Which 2.2.x? LVM isn't supported in 2.2.18pre17 or any other previous version.

For some irrelevant reason I always test snapshotting on a LV with minor
number > 1 and the kernel side definitely works with 2.2.18pre17aa1:

laser:/home/andrea # ls -l /dev/vg1/lv*
brw-r----- 1 root root 58, 0 Oct 27 2000 /dev/vg1/lv0
brw-r----- 1 root root 58, 1 Oct 27 2000 /dev/vg1/lv1
laser:/home/andrea # lvcreate -s -n lv1-snap /dev/vg1/lv1 -L 400M
lvcreate -- INFO: using default snapshot chunk size of 64 KB
lvcreate -- doing automatic backup of "vg1"
lvcreate -- logical volume "/dev/vg1/lv1-snap" successfully created

laser:/home/andrea # lvremove -f /dev/vg1/lv1-snap
lvremove -- doing automatic backup of volume group "vg1"
lvremove -- logical volume "/dev/vg1/lv1-snap" successfully removed

laser:/home/andrea #
