Re-reading it I was wrong it does seem to be some sort of network filesystem, the way they phrase: What is GFS? The Global File System (GFS) allows multiple Linux machine to share storage devices over a network. Each machine sees the network disks as local, and GFS itself appears as a local file system. Writes to a file by one Linux machine are seen by another machine that later reads that file. Looked like a vn device over NFS except using some special protocol instead of NFS, basically only one client can see a filesystem at a time. -- -Alfred Perlstein - [bright@wintelcom.net|alfred@freebsd.org] "I have the heart of a child; I keep it in a jar on my desk."
