but which qcow2/FVM file choose for deletion? maybe there is
some known current best-practice for the VM maximum stability<br>
<br>
if the VM is frozen the decision maybe to delete the oldest
qcow2/FVM file, or random choose if there is no difference<br>
<br>

Right after Joe Julian released a pretty handy system for
exploring the split brains and fixing. You can check it out

<div>hello Bryan and thanks for sharing!<br>
<br>
how did you fix those 2 files on a split-brain
situation? deleted one "bad" file?

<br>
on an software update situation I would expect not
to have peer probe problems, simply because there
are no "gluster peer probe" commands. The problem
that could happen is the updated 3.4.2 node having
problems reentering a 3.3.0 cluster (without
"peer probes" commands). It's good news it went
well<br>

<div>I just did this last week from
3.3.0->3.4.2.<br>
<br>
I never got the peer probe problems - but I did
end up with 2 files being in a split-brain
situation.<br>
<br>
</div>
Note: I only had ~hundred files that are qcow2 for
KVM, so 2 files getting split-brain is about 2%
filesystem problem.<br>

<br>
anyone tried a rolling upgrades with no
downtime [1] from 3.3.0 to 3.4.2 or similar
upgrade? any comments?<br>
<br>
for testing purposes we've installed a 3.4.2
server and it won't peer, giving the error
"peer probe: failed: Peer X does not support
required op-version".<br>
<br>
I guess this is expected behavior for a new
entry on the cluster<br>
<br>
What about changing the software on an
existing peer of the cluster? Will it also
refuse to re-enter the cluster after the
upgrade for the same reason (peers not
supporting the required op-version)?<br>
<br>
After all servers and clients are upgraded,
how to increase the op-version of the global
cluster?<br>
<br>
