This isn’t quite so flexible; if you are using RAID-Z you have to add a whole stripe (e.g. 4 more disks) at a time.

You can even remove a drive from a pool, assuming there’s enough space to store all the data without it. With a simple command, ZFS will rearrange your data so the drive you specify is no longer necessary, after which it can be removed.

This feature (zpool remove) is planned but not implemented yet.
