Log:
  Merge r240371:
      When synchronizing, include in the config dump amount of
    bytes syncronized.
      The rationale behind this is the following: for large disks the
    percent synchronisation counter ticks too seldom, and monitoring
    software (as well as human operator) can't tell whether
    synchronisation goes on or one of disks got stuck. On an idle
    server one can look into gstat and see whether synchronisation goes
    on or not, but on a busy server that won't work. Also, new value
    monitored can be differentiated obtaining the synchronisation speed
    quite precisely.
