Supervised runbook execution. No code change, no version bump.
felhom-offsite moved from ep0's 40 GB root disk (/srv/pbs-felhom) to a
dedicated 100 GB Hetzner Cloud Volume (/mnt/pbs-datastore, ext4 -m 0,
by-id fstab, relatime). Datastore NAME unchanged, so the PBS-DR
descriptors, per-box storage ids, ACLs and namespaces are untouched.
Capacity: 37.2 GB -> 98 GB total, 28.9% -> 13% used, headroom to the 80%
warn 19 GB -> ~65 GB. This CLEARS the R-82 Phase 0 P0.3 STOP. Per-tenant
encryption still precludes cross-customer dedup, so the slope is
unchanged - the volume buys runway, not a better cost model.
Verified: byte totals and chunk counts identical (9748), 7/7 snapshots
across all three namespaces, backup:backup ownership, clean itemised
dry-run, full verify job TASK OK with 0 errors, and a restore round-trip
(source_tier pbs, pass true, mount_parity ok, clean teardown).
Nothing deleted - the original 13 GB stays at /srv/pbs-felhom as the
rollback until a new weekly backup lands. GC deliberately not run.
Three findings recorded:
- the `scratch` datastore points at a non-existent path (pre-existing;
now logs ENOENT every start) - operator decision
- the runbook's S6 guard test proves the wrong proposition:
RequiresMountsFor re-mounts rather than refusing, so the test only
bites when the device is genuinely unavailable (re-run that way, and
the refusal was observed) - amendment recommended
- S11: storage box u629193 has no live backup path, BUT ep0 carries an
enabled sshfs mount unit against it that must be removed before the
box is deleted
Deviations: the volume arrived pre-formatted and mounted; S8 ran on
demo-felhom rather than demo-hp (no SSH key for demo-hp); the window was
contended by a stale in-memory 10-minute restore-test cadence whose
config had already been reverted on disk.

Read-only gate. No code, no backup triggered, no config changed.
P0.1 weekly CONFIRMED: the only 7-day-exposed state is the non-SMB half of
settings.json (storage_paths, app_backup toggles, notification prefs,
password_hash, launcher token) — none catastrophic, all recoverable. The two
items that would have overturned it, encryption.key and the offbox
credentials, are STABLE files unchanged since first boot, so a 7-day-old copy
is byte-identical. Everything referentially coupled to app state is carried
daily by Tier-1/2/3, and Tier-3 offsite was verified running and ok on both
production boxes. CONDITIONAL: drill-r50 has offsite:null, so the verdict does
not hold there.
P0.2 RESOLVED, benign: PBS returns HTTP 200 with zeroed usage to the
namespace-scoped token (DatastoreBackup, not Datastore.Audit), so PVE prints
0/0/0. Ground truth via the hub ep0 df op: 28.9% of 37.2 GB. Writes work —
the 07-18 snapshot is owned by this token, 9.74 GB, verify ok.
P0.3 STOP: 37.2 GB datastore, 10.8 GB used, 80% alert at 29.8 GB. Encrypted
per-tenant backups do not dedup across customers. Current 3 boxes project to
~15-21 GB weekly keep-3; each additional customer costs ~5-10 GB, so the 80%
alert fires at roughly the SECOND additional customer — inside the alpha
horizon. Needs a ruling on datastore size / retention before recurring writes.
