解决了

2个不同的服务器上的两个SSD故障(单SSD)


大家好,我只是对这种情况很高兴,



我有3个带有单个SSD的服务器类型2310,

因此,如果SSD同时在2个不同的服务器上失败,将会发生什么?

如果这是一个三个节点群集,而您丢失了两个SSD,那么简短的答案是群集将失败。当您松开一个SSD时,它将重建其存储在其他两个SSD上以保持弹性状态。如果您丢失了另一个SSD,则不足以维持群集的弹性,所有存储I/O都会失败,因为CVM实际上生活在SSD上。该管理程序居住在Satadom或M.2驱动器上,具体取决于您一代的硬件。您会失去两个SSD,不仅要查看数据丢失,还要查看完整的存储I/O通信暂停。

是的,先生,先生,

我使用联想用于服务器,问题是2个不同节点故障的2个SSD。

因此,我们丢失了数据。



在与联想团队讨论之后,我们从一开始就使用2个节点对每个节点进行了重建,因此SSD可以相互纠正以获取MIIMIMALISM损失数据。



结论 :


  • 如果您尝试购买3个节点服务器,请确保每个节点都有2个SSD用于最低段损失数据
  • 使用第三方备份程序来确保您的数据安全。
