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.

For example:

$ project_id=$(openstack project show -f value -c id PROJECT_NAME)

List the default quotas for a project:

$ cinder quota-defaults PROJECT_ID

For example:

$ cinder quota-defaults $project_id
+-----------+-------+
|  Property | Value |
+-----------+-------+
| gigabytes |  1000 |
| snapshots |   10  |
|  volumes  |   10  |
+-----------+-------+

View Block Storage service quotas for a project:

$ cinder quota-show PROJECT_ID

For example:

$ cinder quota-show $project_id
+-----------+-------+
|  Property | Value |
+-----------+-------+
| gigabytes |  1000 |
| snapshots |   10  |
|  volumes  |   10  |
+-----------+-------+

Show the current usage of a per-project quota:

$ cinder quota-usage PROJECT_ID

For example:

$ cinder quota-usage $project_id
+-----------+--------+----------+-------+
|    Type   | In_use | Reserved | Limit |
+-----------+--------+----------+-------+
| gigabytes |   0    |    0     |  1000 |
| snapshots |   0    |    0     |   10  |
|  volumes  |   0    |    0     |   15  |
+-----------+--------+----------+-------+

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.conf file. For more information, see the Block Storage service in OpenStack Configuration Reference.

To update Block Storage service quotas for an existing project

$ cinder quota-update --QUOTA_NAME QUOTA_VALUE PROJECT_ID

Replace QUOTA_NAME with the quota that is to be updated, QUOTA_VALUE with the required new value, and PROJECT_ID with the required project ID.

For example:

$ cinder quota-update --volumes 15 $project_id
$ cinder quota-show $project_id
+-----------+-------+
|  Property | Value |
+-----------+-------+
| gigabytes |  1000 |
| snapshots |   10  |
|  volumes  |   15  |
+-----------+-------+

To clear per-project quota limits:
```
$ cinder quota-delete PROJECT_ID
```
