+## Update: 20:45 — Jupiter maintenance + OwnCloud cache migration (Mike, DESKTOP-0O8A1RL)

+### Jupiter health check
+
+Ran full audit of Jupiter (172.16.3.20, Unraid 7.1.4):
+
+**Issues found:**
+1. **MariaDB-Official crash-looping** (143 restarts) — `Errcode 28: No space left on device`
+2. **Discourse (app) crash-looping** (100+ restarts) — same root cause
+3. **Root cause: BTRFS cache drive data chunks at 99.08%** — Unraid's `shareFloor=195400000` (195 GB minimum free) on appdata share rejecting writes because cache free was only 175 GB
+4. **OwnCloud data (589G) filling cache** — share set to `shareUseCache="yes"` (prefer cache), mover supposed to move to array but SMB lock from OwnCloud VM prevented mover from touching any files
+5. **Unraid 7.1.4** — update to 7.2.4 available (Uranus already on 7.2.4)
+6. **binhex-overseerr** container exited 21h ago
+7. **No UPS monitoring** — no apcupsd running
+8. **SMART: all PASSED** on checked drives (HGST, WDC, Samsung 870 EVO cache)
+
+**Why mover wasn't working:**
+- Mover runs hourly (`0 */1 * * *`) via cron
+- OwnCloud VM connects via SMB to `/mnt/user/OwnCloud/` share
+- Active SMB session (from 172.16.3.22 since Apr 15) keeps ALL files "in use"
+- Unraid's `move` binary detects in-use files and silently skips them
+- Result: 589G stuck on cache indefinitely, mover logs nothing (logging was off)
+- Fixed: `shareMoverLogging="yes"` enabled for future visibility
+
+### OwnCloud cache-to-array migration (IN PROGRESS)
+
+**Executed Option A (brief downtime):**
+1. Stopped OwnCloud VM (`virsh shutdown OwnCloud`) — confirmed `shut off` state
+2. Verified SMB disconnected (`smbstatus` clear)
+3. Launched detached rsync: `rsync -av /mnt/cache/OwnCloud/ /mnt/disk7/OwnCloud/`
+4. Migration script at `/tmp/migrate-owncloud.sh` handles:
+   - rsync completion check
+   - Cache copy deletion (`rm -rf /mnt/cache/OwnCloud/`)
+   - Share config update (`shareUseCache="yes"` -> `"no"`)
+   - OwnCloud VM restart
+   - MariaDB-Official + Discourse container restart
+
+**Progress as of save:** 533G / 589G copied (~90%). ETA ~14 min.
+**Expected result:** cache usage drops from 82% to ~12%. MariaDB + Discourse auto-recover. Mover no longer needed for OwnCloud.
+
+### /mode command fix
+
+- `/color` cannot be invoked programmatically by Claude — it's a built-in CLI command
+- Updated `.claude/commands/mode.md`: on mode change, Claude says `[MODE -> infra] /color red` so user can paste the command
+- No hook-based automation feasible for this

+### Pending
+
+1. **OwnCloud migration completing** — monitor will report DONE, then verify MariaDB + Discourse come up
+2. **Unraid 7.1.4 -> 7.2.4 update** — needs reboot, schedule maintenance window
+3. **Restart binhex-overseerr** — or remove if unused
+4. **UPS monitoring** — install apcupsd if UPS connected
+5. **Verify parity** — couldn't read parity status via CLI, check Unraid UI
+6. **All prior pending items from earlier this session** still open (Howard Gitea account, Len's deployment, etc.)
