ZFS & vzdump

[dlasher]

ok, I know I must be missing something obvious, but I can't make vzdump work well with ZFSonLinux (Same box solution). When I first ran into this, I figured, "I'll just enable snapshots on the ZFS side, and forget the backups", but now, 12 months later, I'd actually like to try to solve it.

vzdump can't snapshot without LVM, so no snapshot.
vzdump can't suspend without LVM, so no suspend.
vzdump can only stop the VM, which leaves it down for, sometimes a lengthy period, depending on the size of the image.

I'm 100% happy with ZFSonLinux, it's given me everything i wanted in terms of IO performance, reliability, etc.. Now if I could just get snapshots to work with vzdump.

I even considering going with some form of LVM on top of a ZVOL, but I'm not sure if I want that much risk.. (and I don't especially like LVM anyway)

I'm curious what other people are doing? Ideas?

There is currently no plan to support openvz snapshot backup with zfs (zfs is not
on the list of supported file system for OpenVZ).

Works fine now in PMX 4.x
