If you don't detach the smaller drive, the pool size won't increase. Even
if the remaining smaller drive fails, that doesn't mean you have to detach

It will be because you detached all smaller drives. Also, even if a

That's why I'm asking. I think it should always mirror the partition table and
allocate exactly the same amount of space so that the pool doesn't suddenly
change sizes unexpectedly and require a disk size that I don't have at hand, to
put the mirror back up.

Hi Andrew,
Current releases that apply the bootblocks automatically during
a zpool attach operation are Oracle Solaris 10 8/11 and Oracle
Solaris 11.
Thanks,

Hi Pawel,
In addition to the current SMI label requirement for booting,
I believe another limitation is that the boot info must be
contiguous.
I think an RFE is filed to relax this requirement as well.
I just can't find it right now.
Thanks,
Cindy

Most *cheap* SSDs are SATA. But if you want to use them in a cluster

Hi Anon,
The disk that you attach to the root pool will need an SMI label

The syntax to attach a disk to create a mirrored root pool
