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] --------------------------------------------------------------------- Before posting, please check: http://www.mysql.com/manual.php (the manual) http://lists.mysql.com/ (the list archive) To request this thread, e-mail <[EMAIL PROTECTED]> To unsubscribe, e-mail <[EMAIL PROTECTED]> Trouble unsubscribing?
