      Description

      TrueNAS-SCALE-20.10-MASTER-20201001-092914

      Removed drive from a pool for testing.  Pool shows as degraded.  When you reinsert the drive, pool continues to show as degraded.  Running zpool status results in:

       

      jeffnas05# zpool status tank
       pool: tank
       state: DEGRADED
       status: One or more devices could not be used because the label is missing or
          invalid.  Sufficient replicas exist for the pool to continue
          functioning in a degraded state.
      action: Replace the device using 'zpool replace'.

      errors: No known data errors

      The only way available that I have found to clear this and make the pool healthy after drive reinsertion is 'zpool clear tank'
