你好，

在平台管理指南中，一次只能有1个节点故障。
如果一个完整的块丢失会发生什么？

谢谢，最好的问候

\nif you have 4 nodes per block, a single block failure will mean you hvae 4 nodes down therefore you will likely experience storage unavailability.
\n
\nif you have rf=3 containers, you can sustain a two node outage.
\nhowever, similar math applies.
\n
\nthis is why we offer power supply redundancy per block so you should only experience complete block failure in rare circumstances.","className":"post__content__best_answer"}">

    \nin the platform admin guide is mentioned that there can be only 1 node failure at one time.
    \nWhat happens if a complete block get's lost?

    猜测这是一个取决于问题。如果您有5个节点，则可以将群集配置为用RF3丢失2个节点。如果您有3个统一块，并且损失了一个块，则群集将继续运行。该功能称为可用性域。


    如果您只有1个街区，并且会失去电源，那么一旦恢复电源，一切都应该恢复正常。所有写作都是同步的，并将其知识与猜测VM相关。

    这有帮助吗？

    \nIf you only have 1 block and you lose power to the block, once you restore power everything should come back fine. All writes are synced and knowledged to the guess vms.

    如果您的RF = 2容器，则只能在群集中维持单个节点中断。
    如果您的每个块有4个节点，则单个块故障将意味着您将4个节点降低，因此您可能会遇到存储不可用的情况。

    如果您的RF = 3个容器，则可以维持两个节点中断。
    但是，适用类似的数学。

    这就是为什么我们每个块提供电源冗余，因此您只能在极少数情况下经历完全的块故障。

    感谢您的信息。
    是否可以获得两个机架“ Rack Aware”配置？（考虑50％的计算预订）

    值得指出的是，尽管群集一次只能处理1（或较高的RF设置）节点故障，但您可能会失去节点＃1，并且群集将开始愈合。完成该过程后，您可能会丢失另一个节点并仍在运行。如果您损失的节点比RF设置损失更多的节点，则只有在群集治愈之前发生故障时可以处理的节点。如果您丢失了一个障碍，那不是很有帮助，但是对于仅影响1个节点（例如HDD或BAD RAM）的东西，您就可以了。
