Update to OMV looks to have eliminated filesystem

hi,

I updated OMV through CLI using omv-update and after the update and restart of the device, one of the drives filesystems is showing as no longer mounted, and Status - Missing. It was originally an esxt4 filesystem disk sdb. Tried to mount this manually through the CLI as the option is greyed out through the UI but if failed.

Results below:

root@mediaserver:/# mount -t ext4 /dev/sdb /mnt/test
mount: wrong fs type, bad option, bad superblock on /dev/sdb,
missing codepage or helper program, or other error

In some cases useful info is found in syslog - try
dmesg | tail or so.

Is there anything I can do to recover this data, I stupidly did not have backed up to my OneDrive!

Thanks,

Michael

Followed those steps, still no luck.

Only using SMB shares. Removed them all and deleted all Shared Folders. Also checked that there are no Shared Folders in Use followed by a reboot.

Filesystem is still showing as Missing and Unmounted.

On top of this, I've checked in the config and found the labels that I suspect are causing the issue.

Can I remove the one with the issue, data2 was the failed filesystem?

Data1 stile works fine but I have removed the references as advised.
