查询存储池
更新时间 2025-11-04 18:33:44

本节主要介绍使用命令行查询存储池。
OpenStack命令行：
openstack volume backend pool list --long
Cinder命令行：
cinder get-pools --detail
此命令用来查询存储池信息。
注意
修改/etc/cinder/cinder.conf配置文件中的参数local_storage_class，若与现有卷的存储类型属性不匹配，将会导致计算错误，影响查询结果的准确性。
多个存储类型共享同一存储池时，可能因存储空间交叉分配而导致查询信息出现偏差。
系统计算存储池容量时自动过滤缓存池资源。
