Thanks for your reply.

So the way I understand is that it can be upgraded but with a downtime, 
which means that there are no clients writing to this gluster volume, as 
the volume is stopped.

But post a upgrade we will still have the data on the gluster volume 
that we had before the upgrade(but with downtime).
