During backup i get this error, it does the same for a snapshot or suspend the only way i can get backups without error is to use the stop method ... oddly only some openvzs not all

Code:

OpenVZ only works with ext3, ext4 and NFS - ZFS is not supported by OpenVZ.

But we support containers on ZFS with Proxmox VE 4.0, using LXC instead of OpenVZ.
 
Thanks Dietmar, and i was just reading through the v3x to v4x upgrade documentation and will be doing the upgrade ASAP
 
Quick question for clarity around this.

I setup a new server with Proxmox 3.4 on it and create a RAID 10 ZFS disk. Now I can create Containers and vzmigrate containers from solusvm on it. You state above OpenVZ does not support ZFS but does work on proxmox 4 - is there something or missing or did wrong then? or am I just misunderstanding and still tired :)
 
You stated this "OpenVZ only works with ext3, ext4 and NFS - ZFS is not supported by OpenVZ."

Are you referring backups only?
