当主机上的驱动器（SSD或HDD）遇到可恢复的错误，警告或完整的硬件故障时，星形服务将标记磁盘。

发生磁盘发生故障时，可以观察到以下内容。

  1. 磁盘显示为棱镜的红色或普通灰色

  2. 棱镜中陈述磁盘的严重错误变坏了。

排除步骤

  1. 在棱镜中识别有问题的磁盘。

    1. 检查失败磁盘的棱镜Web控制台。在图表视图中，您可以查看缺失磁盘的红色或灰色。

    2. 检查磁盘警报中棱镜Web控制台中的警报，或者使用群集中的任何工作CVM中的以下命令检查已生成失败消息的磁盘。

NCLI警报LS.

  1. 检查黑色平面是否识别磁盘。从显示磁盘失败的节点的CM执行以下命令

list_diks.

  1. 检查磁盘是否已安装在节点上。

df -h.

  1. 使用NCC检查检查离线磁盘disk_online_check.。

ncc health_checks硬件_checks disk_checks disk_online_checks

  1. 使用以下命令检查磁盘的运行状况

sudo smartctl-h / dev / sdx（x可以是从步骤3的此磁盘的字母表）

在更换驱动器之前，需要CVM重新启动以正确显示驱动器失败，或者如果它应该重新返回以进一步排除并尝试在线携带它

When a drive on a host (SSD or HDD) experiencing a recoverable errors, warnings or a complete hardware failure, the stargate service will mark the disk as bad.<\/span><\/p>

\u00a0<\/p>

The following can be observed when a disk fail occurs.<\/span><\/p>

  1. \t

    Disk is shown as a red\u00a0 or a plain grey in prism<\/span><\/p>\t<\/li>\t

  2. \t

    A critical error in Prism stating the disk went bad.<\/span><\/p>\t<\/li><\/ol>

    \u00a0<\/p>

    Troubleshooting steps<\/span><\/p>

    \u00a0<\/p>

    1. \t

      Identify the problematic disk in Prism.<\/span><\/p>\t

      1. \t\t

        Check the Prism web console for the failed disk. In the Diagram view, you can see red or grey for the missing disk.<\/span><\/p>\t\t<\/li>\t\t

      2. \t\t

        Check the alerts in the Prism web console for the disk alerts, or use the following command from any of the working CVMs in the cluster to check for disks that have generated the failure messages.<\/span><\/p>\t\t<\/li>\t<\/ol><\/li><\/ol>

        ncli alert ls<\/span><\/strong><\/p>

        1. \t

          Check to see if the disk is being recognized by the black plane. Execute the following command from the cm of the node that shows disk fail<\/span><\/p>\t<\/li><\/ol>

          list_diks<\/span><\/strong><\/p>

          1. \t

            Check to see if the disk is mounted on the node.<\/span><\/p>\t<\/li><\/ol>

            df -h<\/span><\/strong><\/p>

            1. \t

              Check for offline disks using NCC check <\/span>disk_online_check<\/strong>.<\/span><\/p>\t<\/li><\/ol>

              ncc health_checks hardware_checks disk_checks disk_online_checks<\/span><\/strong><\/p>

              1. \t

                Check the health status of the disk using the following command<\/span><\/p>\t<\/li><\/ol>

                sudo smartctl -H \/dev\/sdX<\/span><\/strong>\u00a0 (X can be an alphabet of this disk from step 3)<\/span><\/p>

                \u00a0<\/p>

                Before replacing the Drive a CVM reboot is needed to properly show the Drive as failed or if it should come back to be able to troubleshoot further and try to bring it online<\/span><\/p>

是CVM重新启动（或任何这些命令/测试），如果磁盘列为“togbstoned”，则仍需要仍需要磁盘重新安装？

NCLI磁盘LS-TOMBStone-Atties

Is a CVM reboot (or any of these commands\/test) or a disk reseat still needed if the disk is listed as \u201ctombstoned\u201d?<\/p>
