Re: [Xen-users] how xen recognizes fibre channel based storage resources
Hello
you can share the same block device to several DomUs, just add 'w!' to
the options to say: "yes, write access to more than one". if you use
only 'w', Xen would complain at the second DomU that tries to use it,
which is a reasonable safeguard when you don't use cluster-aware
filesystems.
Thanks for your answer but if I understand well you assume in your
answer that domu's sharing block device are located on the same physical
server while they are not.
I would like to create on four physical servers virtual machines that
must to have simultaneous access to the same FC volume (blck device) -
therefore no communication between domus0 will be established to
synchronize writes as you suggests: "yes, write access to more than one".
Is it possible to do something I'd like to do?
Thanks for your help.
Piotr
