There are various fonnats supported for clustered systems, including AFS and GFS2. In general, they are not used for the basic system files required for booting, but are better suited for shared data. It is possible to set up such systems for booting, but this is beyond the scope of this discussion. Ifyou are interested, there are a number of publications available on Linux clustering. A good starting point might be the Wikipedia article on clustered filesystems at http:/len. wikipedia.org/wikil Clustered_file_system.
