no free space in volume group

[TechLineX]

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:

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

Hi,
your lvm isn't on a raid!! Otherwise you see only one PV and not two PVs with the same ID. Looks like a broken software-raid... so perhaps it's not clear, which version will use (mean, it's dangerous for your data).

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?
