大家好！

我想问几个问题。

我有1365G6，还有两个8235G7和一个8135G7。

当8000全部加入1365时，总共将有4个块，总共8个节点。

如果我启用块容错，如何计算可用空间?

启用块容错功能后，我能否将两个8000作为备份集群移除并重新安装??或者可以将容错域返回给节点?

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,

块感知特性根本不会影响可用空间的计算。关于计算集群上的可用存储空间，您应该参考KB文章1557。

当您删除两个8235G7时，您的集群将只剩下两个块，因此它将无法维持块级别的容错。此时，集群就进入了基于标准节点的容错模式。

嗨Sedward,

如果我有5个block, 8个node安装在同一个机架上，你会建议继续使用RF = 2还是3，还是使用容错域来block ?

谢谢你！

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"}}}">

如果你有硬件支持，我想我会一直尝试启用块容错。有关这些设置的更多信息，请参考本文档:
