Just an update on this. I grabbed the system disk from the failed upgrade and had a careful look through the /var/lib/glusterd files and it looks like I might have missed changing the hostname in one of them. Seems like to change the hostname you need to grep all instances and rename a few files, I tested this theory with a spare server and it seems to work. grep -nr nas /var/lib/glusterd find /var/lib/glusterd/vols/*/bricks | grep nas I didn't change the names of the .vol files or the files in run/, but glusterd seemed to start ok, should I change these also? It's a shame the glisterd error log couldn't be a little more helpful, just saying unknown key means nothing to me. I will have to wait for another maintenance window to try again to upgrade my servers, just not sure if I can stand the stress levels!!
