Awesome, thanks!
Then, I hope this https://github.com/gluster/glusterfs/commit/ab2558a3e7a1b2de2d63a3812ab4ed58d10d8619 is included in the build.
What it means is, if you just list the xattrs of the file, you can get the file name (pgfid/basename) format. If there are no duplicate filenames, then it will be easy. Otherwise, you would need to use aux-gfid-mount to get details as told in the patch.
mount -t glusterfs -o aux-gfid-mount 127.0.0.2:testvol /mnt/aux_mount
- and then try doing the operation as told in commit message above on /mnt/aux_mount/.gfid/<gfid>
Regards,
Amar

Which is the version of GlusterFS you are using?
There are few methods like 'gfid2path' option to fetch details of the file path from a gfid in versions above v6.0

We recently were trying to track down a high load situation on a KVM
node in a cluster running gluster (replication2 + arb).
Iotop on the affected node showed that gluster was involved showing
abnormally heavy writes. There wasn't any obvious activity on the
network coming into the VMs, so it was something internal to one of
them, so we had to keep looking
We then used gluster volume top which showed that a couple of shards
were being pounded but we didn't see a way to immediately associate
those shards with their VM file.
We eventually figured out the problem VM using other methods and
resolved the issue, but we would still like to know if there is a script
or recipe to determine what file a shard may belong to as that would
have sped up the resolution.
