Filesystem status after disconnecting drive

Last night my modem was misbehaving so I disconnected by budget NAS setup (OMV with raspberrypi) and tried to connect the hard drive directly to a laptop and then another raspberry pi to see if I could access the media files and watch something. When I reconnected the hard drive to my NAS setup the filesystem has shown up as missing in the OMV.

The system log shows this recurring message:

Is there anything I can do to restore the filesystem?

May I ask why you try to find an answer for OMV from the OSMC forum?

Well first question is what filesystem was on the disk before?
Maybe start with output of lsblk -f

Sorry wrong forum, just woke up
