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：

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

3. 可选： 使用- -all 选项返回其他输出。

   这个命令查询环中的所有服务器以获取以下数据：

   • async 待处理：如果集群负载过高，进程无法足够快更新数据库文件，则一些更新异步进行。随着时间的推移，这些数字会缩短。
   • 复制指标：检查复制时间戳；通常发生完整的复制通过，以及几个错误。旧条目（例如，带有 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六个月内完成。
   • Ring md5sums： 这样可确保所有 ring 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：所有节点必须不能或非常少、数量非常高的文件。
   • time-sync ：所有节点必须同步。
