My snapshot need is not "absolutely required" but would have been a bonus (in fact I installed 2.6.1 for exactly «the fast and efficient snapshot of lvm2» compared to the lvm1 one I heard here and there). thanks a lot for your kind help see you, Xtian. > > As for the ioctl interface, you should leave the "version 4" turned on, since > that is the default now.
