RAIDz does not let you do this: Start from one disk, add another disk to mirror the data, add another disk to make it a RAIDz array, and add another disk to increase the size of the RAIDz array. Solaris software RAID5, Linux software RAID5, and many hardware systems with RAID5-like functionality, all support adding a disk to a RAID5 array. So it makes sense that people expect the same feature from RAIDz, a system that appears very similar to RAID5. As of now, RAIDz is missing this check mark. Personally I don't use RAIDz for this reason. -- This messages posted from opensolaris.org
