hi Anthony,
Could you send the output of the getfattr -d -m . -e hex
<filepath> on both the bricks and also the stat output on the both the
backends. Give the outputs for its parent directory also.

I was wondering if anyone would be able to shed some light on how a
file could end up with inconsistent md5sums on Gluster backend storage.
Our configuration is running on Gluster v3.1.5 in a
distribute-replicate setup consisting of 8 bricks.
Our OS is Red Hat 5.6 x86_64.Backend storage is an ext3 RAID 5.
The 8 bricks are in RR DNS and are mounted for reading/writing via NFS
automounts.
When comparing md5sums of the file from two different NFS clients,
they were different.
The extended attributes of the files on backend storage are
identical.The file size and permissions are identical.The stat data
(excluding inode on backend storage file system) is identical.
However, running md5sum on the two files, results in two different
md5sums.
Copying both files to another location/server and running the md5sum
also results in no change – they’re still different.
Gluster logs do not show anything related to the filename in
question.Triggering a self-healing operation didn’t seem to do
anything and it may have to do with the fact that the extended
attributes are identical.
If more information is required, let me know and I will try to
accommodate.
Thank you
