Very many thanks for the link Andy, (almost the) same message posted to there. Fingers crossed...

Kind regards

I think you'll get more help on the ZFS mailing list.

    https://zfsonlinux.topicbox.com/groups/zfs-discuss

I've not tried, but VHD file are normally images of partitions or
disks, so you can turn them into a block device on Linux with
"losetup", e.g.

# losetup -Pf disk.vhd

gets you e.g. /dev/loop0p1

Presumably you can then somehow get zfs to scan all of those loop
block devices to see if it recognises anything it can work with.

Might be worth taking copies of the VHD file first, or at least
making them read-only/immutable, before messing with them…

Cheers,
Andy
