Same abstract PVE server I set up before. Recently I noticed the default ZFS pool had gone Degraded. You can see pretty clearly that one drive is toast. Since I built it as RaidZ1, one drive failure is survivable, so in theory I just swap the drive.

The OMV NAS at work suddenly started acting up, telling me it couldn’t mount /dev/md0. That knocked out both Plex and Syncthing on the NAS, and the error message itself was weird as hell: mount: /dev/md0: more filesystems detected. This should not happen, use -t to explicitly specify the filesystem type or use wipefs(8) to clean up the device. Multiple filesystems? What the hell is that supposed to mean? Was the Raid on this piece-of-junk office NAS about to die on me again?
