Very good. Does it show the data/filesystems you are expecting?
If you are certain that they are not is use elsewhere, can you mount them?
If you are not sure, think carefully. Trying to mount them may just refuse, but it may possible say "Are you sure?" and then force it or just try and fails with a suggestion to fsck it. All of these could be very bad for your data. When sharing a LUN/filesystem(s) between servers, there is usually a need for good HA software. There are all sorts of problems, such as the free block list which will be held in memory, so if one side uses some free blocks, the other side doesn't know about it and could just use the same blocks causing data loss.
Kind regards,
Robin
