Live validation caught what the tests could not. On demo-felhom the recipe read
namespace "root" with namespace_state "resolved" — confident and wrong, a worse
shape than the original defect.
mergeConfig overlays the cluster storage config onto the node entry through a
hand-listed set of fields and Namespace was not among them. NodeStorage does not
return the namespace at all, so PBSNamespace always read "" and latestPBSCoord
correctly treated that as the root namespace.
Every v0.118.0 test built StorageTarget values directly — including the two
through Collector.Collect(), which inject a fakeObserver — so nothing crossed the
merge. Two new tests drive the real Observe path with PVE's actual split returns
and table the merge itself. Red-proof: dropping the added line fails both.
Suite rc=0, 29 packages, 0 FAIL.
Operator ruling 2026-07-13: walk the root's backing device through /sys/block/<dev>/slaves
recursively down to physical disks (dm AND md; topology, never VG names); those + any mounted-ESP
holder are system; the all-system fail-safe returns to being the WALK-FAILURE error case only.
SAFETY DIRECTION: a root-backing disk classified candidate is made impossible — per-branch
conservatism (any unresolvable slave fails the WHOLE walk -> ok=false -> the unchanged all-system
path).
- physicalDisksOf/walkSlaves in role.go (symlink canon -> wholeDiskOf fast path -> recursive
slaves walk; cycle/depth guard; non-/dev sources unwalkable)
- HostReader.BlockSlaves(name) — the ONE new seam method; ProcHostReader reads
/sys/block/<name>/slaves; all four test fakes mirror it
- role_walk_test.go: signature table (root-backing disk ALWAYS system across legacy-LVM /
md-raid / EFI+raw / EFI+LVM / nested dm-on-md — NEVER weaken) + dead-wizard-lives +
dangling-slave fail-safe (real sysKnown=false path) + cycle + empty-slaves; red-proofs A/B/D
run->fail->revert (recorded in REPORT)
- §3 spike transcripts (drill legacy: dm-1->sda3->sda; felhom-pve: ESP+walk agree on sda ->
byte-identical regression); caller audit: none relied on all-system as a feature
- format/mkfs paths, data-bearing guards, wizard UI untouched
Surfaced preparing the live USB validation on demo-felhom:
- observe.go: an unmounted removable dir-storage no longer falls through to the ROOT fs
for its backing device/UUID — durable_id was becoming uuid:<root-uuid> (a DR mis-id that
would re-attach the wrong disk). Now derived only from the target's own mountpoint;
unmounted → no device + stable store:<name> durable_id. Removed containingMountDevice.
- watchdog.go: remember the fs-UUID observed while attached and backfill it onto the
re-mount target, so re-mount works even if the known-set cache refreshed mid-drop
(doc 03 §7 "sourced from the existing definition").

Fill the slice-3 storage_targets stub and add the fast-poll storage watchdog.
Read-only this phase; the host-root surface (mounts/SMART/grow/destructive gate)
is Phase B. Hub-owned desired manifest is slice 10, so reconcile against it is
built-but-unfed.
- internal/storage: StorageTarget wire contract, durable_id derivation per type,
HostReader seam (procfs/sysfs, root-free), Observer (storage_targets from
ListStorage/NodeStorage + host reads, lvmthin thin-pool fill), and the watchdog
(third daemon goroutine; debounced out-of-band report on a known target's
attach/disconnect transition).
- proxmox.Storage: additive parse-only config fields (durable_id sources).
- collector StorageObserver seam; Loop.SetTrigger out-of-band report; daemon runs
the watchdog as a third goroutine; StorageConfig knobs.
- cross-repo golden kept byte-identical with felhom.eu/hub; bidirectional key-set test.
