I use Regina to link/mount my rpm/iso disks and unmount/detach them when
I'm done.
It seems to work fine, but it is rather very low utilization (a flurry
of activity for a couple days every 3-6 months or so), but I don't know
if it would break under heavier utilization.

If you can live with the disk being unavailable for a while, you could
obviously do it like this:
1. umount the disk on all clones
2. take it in write mode on the master
3. update
Is that the only way?
I would have thought that the Linux machine that has write access,
would first have to umount the disk (or what ever way you have to flush
the cache to dasd). Then the readonly Linux machines would have to
umount the disk to invalidate any blocks that are in cache so any ne

What is it you want to do?
Do you mean unmounting and remounting a filesystem? If that's the
case, then the answer is "yes" unless the filesys
The CP LINK command will update the guest machine to reflect a change in a MDISK
in the directory. I don't think Linux would like having a mounted disk changed.
But you could unmout the old disk, link to the new one, and then mount it again.

You mean Linux has it R/O and someone else has been writing to it? I
hope you know you should not...
If you unmount the file system it will
