Not sure what you mean by a partition table crash. Is it that someone
overwrote the partition table on the iscsi server? That's what it looks
like. If mount cannot detect the fs type, then it means atleast superblock
corruption. And such corruptions typically caused by external entities.

Given it was under heavy usage because of many VM running on, I guess this may
be the cause. now I am trying to recover it

current-sighand is NULL. So definitely a race. Generic kernel issue.

I am unclear. What happens when a server is rebooted (or crashes).
Crash the network? Can you expand on this?

I'll look at the tunefs issue. But the other one does not make sense.
strict_jbd is a compat flag. Mount should work. What is the mount
