I tried to add another drive to an external eSATA box connected to my OMV server.
The disks in the system are
/dev/sda
/dev/sdb
/dev/sdc
/dev/sdd
/dev/sde
/dev/sdf
/dev/sdd is the boot drive. a, b, c, and e are all physically inside the case, sata devices connected to motherboard. /def/sdf is in an external eSATA enclosure. "f" is a 4 terabyte drive, so prior to adding this drive, the total was ~10 terabytes: 3 x 2 TB + 1 x 4 TB.
I had configured the Logical Volume to include "f" that was in the enclosure.
I acquired a second 4 TB drive and tried to get it set by inserting it into the enclosure, after powering down the enclosure but without powering down the entire OMV server.
I had added it to the logical volume, but not used the "extend" function to actually add it. the drive was in the volume, but the size of the volume still only showed as if it wasn't added. This may be irrelevant, as just meant that despite adding the new 4 terabyte drive, the logical volume was still only 10 terabyte.
Long story short, the folder
/media/{guid}/
is now empty... none of the mount points that were there:
video
documents
software
music
backups
are there any more... but I am confident I didn't format / erase the drives or anything.
Is there any way via command line to confirm that there is actually still data there?
then, if the data is all still there, is there any way to recover the mount points etc.?
I have been googling for half an hour and my grasp of linux terminology isn't great, so maybe I'm not searching for the right things... "fdisk -l" gives me this: (I admit with some command line tools, it gives me strange values like "partition table: unknown"... but again it was all working until... i messed something up... and now I have to try to recover... things... somehow.

Thanks terribly much in advance.
