Bases: cinder.scheduler.filters.BaseHostFilter
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': {
'hosts': ['host1', 'host2'],
'num_attempts': 3,
}
}
Skip nodes that have already been attempted.
