The nodes are called node-0 and node-1.
It is not happening regularly. It rather happens occasionally.
Among about 50 two-node clusters we have in house I've seen this issue
in journal of 2 clusters.
I looked at logs and the pattern I see is this: stop Pacemaker and
Corosync on node-1, and then start it.
When then Corosync starts both nodes don't see each other (based on
the log messages), and they both start to complain about "Digest does
Node-1 where Corosync (and Pacemaker) was shut down and then started
again kills node-0.
Then node-0 kills node-1.
And then the cluster is successfully formed.
I didn't manage to reproduce it manually.
Also, it might be connected to network problems inside a chassis (it
turned out there might be an internal switch causing this problems).
I am investigating it now.
