Move OpenVZ Container from one local storage to another

[Danik]

I need to Move OpenVZ Container from one storage to another and wanted to ask what will be the shortest downtime way?
For now I plan to do it with backup and then restore, but container size is 400gb and it will take at least several hours of downtime, which is very unlikely.
Is there any way that it could be done with less downtime?

p.s. I tried just to copy container files on test server but after coping and modifying config files – quota errors did not allowed to start container.
p.p.s. Using Proxmox 3.0

anyone ?

use tar or cpio for the job.

is there any way I can do it not to backup -> to some storage and then restore from some storage
just to do a copy or backup and restore at one step
if I just copy files - quota error does not allow me to start this copy - may be there is way how to fix quota error ?

[Danik]

it did not helped
so if anyone need it this one worked for me

# vzquota drop <vmid>
# vzctl start <vmid>

As I wrote earlier, I would really welcome an advanced migrate interface where you could not only set target node, but target storage as well.
It would be a very logical advancement, since Proxmox supports a diverse array of storage options, and a backup-restore requires considerable downtime.
