Is it possible to build a RaidZ with 3x 1TB disks and 5x 0.5TB disks, and then swap out the 0.5 TB disks as time goes by? Is there a documentation/wiki on doing this?
Yes, you can build a raidz vdev with all of these drives but only 0.5TB will be used from your 1TB drives. Once you replace *all* of the 0.5TB drives with 1TB drives, then the full space of the 1TB drives will be used.
Depending on how likely it is that you will replace all of these old drives, you might consider using the new drives to add a second vdev to the pool so that the disk space on all the existing drives may be fully used and you obtain better mutiuser performance.
