Well ... do USS and MVS understand MD, LVM and EVMS logical volume metadata? If not ... then you can't build the volumes that your file system lives within. So, your only going to be able to look at compatibility volumes built from partitions. Seems like a waste to not be able to use linear, mirroring or lvm volumes on a 390. >ext2/ext3/reiserfs write and read!

Why not run a cluster fs (e.g. opengfs) on mvs or uss (what is uss by the way?) and not worry about such things. >As to the data interlock issue, it could initially be >solved with two volumes >volume 1 rw to USS, ro to Linux >volume 2 rw to Linux, ro to USS >And invent a "refresh command" that rereads the meta >data on the ro system? >The refresh command would also allow ro filesystems to >be shared between Linux systems and and the systems >would not have to be rebooted to get updates.
