I recently tried to add extra storage to my Raspberry Pi running OMV.
I powered off the machine before removing an existing drive and replacing it with a new one.
Ever since turning the machine back on, my existing drives are no longer present in OMV.
The only Disk showing under Storage is the memory card, onto which OMV is installed.
I previously had two external drives, which are now showing as 'Missing' under File Systems.
How do I get them back?
I am happy to provide any further information that is requested.
