B6 #3 — the data disk at 100 % during a backup (2026-10-20 18:11–18:43 UTC) — AS EXPECTED, one text gap
The one real night belongs to B5, so „Mentés most" stood in for the nightly backup (plan amendment, written before). The filler went onto a new share „Teli" with Felhőmentés OFF (nothing large left the house) and was deleted afterwards.
| UTC | what | observed |
|---|---|---|
| 18:13–18:39 | 18 × 10 GiB copied over SMB by the family | ~110–150 MB/s; no freeze this time |
| 18:36:13 | the box's fill-watch | ok → warning — 89 % used … notifying the customer |
| 18:39:38 | file 19 | the copy fails with „NT_STATUS_INVALID_NETWORK_RESPONSE closing remote file" — not a clear „the disk is full" to a Windows/Mac user; 856 KB left |
| 18:40:08 | „Mentés most" on the full disk | Immich, Nextcloud, Paperless REFUSED before writing („below the reserve: 97 % used or 1.0 GiB free"); the 5 apps on the system disk backed up; events recovery_unit_capture_failed ×3 and backup_run_failures „3 of 8 apps failed … immich, nextcloud, paperless-ngx" |
| 18:40 | older copies | the 17:21 local restore point still offered — nothing deleted to make room |
| 18:40:57 | filler deleted | 190 GB free again |
| 18:41–18:43 | „Mentés most" | all 8 apps captured (105 s) |
System disk at 97 %: NOT run. No household front door writes tens of GB onto the guest's system disk (49 GB); the „Belső tárhely" area is its own volume, so filling it would not fill the system disk. Reason recorded, not invented.
