I did just this and it looks like the memory is shot so on one of the nodes
so I'm doing all the work on the other node..... thanks for the pointers!

Hi, Hiren,

I agree with Christian, before running fsck, you should have a look on the
hardware status. If it's not a file system issue, running fsck may cause
terrible amount of files lost.
Additionally, you need to create a backup with the help of dd before any
fsck, so that you are able to recover some lost files.

Good luck,

Is there any chance that some other node on the san has this lun
mounted, or is writing to it?
