We just run NFS3, mostly for legacy reasons, I haven't really investigated NFS4, but I like what I've heard. Most user directories are mounted sync, it seems to me like the only safe way. There are some size adjustments also, but I've forgotten what they are or what motivated them. The NFS performance HOWTO is useful for setting these things. -- A. -- Andrew Reid / [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
