我有几个虚拟机正在构建一个windows故障转移集群。共享存储由通过iscsi绑定到虚拟机的NDFS卷组提供。
是否有可能创建一个启用vss的集群快照?

    嗨josegerez

    我们还不支持创建基于应用程序一致性(VSS) Nutanix的快照与iSCSI和卷组。

    谢谢,
    迈克

    \nWe don't yet support creating app-consistent (VSS) Nutanix based snapshots with iSCSI and volume groups.

    谢谢mmcghee．

    所以，没有办法在用虚拟机构建的windows集群中拥有应用一致的快照?

    \nSo, there's no way to have app-consistent snapshots in a windows cluster built with vms? 😞","quoteUsername":"josegerez","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    据我所知，用Nutanix的快照是不行的josegerez至少今天不是本土的，但让我们更详细地探索。

    您能描述一下您的申请和恢复要求吗?在需要时间点(快照时间)恢复的情况下，依我之见，依赖写一致性快照工作得即使不是更好，也一样好。Nutanix通过我们的stargate进程暂停写操作来确保依赖写一致性。

    VSS风格的快照需求通常需要在完整快照和增量日志或快照异步备份之间协调恢复。在这里，VSS是一个困难的需求。一个常见的场景是使用快照将SQL数据库恢复到加载状态(没有恢复或备用)，然后应用日志备份。要使用日志恢复类型的备份进行恢复，就需要像Commvault这样的第三方备份。我不得不推迟dlink7以及Commvault是否可以将VSS与卷组快照结合使用的问题。我不认为这是可能的，但我不完全确定。
    josegerez<\/a> at least not natively today, but let's explore in more detail.
    \n
    \nCould you please describe your application and recovery requirements? In cases where point-in-time (time of snapshot) recovery is required, dependent-write consistent snapshots work just as well if not better IMHO. Nutanix ensures dependent-write consistency by quiescing writes through our stargate process.
    \n
    \nVSS style snapshot requirements generally tie into coordinating recovery between a full snapshot and incremental log or differential backups taken asynchronously to the snapshot. Here, VSS is a hard requirement. A common scenario is using a snapshot to recover a SQL database into a loading state (no recovery or standby), and then applying log backups. To get restore with log recovery style backups a third party like Commvault for example would be required. I'd have to defer dlink7<\/a> or others on whether Commvault can leverage VSS in conjunction with volume group snapshots. I don't think it's possible but I'm not entirely sure.","quoteUsername":"mmcghee","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    我必须做一些调查，但我认为Commvault今天不能见到Volume Group。

    你好再次,mmcghee
    我们正试图用Nutanix替换netapp文件。
    在这个文件器中，我们使用NAS服务(通过CIFS)为windows客户端提供文件服务，但AFS此时没有文件夹或文件筛选配额。因此，我们认为可以用windows文件服务器虚拟机提供文件服务，但无需集群，我们可以在windows维护期间提供HA(你知道，周二补丁:()
    这就是我们需要vss的地方。我们向NAS文件器提供Netapp以前版本的特性。

    此外，我们使用filer为一堆物理SQL Server集群提供lun，并使用Commvault IntelliSnap特性进行备份。
    我们希望使用ABS为这些集群提供iSCSI lun，而不丢失基于快照的备份。
    mmcghee<\/a>
    \nWell, we're trying to replace a netapp filer with Nutanix.
    \nIn this filer we're using NAS services (via CIFS) to offer file services to windows clients, but AFS at this point has no quota by folder nor file screening. So, we think to offer file services with a windows file server vm but without clustering it we can provide HA during Windows maintenance (you know, tuesday patching :()
    \nAnd here is where we need vss. We're providing previous versions feature of Netapp to the NAS filer.
    \n
    \nAlso, we're using the filer to provide LUNs to a bunch of physical SQL Server clusters and doing backup with Commvault IntelliSnap feature.
    \nWe want use ABS to provide iSCSI LUNs to these clusters without losing the snapshot based backup.","quoteUsername":"josegerez","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    什么是文件筛选?AV吗?用户可以恢复他们的文件今天与Windows以前的版本与AFS。

    我dlink7，

    文件筛选是用来阻止特定文件类型(视频，音频，pst's， ....)在选定文件夹中的功能。
    Windows内置了这个功能。Netapp需要一个第三方工具来管理它。

    我知道AFS有Windows以前的版本支持，但它没有按文件夹或文件筛选配额，我们需要它们。
    只要我知道在AFS中服务器虚拟机使用iSCSI连接到存储数据的卷组。这是一个类似的配置，但我谈到的是windows机器。
    dlink7<\/a>,
    \n
    \nfile screening is the feature used to block certain file types (video, audio, pst's, ....) in selected folders.
    \nWindows has it builtin. Netapp needs a 3rd party tool to manage it.
    \n
    \nI know AFS has Windows previous versions support, but it hasn't quota by folder nor file screening and we need them.
    \nAs long as i know in AFS the server vm's use iSCSI to connect to volume groups storing data. It's a similar config I'm taking about but with windows machines.","quoteUsername":"josegerez","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
