Hi David,

As long as the ext3 file system is mounted read only by all but one 
node, you should be able to do this.
However, if you need read/write capabilities on both file systems on the 
SAN, then ext3
will just get you in trouble.  Since ext3 isn't cluster aware, the nodes 
will walk all over each other's data.
That's what GFS was designed to prevent.
