snapshot notifications from BTRFS

Quote from theking2

I've reformatted an external BTRSF formatted disk. Reformatted it as NTFS. Yet when I connect it OMV sends out hourly messages like below. How do I stop this no longer valid cron job?

Code

/etc/cron.hourly/openmediavault-cleanup_sf_snapshots:
ERROR: not a btrfs filesystem: /srv/dev-disk-by-uuid-89ddba4e-f8f4-4afb-af91-a4761cf08817

There is still a mount point configuration for the now non-existing Btrfs filesystem in the database. Delete it and you'll get rid of these messages.

Keep in mind that the database is the source of truth in OMV.
