Actualización de agrupaciones de almacenamiento de ZFS

Si dispone de agrupaciones de almacenamiento ZFS de una versión anterior de Solaris, puede actualizarlas con el comando zpool upgrade para poder aprovechar las funciones de las agrupaciones en la versión actual. Asimismo, el comando zpool status notifica a los usuarios que los grupos están ejecutando versiones anteriores. Por ejemplo:

# zpool status
pool: tank
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.
scrub: none requested
config:
NAME           STATE     READ  WRITE  CKSUM
tank           ONLINE       0      0      0
   mirror-0    ONLINE       0      0      0
      c1t0d0   ONLINE       0      0      0
      c1t1d0   ONLINE       0      0      0
errors: No known data errors

La sintaxis siguiente es válida para identificar información adicional sobre una versión concreta y compatible:

# zpool upgrade -v
