If you need any LVM functionality you should be able to use either Sistina's LVM or IBM's EVMS. Once you have built the logical volume you want to share, you have to use iSCSI( or HyperSCSI) to make the shared volume accessible to the nodes. ==== If you are talking about shared SCSI: That cannot currently be done in a fault-tolerant way. ie. Raid 1 and 5 are not supported. If you can live with RAID 0, then I believe you can use EVMS 2.x to stripe your drives together. That is not a ogfs function, so I'm not sure. FYI: EVMS 2 includes cluster support and is ogfs compatible. OGFS gets layered above the EVMS logical volumes. There is a OGFS / EVMS howto on the docs page of the website: http://opengfs.sourceforge.net/docs.php Greg -- Greg Freemyer ------------------------------------------------------- This SF.net email is sponsored by: SF.net Giveback Program.
