[Pacemaker] problem about move node from one cluster to another cluster

[jiaju liu]

hi everybody
I use command crm openais stop first to stop openais service and then use rm -rf /var/lib/heartbear/crm/*  clear all information. then change multicast and start it in another cluster.
the problem is sometimes it works I can use crm_mon command. and sometimes it doesn't work. I use service openais status. It shows Running. but I can not use crm_mon to connect to cluster. 
I found the reason may be directory /var/lib/heartbear/crm/ is empty. why??if I reboot ,it works again.WHY
