zpool
upgrade- Displays pools which do not have all supported features enabled and pools
formatted using a legacy ZFS version number. These pools can continue to
be used, but some features may not be available. Use
zpool
upgrade
-a to enable all features on all pools
(subject to the -o
compatibility property).
zpool
upgrade
-v- Displays legacy ZFS versions supported by the this version of ZFS. See
zpool-features(7) for a description of
feature flags features supported by this version of ZFS.
zpool
upgrade
[-V
version
]
-a|pool…- Enables all supported features on the given pool.
If the pool has specified compatibility feature sets using the
-o
compatibility property, only the features
present in all requested compatibility sets will be enabled. If this
property is set to legacy then no upgrade
will take place.
Once this is done, the pool will no longer be accessible on systems that do
not support feature flags. See
zpool-features(7) for details on
compatibility with systems that support feature flags, but do not support
all features enabled on the pool.
-a- Enables all supported features (from specified compatibility sets, if
any) on all pools.
-V
version- Upgrade to the specified legacy version. If specified, no features
will be enabled on the pool. This option can only be used to increase
the version number up to the last supported legacy version
number.
