cinder.objects.consistencygroup module¶

class ConsistencyGroup(context=None, **kwargs)¶

Bases: CinderPersistentObject, CinderObject, CinderObjectDictCompat, ClusteredObject

OPTIONAL_FIELDS = ('cgsnapshots', 'volumes', 'cluster')¶

VERSION = '1.4'¶

property availability_zone¶

property cgsnapshot_id¶

property cgsnapshots¶

property cluster¶

property cluster_name¶

create(cg_snap_id=None, cg_id=None)¶

Create a consistency group.

If cg_snap_id or cg_id are specified then volume_type_id, availability_zone, and host will be taken from the source Consistency Group.

property created_at¶

property deleted¶

property deleted_at¶

property description¶

destroy()¶

fields = {'availability_zone': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'cgsnapshot_id': UUID(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'cgsnapshots': Object(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'cluster': Object(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'cluster_name': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'created_at': DateTime(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'deleted': Boolean(default=False,nullable=True), 'deleted_at': DateTime(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'description': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'host': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'id': UUID(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=False), 'name': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'project_id': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=False), 'source_cgid': UUID(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'status': ConsistencyGroupStatus(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True,valid_values=('error', 'available', 'creating', 'deleting', 'deleted', 'updating', 'error_deleting')), 'updated_at': DateTime(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'user_id': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=False), 'volume_type_id': String(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True), 'volumes': Object(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=True)}¶

from_group(group)¶

Convert a generic volume group object to a cg object.

property host¶

property id¶

model¶

alias of ConsistencyGroup

property name¶

obj_load_attr(attrname)¶

Load an additional attribute from the real object.

This should load self.$attrname and cache any data that might be useful for future load operations.

property project_id¶

save()¶

Save the changed fields back to the store.

This is optional for subclasses, but is presented here in the base class for consistency among those that do.

property source_cgid¶

property status¶

property updated_at¶

property user_id¶

property volume_type_id¶

property volumes¶

class ConsistencyGroupList(*args, **kwargs)¶

Bases: ObjectListBase, CinderObject

VERSION = '1.1'¶

fields = {'objects': List(default=<class 'oslo_versionedobjects.fields.UnspecifiedDefault'>,nullable=False)}¶

classmethod get_all(context, filters=None, marker=None, limit=None, offset=None, sort_keys=None, sort_dirs=None)¶

classmethod get_all_by_project(context, project_id, filters=None, marker=None, limit=None, offset=None, sort_keys=None, sort_dirs=None)¶

static include_in_cluster(context, cluster, partial_rename=True, **filters)¶

Include all consistency groups matching the filters into a cluster.

When partial_rename is set we will not set the cluster_name with cluster parameter value directly, we’ll replace provided cluster_name or host filter value with cluster instead.

This is useful when we want to replace just the cluster name but leave the backend and pool information as it is. If we are using cluster_name to filter, we’ll use that same DB field to replace the cluster value and leave the rest as it is. Likewise if we use the host to filter.

Returns the number of consistency groups that have been changed.
