vz backups with snapshots on nas or nfs possible?

[sahostking]

While I look into this a bit further though can someone guide me on this. We setup a Proxmox server with 64GB memory and ZFS raid 10 with 6 x 2TB disks.

Now I can install and create openvz containers as we use proxmox 3.4 we don't believe in using the latest version as yet. Rather give a few weeks or few months before moving to newer versions like version 4 so bare with me.

I have a few CentOS NFS servers working and setup in Proxmox nodes. Just set these up last night. Never used them before was so used to HyperV and Data Protection Manager

How do I get it to do live migrations for OpenVZ containers using proxmox vzdump options with nfs?

Getting this error:
INFO: mode failure - unable to detect lvm volume group

We have LVM on NFS server.
/dev/mapper/VG0-backups 3.6T 779G 2.8T 22% /backups

Will openmediavault help as a NAS?

or must I have a partition locally on server and break ZFS raid 10 and create 1 drive as LVM to get this working?

running openvz on a not supported filesystem like zfs seems also not perfect. re-consider using 4.0.

vzdump is for backup. so not related to live migrations.

Getting this error:

vzdump needs LVM for doing snapshot backups. as NFS is not LVM, you cannot do live backups. only suspend works here. (or stop, of course).

We have LVM on NFS server.
/dev/mapper/VG0-backups 3.6T 779G 2.8T 22% /backups

that is not relevant here.

for openvz on 3.4 yes. in 4.0 and lxc, all this is MUCH better.
