Oops, again, sorry for the email issues, I'm having trouble getting
gmail to play right.

So now that I have a synced raid6, I'm looking at this problem of the
filesystem having been partially or fully corrupted, which happened
after a few components were ddrescued onto other components and force
assembled.  Is this something you might expect to happen in that
scenario?

mount /dev/md0 /media/vault               http://pastie.org/8042532

I do have a backup, so if it comes down to it, I can just make a new
filesystem and restore that way.  However the backup is not 100%
complete, so if possible id like to get the file system back, even
with errors, to supplement the missing part of the backup.

Is there any reason not to run "e2fsck -y /dev/md0"?

Thanks
