ZPOOL-UPGRADE(8) FreeBSD System Manager's Manual ZPOOL-UPGRADE(8)
NAME
zpool-upgrade - manage version and feature flags of ZFS storage pools
SYNOPSIS
zpool upgrade
zpool upgrade -v
zpool upgrade [-V version] -a|pool<?>
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 -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.
EXAMPLES
Example 1: Upgrading All ZFS Storage Pools to the Current Version
The following command upgrades all ZFS Storage pools to the current
version of the software:
# zpool upgrade -a
This system is currently running ZFS version 2.
