[Pacemaker] Only Xen primitives not in groups migrate on failover

[Roberto Giordani]

Hi Andrew,
probably ther is my mistake.
I'd like to add a second file system mounted on the guest xen, this file 
system is not the main files sytem where run the O.S., but is a file 
system that use the xen machine for file sharing for example.
Is it not possible?

Regards,
Roberto
