Question

我有两个节点“ A”（主要）和“ B”。每个节点有3个资源。在节点“ B”上，我替换磁盘，然后将每个资源添加为辅助资源。两种资源成功连接并同步，但是只有一种资源存在问题。当在节点“ B”上停止该资源时，节点“ A”显示

lv1 role:Primary
  disk:UpToDate
  b.host connection:Connecting

当我在节点“ B”上启动此资源时，节点“ A”显示：

lv1 role:Primary
  disk:UpToDate
  b.host connection:StandAlone

节点“ B”显示：

lv1 role:Secondary
  disk:Inconsistent
  a.host connection:Connecting

我会尝试一切，删除/添加资源，节点“ B”上的元数据，删除数据，重建RAID drbdadm connect lv1 --discard-my-data等。工作中断的资源之间的区别是This node was a crashed primary, and has not seen its peer since

有什么想法我可以解决吗？

Answer 1

在我的情况下，在节点“ A”（主）上，我有LVM，在节点“ B”上，我有MDRAID。这种差异使我在524272个行业中的资源规模有所不同。我要如何保存我的数据。我在主模式下运行这两个资源，将数据从“ A”装入并复制到“ B”，然后将节点“ A”重建到MDRAID并同步资源。

DRBD StandAlone具有新资源
