[Gluster-users] Sent and Received peer request (Connected)

[Dj Merrill]

This morning I did a rolling update from the latest 3.7.x to 3.12.4,
with no client activity.  "Rolling" as in, shut down the Gluster
services on the first server, update, reboot, wait until up and running,
proceed to the next server.  I anticipated that a 3.12 server might not
properly talk to a 3.7 server but since I had no client activity I was
not overly concerned.

All three servers are now updated to 3.12.4.  The weirdness is that
although the third server reports a proper peer status of "Peer in
Cluster (Connected)" to both server 1 and 2, the first and second
servers report to each other "Sent and Received peer request
(Connected)" but show the proper "Peer in Cluster (Connected)" to the
third server.


[root at glusterfs1]# gluster peer status

In my notes I have a procedure for Rejected peers, which I tried:

   Stop glusterd (systemctl stop glusterd)
   In /var/lib/glusterd, delete everything except glusterd.info (the
UUID file)
   Start glusterd (systemctl start glusterd)
   Probe one of the good peers (gluster peer probe HOSTNAME), then probe
the second
   Restart glusterd, check 'gluster peer status'

This hasn't changed anything.  I've tried reboots of all servers, etc.


Any thoughts on how to correct this?

Thanks,
