2个不同的服务器上的两个SSD故障（单SSD）

F
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。
    If it's a three node cluster and you lose two SSDs the short answer is the cluster will fail. When you loose one SSD, it will rebuild it's stored extents on the other two SSDs to maintain a resilient state. If you lost another SSD, there isn't enough to maintain the cluster resilience all storage I\/O will fail because the CVM actually lives on the SSD. The hypervisor lives on the satadom or M.2 drive depending on your generation of hardware. You loose both SSDs and you're not only looking at data loss but complete Storage I\/O communication cessation.<\/content-quote>
    \r\nYes You Right Sir,
    \r\nIm Using Lenovo for the server and the problem is 2 SSD on 2 different Nodes failure.
    \r\nBecause Of that we lose our data then.
    \r\n
    \r\nAfter discuss with Lenovo team finally we rebuild from the start using 2 ssd for every nodes, so SSD can Redudant each other for miimalism loss data.
    \r\n
    \r\nConclusion :
    \r\n
      \r\n
    • If you try bought 3 nodes server make sure every nodes had 2 ssd for minimalism Loss Data \r\n
    • Using Third Party Backup Program for keep your data safe. \r\n<\/ul>","quoteUsername":"Felix.","translations":{"Common":{"like":"Like","unlike":"Unlike"},"Forum":{"Quote":"Quote","Share":"Share"}}}">
