Ran into a situation and not sure how to proceed. We wanted to migrate our boot pool off the current set of Mirrored drives to a new set of mirrored drives. We (incorrectly) detached one drive from the boot-pool and went to attach a new one. This however errors out stating 3-way mirrors are not supported.
Now we’re left with the 2 devices marked as part of the boot pool but only one device actually listed IN the boot pool and now sure how to proceed.
What is the proper way to either add the SDF drive back into the pool and or migrate to a new set of disks for our boot-pool?
