Gluster users - Jun 2016 - 3.7.12 disaster

Was able to shutdown my gluster and clean reboot.

set:

cluster.shd-max-threads:4
cluster.locking-scheme:granular

And started one VM. It got halfway booted and froze. A gluster heal
info returned "Not able to fetch volfile from glusterd"

I killed the VM, stopped the datastore and all gluster processes, then
started it back up. Heal info was successful and showed 200+ shards
being healed.

however a heal info heal-count show's 0 heals

I stopped the dtastore again and reset the settings:
  cluster.shd-max-threads
  cluster.locking-scheme

Waiting for heal to complete. Before I try again.

Contemplating undoing the upgrade. Can I set the opversion back to 30710?

Same problem again. VM froze and heal info timed out with "Not able to
fetch volfile from glusterd". I'm going to have to revert to 3.7.11

So you had no problems before setting that ? I'm currently re-installing my
test
servers, as you can imagine really really hoping 3.7.12 fixes the corruption
problem,
I hope there isn't a new horrible bug ..

Just to add some info on that, I did a fresh install of 3.7.12 here (without
setting that option)
and I don't have a problem starting the VMs.

I do have a problem the libgfapi though, I can't create VMs with qcow disks
(I get a timeout)
and I can create VMs with raw disks but when I try to format them with mkfs.ext4
they shut down
without any errors.
Maybe it's related ? Are you using qcow ?
I added the volume as NFS and I'm using that without any problem for now
with both qwoc and raw, maybe
you could try that, see if at least your VMs can boot that way.
