The cinder.scheduler.manager Module

Scheduler Service

class SchedulerManager(scheduler_driver=None, service_name=None, *args, **kwargs)

Bases: cinder.manager.Manager

Chooses a host to create volumes.

RPC_API_VERSION = '3.0'

create_consistencygroup(context, topic, group, request_spec_list=None, filter_properties_list=None)

create_group(context, topic, group, group_spec=None, group_filter_properties=None, request_spec_list=None, filter_properties_list=None)

create_volume(context, topic, volume_id, snapshot_id=None, image_id=None, request_spec=None, filter_properties=None, volume=None)

get_pools(context, filters=None)

Get active pools from scheduler’s cache.

NOTE(dulek): There’s no self._wait_for_scheduler() because get_pools is an RPC call (is blocking for the c-api). Also this is admin-only API extension so it won’t hurt the user much to retry the request manually.

init_host_with_rpc()

manage_existing(context, topic, volume_id, request_spec, filter_properties=None, volume=None)

Ensure that the host exists and can accept the volume.

migrate_volume_to_host(context, topic, volume_id, host, force_host_copy, request_spec, filter_properties=None, volume=None)

Ensure that the host exists and can accept the volume.

request_service_capabilities(context)

reset()

retype(context, topic, volume_id, request_spec, filter_properties=None, volume=None)

Schedule the modification of a volume’s type.

Parameters:

• context – the request context
• topic – the topic listened on
• volume_id – the ID of the volume to retype
• request_spec – parameters for this retype request
• filter_properties – parameters to filter by
• volume – the volume object to retype

target = <Target version=2.3>

update_service_capabilities(context, service_name=None, host=None, capabilities=None, **kwargs)

Process a capability update from a service node.
