Hello.
Can I use external snapshot for fast zero allocation?
 "thpool" - is lvmthin with lvm zeroing disabled

# lvcreate -n ext2T -V 2TiB --thinpool thpool VG
# lvchange --permission r VG/ext2T

# lvcreate -n zeroed_lve -s VG/ext2T --thinpool VG/thpool

Or it will be the same as zeroing enabled?
Thanks.
