管理块存储服务配额¶

作为管理员用户，您可以更新 OpenStack 块存储服务的项目配额。您还可以更新新项目的配额默认值。

块存储配额

属性名称	定义了
千兆字节	每个项目允许的卷的千兆字节数。
快照	每个项目允许的卷快照数。
volumes	每个项目允许的卷数。

查看块存储配额¶

管理员用户可以查看块存储服务配额。

获取项目 ID

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

注意

使用 OpenStack 命令行客户端列出默认配额将提供存储和网络服务的所有配额。之前，cinder quota-defaults 命令只会列出存储配额。您可以使用 $PROJECT_ID 或 $PROJECT_NAME 参数来显示块存储服务配额。如果 $PROJECT_ID 参数在定位资源时返回错误，请使用 $PROJECT_NAME。

查看项目的块存储服务配额

$ openstack quota show --volume $PROJECT_ID

编辑和更新块存储服务配额¶

管理员用户可以编辑和更新块存储服务配额。

要更新初始部署的默认配额值，请更新 /etc/cinder/cinder.conf 文件中的 quota_* 配置选项的值。有关更多信息，请参阅块存储服务配置。

注意

这些 quota_* 配置选项的值仅在初始数据库同步的初始部署中使用。如果您想更改新项目的默认值，请参见以下内容。

要更新新项目的默认值，请在 /etc/cinder/cinder.conf 文件的 DEFAULT 部分设置 use_default_quota_class = True（这是默认设置），并运行以下命令。
```
$ openstack quota set --class default --QUOTA_NAME QUOTA_VALUE
```
将 QUOTA_NAME 替换为要更新的配额，将 QUOTA_VALUE 替换为所需的新值。

要更新现有项目的块存储服务配额

$ openstack quota set --QUOTA_NAME QUOTA_VALUE PROJECT_ID

将 QUOTA_NAME 替换为要更新的配额，将 QUOTA_VALUE 替换为所需的新值。使用 openstack quota show 命令和 PROJECT_ID，即所需的项目 ID。

例如

$ openstack quota set --volumes 15 $PROJECT_ID
$ openstack quota show $PROJECT_ID
