Hello Ryan, If you want to have shared storage by two nodes via a SAN, you should look for a clustered filesystem like gfs2 or ocfs2. We use shared storage by replication via glusterfs (www.gluster.org). The backend storage can be on a LUN or on a local disk. If one node fails, the standby has a replicated data set on which he will operate.
Works very nice. regards, Richard >Hi, > >My testing two node (openais and corosync) cluster is up and running (RHEL >v5.5).
