Simple script to copy zfs vdevs (partitions) from one zpool to another with a progress bar :)

zfs_copy.sh

#!/bin/sh
source=$1
dest=$2
snapshot=$3

size=$(zfs send -nP $source@$snapshot 2>&1 | grep size | awk '{print $2}')

echo "$source@$snapshot -> $dest: $size"
zfs send $source@$snapshot | pv --timer --progress --eta --rate --average-rate --bytes --size $size --cursor --name $source | zfs receive -Fvu $dest
