Hi again,
I went ahead and upgraded the last two nodes in the cluster.
This is what I noted:
I upgraded the arbiter first and in:
/var/lib/glusterd/vols/gds-common/info
The parameter "nfs.disable=on" was added by the upgrade and
made the checksum fail.
I removed "nfs.disable=on" and all the three nodes connected fine.
I upgraded one of the other nodes and no changes were made to
the /var/lib/glusterd/vols/gds-common/info file, so the arbiter
node and the resent upgraded node had contact.
I upgraded the last node and on this node the parameter "nfs.disable=on"
was added in file: /var/lib/glusterd/vols/gds-common/info
I removed "nfs.disable=on" and restarted glusterd and the entire cluster
is up and ruunning the way it should.
The command: gluster volume get all cluster.max-op-version
Still says:
Option Value
------ -----
cluster.max-op-version 100000
I hope that this info helps!
Please let me know if I can help out in any other way!
Regards
Marcus

One of the servers has the value "nfs.disable=on" but the others do not. This can be the difference that causes the checksum error.
