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. Regards, Bob Peterson Red Hat Cluster Suite
What good is mounting the ext3 filesystem read-only on all but one node? Suppose node A is the node that mounts the filesystem read-write, and node B a node that mounts it read-only. B reads a file from the filesystem, which gets cached on node B. Node A changes that same file. How is node B to know that the data it cached is out of date?
