TAILSCALE IPv6. `tailscale status` had been reporting, continuously:
2 add route failures; first was: permission denied
adding address fd7a:115c:a1e0::6/128 from tunnel interface: permission denied
with tailscale0 carrying only 100.64.0.6/32 while headscale had assigned it
an IPv6 address it could not use.
Not a capability problem -- tailscaled runs as root with the full bounding
set. /etc/sysctl.conf:59 sets net.ipv6.conf.default.disable_ipv6=1, and
`default` is inherited by NEWLY CREATED interfaces; tailscale0 is created at
daemon start, inherits it, and the kernel returns EPERM for every attempt.
Fixed with a scoped systemd drop-in rather than flipping the global default.
That line carries no comment, but IPv6-off-by-default on a host with ~26
docker bridges reads as deliberate, and changing it would hand IPv6 to every
future bridge as a side effect of fixing Tailscale.
⚠ It must be ExecStartPost, not /etc/sysctl.d. A sysctl.d entry for a
per-interface key is applied at boot, BEFORE tailscale0 exists, and is
silently ignored -- the setting would look present and do nothing.
Also learned: setting the sysctl on the LIVE interface is not enough.
tailscaled only attempts the address at startup or on a netmap change, so
the verify failed for 60s until the daemon was restarted. Restart is part
of the operation, not an afterthought.
Verified: fd7a:115c:a1e0::6/128 present on tailscale0, health clean, mesh
and services (arbo, ytvc) up.
README. It documented the pre-headscale topology as current -- "Reachable
IP: 10.100.79.3 (WireGuard tunnel endpoint)", "No direct LAN access", and a
refresh caveat telling you to bring WG up. That sends anyone triaging this
host to the wrong layer, which is the exact tax the file exists to prevent.
Now: mesh primary at 100.64.0.6, LAN 10.6.110.50, and wg0 documented as
STILL UP with a live peer -- tailscale uses that address as its direct
endpoint, so it is load-bearing, not vestigial.
Recorded with it, because these cost hours tonight and will cost them again:
- Irvine is a TENANCY behind a Fortinet PFI does not control. Its TLS
inspection breaks Tailscale's relay and control channels (41 cert
warnings/week, 4 control-plane episodes in 14 days). Usually invisible
because direct peer paths carry the data. No fix on our side.
- Diagnose reachability with `tailscale ping`, NOT the status output:
headscale said "online" and status said "active, 19.7 GB" while nothing
on the host answered. Both are last-known state; only a round trip is
liveness.
- The ~26 docker bridges make tailscaled report captive portals.
Two stale claims corrected: the hostname rename it called "pending" is done,
and `ollama` is listed as running on :11434 when it is gone -- verified, no
unit file, nothing listening, no process. It is banned fleet-wide.
eshpfi-management
Infrastructure management workspace for the PFI fleet (plus the ESH home-lab host). Tracks server state, canonical Docker Compose stacks, per-host configs, and the tooling that moves them around.
See CLAUDE.md for the full set of conventions and the rules Claude Code sessions follow when working here.

Common tasks
Refresh one host's snapshot:
scripts/refresh-server-info.sh ana-docker
Refresh all hosts:
scripts/refresh-server-info.sh all
Refresh all Proxmox nodes (separate flow — captures VM/LXC/backup-coverage):
scripts/refresh-proxmox-info.sh all
Add a new host:
scripts/add-host.sh <name> <ip-or-user@ip>
scripts/refresh-server-info.sh <name>
Validate discovery (without hitting the network):
scripts/refresh-server-info.sh --validate-only all
Push a stack to a host (with diff + confirm):
scripts/deploy-stack.sh <host> <stack>
Pull every server's compose/conf trees into stacks-mirror/ (not committed — see .gitignore):
scripts/sync-stacks.sh all
Bootstrap a new fleet repo from this one:
scripts/fork-fleet.sh ~/development/<other-fleet>-management
# optional: override the fleet-name baked into the skeleton CLAUDE.md / README
scripts/fork-fleet.sh ~/development/<dest> <fleet-name>
Mirrors the reusable tooling (everything under scripts/, the
generic playbook templates, .gitignore, conventions section of
CLAUDE.md) into the destination dir, strips fleet-specific content
(servers/, stacks/, configs/, fleet-named playbooks
(deploy-*, decouple-*), docs/orientation.md, docs/runbooks/,
docs/pfi/, STATUS.md, host-pinned helper scripts), regenerates
skeleton CLAUDE.md / README.md / STATUS.md with the new fleet
name, and initializes a fresh git history with one "Initial commit".
The script does not create a gitea remote or push — namespace +
repo name are an explicit manual step. The "next steps" output prints
the exact tea repo create + git remote add + git push commands
to wire it up when ready.
Backup pipeline
Backups are driven by per-host resticprofile configs under configs/restic/<host>/, scheduled via systemd timers on each host:
- Writes: each host backs up to its site-local rest-server (
rest-server-anaorrest-server-nh3), over HTTP basic-auth. - Authentication: shared
.htpasswdfile on both rest-servers, one entry per host; credentials stored in/etc/restic/restic.envon each client host. - Encryption: per-host client-side passphrase in
/etc/restic/password(unique per repo; losing it = losing that host's backups). - Visibility: Backrest (
http://10.250.50.70:9898) shows every repo for browsing/restore. - Schedule: backup at 01:00 daily,
forgetat 03:00 daily, weeklycheck --read-data-subset 10%on Sundays. - Prune: manual ceremony (rest-server runs with
--append-only, which blocks destructive prune ops). - Off-site: cross-site rsync between the two rest-server data dirs is planned (not yet implemented).
Coverage status (as of 2026-04-29)
Goal: every Docker host + configs + every database covered, not just VM images.
| Layer | State |
|---|---|
| VM-level (Proxmox vzdump) | ✅ All running guests covered across pfi-pve / nh3-pve / esh-pve-nas; esh-pve has VMID 108 uncovered |
| ana-docker restic (host files + DBs) | ✅ configs/restic/ana-docker/ with pre-backup hooks for synapse / seafile / vaultwarden-pg / gitea (native dump) / openwebui |
| fv-ml1 restic | ✅ configs/restic/fv-ml1/ — bare-metal host files (no DB hooks needed) |
| nh3-docker restic | ✅ Light — no DB hooks needed |
| esh-docker-vm restic | ✅ With DB hooks for paperless-postgres (external), home-assistant + pgadmin + uptime-kuma (host-side sqlite3), calibre-web-automated (in-container sqlite3) |
| vm-esh-nas restic | ✅ Light — NFS mounts explicitly excluded |
| nh3-dev (workstation) restic | ✅ /home/lkraven + /etc with language-toolchain and build-output excludes |
| irv-ml1 restic | ✅ Cross-site to rest-server-nh3 via WireGuard |
| esh-vm-db restic | ✅ With pg_dumpall + mongodump pre-backup hooks |
| Cross-site redundancy | ✅ ana-nas → nh3-nas rsync at 04:00 daily; nh3-nas → ana-nas at 05:00 daily (configs/rsync/) |
| Prune ceremony | ✅ Quarterly manual ritual documented in docs/runbooks/nh3-prune-ritual.md (DSM-mediated --append-only toggle) |
| offen/docker-volume-backup sidecars on esh-docker-vm | ❌ Remove once restic proves itself (~1 week of clean runs) |
Authoritative vs. mirror
- Authoritative: files on each server under
/opt/docker/compose/<stack>/and/opt/docker/conf/<stack>/. - This workspace: source-of-truth copies under
stacks/<name>/(hand-curated), and a gitignored mirror understacks-mirror/pulled bysync-stacks.sh.
Edit in stacks/, push with deploy-stack.sh. Never commit stacks-mirror/ — it can contain embedded plaintext secrets from upstream compose files that haven't been audited yet.
