Eventually I can destroy and recreate this "export" volume again with the old names (ovirt0N.localdomain.local) if you give me the sequence of commands, then enable debug and retry the reset-brick command

So it seems I was able to destroy and re-create.
Now I see that the volume creation uses by default the new ip, so I reverted the hostnames roles in the commands after putting glusterd in debug mode on the host where I execute the reset-brick command (do I have to set debug for the the nodes too?)

You have to set the log level to debug for glusterd instance where the commit fails and share the glusterd log of that particular node.
 


[root@ovirt01 ~]# gluster volume reset-brick export gl01.localdomain.local:/gluster/brick3/export start
volume reset-brick: success: reset-brick start operation successful

[root@ovirt01 ~]# gluster volume reset-brick export gl01.localdomain.local:/gluster/brick3/export ovirt01.localdomain.local:/gluster/brick3/export commit force
volume reset-brick: failed: Commit failed on ovirt02.localdomain.local. Please check log file for details.

See here the glusterd.log in zip format:
https://drive.google.com/file/d/0BwoPbcrMv8mvYmlRLUgyV0pFN0k/view?usp=sharing

Time of the reset-brick operation in logfile is 2017-07-06 11:42
(BTW: can I have time in log not in UTC format, as I'm using CEST date in my system?)

I see a difference, because the brick doesn't seems isolated as before...

And also in oVirt I see all 3 bricks online....
