VMs paused - unknown storage error - Stale file handle - distribute 2 - replica 3 volume with sharding
6:19 a.m.
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?

New subject: [Gluster-users] VMs paused - unknown storage error - Stale file handle - distribute 2 - replica 3 volume with sharding
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.

Hi Marco,
It looks like I'm suffering form the same issue, see;
https://lists.gluster.org/pipermail/gluster-users/2019-January/035602.html
I've included a simple github gist there, which you can run on the machines with the
stale shards.
However i haven't tested the full purge, it works well on individual files/shards.
Best Olaf
