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

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 the default quota values for the initial deployment, update the values of the quota_* config options in the /etc/cinder/cinder.conf file. For more information, see the Block Storage service configuration.

Note

The values of the quota_* config options are only used at the initial database sync in the initial deployment. If you want to change a default value for a new project, see the following.

To update a default value for a new project, set use_default_quota_class = True (which is the default setting) in the DEFAULT section of the /etc/cinder/cinder.conf file, and run the command as the following.
```
$ openstack quota set --class default --QUOTA_NAME QUOTA_VALUE
```
Replace QUOTA_NAME with the quota that is to be updated, QUOTA_VALUE with the required new value.

To update Block Storage service quotas for an existing project

$ openstack quota set --QUOTA_NAME QUOTA_VALUE PROJECT_ID

Replace QUOTA_NAME with the quota that is to be updated, QUOTA_VALUE with the required new value. Use the openstack quota show command with PROJECT_ID, which is the required project ID.

For example:

$ openstack quota set --volumes 15 $PROJECT_ID
$ openstack quota show $PROJECT_ID
