Backups fail with error: "File-System could not properly remount. Please contact Support immediately and submit a ticket"
Figure 1: File System could not properly remount error banner
- Datto SIRIS
- Datto ALTO
The ZFS file system's storage volume has become unmounted on the Datto.
Most often, this occurs if during a restore or device operation (File Restore, Screenshot, Running Virtual Machine, Bare Metal Restore) the device experienced an unexpected shutdown.
A quick solution is to simply reboot the device and see if the error persists. Alternatively please submit a ticket or call Datto Technical Support as a Datto Technical Support team member can remotely remount the volume. It is rare to have this error re-occur, if it does please reference this when contact Datto Technical Support.
