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

[rturnbull]

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.
