Apologies for double post. In my initial post, I forgot to set the subject properly.
Hello List, I am new here. I worked with Linux HA during 2006-2008, went in HPC direction, and came back to HA a month ago. Realized that a lot has changed. My setup: Two KVM machines vdb1 (192.168.122.11), vdb2 (192.168.122.12) ClusterIP: 192.168.122.10 Fedora 19 (64 bit). PCS, CoroSync, PaceMaker, DRBD Note: I use the names node1 and node2 for vdb1 and vdb2 for explanations. I am trying to setup a test cluster, using http://clusterlabs.org/doc/en-US/Pacemaker/1.1-pcs/html/Clusters_from_Scratch/_configure_the_cluster_for_drbd.html First, the status: [root@vdb1 drbd.d]# pcs status Cluster name: MySQLCluster Last updated: Tue Nov 26 14:05:33 2013 Last change: Mon Nov 25 17:25:59 2013 via crm_resource on vdb2.example.com Stack: corosync Current DC: vdb1.example.com (1) - partition with quorum Version: 1.1.9-3.fc19-781a388 2 Nodes configured, unknown expected votes 2 Resources configured.

(i.e. by using an intermediate config file). But my question is, why I cannot use the two commands individually? Are there any limitations in doing so? If someone can explain the above errors and the reasons behind them, I would really appreciate. Thank you for your time.
