The cinder.objects.cluster Module

class Cluster(context=None, **kwargs)

Bases: cinder.objects.base.CinderPersistentObject, cinder.objects.base.CinderObject, cinder.objects.base.CinderComparableObject

Cluster Versioned Object.

Method get_by_id supports as additional named arguments:

• get_services: If we want to load all services from this cluster.

• services_summary: If we want to load num_nodes and num_down_nodes

  fields.

• is_up: Boolean value to filter based on the cluster’s up status.

• read_deleted: Filtering based on delete status. Default value “no”.

• Any other cluster field will be used as a filter.

OPTIONAL_FIELDS = ('num_hosts', 'num_down_hosts', 'services')

classmethod get_all(context, is_up=None, get_services=False, services_summary=False, read_deleted='no', **filters)

Get all clusters that match the criteria.

Parameters:

• is_up – Boolean value to filter based on the cluster’s up status.
• get_services – If we want to load all services from this cluster.
• services_summary – If we want to load num_nodes and num_down_nodes fields.
• read_deleted – Filtering based on delete status. Default value is “no”.
• filters – Field based filters in the form of key/value.
