The Synology offsite backup target (/mnt/synology-backup, surfaced via the PVE host NFS mount) sits at ~94% by design and was firing NodeFilesystemFull continuously. Per user request, raise the threshold to 95% (<5% free). NOTE: NodeFilesystemFull is a global node-filesystem rule, so this also loosens the warning on k8s node/system disks; BackupDiskFull (sda /mnt/backup) stays at 85%. Also adds docs/runbooks/synology-storage.md: how to assess Synology usage WITHOUT du (Storage Analyzer weekly CSVs, df/btrfs/qgroup), btrfs async/snapshot-pinned reclaim, the 2026-06-05 capacity assessment (94% full; Backup share 4.42TiB), and ~500GiB of homelab cleanup candidates (redundant gphotos Takeout, old laptop VM images, archives).
