Hello,

I'm running Proxmox 3.3 on SP-64 from OVH.

2x 240 GB SSD RAID 1 /data/ssd
2x 2 TB SATA RAID 1 /data/hdd

I have mounted the OVH Backup space via BFS in /mnt/pve/backup-1

If I try to backup an OpenVZ Container on the HDD:

Code:

If I try to backup an OpenVZ Contrainer on the SSD:

Code: 
[COLOR=#000000][FONT=tahoma]INFO: starting new backup job: vzdump 100 --remove 0 --mode snapshot --compress lzo --storage backup-1 --node pve-2[/FONT][/COLOR]

If I backup an KVM to the Backup Space I don't get any errors and it works fine.

I have tried to find something.

There is no free PE Size :( I'm a noob in partition-things and I really need help with this! I never had the problem before and I hope that someone can provide me a easy solution without reinstalling the whole machine...

thanks,
