大家好！

我的Nutanix集群有4个节点运行AHV版本Nutanix 20170830.337和AOS版本5.10.9.1 LTS。

突然，其中一个节点出现CVM不可达的问题。当我运行集群状态命令得到消息1 CVM down。

我试着运行nodetool -h 0 ring得到这样的东西。

当我发出cmd ncli主机列表。我注意到问题节点收到了这条消息“标记为要添加回元数据存储的节点”

我的一个同事试图修复主机启动设备，但没有运气。

我们现在该怎么办?

@dot_slash<\/user-mention>\u00a0Please upgrade your cluster as I can see the AHV and AOS versions are old and this can cause lots of issues.

Hi\u00a0Everyone,<\/p>

\u00a0My Nutanix cluster had 4 node running AHV version Nutanix 20170830.337 and AOS version 5.10.9.1 LTS.<\/p>

Suddenly, one of the node had CVM unreachable issue. When I\u2019m running cluster status command got message 1 CVM down.<\/p>

I\u2019m try to run\u00a0nodetool -h 0 ring got something like this.\u00a0<\/p>

When I\u2019m issue cmd ncli host list. I\u2019m notice the problem node got this message \u201cNode marked to be added back to metadata store\u201d<\/p>

1 of my colleague try to repair host boot device but no luck.<\/p>

嗨 @dot_slash看来，主机宕机很长时间了。登录主机控制台vi IPMI，查看主机当前状态。根据“nodeool -h 0 ring”提示，node由于不可用被从元数据环中分离出来。

Hi\u00a0@dot_slash<\/user-mention>, it looks like, host is down for a long time. Login to host console vi IPMI and check the current status of the host. Based on the \"nodetool -h 0 ring\" output, node is detached from metadata ring due to unavailability.<\/p>","quoteUsername":"Bala Murali Krishna","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨 @dot_slash主机还在关机吗?如果是，请张贴IPMI控制台的屏幕截图?还提供cs | grep -v UP的输出。

如果主机停机，可能是硬件问题。请用Nutanix打开箱子以获得进一步的帮助。

Hi @dot_slash<\/user-mention>\u00a0is host still down? if yes, could you please post screen shot for\u00a0the IPMI console? Also provide output of cs | grep -v UP.<\/p>

if host is down, this might be a hardware issue. Please open case with Nutanix for further assistance.<\/p>","quoteUsername":"Bala Murali Krishna","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨 @Bala Murali克利须那神

主机。AHIV正在运行，但CVM没有连接。

cs | grep -v UP如下所示

这个主机是nutanix的eol & eosl，但我们仍然使用它作为容灾集群

Hi @Bala Murali Krishna<\/user-mention>\u00a0<\/p>

host is up. AHIV running, but CVM no connection.<\/p>

cs | grep -v UP as below<\/p>

\"//www.jhbzcj.com/next/installation-configuration-23/\"<\/figure>

This host is eol & eosl by nutanix but we still using it as\u00a0DR\u00a0cluster\u00a0<\/p>","quoteUsername":"dot_slash","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@dot_slash请升级您的集群，因为我可以看到AHV和AOS版本是旧的，这可能会导致很多问题。棱镜5.15 -卫城升级指南(nutanix.com)如果不尽快升级，您可能会遇到集群停机的情况。

年代

@dot_slash第一个故障排除技巧是让您的集群保持更新，因为旧版本可能会导致许多您无法理解的问题(当然，如果您有一个糟糕的一天)。请按照官方文档升级您的集群，并记住升级的顺序。

@dot_slash<\/user-mention>\u00a0First troubleshooting tip is to keep your cluster up-tp-date as the older versions can cause lots of issues which you cannot comprehend (If you are having a bad day of course).Please follow the official doc for upgrading your cluster and the order of the upgrade is also to keep in mind.<\/p>","quoteUsername":"Syed Waheed","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
