I installed the CT FileServer and was looking how to mount a host directory to it.
This server is running PVE 3.1-21, while the other two (production servers) are
running PVE 3.0. I bought the community subsciption, but have not installed it yet.
I want to upgrade 3.0 to 3.2 without a new install.
The keys arrived today by E-Mail.
I saw a strage error message when issuing "lvs"

It seems that something is completely wrong. I only remember that
I did an upgrade 3.0 to 3.1 long time ago.

Can someone help me?
