I would like to note to the readers that the OCFS2 filesystem is nice in the fact that there is little configuration in setting it up but there are issues you must deal with when connectivity between systems is compromized–In a word–Fencing.

Having a back-end private network/VLAN is the probably the answer for the heartbeat connectivity between the nodes as you will most likely find out–hopefully not the hard way.

Unfortunately, I experienced fencing issues first-hand when implementing Oracle VM recently. That was an experience in itself I must say!

Thanks,
Lee

It's pretty sexy stuff, as cluster file systems go. Not a bad article, worth knowing other cluster technologies out there.

What about one on CFS (Lustre)? It’s pretty sexy stuff, as cluster file systems go.

The only variation it did not originally support was shared writeable mmap for which support was added in 2.6.23.<br /> <br /> OCFS2 1.4 has this feature and is shipping with SLES10 SP2 currently.
