I've run into a similar problem when using VDO + LVM + XFS stacks, also
with ZFS.
If you're trying to use ZFS on 4.4, my recommendation is don't. You have
to run the testing branch at minimum, and quiet a few things just don't
work.
As for VDO, i ran into this issue when using VDO and a NVME for LVM
caching of the thin pool, VDO would throw a fit and under high load
scenario, VM's would regularly pause.
VDO with no cache was fine however, seems to be related to mixing device
types / block sizes (even if you override block sizes).
Not sure if that helps.

Maybe the shard xlator cannot cope with the speed of the shard creation speed.
Are you using preallocated disks on the Zimbra VM ?

Hello,
running ovirt 4.4.4.7-1.el8 and gluster 8.3.
When i performe a restore of Zimbra Collaboration Email with features.shard on, the VM pauses with an unknown storage error.
When I performe a restore of Zimbra Collaboration Email with features.shard off, it fills all the gluster storage domain disks.
With older versions of gluster and ovirt the same happens. If I use a NFS storage domain it runs OK.
