I am running e2fsck on one of my OSTs.
I run into:
File /O/0/d6/768742 (inode #22479589, mod time Fri Aug 17 11:15:51 2012)
  has 1034 multiply-claimed block(s), shared with 4 file(s):
        ... (inode #25579161, mod time Wed Oct  6 20:47:34 2010)
        ... (inode #25579148, mod time Wed Oct  6 20:47:28 2010)
        ... (inode #25579135, mod time Wed Oct  6 20:47:12 2010)
        ... (inode #25579134, mod time Wed Oct  6 20:47:10 2010)

It seems to imply there are only a few files affected by this issue.
I would like to hunt down the specific file and delete/restore it, but how do I identify it?
The OST is 16TB and the lustre filesystem itself is about 80TB

I do have the OST offline and unmounted.
Is there a quick/simple way to find the affected file(s)
