我正在尝试扩展我的集群，并在UI中接收这个错误

预扩展集群测试失败。错误:Failed to start foundation service to do network validation SSD tier on nodes [u'xx.xx.xx. xx.]xx”,u 'xx.xx.xx。Xx ']的大小不能适应集群上预期的元数据增长。详情请参阅KB-8842。集群中有1个节点。不支持2节点以下的集群扩展

KB-8842 -我运行了KB-8842中列出的测试，没有得到任何错误。仅与集群扩展无关的警告。

它声明了这一点，并且看起来ssd很小。

使用上述输出中获得的数据，查找SSD层最小的节点，特别是在严重倾斜的集群中。为了维持集群的增长，在较小的节点中确定ssd的大小是非常重要的。

我正在尝试安装ce-2020.09.16，它已经安装成功，但我无法扩展集群。

我有3个配置完全相同的服务器。

ssd = 430 gb
hhd - 5TB x 3(数据)

问题是:

由于错误是关于SSD的大小，什么是这个配置的SSD的正确大小

是否有一个规模矩阵是支持的某处在线?

    I am trying to expand my cluster and receiving this error in the UI\u00a0<\/p>

    Failure in pre expand-cluster tests. Errors: Failed to start foundation service to do network validation SSD tier on nodes [u'xx.xx.xx.xx', u'xx.xx.xx.xx'] is not sized to accomodate expected metadata growth on cluster. Refer KB-8842 for more details. Cluster has 1 nodes. Cluster expansion from less than 2 nodes not supported<\/p>

    \u00a0<\/p>

    KB-8842 - i run the test outlined in kb-8842 and do not get any errors. Only warnings not related to the cluster expansion.<\/p>

    It states this and it appears that the ssd is to small.<\/p>

    Using data obtained in the preceding output, look for the nodes with the smallest SSD tier, especially in a heavily skewed cluster. In order to sustain cluster growth, sizing of the SSDs in smaller nodes is of utmost importance.

    I am trying to install ce-2020.09.16, and it has installed successfully but i can not expand the cluster.<\/p>

    I have 3 servers with the exact same configuration.<\/p>

    ssd = 430GB

    \u00a0<\/p>

    The question is:<\/p>

    Since the error is\u00a0concerning the size of the SSD, What is the correct sizing of the SSD for this configuration<\/p>

    Is there a sizing matrix that is supported somewhere\u00a0online?<\/p>

    @Joe方你好,

    这里是CE推荐的硬件规格的链接。

    希望这能回答你的问题。让我知道。

    嗨 @Joe方

    你检查过医生了吗 @Michael。勒•共享?

    我从你的帖子(集群有一个节点，不支持从少于2个节点的集群扩展)中了解到的是，你试图将一个CE单节点集群扩展到一个CE 3节点集群。

    如果这个说法是正确的，那么文档会说:

    • 使用冗余因子1创建Community Edition单节点集群。不能将现有的单节点集群扩展到三节点或四节点集群，从而自动创建冗余系数为2的集群。当您拥有一个单节点集群时，要扩展到一个三节点或四节点集群，请首先销毁集群，然后创建新的集群。看到摧毁一个集群．

    所以我担心你应该破坏单节点集群，然后创建一个新的三节点集群

    的问候!

    Hi @Joe Fong<\/user-mention>\u00a0<\/p>

    \u00a0<\/p>

    Have you checked the doc that @Michael.Manuele<\/user-mention>\u00a0shared?<\/p>

    \u00a0<\/p>

    What i understood from your post (cluster has one node, Cluster expansion from less than 2 nodes not supported)\u00a0is that you are trying to to expand a CE single node cluster to a CE three node cluster.\u00a0<\/p>

    \u00a0<\/p>

    If that statement is correct the docs says:<\/p>
