This is kind of tangent and probably not at all what you want to use, but I'll throw it in to the discussion. On our cluster we've been playing with NBD (network block device) which basically makes a regular file or block device (partition) on machine1 look like a block device on machine2. For our setup this looks like: machine1:/dev/nd0 == machine2:/dev/hda5 Of course this just skips the whole NFS thing. The kernel module is under unsupported in the fedora kernels at least. I don't know about 2.6 or vanilla 2.4. You have to get the client and server programs here: http://nbd.sourceforge.net/ and making them use large file support is a bit tricky, but it works! The client/server programs really need some more development in the disconnect handling area. Like I said, it's probably not what you want, but it's an interesting concept. -- Timothy A.
