Hi,
really don't know if it's relevant in your situation, but I was once
stuck with such a situation on a raid1 system (which worked correctly
for a while). Turned out that the filesystem size was incorrect, and was
overlapping with the superblocks (don't know how it happened, must have
been at the raid creation time).
I ran a e2fsck -cc (from a live-cd, takes a while), then resize2fs and
finally fsck on every raid group.
It does the trick, and the system has been running fine ever since (was
± one year ago.)
Hope it helps,
Tom
