> What is CXFS ?
CXFS is a cluster version of XFS - using fiber channel disks, multiple
machines can have direct access to the filesystem. User data is transferred
direct between the disk and buffer cache / user memory on each host,
meta-data changes are performed on a designated server node. Data
coherency is managed between machines via a token passing protocol.
CXFS supports server failover and relocation - should the server crash
a client node takes over as the server - all the other clients are
redirected to the new server, you can also administratively move the
server. All of which can be done without stopping processes using the
filesystem.
It is currently only available for Irix, it is planned to port it to
Linux, but it is not clear if it will be open source or not. SGI's
external website seems not to say much about it...

Good question - I tend to just use the code, but someone must
have a reference.
