Protected host — own deliberate window:

  • cortex AI stack: ollama 0.16 → 0.30, open-webui, qdrant, TEI

Separate deferred projects:

  • Nominatim v5 re-import — see nominatim-v5-reimport
  • Optional: clean up retained /root DB dumps (authentik hop1/2/3, forgejo, headscale, OTS, immich, peertube, etc.) once upgrades are confirmed stable

Execution Runbook (Meticulous)

Step-by-step plan to bring every application and package current. Per-app target versions live in Application Currency above; this section is the how/when/order. Execution model: scoped Sonnet task per target → Opus verifies output → report to Matt; approval gate before every load-bearing or reboot step.

Standing guardrails (apply to EVERY step)

  • Protected hosts — cortex & toc — never in a bulk pass. They get a dedicated, manual window. Note the coupling: toc reboot drops cortex (VM150), which is the Claude Code host — expect to lose the control session during that window; drive it from elsewhere or accept the outage.
  • One target at a time. Verify health before moving to the next.
  • Snapshot/backup before each mutating step: pct snapshot / qm snapshot (or vzdump) the guest first; DB dump before any DB-bearing upgrade; run the app's own backup where it has one (Nextcloud AIO, mailcow).
  • No host reboots outside the explicit Phase 3 windows. Security upgrades that set reboot-required are applied but activation deferred to Phase 3. Host OS-security apt for the four cluster nodes is NOT applied in Phase 1 — it rides the Phase 3 full-upgrade window.
  • Rollback for DB-bearing apps = quiesced logical dump + old binary together. For authentik, forgejo, nextcloud, peertube, and immich the rollback unit is a pg_dump / AIO borg / peertube dump taken with the app stopped and the old binary still in place. "Redeploy previous image tag" is NOT valid after forward-only migrations — Django/TypeORM migrations do not reverse, and a pct snapshot of a hot separate-volume DB may restore torn. Record before/after version in the tracking table.
  • Every result must survive a reboot (standing infra policy).

Load-bearing dependencies (drive the ordering)

  • Authentik (edge2 CT105) = SSO. Upgrading it briefly breaks login to everything behind it. Confirm break-glass admin access first; do in a low-traffic window; verify dependent-service logins after.
  • Caddy (utility CT101) = home-services ingress. A restart blips all home services — fold its update into a deliberate moment, not mid-day.
  • Headscale ×2: edge2 CT107 = main fleet tailnet (34 nodes, vpn.echo6.co, ControlURL https://vpn.echo6.co → 184.174.35.153) — HIGH lockout risk. utility CT106 = IdahoMesh sub-tailnet (vpn.idahomesh.com, 3 nodes) — low risk. Upgrade CT106 first as rehearsal. Edge2 CT107 upgrade MUST be driven from an out-of-band path (edge2 host console / direct SSH to 184.174.35.153, NOT over vpn.echo6.co); extend node key-expiry first; dump DB off-tailnet before touching it.
  • Nominatim 4→5 is NOT a routine update — it's a re-import project (see Phase 2C).

Phase 0 — Pre-flight (no app changes yet)

STEP 1 (FIRST — gates everything mutating): Verify break-glass and out-of-band access. Confirm a non-Tailscale, non-Caddy path to every node: Proxmox/Contabo console for edge2, LAN 192.168.1.x SSH for home nodes, PVE noVNC/pct enter for each CT. Confirm PVE/Proxmox web auth is PAM/local, NOT behind Authentik. Prove it: log into Contabo/PVE console; pct enter 105/106/107; confirm LAN SSH; locate break-glass creds in .ref/credentials. Verify Authentik akadmin (private browser session) + each protected app has a local-admin fallback (Forgejo admin user, Nextcloud occ, PDM/Vaultwarden local). Every node + CT shell must be reachable WITHOUT Authentik/headscale/Caddy. Losing the management path mid-run is the single highest-consequence failure mode.

STEP 2: Measure snapshot headroom (per node). Run pvesm status + df -h on data/utility/cloud/media/toc/edge2. Record the storage backend per node (LVM-thin/ZFS/dir-qcow2) and its over-provision failure mode. Hard numeric rule: never start a snapshot below ~20% free; require ≥2× the largest guest's expected write-delta. Cloud node CT120/CT121 free space must be measured now — not assumed. Identify where vzdump lands; if it's data, freeing data is a fleet-wide rollback prerequisite.

STEP 3: Free space on data (92% full, ~73 GB free) — sized to the largest planned snapshot (VM1130 recon-vm / nominatim+overture+padus). Prune stale vzdump/snapshots/ISOs; docker image prune on recon-vm (do NOT remove the pinned nominatim:4.5 image). Confirm nothing deleted is the only copy of a backup or live NAS data. Verify: usage <~85% on snapshot-backing storage; test snapshot succeeds then remove. Blocks data host Phase 3 and canary use.

STEP 4: Verify off-host restorable backups (distinct from per-step snapshots) for every stateful guest: central PG/NATS (CT104), opentakserver PG + RabbitMQ definitions (CT109), forgejo PG + repos (CT103), matrix Synapse PG (CT106), nextcloud AIO borg (CT121), edge2 livesync CouchDB (CT104). At least one copy must live off the node being changed.

STEP 5: Capture pre-change baseline HEALTH snapshot. Record per-target up/down, container states (docker ps/pct/qm status), key endpoint 200 checks, and apt list --upgradable/security counts. Note known oddities: jellyseerr on preview-OIDC dev tag, mailcow CT108 already STOPPED, pinned-stale nominatim, CT118 archivist rpcbind on 0.0.0.0:111.

STEP 6: Decision gates. Close genuinely-open decisions before Phase 1/2/3 can start: daemon-restart tolerance sign-off (Open Dec #7); verify post-cutoff CVE claims against primary advisories with owner+URL per claim; resolve edge2 host-kernel CVE question fully (pin uname -r, check repo kernel availability, decide reboot yes/no — not left conditional); define and announce maintenance windows in America/Boise naming user-facing blips.

STEP 7: edge2 CT108 mailcow — ✅ DONE. CT108 destroyed 2026-06-20 (pct destroy 108 --purge); config + disk image purged. Backup verified durable on pi-nas (…/contabo-prewipe-2026-06/mailcow/, sha256-verified); edge1 confirmed serving mail (MX/A → 5.189.158.149). edge2 now hosts CT100–107.

Phase 1 — Guest OS security packages (no reboot; hosts folded into Phase 3)

Guests only in Phase 1 (low blast radius). The four cluster hosts' OS-security apt rides their Phase 3 full-upgrade window — do NOT patch data/utility/cloud/media host OS in Phase 1 (avoids a mixed-state libc/openssl across the entire Phase 2 app campaign; both phases get cleaned up in one reboot anyway). edge2 host is already fully patched — no action. toc excluded (Phase 3, with cortex).

Per guest target: apt-get update → snapshot → apply security-pocket upgrades → needrestart policy (see below) → verify service health and security-upgradable count hits 0. Kernel/libc security that flags reboot-required → applied, reboot activation deferred to Phase 3.

needrestart policy:

  • Stateful guests — NEEDRESTART_MODE=l (list-only), then deliberate bounce: CT104 central (PG16/NATS/JetStream), CT109 opentakserver, CT110 peertube, VM1130 recon-vm. Stage the packages; take a logical DB dump with the app quiesced; bounce each service deliberately in controlled order. A JetStream restart mid-write loses messages on at-most-once pipelines; a RabbitMQ/redis bounce mid-job is not a clean "blip."
  • Lockout-critical daemons — NEEDRESTART_MODE=l + deliberate controlled bounce: Authentik CT105, headscale instance(s), Caddy CT101/CT111, sshd on any host you're connected through. Run needrestart -r l to see what would restart; bounce deliberately so a libc/openssl bump can't auto-bounce auth/tailnet/SSH daemons out from under the operator.
  • All other guests: needrestart -r a (automatic) is acceptable — seconds of blip, no data risk.

Ordering:

  1. Canary first (utility CT112 cobalt idle, or CT102 searxng) — prove the full procedure on a low-stakes guest before touching never-patched targets.
  2. Worst-first (after canary proven): utility CT119 mesh-territory (91 sec, never patched), CT108 meshai (79 sec), cloud CT120/CT121 guest-OS (101/75 sec), media CT110 peertube (37 sec), utility CT109 opentakserver (31 sec), CT104 central (38 sec, incl. PG 16.13→16.14 + NATS).
  3. Remaining guests: all other utility/cloud/media/edge2 CTs + data VM1130 (recon-vm). Gate data VM1130 step on data disk remediation verified DONE.
  4. edge2 CT106 matrix / CT107 headscale (NO Tailscale client): drive via pct exec from the edge2 HOST (root@184.174.35.153) ONLY — never over service ingress. Treat as own singleton steps, not part of edge2 batch. needrestart -r l; do NOT restart headscaled/synapse unless required.
  5. Control-plane singletons LAST: home-ingress Caddy CT101 and headscale instance(s) — each with DB backup + node-stays-joined verification, never inside a batch.
  6. cortex VM150 (PROTECTED): security apt manually in the toc+cortex window (Phase 3 coordination); not in bulk.
  7. Cross-cutting: Tailscale 1.94→1.98 and Docker CE→29.6 ride along Phase 1 under the same snapshots; EXCLUDE edge2 CT106/CT107 from Tailscale bump (no TS client).
  8. pi-nas: Debian security pocket with linux-image-* and openmediavault* packages held; kernel upgrade rides Phase 3.

Phase 2 — Application updates

Hard isolation rule: {Headscale, Authentik, Caddy, Forgejo} are NEVER in the same maintenance window — at least one of {tailnet, SSO, ingress, git} must always be a known-good recovery path.

2A — Load-bearing SSO and control-plane apps (in this order):

  • Authentik (edge2 CT105) — FIRST, sequential hops, pg_dump per hop.

    • Pre-flight before any hop: (1) Prove break-glass: log in as akadmin in a private browser session; confirm every protected app has a working local-admin fallback (Forgejo admin user, Nextcloud occ, PDM/Vaultwarden local, PVE PAM). (2) Audit/rename duplicate group names — the Django migration fails loudly on dupes. (3) If local /media storage is used, stop the service, mv ./media ./data/media, rewrite compose volume, before starting any new version.
    • Hop sequence (no skipping): 2025.12.4 → 2025.12.6 (backported security) → 2026.2.x → 2026.5.3. One hop at a time: pct snapshot + pg_dump (labelled per hop) → pull new tag → compose up -d → migrations run → verified-login gate (all dependent SSO logins tested) → abort+restore on FIRST migration error. Verify all dependent SSO logins BEFORE upgrading any of the dependents.
    • Rollback: compose down → restore prior tag + dump; or pct rollback for the full CT.

  • Caddy (utility CT101 + media CT111) — early in Phase 2, before home-service app verification. Pair CT101/CT111 in one deliberate low-traffic window (separate from Authentik, Forgejo, and headscale windows). Validate caddy validate; spot-check Caddy↔Authentik path; document a direct Caddy-bypassing Authentik admin URL as break-glass. Verify all home services reachable through the new ingress before proceeding with other app upgrades.

2B — Self-managed updaters (snapshot → run native updater → verify):

  • OpenTAKServer (utility CT109) — app upgrade first, RabbitMQ SEPARATE:

    • Run OTS upgrade script (upgrades OTS + webUI + schema only). Snapshot first. Verify OTS web/API up; CoT works; TAK clients reconnect.
    • RabbitMQ 3.12.1→4.2.8 is a SEPARATE sub-task (decoupled, after OTS app step). The OTS updater does NOT migrate RabbitMQ, Erlang, or feature flags — the EOL RabbitMQ 3.12 would silently remain. Decoupled upgrade: pct snapshot + rabbitmqctl export_definitions → upgrade Erlang to ≥26 → 3.12→3.13.x → rabbitmqctl enable_feature_flag all (confirm all enabled, no classic-queue-mirroring config remains) → only then 4.x. A naive 3.12→4.x jump refuses to boot. Gate "OTS done" on RabbitMQ 4.x up + TAK clients reconnecting before accepting the bundled MediaMTX/Mumble bumps.
    • Rollback: restore snapshot + definitions export.

  • Immich (cloud CT120) — prune old images + docker image prune before snapshot; disable Immich background regeneration until free space is confirmed; docker compose pull && up -d. Do NOT interrupt first-boot 2.5→2.7 DB migration. Also clears Valkey 9.0.2→9.1.0. Rollback = restore pct snapshot + pg_dump taken with the app stopped (not a hot-DB snapshot alone). Verify web, mobile sync, ML.

  • Nextcloud AIO (cloud CT121) — AIO borg backup → stop → update mastercontainer → trigger child update via AIO UI (:8080). A stale AIO may need two cycles. Rollback unit = AIO borg backup (mastercontainer downgrade is not supported — borg is the only path back). Verify occ status 32.0.11; 12 containers green; integrity clean.

2C — Versioned apps (snapshot → bump/upgrade → verify):

  • Forgejo (edge2 CT103) — branch migration 14.x→15.0.3 (separate window from Authentik).

    • Pre-steps: git clone --mirror echo6-docs (and other critical repos) to an OFF-edge2 location; pause the echo6-docs-autocommit cron so recovery docs survive an edge2/Forgejo failure; run forgejo doctor check --all [--fix] to repair stopwatch/tracked_time inconsistencies BEFORE backup+bump. Read 15.0 breaking changes + forward-only FK migration notes.
    • pct snapshot 103 + repos volume + pg_dump + app.ini → bump tag 14→15 → pull/up → migrations → verify.
    • Rollback: restore 14.0.5 image + volume + dump.

  • Headscale 0.28→0.29.1 — utility CT106 FIRST (rehearsal), edge2 CT107 LAST.

    • CT106 (IdahoMesh, 3 nodes, low risk): standard 0.28→0.29 upgrade guide; pct snapshot + DB backup; stop → upgrade binary → config migrate → start. Verify nodes list all joined; verify headplane compatibility.
    • CT107 (main fleet, 34 nodes, HIGH lockout risk — edge2 front door): extend/disable node key-expiry on all 34 nodes BEFORE starting; pct snapshot 107 + dump headscale DB off-tailnet (NOT via vpn.echo6.co); keep a second authenticated SSH session open to 184.174.35.153. Drive entirely from edge2 host console / direct SSH to root@184.174.35.153 — NOT over the tailnet being upgraded. Verify boot chain: edge2 host → CT107 autostart → headscale up → vpn.echo6.co resolves → Caddy proxies. Rollback: restore snapshot via console (not via tailnet).
    • NOT in the same window as Caddy, Authentik, or Forgejo.

  • Media stack (media VM105):

    • qm snapshot 105 before batch. SABnzbd 4.5→5.0: pause/empty queue; audit custom post-proc scripts (empty_postproc removed in 5.x, scripts now run on failed jobs); pin 5.0.4 tag; pull/up; verify queue intact. Lidarr 2.x→3.x: pin v3; pull/up; DB migration on start; verify library+indexers+download client. Sonarr/Radarr/Prowlarr (1-2 ver): routine bumps after SABnzbd/Lidarr. Jellyfin 10.11.6→10.11.11: pin tag; pull/up. Navidrome: routine bump.
    • Jellyseerr preview-OIDC→stable 3.3.0: DECISION GATE before retag. preview-OIDC → stable 3.3.0 is a schema DOWNGRADE; TypeORM stable may refuse to start against a dev-migrated DB. Confirm the correct destination artifact (jellyseerr stable vs "Seerr" successor) and, if OIDC is in active use, confirm 3.3.0 parity. Test stable image against a COPY of the DB first. If parity unclear → STOP and report.
    • Verify each UI; snapshot before, per-app snapshots for majors.

  • PeerTube (media CT110) — quiesce import/transcode jobs; pct snapshot 110 + pg_dump peertube_prod; run PeerTube upgrade script 8.0.2→8.2.1; restart; verify. Rollback = pct rollback + restore dump.

  • cortex AI stack (PROTECTED — manual, own window): ollama 0.16.1→0.30.10 (snapshot models volume — the only rollback after pulling new models; upgrade; verify existing ollama run without re-pull; verify vault-tagger at localhost:11434 and TEI at localhost:8090 still work); open-webui 0.8.1→0.9.6; qdrant 1.16→1.18; tei 1.7→1.9. Pull images, verify.

2D — Lower-urgency batch: caddy (minor), couchdb livesync (3.4→3.5.2), valhalla, photon, kiwix, NATS 2.14.0→2.14.2, valkey-8 sidecar (8.1.5→8.1.8) — snapshot + update as convenient.

Vaultwarden, PDM, WordPress, Synapse/Element/MAS, obsidian, recon-vm Postgres → already current, skip.

2E — Separate project (not in this campaign):

  • Nominatim 4.5→5.3 + Photon 1.1→1.2 (recon-vm) — requires full OSM re-import into a SEPARATE DB/instance; keep nominatim:4.5 image + data until 5.x validated; transient import disk (flat-nodes tens of GB) cannot live on the 92%-full data pool; Photon 1.2 AFTER nominatim 5.x validated, never concurrently. Schedule as its own effort.

Phase 3 — Platform & reboot windows (coordinated, approval-gated)

🔴 BLOCKED — edge2 reboot was NOT permitted until the CT107 headscale boot-survival fix was in place. ✅ CLEARED 2026-06-20 — the CT107 headscale boot-survival fix is applied and proven (see Critical Finding 1 in the Phase 1 Execution Log). The triple boot deadlock (tailscale-IP port bind + tailscale-online.target wait + OIDC gate) has been resolved; headscale now self-heals in ~45 seconds after a CT107 or edge2 reboot with zero manual intervention. The Phase-3 edge2 reboot blocker is lifted. The remaining gates below (corosync quorum + Finding-2 headscale-ONLINE check per node) still apply.

🔴 GATE for every Phase-3 host reboot (Critical Finding 2): Before AND after rebooting any node, confirm that node is ONLINE in the headscale coordinator (headscale nodes list). Stale /etc/hosts entries previously masked coordinator disconnects behind coasting WireGuard tunnels — the stale entries have been removed fleet-wide, but verify ONLINE status at each reboot step to catch any regression. This gate is IN ADDITION TO the corosync-quorum gate below.

Corosync cluster rules (apply to EVERY node reboot in this section):

  • The five PVE nodes (data, utility, cloud, media, toc) are ONE echo6-cluster, quorum = 3 of 5. Losing quorum makes /etc/pve read-only fleet-wide and freezes all VM/CT start/stop/config on every surviving node.
  • Before EACH node reboot: pvecm status must show Quorate: Yes and Expected votes: 5. Also run ha-manager status — if any guest is HA-managed, the reboot triggers fencing/auto-migration rather than a clean local stop/start.
  • Reboot ONE node at a time. Wait for full 5/5 rejoin before the next node.
  • Disable HA migration and NO live migration during the mixed-version window (QEMU 10/11 boundary — running VMs keep QEMU 10 machine type until cold-started; cross-boundary migration fails).

Per-node procedure: apt update && apt full-upgrade (so proxmox-ve/qemu/lxc metapackages pull) → this also clears the held host OS-security packages → reboot → verify pveversion + all guests return with onboot=1. Confirm pvecm status shows 5/5 before proceeding.

Pre-window for each node: vzdump all guests to an EXTERNAL target (not the local pool, never data) so a guest that won't start under LXC 7 can be restored elsewhere. Read PVE 9.2 + LXC 7 release notes for unprivileged-CT/cgroupv2/apparmor breaking changes before the first node.

Canary node order (lowest blast-radius with headroom first): media (single arr VM + peertube, non-auth/non-DB-critical) → cloud (immich/nextcloud, after media proven) → data (after disk remediation verified; its near-full pool can fail the mandatory pre-reboot snapshot — do NOT use as canary until remediated) → utility LAST of the four (carries Caddy ingress + mesh/central stack — deliberately-scheduled full home-ingress + mesh-coordination outage, announce in advance) → toc+cortex LAST AND ALONE (see below).

Post-reboot re-verification gate (per node): after each node boots into 9.2/LXC7, re-run the Phase-2 health checks for every guest that received a major app upgrade on that node (CT120 immich, CT121 nextcloud, CT110 peertube, VM105 arr, CT109 OTS). The substrate changed under them.

toc + cortex — DONE LAST AND ALONE, after all four other nodes are quorate:

  • toc is the 5th cluster vote AND the GPU host for cortex (VM150) AND the management/Claude Code host. Rebooting toc removes a vote and kills the box you'd diagnose from. It must NEVER overlap any other node reboot (toc down + one other = 3/5 → one corosync flap loses quorum).
  • Name and TEST a concrete alternate control point (a non-cortex host with keys + tooling) BEFORE this window. Stabilize the tailnet well before it — never in the same period as a headscale upgrade.
  • cortex steps IN ORDER:
    1. qm snapshot 150 pre-nvidia + vzdump (from toc, before anything changes)
    2. apt --only-upgrade nvidia-container-toolkit; nvidia-ctk runtime configure; restart docker → verify --version=1.19 + docker run --gpus all nvidia-smi
    3. apt --only-upgrade nvidia-driver-580 nvidia-dkms-580; DKMS rebuild → verify dkms status shows installed + nvidia-smi=580.167 BEFORE rebooting toc. Keep the old driver package installed as a reinstall fallback.
    4. cortex Phase 1 security apt (if not already done in its own window)
  • Then reboot toc → verify toc rejoins (pvecm status 5/5) → verify VM150 autostart + cortex GPU passthrough return → final AI-stack health check (driver 580.167; all 5 containers; ollama/tei/qdrant/open-webui; vault-tagger+TEI engines; TS online; Docker 29.6).
  • The Claude Code host goes down here — run this step from the alternate control point.

pi-nas — standalone window, TWO reboots:

  • Confirm physical/serial console access (no remote KVM on an RPi); export config.xml off-box; confirm pi-nas is not mid-sync as a Syncthing/backup target before each reboot. Back up /boot + /boot/firmware; keep the old kernel installed as fallback.
  • Reboot 1: OMV 8.1→8.4 via OMV's own update path (NOT raw apt full-upgrade — use OMV UI Update Mgmt or omv-upgrade) → reboot → verify shares/SMB/NFS/omv-salt healthy.
  • Reboot 2 (AFTER reboot 1 verified): kernel 6.12→6.18 — apt install linux-image-arm64 (unhold); update bootloader; reboot ON APPROVAL → verify uname -r=6.18; LAN+tailnet up; shares mount; Docker up. Rollback: boot retained 6.12; restore /boot; on-site SD reflash.
  • Independent of cluster windows.

edge2 — CONDITIONAL (CT107 boot-survival blocker CLEARED 2026-06-20):

  • Previously also blocked on the CT107 headscale boot-survival issue — that blocker is resolved; headscale survives a CT107 or edge2 reboot and self-heals in ~45 seconds (see Critical Finding 1, fixed 2026-06-20).
  • Reboot only if Phase 0 resolved the DirtyFrag/copy.fail CVE question as "yes, needs a newer kernel" (Open Decision #5 recorded "no action / no reboot" — edge2 host already fully patched). If a reboot is ever required: give it a dedicated window AFTER Authentik CT105 + headscale CT107 are upgraded and verified; announce SSO+tailnet downtime; drive from a non-tailnet path; confirm all CTs auto-start. edge2 is a single SPOF for ingress — no failover. Do NOT fold into cluster windows.

Phase 4 — Cross-cutting (fold into earlier phases)

  • Tailscale 1.94→1.98 fleet-wide — rides along Phase 1.
  • Docker CE →29.6 wherever installed — rides along Phase 1/2 under the same snapshots.

Key Facts & Top Risks

Cluster & control-plane facts

  • One corosync cluster. data, utility, cloud, media, toc are echo6-cluster — quorum 3 of 5. Every Phase 3 reboot is gated on pvecm status (Quorate:Yes, expected votes=5); ONE node at a time; confirm 5/5 rejoin before next.
  • toc coupling. toc is the 5th cluster vote + GPU host for cortex VM150 + the management/Claude Code host. toc+cortex are the FINAL Phase 3 action, alone — never overlap another node reboot.
  • Headscale topology (resolved). Main fleet tailnet (34 nodes, ControlURL vpn.echo6.co) = edge2 CT107 (Headscale 0.28.0) — HIGH lockout risk; upgrade LAST, drive from out-of-band. Separate IdahoMesh sub-tailnet (vpn.idahomesh.com, 3 nodes) = utility CT106 — low risk; upgrade FIRST as rehearsal. No routing through old-Contabo.

Top risks (critical first)

  1. Headscale edge2 CT107 self-lockout (CRITICAL) — upgrading the main tailnet over the tailnet itself loses the control path to 34 nodes. Mitigation: out-of-band only (edge2 host console / direct SSH 184.174.35.153), key-expiry extended, DB dumped off-tailnet, boot chain verified.
  2. Corosync quorum loss (CRITICAL) — two nodes down simultaneously = quorum lost, /etc/pve read-only fleet-wide. Mitigation: one node at a time, pvecm status gated before each, HA disabled during window.
  3. Authentik SSO migration chain (CRITICAL) — 4-hop irreversible Django migration sequence; a failed hop with no per-hop pg_dump can strand the entire SSO surface. Mitigation: pg_dump per hop, verified-login gate, break-glass proven before starting.
  4. data node snapshot-space exhaustion (CRITICAL) — 92% full; a snapshot failure mid-upgrade leaves the guest in a half-upgraded, unrollbackable state. Mitigation: disk remediated to <85% before any snapshot on that node; do not use as Phase 3 canary until resolved.
  5. RabbitMQ EOL/won't-boot (HIGH) — 3.12→4.x direct jump refuses to start; 3.x has no security backports. Mitigation: staged hops (3.12→3.13.x→feature-flags→4.x), decoupled from OTS updater.
  6. Forward-only DB migrations / false-rollback assumption (HIGH) — "redeploy previous image tag" is NOT a valid rollback for authentik, forgejo, nextcloud, peertube, immich after a migration runs. Rollback = quiesced logical dump + old binary together.
  7. toc reboot drops cortex + management host (HIGH) — cortex is the Claude Code host; losing it during diagnosis is double-jeopardy. Mitigation: alternate control point tested before window; cortex NVIDIA/DKMS verified before toc reboot; toc+cortex done last and alone.
  8. pi-nas non-boot after combined kernel+OMV change (HIGH) — RPi has no remote KVM; a bad combined update requires on-site SD reflash. Mitigation: two separate reboots (OMV first, kernel second); retain 6.12; /boot+/boot/firmware backed up; physical access confirmed before each.

Coverage Notes

  • Complete: all five PVE-9 nodes (data, utility, cloud, media, toc), edge2, cortex, pi-nas, and all discovered guests/containers.
  • Excluded: edge1 (the rebuilt ex-Contabo, mail-only) — mid-rebuild/maintenance at time of audit; re-audit once it settles.
  • Incomplete: WordPress (CT101) plugin and theme status — requires WP-CLI; not assessed.
  • Method: read-only throughout — SSH / pct exec, apt list --upgradable, docker manifest inspect for same-tag drift. Floating/pinned-tag caveats noted inline where drift could not be confirmed.
