It fails at first step:

 [root at ovirt01 ~]# gluster volume reset-brick export
ovirt01.localdomain.local:/gluster/brick3/export start
volume reset-brick: failed: Cannot execute command. The cluster is
operating at version 30712. reset-brick command reset-brick start is
unavailable in this version.
[root at ovirt01 ~]#

It seems somehow in relation with this upgrade not of the commercial
solution Red Hat Gluster Storage
https://access.redhat.com/documentation/en-US/Red_Hat_Storage/3.1/html/Installation_Guide/chap-Upgrading_Red_Hat_Storage.html

So ti seems I have to run some command of type:

gluster volume set all cluster.op-version XXXXX

with XXXXX > 30712

It seems that latest version of commercial Red Hat Gluster Storage is 3.1
and its op-version is indeed 30712..

So the question is which particular op-version I have to set and if the
command can be set online without generating disruption....

Thanks,
Gianluca
