Snapshots with OpenVz

[dundee]

Hi,
I'm wondering what is the best way to do LVM snapshots for OpenVz containers.

In the default confguration all containers are places in one logical volume (data), so when doing backup of one container via LVM snapshot, the whole volume is being snapshoted which I think can lead to IO performance lost.

I was looking for some similar solution which is available for KVM (Proxmox creates new logical volume for VM on selected volume group), but I haven't found anything like this in Proxmox 2.3.

How are you doing this? What do you think is the best way? Do you create logical volumes for containers manually or use just one volume for all of them?

Thanks

Any best practice or recommendation?

Not sure if I understand you question as it just works.

If you want to to backups by using LVM snapshots, just do it.
See http://pve.proxmox.com/wiki/Backup_and_Restore

I know that it works, but I'm not sure if it's good idea to do LVM snapshot of the whole lv where all data of all containers are placed.

So my question is if you do it like this (all containers on one lv) in production or if you create one lv per container (manually).

I have no issues here but you can setup as many storage's as you like. test it.
