Backup Error - not enough free space huh?

[WhiteSocks]

Hi,

I have a server from OVH and I personalized the installation from Proxmox CD (only partitions in fact) to add a /var/lib/vz/dump to backup my VMs. But when I try to backup one, I have this error:

INFO: starting new backup job: vzdump 100 --remove 0 --mode snapshot --compress lzo --storage backup --node ks2014544
INFO: Starting Backup of VM 100 (qemu)
INFO: status = running
INFO: backup mode: snapshot
INFO: ionice priority: 7
INFO: Volume group "pve" has insufficient free space (2 extents): 256 required.
ERROR: Backup of VM 100 failed - command 'lvcreate --size 1024M --snapshot --name 'vzsnap-ks2014544-0' '/dev/pve/VZ'' failed: exit code 5
INFO: Backup job finished with errors
TASK ERROR: job errors

I don't know why, and it makes me crazy. I don't understand why it says I haven't sufficient spaces. I allocated 250Gb to the dump directory.

Do you have an idea?

Thx.
Regards.

You need free space in the LVM volume group in order to allocate a LVM snapshot.
