I´ve a problem with my lvm. I don't get it, why i have no free space on it. Another person done the installation, so it is hard to get the structure of the system.

I think the lvm is a raid 1 of 2 x 2 TB hard drives:

Code:

Actual free space after 1 VM with 15GB disk space: 1GB. But why?

It should be in a raid. The host is already a productive server, so i can't reinstall the whole Host. What is the best to do?
