Manage Block Storage service quotas¶

View Block Storage quotas¶

Administrative users can view Block Storage service quotas.

1. Obtain the project ID.

   For example:

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

2. List the default quotas for a project (tenant):

   $ cinder quota-defaults PROJECT_ID
   

   For example:

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

3. View Block Storage service quotas for a project (tenant):

   $ cinder quota-show PROJECT_ID
   

   For example:

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

4. 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.

1. Clear per-project quota limits.

   $ cinder quota-delete PROJECT_ID
   

2. 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 Configuration Reference.

3. To update Block Storage service quotas for an existing project (tenant)

   $ cinder quota-update --QUOTA_NAME QUOTA_VALUE PROJECT_ID
   

   Replace QUOTA_NAME with the quota that is to be updated, NEW_VALUE with the required new value, and PROJECT_ID with 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  |
   +-----------+-------+
   

4. Clear per-project quota limits.

   $ cinder quota-delete PROJECT_ID
   

Remove a service¶

1. Determine the binary and host of the service you want to remove.

   $ cinder service-list
   +------------------+----------------------+------+---------+-------+----------------------------+-----------------+
   |      Binary      |         Host         | Zone |  Status | State |         Updated_at         | Disabled Reason |
   +------------------+----------------------+------+---------+-------+----------------------------+-----------------+
   | cinder-scheduler |       devstack       | nova | enabled |   up  | 2015-10-13T15:21:48.000000 |        -        |
   |  cinder-volume   | devstack@lvmdriver-1 | nova | enabled |   up  | 2015-10-13T15:21:52.000000 |        -        |
   +------------------+----------------------+------+---------+-------+----------------------------+-----------------+
   

2. Disable the service.

   $ cinder service-disable HOST_NAME BINARY_NAME
   

3. Remove the service from the database.

   $ cinder-manage service remove BINARY_NAME HOST_NAME
