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. (If	a pool has specified compatibility feature sets	using
	     the -o compatibility property, only the features present in all
	     requested compatibility sets will be enabled on that pool.)

     zpool upgrade -v
	     Displays legacy ZFS versions supported by the current software.
	     See zpool-features(5) for a description of	feature	flags features
	     supported by the current software.

     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 re-
	     quested compatibility sets	will be	enabled.)  Once	this is	done,
	     the pool will no longer be	accessible on systems that do not sup-
	     port feature flags.  See zpool-features(5)	for details on compat-
	     ibility with systems that support feature flags, but do not sup-
	     port all features enabled on the pool.

	     -a	     Enables all supported features (from specified compati-
		     bility sets, if any) on all pools.

	     -V	version
		     Upgrade to	the specified legacy version.  If the -V flag
		     is	specified, no features will be enabled on the pool.
		     This option can only be used to increase the version num-
		     ber up to the last	supported legacy version number.
