thanks for your reply
I can see that on the upgraded node the vols contents are different. e.g.
Node 1 (Gluster 10) cksum: info=3275244163
Node 2 (Gluster 9.3) cksum: info=1131983081
Node 3 (Gluster 9.3) cksum: info=1131983081
Comparing the checksums of the single files, I can see the following are
different in the volumes (apart from the brick info, which I suppose should
be different even on the same release):
I have also tried in a brand new cluster (just to be sure) with the same
results (i.e. peer rejected between the upgraded node and the other two on
the 9.x release)
Upgrading the other two nodes still does not resolve the issue on the first
node -- even if I bring it offline, delete the contents of the
/var/lib/glusterd directory, probe one of the other nodes and restart the
