While verifying I got this error, crm_verify -L -V error: unpack_resources: Resource start-up disabled since no STONITH resources have been defined error: unpack_resources: Either configure some or disable STONITH with the stonith-enabled option error: unpack_resources: NOTE: Clusters with shared data need STONITH to ensure data integrity
Looks like stonith has to be configured. Also to do that I don't have CRM application. I think I have to install from here "wget -P /etc/yum.repos.d/ http://download.opensuse.org/repositories/network:/ha-clustering/CentOS_CentOS-6/network:ha-clustering.repo"; and then #yum install crmsh.x86_64 But it didn't worked for me. I stuck in here with this stonith.
