>Description:
	When attempting to use an already-in-use cache device in another
	pool, the error message makes little sense (specifically the use
	of the word "unknown" below):

	invalid vdev specification
	use '-f' to override the following errors:
	/some/disk is part of unknown pool 'data'
>How-To-Repeat:
	# zpool create data ada1 cache da0
	# zpool create backups ada2
	# zpool status
	  pool: backups
	 state: ONLINE
	 scrub: none requested
	config:

	        NAME        STATE     READ WRITE CKSUM
	        backups     ONLINE       0     0     0
	          ada2      ONLINE       0     0     0

	errors: No known data errors

	  pool: data
	 state: ONLINE
	 scrub: none requested
	config:

	        NAME        STATE     READ WRITE CKSUM
	        data        ONLINE       0     0     0
	          ada1      ONLINE       0     0     0
	        cache
	          da0       ONLINE       0     0     0

	errors: No known data errors

	# zpool add backups cache da0
	invalid vdev specification
	use '-f' to override the following errors:
	/dev/da0 is part of unknown pool 'data'
>Fix:
	The word "unknown" should probably be "active", or better yet,
	removed altogether.
