"dpkg -l <package>" would also tell you what versions you have
installed, in a more concise fashion.

Yep, no surprise here.

OK. Whether this is related to your original problem or not a complete
open question, jftr.

Pacemakerd seems to exit, but fail to notify the other nodes of its shutdown. Syslog is flooded with "Retransmit List" messages (log attached). These persist until I stop corosync. Asked immediately after stopping pacemaker and corosync on one node, "crm status" other nodes will report that node as still online. After a while, the stopped node switches to offline; I assume some timeout is expiring and they are assuming it crashed.

You didn't give much other information, so I'm asking this on a hunch:
does your pacemaker service configuration stanza for corosync (either
in /etc/corosync/corosync.conf or in
/etc/corosync/service.d/pacemaker) say "ver: 0" or "ver: 1"?

Cheers,
Florian
