    Adding a member to a vdev does not automatically move any of the parity or data distribution off the old vdev.

    Yes it does. ZFS does a full resilver after the addition. Jim Salter’s write ups are from 4 years ago. Shit changes.

    Edit: and even if it didn’t… It’s trivial to write a script that rewrites all the data to move it into the new structure. To say there’s no valid cases when even in 2021 there was an answer to the problem is a bit crazy.
