Gluster users - Nov 2018 - VMs paused - unknown storage error - Stale file handle - distribute 2 - replica 3 volume with sharding

Hi,
I opened a bug on gluster because I have reading errors on files on a 
gluster volume:
https://bugzilla.redhat.com/show_bug.cgi?id=1652548

The files are many of the VMs images of the oVirt DATA storage domain. 
oVirt pause the vms because unknown storage errors.
It's impossibile to copy/clone, manage some snapshots of these vms. The 
errors on the low level are "stale file handle".
Volume is distribute 2 replicate 3 with sharding.

Should I open a bug also on oVirt?

Gluster 3.12.15-1.el7
oVirt 4.2.6.4-1.el7

Regards,

Thanks, this bug should do. I've requested for info on the bug - could
you update it?

Hi,
is there a way to recover file from "Stale file handle" errors?

Here some of the tests we have done:

- compared the extended attributes of all of the three replicas of the 
involved shard. Found identical attributes.

- compared SHA512 message digest of all of the three replicas of the 
involved shard. Found identical digests.

- tried to delete the shard from a replica set, one at a time, along 
with its hard link. Shard is always rebuilt correctly but error from 
client persists.
