Is it supported throughout oVirt to use CentOS Storage SIG packages instead
of ovirt provided ones? I imagine you mean it, correct?

If this is a case, would I have to go with Gluster 3.9 (non LTS)
https://lists.centos.org/pipermail/centos-announce/2017-January/022249.html

Or Gluster 3.10 (LTS)
https://lists.centos.org/pipermail/centos-announce/2017-March/022337.html

I suppose the latter...
Any problem then with updates of oVirt itself, eg going through 4.1.2 to
4.1.3?

Thanks
Gianluca

Ok. Depending on answer related to version of Gluster to use, I will try it
In the mean time I have completed steps 1 and 2 and I'm going to read
referenced docs for reset-brick command

Thanks
