[Linux-cluster] SAN file system to be shared to multiple nodes

Hello to all,
I have some questions about setting up a shared file system for a SAN environment with multiple nodes connecting to a shared disk.

Here is what I have:

DS4000 IBM FC SAN. I have created a storage array using the IBM software. The disk is connected to by multiple systems. Basically, lets say 5 systems are connecting through a SAN FC switch to the same array.

As I discovered, the hard way, I can't just format this partition/disk ext3 as if one system writes, the other systems can't see the file until all have been unmounted and remounted again. So I need to have a shared file system that used by all the nodes that will allow reads/writes to be recognized by all the systems connecting to the shared SAN array.

So my question is, what is the best file system available that is production worthy and capable of running on a Slackware 10.2 distro. Naturally, I would guess a lot of people would say GFS or OpenGFS, however is it stable and production ready. What about other shared file systems such as InterMezzo or Coda?

Any suggestions would be greatly appreciated.
