第 5 章 配置 Object Storage 服务 (swift)

流程

1. 登录到其中一个 Controller 节点。

2. 运行以下命令：

   [root@overcloud-controller-2 ~]# sudo podman exec -it -u swift swift_object_server /usr/bin/swift-recon -arqlT --md5

3. 可选：使用 --all 选项返回附加输出。

   此命令查询环中的所有服务器以获取以下数据：

   • async pendings ：如果集群负载太大，且进程无法快速更新数据库文件，则一些更新会异步进行。这些数字随着时间的推移会减少。
   • 复制指标：检查复制时间戳；完整复制传递经常发生，并显示几个错误。例如，一个旧条目（例如，自 6 个月前的时间戳的条目）表示节点上的复制还没有在最后的 6 个月内完成。
   • 环形 md5sums ：这样可确保所有环文件在所有节点上都一致。
   • Swift.conf md5sums ：这样可确保所有配置文件在所有节点上都一致。
   • Quarantined 文件：所有节点必须无或非常少。
   • Time-sync ：所有节点都必须同步。
