To solve problem 2, simply disable corosync/pacemaker from starting on

so you can ssh into it and look at what happened. It won't try to rejoin

For a really silly idea, but can you swap the network cards for a test?
Say, with Intel NICs, or even another Broadcom model?
Unfortunately no: The 4-way NIC is onboard, and all slots are full.
Too bad.

As for multi-DC support, watch the booth project. It's supposed to bring

Stretch clustering is already possible and supported (depending on whom
you ask; it is on SLE HA) with corosync.
