 ### Recent operator maintenance (2026-03-28)
 
+- **Fleet checks (same day, follow-up):** Ran `collect-storage-growth-data.sh --append`, `storage-monitor.sh check`, `proxmox-host-io-optimize-pass.sh` (swappiness/sysstat; host `fstrim` N/A on LVM root). **Load:** ml110 load dominated by **Besu (Java)** and **cloudflared**; r630-01 load improved after earlier spike (still many CTs). **ZFS:** r630-01 / r630-02 `rpool` ONLINE; last scrub **2026-03-08**, 0 errors. **`/proc/mdstat` (r630-01):** RAID devices present and active (no resync observed during check).
+- **CT 7811 (r630-02, thin4):** Root was **100%** full (**~44 GiB** in `/var/log/syslog` + rotated `syslog.1`). **Remediation:** truncated `syslog` / `syslog.1` and restarted `rsyslog`; root **~6%** after fix. Ensure **logrotate** for `syslog` is effective inside the guest (or lower rsyslog verbosity).
+- **CT 10100 (r630-01, thin1):** Root **WARN** (**~88–90%** on 8 GiB); growth mostly **`/var/lib/postgresql` (~5 GiB)**. **Remediation:** `pct resize 10100 rootfs +4G` + `resize2fs`; root **~57%** after. **Note:** Proxmox warned thin **overcommit** vs VG — monitor `pvesm` / `lvs` and avoid excessive concurrent disk expansions without pool growth.
+- **`storage-monitor.sh`:** Fixed **`set -e` abort** on unreachable optional nodes and **pipe-subshell** so `ALERTS+=` runs in the main shell (alerts and summaries work).
 - **r630-01 `pve/data` (local-lvm):** Thin pool extended (+80 GiB data, +512 MiB metadata earlier); **LVM thin auto-extend** enabled in `lvm.conf` (`thin_pool_autoextend_threshold = 80`, `thin_pool_autoextend_percent = 20`); **dmeventd** must stay active.
 - **r630-01 `pve/thin1`:** Pool extended (+48 GiB data, +256 MiB metadata) to reduce pressure; metadata percent dropped accordingly.
 - **r630-01 `/var/lib/vz/dump`:** Removed obsolete **2026-02-15** vzdump archives/logs (~9 GiB); newer logs from 2026-02-28 retained.
