ZFS feature set 2.4.4 vs 2.4.3



  • It seems that 2.4.4 has a zpool different feature set than 2.4.3. On 2.4.3 i have

    $zpool status
      pool: zroot
     state: ONLINE
      scan: none requested
    config:
    
            NAME        STATE     READ WRITE CKSUM
            zroot       ONLINE       0     0     0
              mirror-0  ONLINE       0     0     0
                ada0p4  ONLINE       0     0     0
                ada1p4  ONLINE       0     0     0
    
    errors: No known data errors
    

    After upgrading to 2.4.4 snapshot i have,

    $zpool status
     pool: zroot
    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(7) for details.
     scan: none requested
    config:
    
           NAME        STATE     READ WRITE CKSUM
           zroot       ONLINE       0     0     0
             mirror-0  ONLINE       0     0     0
               ada0p4  ONLINE       0     0     0
               ada1p4  ONLINE       0     0     0
    
    errors: No known data errors
    

    Is it better to re-create the pool with 2.4.4?



  • I would wait until 2.4.4 is officially released. You won't miss out on anything important now by leaving the pool as it is.

    # zpool get all zroot | grep feature@
    

    and then check for which ones are "disabled"
