<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>
<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>
