Do RH or the community want in integrate the changes in dmsetup - is
there maybe a timeline for this ?
My task is to take n (e.g. n=5) identical snapshot(snap1-5.LV) from a
xen-image (base.LV) and run
5 Xen-VM's (based on snap1-5.LV) on 5 different XEN-Server (phy.HW).
If this could not done with CLVM2, i have to change the concept to use
GFS/OCFS2.
regards
Danny
