The gluster storage domain, now is a mess, I cannot run a VM, always get this 
error: 
VM webmail.domain.pt-3 is down with error. Exit message: Unable to set XATTR 
trusted.libvirt.security.selinux on 
/rhev/data-center/mnt/glusterSD/gs1.domain.pt:_data1/d680d289-bcaa-46f2-b464-4d06d37ec1d3/images/5167f58d-68c9-475f-8b88-f278b7d4ef65/9b34eff0-c9a4-48e1-8ea7-87ad66a8736c:
 No space left on device. 

I had a second brick and have 1.5TB free, I don't know why it says "No space 
left on device" 

Also, I cannot use the iso files I have in this storage domain. 

Regards 
José

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.
