You have a very big gun in your hands and it is pointing towards your foot. This gives both sides simultaneous R/W access to the disk. I don't think you want to do this. You have no protection at all from typo's in your directory entries. If you really want to have a pool of disks among your VM systems, I would suggest you pick a scheme to identify which VM system 'owns' the volume and only attach those to SYSTEM per your system configuration file. Then replace the DEDICATE by (full pack) mini disks. As I said: if this is just one or a few disks that you want to use on both sides, provide a copy to each system. You could even DDR them over after a change if that works better than file level replication with rsynch or so. > Should I need to 1000 DASD is format with journalled > filesystems(=ext3?)?? You were going to share this R/O among the Linux servers which means you cannot update the disk when in use. There is probably little reason to journal the writes then. Also, we found that some journaling file systems have trouble mounting R/O.
