Nutanix AHV节点故障转移期间的故障转移

各位，

目前，我的Nutanix群集由3个Nutanix块组成，5个节点在AHV上运行20170830.171

1块3 NX-1065-G5节点
1块1 nx6035-g5
1块1 nx6035-g5

最近，由于硬件问题，NX6035-G5中的一项已关闭。
不知何故，该节点上托管的所有VM都无法自动为其他节点自动故障转移。
在与Nutanix进行检查后，我们被告知故障转移失败了，因为我们没有足够的可用内存。
我们被告知，AHV将对所有有足够资源来容纳它的特定节点执行所有故障VM的故障转移；就像将整个负载从失败节点移动到另一个节点一样。

以前，我们正在使用VMware，其中VM将通过VM进行故障转移VM到所有可用的节点。
有人遇到AHV的类似问题吗？

    \r\nCurrently my Nutanix cluster consist of 3 Nutanix block, 5 node running on AHV 20170830.171
    \r\n
    \r\n1 block of 3 NX-1065-G5 node
    \r\n1 block of 1 NX6035-G5
    \r\n1 block of 1 NX6035-G5

    \r\nRecently, one of the NX6035-G5 is down due to hardware issue.
    \r\nSomehow, all the VMs hosted on this node not able to auto failover to the others node.
    \r\nUpon checking with Nutanix, we were informed that the failover failed as we don't have sufficient available memory.
    \r\nWe were told that AHV will perform the failover for all the fail VMs to one particular node which have sufficient resources to accommodate it; like moving the whole load from the fail node to another node.
    \r\n
    \r\nPreviously we are using VMware where it will failover VM by VM to all the available nodes.
    \r\nAnyone encounter similar issue with AHV?","quoteUsername":"boonsoon.on-72320","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    你好 @boonsoon.on-72320

    您能分享案例号，比我可以看一看并检查有关此案的其他信息。

    但是，请记住，有不同的方法可以为HA上的AHV保留资源，并且根据您如何配置HA，您可能会期望不同的行为。

    查看以下链接，以进行有关AHV HA的良好介绍：

    \r\nCan you please share the case number than I can take a look and check additional information on the case.
    \r\n
    \r\nBut, keep in mind that there are different ways to reserve resources for HA on AHV and depending of how you configured the HA, you may expect different behaviors.

    \r\nTake a look at the following links for a good introduction about AHV HA:
