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.

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.
