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.
Hi Christine
I'll try to upgrade to latest drbd and if problem persist contact drbd
ml to debug this problem
thank you
Sorry, I can be more help, but this seems to be cause (at least nor
directly) but either corosync or cman :/
