I recently had a raid server hang, and after a reset the 1.5TB raid 5
array no longer mounted. Being hasty, I messed around with mdadm
commands trying to find out what was going wrong, and in the process I
ran "mdadm -C" thinking that it was one of the steps for mounting an
existing array. I suspect that this was a fatal error, because now
fsck.reiserfs can't find the superblock on the array!
I had an /etc/mdadm.conf file lying around, and I happened to compare
the uuid in the /etc/mdadm.conf file and on one of the partitions.
They did not match!!!
Did I forever ruin my raid array? Is there a way to recover my
reiserfs superblock and the original array data?
Thanks,
Dave

I know how to create a new superblock for reiserfs, and rebuild the
tree, but that will only work if the data is still readable. Should I
go ahead and try this, or should I first try to reassemble my raid to
find the correct configuration?
