HI Arif, Was the conserver stopped successfully on the previous primary management node during failover? The failure with xCAT_conserver_stop_0 indicates the conserver stop fails on the previous primary management node during failover. When the conserver is running, if you manually run service conserver stop, will get any error?
Is it possible that the pacemaker configuration tries to stop conserver
more than once? when the conserver is not running, service conserver stop
will return 1.
Thanks,

Hi Li,
Let me make it clear, The conserver starts, and works without any problems,
but the crm_mon shows an error (can't really give what that is at the
moment), when failing over, then this is one of the services that then
causes the failover not to work.
The service conserver on it's own has no problems at all, and I do get exit
status to 0, this was the first thing I checked.
The error I think was on the following lines when I did "crm status"
Failed actions:
xCAT_conserver_stop_0 (node=mg01, call=21, rc=1, status=complete):
unknown error
I hope that makes sense
regards,
Arif

HI,
I was not seeing issue with conserver when I setup the HAMN with DRBD
+Pacemaker+Corosync, you mentioned conserver could not be started, if
you try to start it manually, does the command "service conserver
start" returns 0 or not? it is expected to return 0. And what is your
Pacemaker resource definition for conserver?
Thanks,

You have to also make sure that makeconservercf is run before
conserver starts up; other actions are makedhcp and restart sshd.
You have to do this after xcatd is running. We put together an
"xCAThelper" resource agent to do these for us. This has worked out
very well for us (especially when an IPoIB bug was oopsing the MN
regularly).
Hope this helps.

Hi team,
I am working on getting an image working such that I can do HA
as described in the docs.
The osimage template is almost complete, The main thing that is
missing from my setup is the conserver not working.
I have looked through the docs, and there was a mention of
conserver not being LSB compatible; I have made the relevant
changes, but still having some problems. As soon as conserver
is removed from the corosync configs, it seems all good.
I would very much like to hear your experiences, and any other
gotchas
