openstack cinder - 磁盘配额管理

磁盘配额由 Swift 1.8 (OpenStack Grizzly) 管理

Container Quotas: Limits the total size (in bytes) or number of objects that can be stored in a single container.
Account Quotas: Limits the total size (in bytes) that a user has available in the Object Storage service.

1. [[email protected] ~(keystone_admin)]# cinder help | grep quota
2. quota-class-show    List the quotas for a quota class.
3. quota-class-update  Update the quotas for a quota class.
4. quota-defaults      List the default quotas for a tenant.
5. quota-show          List the quotas for a tenant.
6. quota-update        Update the quotas for a tenant.
7. quota-usage         List the quota usage for a tenant.

配额默认针对 tenants 级别, 倒不如改成针对用户级别更方便管理

下面方法限制用户在所有 project 中的磁盘总大小

/etc/glance/glance-api.conf

[plain] view plaincopyprint?

1. user_storage_quota = 0  <- 以 byte 进行计算 ex: 5368709120 (5G)

ex: icehouse 版本后, 需要修改配置文件 glance-api.conf 中 image_member_quota 配置

默认配额配置文件
/etc/cinder/cinder.conf

[plain] view plaincopyprint?

1. #quota_volumes=10
2. #quota_snapshots=10
3. #quota_gigabytes=1000
