Volume group has insufficient free space

[Joshua2504]

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:

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

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,
Joshua

Any ideas?..

How much free space do you have on that SSD drive of yours? There was a post another post that was near about identical to your issue, I can't find it atm, but here's a similar post that you might want to investigate:

You can teach yourself about LVM by reading here:

http://tldp.org/HOWTO/LVM-HOWTO/

 

[tom]

you can also create backups in suspend mode - no LVM needed and also quite useful.

see http://pve.proxmox.com/wiki/Backup_and_Restore for all methods.

But in suspend mode, proxmox will shutdown the VM?

Can you explain it?

 

[tom]

no, it will suspend. test it!
