Re: [Pacemaker] [Question] About quorum-policy=freeze and promote.
Hi Andrew, Okay. I wish this problem is revised by the next release. crm_report? I confirmed a problem again in PM1.2-rc1 and registered in Bugzilla. * http://bugs.clusterlabs.org/show_bug.cgi?id=5212 Towards Bugzilla, I attached the crm_report file.

Hi Emmanuel, Why are you using ssh as stonith? i don't think the fencing is working because your nodes are in unclean state No, STONITH is not carried out because all nodes lose quorum. This is right movement of Pacemaker. It is an example to use STONITH of ssh.
