zpool upgrade issue?

[Teske, Devin]

Hi,

I recently upgraded a ZFS pool on my system and the reported version
changed from "14" to "-" and I'm wondering if this is a bug.

dteske at hvm2a ~ $ zpool list
NAME          SIZE  ALLOC   FREE    CAP  DEDUP  HEALTH  ALTROOT
LSI-RAID1    1.39T  6.58G  1.39T     0%  1.00x  ONLINE  -
NEC2_POOL_A  3.91T   126K  3.91T     0%  1.00x  ONLINE  -
dteske at hvm2a ~ $ zpool status
  pool: LSI-RAID1
 state: ONLINE
status: The pool is formatted using a legacy 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 software that does not support feature
	flags.
  scan: none requested
config:

	NAME        STATE     READ WRITE CKSUM
	LSI-RAID1   ONLINE       0     0     0
	  mfid0s1g  ONLINE       0     0     0
