How do I clear this problem? :-)

Development system here where I've been screwing around with ZFS and ZPOOL.

I have a deprecated mirror that cannot be imported (the disks used for
it were wiped and re-used); however, an attempt to destroy the pool
fails because it's not mounted, and I can't find a command to clear the
cache data that ZPOOL is using to find it.

[root at dbms2 /]# zpool import
   pool: zstore
     id: 4828844235736846012
  state: UNAVAIL
 status: One or more devices are missing from the system.
 action: The pool cannot be imported. Attach the missing
        devices and try again.
   see: http://illumos.org/msg/ZFS-8000-3C
 config:

        zstore                    UNAVAIL  insufficient replicas
          mirror-0                UNAVAIL  insufficient replicas
            6822277834587078071   UNAVAIL  cannot open
            17152979047208821543  UNAVAIL  cannot open
          mirror-1                UNAVAIL  insufficient replicas
            9208768479824103717   UNAVAIL  cannot open
            2616541439243568493   UNAVAIL  cannot open

Correct, none of the devices can be found (the system bitches loudly on
the console about this, incidentally.)

[root at dbms2 /]# zpool destroy zstore
cannot open 'zstore': no such pool
[root at dbms2 /]# zpool destroy 4828844235736846012
cannot open '4828844235736846012': name must begin with a letter
[root at dbms2 /]#

Attempts to drop the devices in the mirror (to take it apart
"piecemeal") also fail.

How do I clear this deprecated entry that cannot be brought back
online?  I can't completely clear EVERYTHING related to ZFS because
there is another pool that is current in-service and working.

I can't find anything in the man pages that addresses this......
