DESCRIPTION¶
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

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.
