Fascinating.
This looks like an undocumented change in the way a zpool status is
reported. I see the same thing here :
$ uname -a
SunOS mercury 5.10 Generic_142909-17 sun4u sparc SUNW,Sun-Blade-2500
$
$ zpool status
pool: mercury_rpool
state: ONLINE
status: The pool is formatted using an older on-disk format. The pool can
still be used, but some features are unavailable.
action: Upgrade the pool using 'zpool upgrade'. Once this is done, the
pool will no longer be accessible on older software versions.

See "mirror-0" ? I didn't do that.
Too bad the sources for zpool status are not open anymore :-(
