Hi Team, In our product we have 9 nodes pacemaker cluster setup non-DC nodes reboot parallelly. Most of nodes join cluster properly and only one node pacemaker and corosync service is not came up properly with below error message.
Error Message: Error: error running crm_mon, is pacemaker running? crm_mon: Connection to cluster failed: Connection refused Query : Is it recommended to reboot parallelly of non-DC nodes ? Thanks and Regards, S Sathish S
