How do you expand your pool in Raidz?
For example, if you run a ZFS pool based on a single 3-disk RAIDZ vdev (RAID5 equivalent 2), the only way to expand a pool is to add another 3-disk RAIDZ vdev 1. You can’t just add a single disk to the existing 3-disk RAIDZ vdev to create a 4-disk RAIDZ vdev because vdevs can’t be expanded.
