As I understand it, you cannot currently use multiple disks for a rpool (IE: something similar to raid10). Are there plans to provide this functionality, and if so does anyone know what the general timeframe is? Thanks! -- This message posted from opensolaris.org
A root pool is composed of one top-level vdev, which can be a mirror (i.e. 2 or more disks). A raidz vdev is not supported for the root pool yet. It might be supported in the future, but the timeframe is unknown at this time.

I don''t know if that changes the answer (doubtful), but raidz/raidz2 was not being discussed. -- Carson

That might change in the future, but there is no projected date for relaxing that constraint. Lori
