The thin-provisiong-tools package has landed in Sid a few days ago:

Can it still be included in Saucy so that the feature may be stabilized for 14.04 LTS?

4 years later and this is still an issue on Ubuntu 16.04/Linux 4.4/LVM 2.02.133.

## break attempting to detach then fix;

apt-get install thin-provisioning-tools

vgexport vg_test

#thin-provisioning-tools should be a dependency of lvm2.

On CentOS 7.2/Linux 3.10 lmv2 depends on device-mapper-persistent-data which is what they call thin-provisioning-tools

repoquery --requires lvm2
yum info device-mapper-persistent-data.x86_64

5 years later an this is still and issue on 17.10. It's possible to create complex LVMs setups, e.g. the one described at, but then at the first mount the missing `/usr/sbin/check_cache` binary causes the mount to fail until `thin-provisioning-tools` is installed.
