[Gluster-users] Unable to peer probe between new servers and old servers

I wish I understood what's happening. What is dumped out in
/var/log/glusterfs/cli.log appears about as useful as a Windows blue screen
of death.

I'm not sure what you mean by "A pair of peers". I have two pairs that
communicate, web1 <-> web2 (old servers), and web3 <-> web4 (new servers).
When I do a "gluster peer probe" from A to B, nothing ever appears in the
log file of B; it does not matter if the peer is successful or not. I've
posted the output from cli.log from the failing "gluster peer probe" server.
