Several improvements to the operation of the 'compatibility' property: 1) Improved handling of unrecognized features: Change the way unrecognized features in compatibility files are handled. * invalid features in files under /usr/share/zfs/compatibility.d only get a warning (as these may refer to future features not yet in the library), * invalid features in files under /etc/zfs/compatibility.d get an error (as these are presumed to refer to the current system). 2) Improved error reporting from zpool_load_compat. Note: slight ABI change to zpool_load_compat for better error reporting. 3) compatibility=legacy inhibits all 'zpool upgrade' operations. 4) Detect when features are enabled outside current compatibility set * zpool set compatibility=foo <-- print a warning * zpool set feature@xxx=enabled <-- error * zpool status <-- indicate this state Reviewed-by: Brian Behlendorf <behlendorf1@llnl.gov> Signed-off-by: Colm Buckley <colm@tuatha.org> Closes #11861

Displays pools which do not have all supported features enabled and pools
|
|
formatted using a legacy ZFS version number.
|

|
|
.Fl o Ar compatibility
|
|
property).

|
|
If the pool has specified compatibility feature sets using the

|
|
property, only the features present in all requested compatibility sets will be
|
|
enabled. If this property is set to
|
|
.Ar legacy
|
|
then no upgrade will take place.
|
|
.Pp
|
|
Once this is done, the pool will no longer be accessible on systems that do not
|
|
support feature flags.
|
|
See
|
|
.Xr zpool-features 5
|
|
for details on compatibility with systems that support feature flags, but do not
|
|
support all features enabled on the pool.
