调整共享¶
对于大多数驱动程序，调整共享是一项安全的操作。如果您想确保数据的安全，可以通过创建其快照来备份共享。
您可以使用 openstack share resize 命令扩展和缩小共享，并指定新的大小不超过配额的共享。有关详细信息，请参阅 配额和限制。您也不能将共享大小缩小到 0 或大于当前共享大小的值。
注意
从 API 版本 2.53 开始，扩展一个复制的共享，manila 配额系统将为两个额外的配额预留和消耗资源：share_replicas 和 replica_gigabytes。如果扩展共享及其所有共享副本没有可用的配额，则此请求将失败。
在扩展过程中，共享具有 extending 状态。这意味着增加共享大小的请求已成功发出。
要扩展共享并检查结果，请运行
$ openstack share resize docs_resize 2
$ openstack share show docs_resize
