No, I'm afraid there's no z/VM "magic" that could be invoked
here....sharing dasd (and therefore a file system) is a task the
operating systems themselves must handle.
But, as Rob van der Heij has pointed out, z/VM does now provide support
for file systems in a DCSS that would make the sharing happen at very
fast speed.

Hi, Marian.
I would suggest that you look into using one of the
Linux file systems
that are meant to be shared by various Linux images,
be they virtual
under z/VM or real on Intel hardware.
1) OpenAFS (the folks over at Sine Nomine
http://www.sinenomine.net/
know a lot about this one....)
2) IBM's GPFS (although I don't know if this is
available for zLinux yet.)
3) RedHat's Global File System (original done by
Sistina, I believe...)
http://www.redhat.com/software/rha/gfs/
These are all pure Linux file systems; there is no
z/VM involvement at
all, except for z/VM providing the normal hypervisor
functions for Linux
guests.

There was a thread couple of weeks ago about
sharing
filesystems using a way which didn't work.
If I want to share fs read/write for several Linux
images under z/VM, does z/VM helps with it ?
So far the only possibility I know is to run NFS
server and mount its r/w exported fs to other
images.
Are there any other possibilities to share fs r/w
?
Thank you
