[Gluster-users] Removing orphaned hard links under .glusterfs

[Andrew Zenk]

I would think that the link count should be sufficient.  I've attached a
python module that we've used to do some brick level indexing and cleanup
on our system.  You could use it to generate a list of the .glusterfs links
for the remaining good files on the disk.  Then you could check your
candidates for removal against the list before removing them.
