    cyclades: Fix wait-for-sync on stopped instances · 30fd1f7f
    Christos Stavrakakis authored
    Pass 'wait_for_sync' option only on started Ganeti instances, because Ganeti
    will fail with 'OpPrereqError' in case the 'wait_for_sync' is set to
    False and the instance has deactivated disks.
    Note that Cyclades will not let a user neither attach a volume to an instance
    that is is in transition state, e.g. stopping, nor change the state of
    an instance if there is a pending volume attachment. However, in case
    the administrator manually modifies the instance via Ganeti, there is a
    race between checking the state of the instance and the time that Ganeti
    job will run that cannot be prevented.
    Closes grnet/synnefo#314
