Proxmox backup failure (ovh promox install)

What are the file systems in your volume group? Either resize one of those or delete one.

That's already clear. But how can this be fixed ?
The fysical harddisk is big enough...

You don't have any free space left in your volume group to create snapshot.

The server is a PROXMOX v1.8 READY installed from OVH, upgraded some time ago to 1.9 - but also before this upgrade I had the above upgrade.

Some time ago, I get my 2nd OVH-server (this time with a PROXMOX 1.9 ready to go system from OVH): this new one doesn't have this problem.

So, it seems the PROXMOX installation from OVH is changed (and improved). I would like to fix the 1st server too !

I have tried a few things, but I can't fix it...
I am desperate !
I hope somebody can help ?
Many thanks in advance !
