You will also need a filesystem that supports shared storage. Sistina's Global File System (GFS) is the only such filesystem available for Linux, afaik (at only $995 per node; shared storage is NOT easy to implement). If you do not have such a filesystem, you will most likely completely trash your filesystem when you mount it from the 2nd machine. iSCSI/FibreChannel is not NFS. It is block-level access to raw storage just like SCSI or IDE. -- Dan Nelson [EMAIL PROTECTED] -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of "unsubscribe". Trouble?
