UniFi UNAS-Pro Snapshot Issues#

The August 2, 2026 emergency pool migration copied nine shared drives into ordinary directories instead of Btrfs subvolumes. File access worked, but snapshots and quota operations failed. The repair is to replace each affected share root with a Btrfs subvolume and ensure its separate snapshot destination exists. GoogleCloudSync, Documents, Immich, Books, HomesDSM, Musique, Nadine, and Software were repaired on October 10, 2026. Photos was repaired on October 11, 2026.
