class IgnoreAttemptedHostsFilter

Bases: cinder.scheduler.filters.BaseBackendFilter

Filter out previously attempted hosts

A host passes this filter if it has not already been attempted for scheduling. The scheduler needs to add previously attempted hosts to the ‘retry’ key of filter_properties in order for this to work correctly. For example:

 'retry': {
           'backends': ['backend1', 'backend2'],
           'num_attempts': 3,
backend_passes(backend_state, filter_properties)

Skip nodes that have already been attempted.
