Release 3.10 feature proposal : Introduce force option in snapshot restore

    Hi,

    
    Essentially a snapshot of a volume, which was taken when the
      volume had nfs.ganesha option enabled, has a export.conf file for
      it. This file will be restored to the Ganesha Export Directory,
      which has been moved to the shared storage. Currently we fail the
      snapshot restore in a scenario, where the snapshot has the said
      conf file, but the shared storage is not available. This behaviour
      is expected. However there is no option for the user to proceed
      with the snapshot at this point in time.
    We will introduce a force option for snapshot restore, which will
      enable the user to restore this particular snapshot in the above
      explained scenario, thereby abandoning the export.conf. The reason
      for introducing the force option is to make the user explicitly
      ask for the saved export.conf to be abandoned in such a scenario.
    Example of proposed option in restore cli:

      gluster snapshot restore [force]
    

    Here is the BZ: https://bugzilla.redhat.com/show_bug.cgi?id=1403188

    Regards,

    
    Avra
