Well here are my configs
You'd use a clustered filesystem if you want both nodes to be able to access the storage simultaneously. If you want to do this, you need to run drbd in dual-primary mode, and also configure DLM. If you only want the filesystem to be mounted on one node at a time, just use a regular, non clustered filesystem (ext3/4, XFS, whatever). > > node $id="609b0bcb-8904-4666-bc2c-c66b8b2b7f1e" sitasl00001 > node $id="610f86ee-6bd4-4789-8da9-9555cfa90b7b" sitasl00002 > primitive drbd ocf:linbit:drbd \ > params drbd_resource="r0" \ > op monitor interval="15s" > primitive fs ocf:heartbeat:Filesystem \ > params device="/dev/drbd0" directory="/data" fstype="ocfs2" \ > meta target-role="Started" > primitive ip ocf:heartbeat:IPaddr2 \ > params ip="10.65.68.239" nic="br0" > group cluster ip > ms ms_drbd drbd \ > meta master-max="1" master-node-max="1" clone-max="2" > clone-node-max="1" notify="true" > colocation cluster-with-drbdmaster inf: cluster ms_drbd:Master > property $id="cib-bootstrap-options" \ > stonith-enabled="false" \ > no-quorum-policy="ignore" \ > dc-version="1.0.5-3840e6b5a305ccb803d29b468556739e75532d56" \ > cluster-infrastructure="Heartbeat" \ > last-lrm-refresh="1269427049" OCFS2 needs OpenAIS for DLM to work, so you'd have to replace Heartbeat with Corosync+OpenAIS, configure DLM, etc. Check out the Clusters from Scratch documents at http://www.clusterlabs.org/wiki/Documentation for more information.
