after-image journaling must be enabled to ensure recovery

  Explanation:  After adding an AIJ journal, it  is  necessary  to
  enable  AIJ  journaling (if it is not already enabled).  Failure
  to enable AIJ journaling will result in the AIJ file  being  NOT
  recoverable.

  User  Action:   IT  IS  HIGHLY  RECOMMENDED   that   after-image
  journaling be enabled AS SOON AS POSSIBLE.
