[Gluster-users] Hundreds of duplicate files

We're having the same problem --- the underlying bricks seem fine and the problem appears to be that ls is reporting the wrong thing rather than there are actually duplicate files.

We are using gluster 3.6.1-1 on machines running Scientific Linux 6.3 (we're use the glusterfs-epel packages). The underlying bricks are all ext3.

Different client machines report different duplicate files.  There doesn't seem to be pattern to why files duplicated -- some bricks seem to have more files that are listed as duplicates than others but no obvious pattern.

Some other oddities. We have a directory called dm512 that contains some duplicate files.

If I do  ls dm512, the duplicate files appear -- one of which is called restart.12

But if I say "ls restart.36", the file appears only once

But if I say "ls restart.36*", the file appears twice.  And using, find

find . -iname "restart.36" -exec echo "<{}>" \;



We upgraded from 3.5 to 3.6 about two weeks ago and user only reported the problem about a week ago. I don't think this necessarily means the problem didn't occur before -- our gluster file system is a storage area for us for relatively infrequently but important large data sets. 

It's a bit unnerving for the user and causes some scripts to break, e.g., "for x in `ls dm512`; do"
