LVM Thin provisioning snapshots bug?

Hi,

I am testing LVM thin provisioning in Alpine 3.2.

Alpine fortunately has LVM2 compiled with thin provisioning support and the thin provisioning tools package is available in testing.

However when I create a thin snapshot the corresponding volume is not created in the pool.

Create the LVM Thinpool in a loopback device

fallocate -l 6G /tmp/lxc

losetup -f /tmp/lxc

pvcreate /dev/loop0

vgcreate vg0 /dev/loop0

lvcreate -l 95%FREE --type thin-pool --thinpool tp0 vg0

Create a logical volume
lvcreate -T vg0/tp0 -V 500M -n p1

Now when i create a snapshot with
lvcreate -s -n p2 vg0/p1

There is no error message but p2 does not show up in /dev/vg0/

lvdisplay shows p2 as inactive.

Any ideas how I can begin to debug this? The same thing works pretty decently in Ubuntu Trusty and Jessie where I also tested it.

Since no error message is provided, and /var/log/messages has no error I am a bit flummoxed.

Update - Problem solved below.
