[Gluster-users] Unable to add brick from new fresh installed server into upgraded cluster

[Alastair Neil]

I have a 2 server CentOS 6 replicated cluster which started out as version
3.3 and has been progressively updated  and is now on version 3.6.1.
Yesterday I added a new freshly installed CentOS 6.6 host and wanted to
convert to replica 3 on one of my volumes, however I was unable to add the
brick as it reported that all the brick hosts had to be at version 03060.
Presumable some minimum compatibility is set on the volume, but I am
struggling to find where.  The info file under
/va/lib/glusterd/vols/volname has op-version=2, client-op-version=2.

Any suggestions?


Thanks, Alastair
