+-----------+-------+
|  Property | Value |
+-----------+-------+
| gigabytes |  1000 |
| snapshots |   10  |
|  volumes  |   10  |
+-----------+-------+

  2. View Block Storage service quotas for a project.

    $ cinder quota-show TENANT_NAME

    For example:

    $ cinder quota-show tenant01

+-----------+-------+
|  Property | Value |
+-----------+-------+
| gigabytes |  1000 |
| snapshots |   10  |
|  volumes  |   10  |
+-----------+-------+

  3. Show the current usage of a per-tenant quota:

    $ cinder quota-usage tenantID

|    Type   | In_use | Reserved | Limit |
+-----------+--------+----------+-------+
| gigabytes |   0    |    0     |  1000 |

  3. To update Block Storage service quotas, place the tenant ID in a variable.

    $ tenant=$(openstack project show -f value -c id tenantName)

  4. Update a particular quota value.

    $ cinder quota-update --quotaName NewValue tenantID

    For example:

    $ cinder quota-update --volumes 15 $tenant
$ cinder quota-show tenant01

|  Property | Value |
+-----------+-------+
| gigabytes |  1000 |
| snapshots |   10  |
|  volumes  |   15  |
