You would have to set up iSCSI first, and have your volumes accessible - to GFS, these just block devices, regardless of the underlying technology - DRBD / iSCSI / SAN. The order of startup should be iSCSI first, then cluster services (cman, locking service such as DLM, fencing, etc) from the cman service and once the cluster services are up, you can then mount gfs file systems, via "service gfs start". Also look into using a quorum disk in your cluster, it can help with the cluster maintaining quorum when a few nodes go down. Here is a sample gfs entry from my fs tab. /dev/sda1 /gfs/cache1 gfs num_glockd=6,noatime,noquota,nodiratime 0 0 You would replace /dev/sda1 with the path to your iSCSI device.
