Hi


The reason is very simple here - lvm2 does not work from containers.
It's unsupported and if it partially works - it's a pure lucky case.

ATM it's simply clear statement that lvm2 cannot be used from container simply 
because block layer is not namespaced.

I'd give here long list of reason why it currently cannot work, but for now  - 
you should focus on making all 'device-block' operation on you host - and pass 
results to container.

Regards

Zdenek
