Whoops, scratch that last post. I now have it working by leaving the entry in fstab without the noauto and turning GFS off with chkconfig and allowing the cluster service to turn it on.

Thanks a million, I didn't realize that GFS needed a fstab entry with a noauto entry to get it to work. --- Chris Edwards Smartech Corp.

Should it automatically mount > my GFS file system? there is a GFS service. If you set it to autostart, it will mount any gfs file systems defined in /etc/fstab. 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.
