Hello,
I have quite a very critical problem.
One of my OSSes hanfs into a kernel panic when trying to mount the OSTs.
After mounting 11 OSTs over 12 total OSTs it goes into kernel panic.
Does not matter hte order in which they are mounted.
Any clue on hints ?
I cannot really recover it and I have important data on it.
I already performed an e2fsck. Anyway it did not fix. it has found a few
inode count inconsistencies before.
kernel is 2.6.32-431.23.3.el6_lustre.x86_64
