Comment 1 Jonathan Earl Brassow 2004-10-28 15:14:36 EDT

The problem was that two inodes were pointing to the same data and
both inodes existed and were linked to from a directory.

One inode would get removed, but later, because it was detected in the
FTW, it would be readded.  When the fsck was restarted, it would
happen again.

Now, when I remove the inode, I destroy the meta header as well, so
that it is considered invalid during the FTW and does not get readded.

Steps to test:
1. uncompress attachment
2 [details]. run fsck on it
3. mount the file 'mount -t gfs <file> <location> -o loop
