zpool upgrade freeness-boot

[Scharbag]

This is what my boot volume says after upgrading to TrueNAS 12-U1:

Code:

  pool: freenas-boot
 state: ONLINE
status: Some supported features are not enabled on the pool. The pool can
    still be used, but some features are unavailable.
action: Enable all features using 'zpool upgrade'. Once this is done,
    the pool may no longer be accessible by software that does not support
    the features. See zpool-features(5) for details.
  scan: scrub repaired 0B in 00:00:25 with 0 errors on Wed Dec 16 13:39:01 2020
config:

    NAME          STATE     READ WRITE CKSUM
    freenas-boot  ONLINE       0     0     0
      mirror-0    ONLINE       0     0     0
        da0p2     ONLINE       0     0     0
        da1p2     ONLINE       0     0     0

Just curious if this pool is ever upgraded or if it just will remain with the Status showing that it does not support all features.

This is not a important, just cosmetic.

Cheers,

It won't upgrade the pool to support the latest features unless you explicitly run:

Code:

zpool upgrade freenas-boot

I would leave it alone, as it's best to have a boot pool that is supported by an older version of FreeNAS / TrueNAS, in case you ever need to revert back. You're not really missing much of anything, unless there's a very real and specific need for the latest ZFS features.

As for your data pools, this "upgrade" process can be done via the GUI. Again, assess the pros and cons and if it's really worth it after reading about what the newest features provide.
