I agree -> fencing is mandatory.
Agreed that with proper fencing setup the cluster wouldn'thave run
into that state.
But still it might be interesting to find out what has happened.
Thank you for looking past the fencing issue to the real question.
Regardless of whether or not fencing was enabled, there should still be some
indication of what actions the cluster took and why, but it appears that
cluster services just terminated silently.
Not seeing anything in the log snippet either.
Me neither.
Assuming you are running something systemd-based. Centos 7.
Yes. CentOS Linux release 7.5.1804.
Did you check the journal for pacemaker to see what systemd is thinking?
With the standard unit-file systemd should observe pacemakerd and
restart it if it goes away ungracefully.
The only log entry showing Pacemaker startup that I found in any of the
messages files (current and several days of history) was the one when I
started the cluster manually (see below).
Guess if systemd finding out about a stopped service is logged
to any file is configuration dependent.
Was more thinking of 'systemctl status pacemaker' or
'journalctl -u pacemaker'.
If cluster processes stopped or crashed you obviously won't see any logs
from them until they are restarted. You need to look at other system logs -
may be they record something unusual around this time? Any crash dumps?
The messages log shows continued entries for various pacemaker components, as
mentioned in a previous email. Could not find any crash dumps.
