Hello, we're trying to run vzdump on external HDD, but we got this error:

My HDD are formatted in ext3, without LVM volumes. It is mounted on /media/

How can I resolve that problem?

Your VM is on /dev/pve/data, which is ext3 on top of LVM.

You need some free space on the volume group if you want to make lvm snapshots. Our installer automatically reserves 4GB for that - seems you installed that not using our installer?
 
We have used the OVH pre-installed ISO.
Dont know how it works.

We attached the HDD in a second moment... After the installation of proxmox.
 
as Dietmar already posted, you need at least 4 GB free space for storing the snapshot, otherwise it will never work. as I do not know your OVH setup I suggest you contact OVH or post in their forums.

Ok, i will ask theme about the installation process.

However i do not understand how to show the size and free available space.
If is 4GB, how can i increase the space? (or clean that partition)?
