I'vd done something similar. I use a patch to enable writes on snapshots. Once I had to shrink a root filesytem on LVM. I created an writeable snapshot, rebooted with the snapshot as root filesystem. Thisway the real root fs wasn't mounted and I could shrink it without problems. > > Will it work tho?
