On the target server being replicated to, doing a

zfs set volmode=none <volume target>

works around the issue of the OS trying to make a dev in /dev/zvol...

One caveat, as when doing a restore I guess that will need to be unset. 
Not sure if bhyve disks need a value other than none to work or not.
