Hi, i have some problems with our DLM, so i wanted to trace it. Yesterday i just set a trace for "monitor". No restart of DLM afterwards. It went fine as expected. I got logs in /var/lib/heartbeat/trace_ra. After some monitor i stopped tracing.
Today i set a trace for all operations.
Now resource DLM restarted:
* Restart dlm:0 ( ha-idg-1 ) due to
resource definition change
I didn't expect that so i had some trouble.
Is the difference in this behaviour intentional ? If yes, why ? Is there a rule
?
Furthermore i'd like to ask where i can find more information about DLM,
because it is a mystery for me.
Sometimes the DLM does not respond to the "monitor", so it needs to be
restarted, and therefore all depending resources (which is a lot).
This happens under some load (although not completely overwhelmed).
Thanks.
Bernd
