 # The reason why I wanted to do this was because I had a striped pool (a pool with no mirroring/redundancy) and
 # I wanted to convert it to a mirror pool which is not possible through the GUI (it is a bit complex via shell commands).
 # My solution was to copy the data from the striped pool to a temporary holding pool (a random disk that I had lying around)
 # and then recreate the pool as a mirrored pool and copy the snapshot back.

 # Start a tmux session so that the shell session will persist even when you close the shell
 tmux

 # Create a snapshot of pool_A that contains the data that you want moved to pool_B
 zfs snapshot -r pool_A@migrate

 # Send the snapshot to pool_B
 zfs send -R pool_A@migrate | zfs receive -F pool_B
