Symptoms

尝试创建卷时，用户在控制器驱动程序日志中看到以下错误。表述性状态转移 （REST） 命令检索有关 SG 的详细信息。REST 响应为“200 ok”，但随后日志在日志中显示“Unable to find storage group”。

接着，REST 会检查卷是否存在，然后再尝试创建它。REST 返回找不到卷，并显示 404 Not Found。但代码需要一个空列表。

然后重复此行为，并且永远不会创建卷。

Cause

用户在输入 Unisphere for PowerMax 端点时，在值文件或 powermax-reverseproxy-config 和 powermax-array-config configmaps 中添加了尾随“/”。

https://primary-1.unisphe.re:8443/

提供的值 YAML 文件在示例中不显示尾随“/”。

https://primary-1.unisphe.re:8443

 

Resolution

应使用不包含附加“/”的值文件执行安装。

Additional Information

要在日志中查看 POWERMAX HTTP REQUEST 或 RESPONSE，请启用 powerMaxDebug：

请参阅文档并按照适用于特定环境的部署说明进行作： https://dell.github.io/csm-docs/

logLevel— CSI 驱动程序日志级别。允许的值：“error”， “warn”/“warning”， “info”， “debug”
powerMaxDebug — 启用 CSI 驱动程序与 Unisphere 之间的低级别和 http 流量日志记录。除非支持团队要求，否则请勿启用此功能。
