HI Arif, Oh, I was not aware that you are using Ubuntu. The conserver patch on RHEL/SLES might not work on Ubuntu, thanks for the patch below, will have the xCAT Ubuntu developer to integrate the code changes into xCAT.
The xCAT HAMN doc http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Setup_HA_Mgmt_Node_With_DRBD_Pacemaker_Corosync was only tested on RHEL, is there any documentation update needed for HAMN on Ubuntu?

(Does it take a while to start, or to start, or to do a status, if you run the script manually? Your timeouts need to reflect this.) You are starting it up after xcatd is started? (I have a resource group with xcatd, my xcathelper script resource, dhcpd, conserver, and httpd, so that everything is treated as a group, colocated, and ordered. The resource group colocates after an HA-IP address is started.)

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 On 22/05/13 01:44, Guang Cheng Li wrote: 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.

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. /Lindsay On Mon, May 20, 2013 at 2:27 PM, Arif Ali <m...@arif-ali.co.uk> wrote: 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.
