MSCS（Microsoft Server集群）

R
AHV是否支持MSC？我知道有两个节点Windows群集，下面提到的证人VM：

但只想确认它是否支持具有共享存储的MSC，包括仲裁？

Hello there,<\/p>

Failover clustering is supported on AHV by enabling MPIO on Guest OS Windows Server level.Leveraging MPIO enables the Guest to completely takeover the control for ability to determine which failover peer should write on the shared vDisk. Following documentation lists out the steps to leverage Volume Group from Nutanix Cluster to be presented to the VMs for configuring In-Guest clustering.

我认为使用iSCSI卷组你可以有一个共享存储通过网络仲裁和其他数据为您的虚拟机的。我目前在ESXi中使用它，但我认为在AHV中应该是相同的概念。

i think using iSCSI Volume Group you can have a shared storage over network for Quorum and other data for your VM's. I am currently using it in ESXi, but i think it should be the same concept in AHV.<\/p>","quoteUsername":"eng_asfour","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

嗨rekha ,,

您可以使用Nutanix卷（ABS）的卷组用于此用例，Nutanix卷使用SCSI-3对MSC的持久性，您可以使用Data Services IP作为iSCSI目标而不使用iSCSI MPIO。

\r\nYou can use volume group which is Nutanix Volumes (ABS) for this use case, Nutanix volumes uses scsi-3 persistence for MSCS, You can use data services ip as iscsi target without using iscsi mpio.

NFS存储平台不支持故障转移集群。您需要向集群提供外部iSCSI存储，以便进行故障转移集群。如果你一直在集群中寻找像SQL，它本质上只是一个连续的复制，那么是的，它是被支持的。这不是hypervisor的问题，而是来自微软的NFS不兼容。Nutanix有“受支持的”方法，但您需要与支持一起工作。

你好,

AHV通过在Guest OS Windows Server级别上启用MPIO来支持故障转移集群。利用MPIO使Guest能够完全接管控制，以决定应该在共享vDisk上写入哪个故障转移对等点。以下文档列出了使用Nutanix Cluster中的Volume Group的步骤，该步骤将呈现给虚拟机，用于配置In-Guest集群。

是的，它支持，我在现任雇主中建立了一些。在最佳实践之后，我为每个驱动器构建了Nutanix中的单独卷组;备份，数据，日志，仲裁，tempdb是呈现给节点VM的所有单独卷组。

Yes, it\u2019s supported and I\u2019ve built some here at my current employer.\u00a0I built separate Volume Groups in Nutanix for each of the drives for the cluster following best practices; Backups, Data, Logs, Quorum, TempDB are all separate Volume Groups presented to the node VMs.\u00a0<\/p>","quoteUsername":"jlackman","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我在卷组中使用ISCSI启动并运行这个程序，唯一的问题是，当在我们的容灾环境中启动它时，它无法访问那里的ISCSI，我被迫尝试并在Nutanix中使用VM Attached启动它。在DR做这件事没有任何问题。

I have this up and running using the ISCSI for the Volume Groups, only problem is when bringing it up in our DR environment it cannot access the ISCSI there and I am forced to try and bring it up with just VM Attached in Nutanix. Nothing but issues trying to do that in DR.\u00a0<\/p>","quoteUsername":"BSchaffer","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@BSchaffer我不确定我理解了，但我的第一个问题是，您确定保护域中除了实际的虚拟机之外还有MSCS卷组吗?

@BSchaffer<\/user-mention>\u00a0not sure I understand but my first question would be are you sure you have the MSCS volume groups in the Protection Domain, in addition to the actual VMs?<\/p>","quoteUsername":"jlackman","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

@jlackman是的，它们在保护范围内。

问题是，在生产集群中，它们是通过使用Nutanix中的数据服务IP通过iSCSI连接的。在我们的容灾集群中，这是不可能的，因为这是一个隔离的环境，他们无法访问Nutanix容灾集群的数据服务IP，因为它处于隔离之外。所以当我试着把他们带到那里去测试我必须移除vg上的iSCSI复选框，然后通过Nutanix连接到VM。这将导致在Windows集群中启动角色的各种问题，SQL服务将不能正确启动。

@jlackman<\/user-mention>\u00a0yes they are in the protection domain.<\/p>

\u00a0<\/p>

The problem is that in the Production cluster they are attached via iSCSI by using the Data Services IP in Nutanix. In our DR cluster this is not possible as it is an isolated environment and they cannot access the Data Services IP of the Nutanix DR cluster as it is outside the isolation. So when i try to bring them up out there to test i have to remove the iSCSI check boxes on the VGs and then attach to the VM through Nutanix. This is causing all kinds of issues in getting the Roles to start in the Windows Cluster, SQL services will not start correctly.<\/p>","quoteUsername":"BSchaffer","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

明白了。我们还需要一些手动步骤来在DR环境中生成MSCS。我们有一个低优先级的努力来解决这个问题，但我没有任何我知道的解决方案，在一个孤立的环境中把它带回来。

Got it. We also have some manual steps required to bring up MSCS in the DR environment. We have a low priority effort to sort this out but I do not have any solution that I know about to bring it back up in an isolated environment.\u00a0<\/p>","quoteUsername":"jlackman","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
