Hi Tony,
Good questions...
Yes, you can assign a spare disk to multiple pools on the same system,
but not shared across systems.
The problem with sharing a spare disk with a root pool is that if the
spare kicks in, a boot block is not automatically applied. The
differences in the labels is probably another problem.
My advice is:
1. Mirror the root pool. If you want additional protection for the root
pool, then create a 3-way mirror (by attaching the spare disk).
2. Keep a spare disk physically connected to the system but not
logically connected to either pool as a spare. You would have to
manually replace if a disk in either pool fails. Plus, if a disk fails
in a root pool mirror, you should confirm that it has an SMI label.
Thanks,
Cindy

The only problem is one pool is "rpool" with an SMI label and the other
pool is a standard ZFS pool?
Thanks
