可能会有这样的情况，你要么关闭整个市场集群的托管Nutanix文件，或者只是AFS (Nutanix Files)集群．


优雅地关闭Nutanix文件和Nutanix AOS集群

  • 确认没有快照或复制发生。
  • 下电集群内所有guest虚拟机，仅fsvm(文件服务器虚拟机)和cvm(控制虚拟机)上电。


优雅地关闭fsvm集群

步骤1:停止所有文件服务

1.1:适用于AOS 5.0。x - 5.5.x:

密涅瓦停止fsvm

1.2:对于AOS 5.6及更高版本:

从任何CVM，输入"afs“命令提示符:

nutanix@cvm: afs

< afs >下文。停止*

的下文。停止*命令将停止Nutanix Files服务并下电fsvm所有文件服务器。


安全关闭AOS集群

当CVM处于上电状态时，在任意CVM上运行:

步骤1:优雅地停止AOS集群:

nutanix@cvm:集群停止


步骤2:优雅关闭AOS集群中的cvm:

一旦集群停止，我们可以通过以下方式关闭cvm:

nutanix@cvm: sudo shutdown -h now

现在可以将主机下电，进行维护或物理硬件重新定位。

---

让它回到联机- AOS和Nutanix文件集群

为了让AOS集群和Nutanix文件集群重新上线，我们将首先:

  1. 上电物理主机
  2. 确保所有cvm处于UP/Online状态(当主机启动时，cvm自动启动)
  3. 确保所有物理网络连接都已就绪并且是绿色的

步骤1:启动一个Nutanix AOS集群

当所有的CVM启动后，用用户'nutanix' ssh登录到一个CVM，然后运行:

集群开始

步骤2:验证AOS集群服务:

nutanix@cvm:集群状态(确保所有服务都已启动)


步骤3:上电Nutanix文件(AFS)集群

3.1 -在AOS 5.0上启动文件服务。x - 5.5.x

密涅瓦——开始

3.2 -启动AOS 5.6及以上版本的文件服务:

登录CVM虚拟机，并输入afs提示输入:

nutanix@cvm: afs

一旦进入afs提示

< afs >下文。开始*

start命令将启动所有文件服务器的fsvm并启动Nutanix Files服务。

3.5使用指南

There can be a situation where you have to either shutdown the entire AOS cluster <\/strong>hosting Nutanix Files, or just the Nutanix Files (AFS) cluster<\/strong>.<\/p>


Gracefully shutdown Nutanix Files and Nutanix AOS Cluster<\/h3>
  • Verify that no snapshot or replication is taking place.<\/li>
  • Power off all guest VMs on the cluster, leaving only FSVMs (File Server VMs) and CVMs (Controller VMs) powered on.<\/li><\/ul>


    Gracefully Shut\u00a0down a Nutanix FILES (FSVMs) Cluster<\/h3>

    \u00a0<\/p>

    STEP - 1 : Stopping all File Services <\/strong><\/p>

    1.1 : For AOS 5.0.x - 5.5.x:<\/strong><\/p>

    minerva stop fsvm<\/code><\/pre>
    1.2 :\u00a0FOR AOS 5.6 and later:<\/strong><\/p>
    From any CVM, enter the \"afs<\/code>\" command prompt:<\/p>
    nutanix@cvm: afs

    <afs> infra.stop *<\/code><\/pre>
    \u200bThe infra.stop *<\/code> command will stop Nutanix Files services and power off the FSVMs<\/strong> for all File Servers.<\/p>

    Gracefully Shutdown the AOS Cluster
    \u00a0<\/h3>
    Once only the CVMs remain powered on, from any CVM, run:<\/p>
    STEP 1 : Gracefully STOP\u00a0an AOS Cluster:<\/strong><\/p>
    nutanix@cvm: cluster stop<\/code><\/pre>

    STEP 2 : Gracefully shutdown the CVMs in an AOS Cluster:<\/strong><\/p>
    Once the cluster is stopped, we can then shutdown the CVMs itself via:<\/p>
    nutanix@cvm: sudo shutdown -h now<\/code><\/pre>
    You can now Power-off the\u00a0hosts to conduct maintenance or physical hardware re-location.<\/em><\/p>
    \u00a0<\/p>
    ---<\/p>
    Bringing it back online - AOS and Nutanix Files Cluster<\/h3>
    \u00a0<\/p>
    In order to bring back online a AOS Cluster and Nutanix Files Cluster, we will first:<\/p>
    1. Power ON the physical hosts<\/li> 
    2. Ensure all CVMs are UP\/Online (CVMs auto-start when hosts are up)<\/li> 
    3. Ensure all physical network connections are in-place and green<\/li><\/ol>
      STEP - 1 : Powering up a Nutanix AOS Cluster<\/h3>
      Once all CVMs are up, ssh login to a CVM with user 'nutanix' and run:<\/p>
      cluster start<\/code><\/pre>
      \u00a0<\/p>
      STEP - 2 : Verify AOS Cluster Services:<\/strong><\/h3>
      nutanix@cvm: cluster status (make sure all services are up)<\/code><\/pre>

      STEP - 3 :\u00a0Powering UP Nutanix Files (AFS) Cluster<\/h3>
      \u00a0<\/p>
      3.1 - Starting File Services on AOS 5.0.x - 5.5.x<\/strong><\/p>
      minerva -a start<\/code><\/pre>
      3.2 - Starting File Services on AOS 5.6 and later:<\/strong><\/p>
      Login to a CVM and enter the afs<\/code> prompt by typing:<\/p>
      nutanix@cvm: afs<\/code><\/pre>
      Once inside the afs<\/code> prompt<\/p>
      <afs> infra.start *<\/code><\/pre>
      The start command will power on the FSVMs for all File Servers and start Nutanix Files services.<\/strong><\/p>
