Manage Block Storage service quotas¶
As an administrative user, you can update the OpenStack Block Storage service quotas for a project. You can also update the quota defaults for a new project.
Block Storage quotas
| Property name | Defines the number of |
|---|---|
| gigabytes | Volume gigabytes allowed for each project. |
| snapshots | Volume snapshots allowed for each project. |
| volumes | Volumes allowed for each project. |
View Block Storage quotas¶
Administrative users can view Block Storage service quotas.
Obtain the project ID:
$ PROJECT_ID=$(openstack project show -f value -c id PROJECT_NAME)
List the default quotas for a project:
$ openstack quota show --default $PROJECT_ID +-----------------------+-------+ | Field | Value | +-----------------------+-------+ | backup-gigabytes | 1000 | | backups | 10 | | cores | 20 | | fixed-ips | -1 | | floating-ips | 50 | | gigabytes | 1000 | | gigabytes_lvmdriver-1 | -1 | | health_monitors | None | | injected-file-size | 10240 | | injected-files | 5 | | injected-path-size | 255 | | instances | 10 | | key-pairs | 100 | | l7_policies | None | | listeners | None | | load_balancers | None | | location | None | | name | None | | networks | 10 | | per-volume-gigabytes | -1 | | pools | None | | ports | 50 | | project | None | | project_id | None | | properties | 128 | | ram | 51200 | | rbac_policies | 10 | | routers | 10 | | secgroup-rules | 100 | | secgroups | 10 | | server-group-members | 10 | | server-groups | 10 | | snapshots | 10 | | snapshots_lvmdriver-1 | -1 | | subnet_pools | -1 | | subnets | 10 | | volumes | 10 | | volumes_lvmdriver-1 | -1 | +-----------------------+-------+
Note
Listing default quotas with the OpenStack command line client will provide all quotas for storage and network services. Previously, the cinder quota-defaults command would list only storage quotas. You can use $PROJECT_ID or $PROJECT_NAME arguments to show Block Storage service quotas. If the $PROJECT_ID argument returns errors in locating resources, use $PROJECT_NAME.

Edit and update Block Storage service quotas¶
Administrative users can edit and update Block Storage service quotas.
To update a default value for a new project, update the property in the cinder.quota section of the
/etc/cinder/cinder.conffile. For more information, see the Block Storage service in OpenStack Configuration Reference.To update Block Storage service quotas for an existing project
$ openstack quota set --QUOTA_NAME QUOTA_VALUE PROJECT_ID
Replace
QUOTA_NAMEwith the quota that is to be updated,QUOTA_VALUEwith the required new value. Use the openstack quota show command withPROJECT_ID, which is the required project ID.For example:
$ openstack quota set --volumes 15 $PROJECT_ID $ openstack quota show $PROJECT_ID +-----------------------+----------------------------------+ | Field | Value | +-----------------------+----------------------------------+ | backup-gigabytes | 1000 | | backups | 10 | | cores | 20 | | fixed-ips | -1 | | floating-ips | 29 | | gigabytes | 1000 | | gigabytes_lvmdriver-1 | -1 | | health_monitors | None | | injected-file-size | 10240 | | injected-files | 5 | | injected-path-size | 255 | | instances | 10 | | key-pairs | 100 | | l7_policies | None | | listeners | None | | load_balancers | None | | location | None | | name | None | | networks | 10 | | per-volume-gigabytes | -1 | | pools | None | | ports | 50 | | project | e436339c7f9c476cb3120cf3b9667377 | | project_id | None | | properties | 128 | | ram | 51200 | | rbac_policies | 10 | | routers | 10 | | secgroup-rules | 100 | | secgroups | 10 | | server-group-members | 10 | | server-groups | 10 | | snapshots | 10 | | snapshots_lvmdriver-1 | -1 | | subnet_pools | -1 | | subnets | 10 | | volumes | 15 | | volumes_lvmdriver-1 | -1 | +-----------------------+----------------------------------+
To clear per-project quota limits:
$ cinder quota-delete $PROJECT_ID
