After this I tried again to move the disk, and surprise, successfully
I didn't believe it.
Try to move another disk, the same error came back

Usually distributed volumes are supported on a Single-node setup, but it shouldn't be
the problem.
As you know the affected VMs , you can easily find the disks of a VM.
Then try to read the VM's disk:
sudo -u vdsm dd
if=/rhev/data-center/mnt/glusterSD/gfs1.server.pt:_gfs1data/<Storage_domain_UUID>/images/<DISK-UUID>/<VM_DISK>
of=/dev/null bs=4M status=progress
Does it give errors ?

I should admit I have never seen this type of error.
Is it happening for all VMs or only specific ones ?

I can move a disk from gluster2 to gluster1, but cannot move the same disk from gluster1
to gluster2

No, but keep an eye on you "/var/log" as debug is providing a lot of info.
Usually when you got a failure to move the disk, you can disable and check the logs.

You still haven't provided debug logs from the Gluster Bricks.
There will be always a chance that a bug hits you ... no matter OS and tech. What matters
- is how you debug and overcome that bug.
Check the gluster brick debug logs and you can test if the issue happens with an older
version.
Also, consider providing oVirt version, Gluster version and some details about your setup
- otherwise helping you is almost impossible.

For smaller installations, without the need of storage HA, maybe it's better to use
NFS? Is more stable?

I can recommend you to:
- enable debug level of gluster's bricks
- try to reproduce the issue
I had similar issue with gluster v6.6 and above.

I tried to move the VM disk with the VM up
I also tried to move or copy the disk with the VM down, and get the same error.
Strange is, I have a gluster storage domain, with an older gluster version, that worked. I
was able to move the disk to this older gluster and also I was able to copy the disk from
to this older gluster storage
What should I do with this VM? Should I shut it down and try delete the snapshot?
Regards
José

Hi,
I was trying to move a disk between glusters domain storage without success.
# gluster --version glusterfs 6.10
Now have a VM with this message:
The VM has snapshot(s) with disk(s) in illegal status. Please don't shutdown the VM
before successfully retrying the snapshot delete
oVirt verison is
Version 4.3.10.4-1.el7
I cannot delete the snapshot. What should I do?
