Hi Lindsay,
Thanks for the info, that is good to know.
But after diagnosing for the day, I have found the relevant stuff to get it
all working,So wrt the documentation from
http://sourceforge.net/apps/mediawiki/xcat/index.php?title=Setup_HA_Mgmt_Node_With_DRBD_Pacemaker_Corosync,
the following would be the current changes, this is now successfully
working for me know. Will be doing more testing tomorrow. If the devs are
happy I will make the relevant changes to reflect the chang in rhels6.4
