症状
  • S3 客户端性能降低
  • 存储节点内存耗尽
  • 可能的存储节点崩溃(蓝色状态)
  • 可能的存储节点 LDR 服务崩溃(蓝色状态)
  • 存储节点上的 CPU 使用率较高
  • 100 秒以上的“最坏情况阻止( MSBx )”
    • GMI -> 存储节点 -> LDR -> 资源

 

原因

为桶启用 LATM 时

  • 当 ODR 被销毁时、 S3 请求将尝试将所有对象段推入 ILM
  • PushWithSegments 将数据段 UUID 元数据查找到将数据段纳入 ILM 队列中
  • 由于 ade 内核认为 ODR 已失效、所以从不向其发送 C* 操作响应、 OBDR 也不会退出
