Hi Alessandro
Thanks for those. I can see that CMAN was told by some external program
to send that KILL to node 2 from this line here:
daemon: client command is 8000000c
It's not clear what might be asking cman to do this. A common culprit is
qdisk, but I can't see any qdisk in your cluster.conf or log files so it
must be something else. I'm don't think pacemaker does anything like that.
I can see you have pacemaker-managed drbd on the system so that might be
worth investigating - I can't see any actual drbd messages in those log
files so they might be elsewhere.
Sorry, I can be more help, but this seems to be cause (at least nor
directly) but either corosync or cman :/
