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 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 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
