Raw Blame History

Kernel night 9→10 October 2026 — read-back (2026-10-10, read only)

demo-hp demo-felhom
Told (hub os_kernel_notice; household mail) 7.0.14-22-pve, mail 3 of 3, 2026-10-09 08:39Z 7.0.14-23-pve, mail 1, 2026-10-09 07:00Z (mail in the inbox 07:00:29Z)
Staged (agent + hub os_kernel_step) 02:42:15Z 02:44:26Z
Restart started (agent WARN) 02:42:20Z 02:44:30Z
Judged healthy, default now (agent; hub event) 7.0.14-22-pve, 1 m 59 s after the agent started (02:47:10Z) 7.0.14-23-pve, 39 s after (02:46:03Z)
Running (uname -r, 05:28Z) 7.0.14-22-pve 7.0.14-23-pve
Default after (grub.cfg set default, /etc/default/grub.d/zz-felhom-kernel-default.cfg) 7.0.14-22-pve 7.0.14-23-pve
Apps down for the restart ~3 min 28 s: 02:42:20Z → last app 02:45:48Z (Docker StartedAt); metrics gap 02:42:17–02:45:37Z, all 21 back 02:46:35Z ~65 s: 02:44:30Z → opengist 02:45:35Z (Docker StartedAt); metrics: one sample missing (02:44:41)
Other stops that night local backup tier 02:31Z, 6 app containers for under ~1 min (metrics 21→15→21); 00:30Z 3 containers ~1 min; 02:15Z 1 container ~1 min none seen (5 containers every sample)
False alarm none (hub: no error/warning/backup-missed event since 2026-10-09 10:00Z; inbox: no demo-box alarm; the positive control: Tester 2's expected 05:00 mails arrived) none (same two channels; last night's „backup missed" did not return)

„Approve kernel set": NOT shown. The System page's kernel candidate reads „the ring-0 boxes booted different kernels (7.0.14-23-pve, 7.0.14-22-pve)" — no /os/approve-kernel form on the page (template system.html:77). demo-hp is due 7.0.14-23-pve, „not told yet (mails 09–20 h)".

Noted, not a fault: demo-hp dd invoked oom-killer at 02:39:28Z is the planned post-Docker-update memory probe (os-apply: OOM-CHECK result=pass). A stale saved_entry=…7.0.14-20-pve in demo-hp's grubenv is not read (the grub.cfg default is a fixed entry, not saved).

Channels: host journals (*-night.txt, trimmed of the 20-second reconcile line and kernel noise), uname/grub (*-night.txt head), Docker StartedAt (*-apps.txt), the controller's metrics.db (*-metrics.txt), the hub DB (copy with -wal/-shm, read, shredded — hub-events.txt), the hub System page (kernel lines only — hub-system-page-kernel.txt), the Gmail inbox.
