Allowing modification of thin snap volumes with upstream commit: https://www.redhat.com/archives/lvm-devel/2012-October/msg00014.html
Could you please correct the typo in the error message? [root@r6-node01:~]$ lvchange -pr snapper_thinp/POOL Change permissions of thin pool "POOL" not yes supported. Verifying the fix works as such with lvm2-2.02.98-2.el6.x86_64.
