Symptoms

 

  • 在有问题的 SVM 的 ESXi 主机上，RAID 控制器驱动程序lsi_mr3报告本地数据存储的底层磁盘上中止，并且 ESXi 报告丢失对卷的访问权限。

在 VMkernel 日志中：

  • SDS 设备可以报告任务中止（可在 var/log/messages 和 VMware 日志中找到），因此此 SVM 上的 SDS 进程将经历较长的飞行 IO，这会进一步影响 scaleio 系统的稳定性

 

  • SDC 随后在 VMkernel 日志中记录 IO 错误，因为有问题的 SDS 由于本地数据存储的响应缓慢而遇到一些网络套接字问题，并且驻留在 ScaleIO 卷上的应用程序数据存储可能会报告访问丢失：

Impact

 

影响

SDC 可能无法访问驻留在 PowerFlex 卷上的数据存储区，并且这些数据存储区上的应用程序或虚拟机可能会受到影响，例如，文件系统变为只读状态。
 

Cause

  • VMFS 数据存储区通过大约每 3 秒从主机向 VMFS 卷发出一次写入作形式的心跳进行监视。当 SVM 的本地数据存储响应缓慢时，检测信号 I/O 的总时间未在 16 秒窗口内完成，数据存储标记为离线，并且 hostd 会生成“失去对卷的访问”日志消息以反映此行为。有关更多详细信息，请参阅 VMware 知识库 文章了解 ESXi 中对卷的丢失访问消息 
  • 在这种情况下，无法预测 SDS 的确切行为，例如，哪些其他 PowerFlex 组件会丢失 keepalive 消息。必须由此 SDS 提供服务的某些 SDC IO 可能会超过作系统或应用程序的超时时间，从而造成影响。

Resolution

联系 VMware 和硬件供应商以修复 RAID 控制器或其固件和驱动程序上的问题。

Additional Information

临时解决方法是删除有问题的 SDS，或将其迁移到另一个良好的本地数据存储。
