I thoyght there was a zfs option that could > force the two non-equel disks to form a mirror. There was this fix in build 117:
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6844090 which allowed a slightly smaller disk (say, a block or two) to be attached to a mirror when it didn't violate the requirement that each side of the mirror have the same amount of usable space for file system contents. But if the disk being added is smaller than that, then the only way to attach it to the mirror would be to reduce the size of the pool (since by definition, all sides of a mirror must be able to hold the full pool) and reducing the size of a pool is not yet supported. There IS a force option that allows you to create a pool with disks of unequal sizes, but the resulting pool will be the size of the smallest disk. But there's no "force" option to allow a smaller device to be attached to an existing pool, since that would violate the concept of what it means to be a mirror.
