scrub does verify checksums.
Yes, if the vdev would be a mirrored one, which it wasn't. There weren't any
mirrors setup. Plus, if the checksums would have been bad, scrub would have to
deteteced that. It would not have been to resolve it, but that wasn't the case.
zpool status backupPool_01
pool: backupPool_01
state: ONLINE
scrub: none requested
config:
NAME STATE READ WRITE CKSUM
backupPool_01 ONLINE 0 0 0
c3t2100001378AC0253d0 ONLINE 0 0 0
c3t2100001378AC026Ed0 ONLINE 0 0 0
errors: No known data errors
If one of the two devices would go bad, boom - that it'd be for the entire
pool, but as long as the two devices work, it's okay.
