On Linux, you can put the client cache on ext2 or ext3.  Nothing else.
You definitely cannot use XFS.

On IRIX, you can use XFS for the client cache.  IRIX is a different
issue.

On Solaris, you can put the cache on a file system with logging, but if
you do, you should make it a separate partition.

For the *server*, you can run the namei file server on pretty much any
file system.  The inode file server may be more sensitive; I'm not sure.

I don't think that's an issue any more.
