Only problem I would like to manage is that I have gluster network shared with ovirtmgmt one.
Can I move it now with these updated packages?

Are the gluster peers configured with the same hostnames/IPs as your hosts within oVirt?

Once they're configured on the same network, separating them might be a bit difficult. Also, the last time I looked, oVirt still doesn't support managing HCI oVirt/Gluster nodes running each service on a different interface (see below).

In theory, the procedure would involve stopping all of the Gluster processes on all of the peers, updating the peer addresses in the gluster configs on all of the nodes, then restarting glusterd & the bricks. I've not tested this however, and it's not a "supported" procedure. I've no idea how oVirt would deal with these changes either.

Which version of glusterfs do you have running now? With glusterfs>= 3.9, there's a reset-brick command that can help you do this.

At this moment on my oVirt nodes I have gluster packages as provided by 4.1.2 repos, so:

glusterfs-3.8.13-1.el7.x86_64
glusterfs-api-3.8.13-1.el7.x86_64
glusterfs-cli-3.8.13-1.el7.x86_64
glusterfs-client-xlators-3.8.13-1.el7.x86_64
glusterfs-fuse-3.8.13-1.el7.x86_64
glusterfs-geo-replication-3.8.13-1.el7.x86_64
glusterfs-libs-3.8.13-1.el7.x86_64
glusterfs-server-3.8.13-1.el7.x86_64
vdsm-gluster-4.19.15-1.el7.centos.noarch

Is 3.9 version of Gluster packages provided when updating to upcoming 4.1.3, perhaps?

No, it's not. One option is to update glusterfs packages to 3.10.

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

There's an RFE open to add this to GUI. For now, this has to be done from command line of one of the gluster nodes.

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
