Please try:

--table "0 2147483581 linear /dev/zvol/dsk/tank/backup/vhost/vol/net-export 34"

left side is the offset + size of a chunk of your new mapped device

right side is the backing store (must be the block device) and the offset on 
the backing store.


This worked great! This helps me tremendously - I can now mount the replicated ZVOL snapshots of my VMs directly on the NAS. This is much more convenient and faster than replicating the ZVOL back to the vhost if the worst comes to the worst.

Kind regards
Matthias
