为什么Calm必须在Nutanix星团上呢?

嗨。

我是第一个承认我过快地阅读了关于Calm的文档，没有真正思考“Nutanix Calm运行的Prism Central在同一个集群中注册”的含义的人。和“Nutanix Calm仅支持在Nutanix集群的AHV和ESXi hypervisor上使用。”

在尝试在现有的VMware集群(Prism Central/Calm安装不属于该集群)上运行后，我重新阅读了文档，并意识到我忽略了实际需求。

我提到这一点是为了澄清这不是一个关于不明确的文档或不正确的需求的帖子。我犯了个错误，就这么简单。：）

我想知道的是为什么会有这些要求。我已经和我在Nutanix的联系人谈过了，到目前为止，我还没有得到这个问题的正确答案。

谁能详细解释一下，为什么我不能在任意虚拟机上运行Calm ?

    Hi.<\/p>

    I\u2019m the first to admit that I read the documentation for Calm a bit too quickly and didn\u2019t really reflect on the meaning of \u201cThe Prism Central in which Nutanix Calm is running is registered with the same cluster.\u201d and \u201cNutanix Calm is supported only on AHV and ESXi hypervisors on a Nutanix cluster.\u201d<\/p>

    After trying and failing to run this on an existing VMware cluster, that the Prism Central\/Calm installation doesn\u2019t own, I re-read the documentation and realized that I\u2019d glossed over the actual requirements.<\/p>

    I mention this to clarify that this isn\u2019t a post about unclear documentation or incorrect requirements. I goofed, as simple as that. :)<\/p>

    What I do want to know though is why these requirements exist. I have talked to my contacts at Nutanix and I so far I haven\u2019t got a proper answer to this question.<\/p>

    Can anyone please explain, in detail, why I can\u2019t run Calm on an\u00a0arbitrary VM?<\/p>","quoteUsername":"Martin Edelius","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    支持在ESXi上独立部署虚拟机。请检查链接．

    同样关于为什么这些要求存在于运行在nutanix集群上的PC虚拟机上的平静启用，它需要安装用于创建卷组的docker卷插件。Calm将任务日志和图标存储在创建的VG中。

    嗨 @charan - 49230！

    感谢您的回复和链接，当我与我在Nutanix的联系人交谈时，我没有提到这一点，我一定会发送给他们。：）

    这只会让我更加困惑。如果我可以在ESXi上运行一个独立的虚拟机与calm，为什么Prism Central VM与calm包含使用功能，只有在Nutanix集群上可用?

    为什么Calm要创建VG来存储日志和图标?这似乎是一个非常复杂的解决方案，它可以直接写入磁盘。

    Hi @charan-49230<\/user-mention>\u00a0!<\/p>

    Thanks for the reply and\u00a0for the link, that was not mentioned when I talked to my contacts at Nutanix and I\u2019ll be sure to send it to them. :)<\/p>

    This only confuses things more for me though. If I can run a stand-alone VM with calm on ESXi, why does the Prism Central VM with Calm included use functionality that is only available on a Nutanix cluster?<\/p>

    And why does Calm create VG\u2019s to store logs and icons? That seems like a really complex solution for something that can just be written to disk.<\/p>","quoteUsername":"Martin Edelius","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

    @Martin Edelius

    好问题。棱镜中心家庭磁盘空间的使用是有限制的。如果calm将日志和图标存储在同一路径中，则会导致磁盘空间问题。

    另一方面，calm VM是在PC上的自定义构建，带有额外的10gb磁盘，用于存储日志和图标。

    @Martin Edelius<\/user-mention>\u00a0<\/p>

    \u00a0<\/p>

    Good question. There is a limitation on the prism central home disk space usage. if calm stores the logs and icons in same path it leads to disk space issues.<\/p>

    On the other side, calm VM \u00a0is a custom build on top of PC with a additional disk of 10 GB that is used to store logs and icons.\u00a0<\/p>

    @charan - 49230

    我之所以提到这一点是因为在我看来这是使用Calm的障碍。在我当前的项目中，为了让PC/Calm正常工作，我们不得不做一些变通工作，而且我们必须把它放在它所管理的同一个集群上。当然，我们可以使用独立的Calm VM，但这不是最佳选择。

    对我来说，这听起来就像Ian Malcolm博士在评论《侏罗纪公园》中创造恐龙的科学家，而不是使用docker插件和VG存储日志的Nutanix工程师;“你们的科学家太专注于他们是否能做到，而没有停下来想想他们是否应该做到。”。)

    我想提出一些正式的功能要求，让PC/Calm完全独立，这样它就可以在任何地方运行——甚至是在云中的一个虚拟机上。

    谢谢你的回复。

    The reason I\u2019m mentioning this is because it in my opinion is a hindrance to the use of Calm. In my current project we had to do quite a bit of workaround to get PC\/Calm to work, and we had to place it on the same cluster it\u2019s managing. Sure, we could use the standalone Calm VM but that isn\u2019t optimal.<\/p>

    To me this sounds like when Dr. Ian Malcolm comments on the scientists creating dinosaurs in Jurassic Park, but instead its Nutanix engineers using docker plugins and VG\u2019s to store logs; \u201cYour scientists were so preoccupied with whether or not they could, they didn't stop to think if they should.\u201d ;)<\/p>

    I would like to make some sort of official feature request to make PC\/Calm completely standalone so that it can be run anywhere - even on a VM in the cloud.<\/p>
