阻止容错问题？

大家好，

我想问一些问题。

我有1365G6，然后将有两个8235G7和一个8135G7。

当所有8000加入1365时，总共将有4个块和8个节点。

如果我启用块容错的能力，则如何计算可用空间？

启用块容错后，我可以删除两个8000并将其重新安装为备用群集？还是可以将容错域返回到节点？

谢谢

Hello Wei,<\/p>

\u00a0<\/p>

The block awareness feature doesn\u2019t effect available space calculation at all. You should refer to KB article\u00a01557 for guidance on calculating the useable storage space on your cluster.<\/p>

\u00a0<\/p>

When you remove the two\u00a08235G7, your cluster will only have two blocks remaining and so it won\u2019t be able to maintain block level fault tolerance. At that point the cluster just go into a standard node based fault tolerance.<\/p>","className":"post__content__best_answer"}">

Hi Everyone,<\/p>

I want to ask some\u00a0questions.<\/p>

I have 1365G6 ,\u00a0and then there will be two 8235G7 and one 8135G7.<\/p>

When all 8000 join 1365, there will be a total of 4\u00a0blocks and a total of 8 nodes.<\/p>

If I enable BLOCK FAULT TOLERANCE, how to calculate the available space ?<\/p>

\u00a0<\/p>

After enable BLOCK FAULT TOLERANCE can I remove the two 8000s and reinstall them as a backup cluster?? Or can it return fault tolerance domain to nodes?<\/p>

你好魏，

块意识功能根本不会影响空间计算。您应该参考KB第1557条，以获取有关计算群集上可用存储空间的指南。

当您删除两个8235G7时，您的群集只剩下两个块，因此它将无法维持块级别的容错。那时，群集只进入基于标准节点的容错。

嗨，塞德，

如果我在同一机架中安装了8个节点的5个块，您是否建议您继续使用RF = 2或3，或者您会使用错误公差域来阻止？

谢谢

Hi Sedward,<\/p>

If I\u00a0have 5 blocks with 8 nodes installed in the same rack,\u00a0will you recommend to keep using RF = 2 or 3, or will you use fault tolerance domain to block instead?<\/p>

Thank you<\/p>","quoteUsername":"Wei Cheng","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">

我想，如果您有支持它的硬件，我将始终尝试启用块容错。您应该参考此文档以获取有关这些设置的更多信息：
