The trouble is, ext2 doesn't work right now _either_ for multiple nodes
accessing the same disk. You'd be much better off helping with GFS, as
it was designed from the ground up to support shared disks.
There are fundamental obstacles to using ext2 on shared devices. For
example, we have completely idependent data structures, such as the
group descriptors and inodes, which share a single block on disk.
That's fine for a single accessor, but on a shared disk it makes it
impossible to modify those data structures atomically without locking
data which might be in use on other nodes too.
Really, ext2 is just not designed for shared-disk usage. GFS is.
