Hi Stefano,
thanks for the great input!
I went over the logs (is the screencast uses the same domains? i don't have the logs
from that run) - the master domain deactivation (and the master role migration to the new
domain) fails with the error to copy the master fs content to the new domain on tar copy
(see on [1] the error).
1. Is there a chance that there is any problem inconsistent storage access problem to any
of the domains?
2. Does the issue reproduces always or only in some of the runs?
3. Have you tried to run a operation that creates a task? a creation of a disk for
example.
thanks,
Liron.

Subject: Re: [ovirt-users] Sync Error on Master Domain after adding a second one
I think I finally managed to replicate the problem:
1. deploy a datacenter with a virt only cluster and a gluster only cluster
2. create a first GlusterFS Storage Domain (e.g. DATA) and activate it
(should become Master)
3. create a second GlusterFS Storage Domain (e.g. DATA_NEW) and activate it
4. put DATA in maintenance
Both Storage Domains flows between the following states:
https://www.dropbox.com/s/x542q1epf40ar5p/Screencast%20from%2027-02-2015%...
Webadmin Events shows: "Sync Error on Master Domain between Host v10 and
oVirt Engine. Domain: DATA is marked as Master in oVirt Engine database but
not on the Storage side. Please consult with Support on how to fix this
issue."
It seems DATA can be deactivated at the second attempt.
