阿耳忒弥斯从节点不会在整个集群中启动

我正在尝试将一个6节点的ApacheArtemis静态集群作为3个实时备份对运行。为了在整个集群重新启动过程中不丢失数据，我还创建了一种机制来确定这对节点中哪一个具有较新的数据，并在此基础上服务器自动决定启动该特定节点是否安全。在群集完全重新启动期间，服务器同时启动，具有较新数据的节点在最近充当备份的节点之前启动。

这种情况在使用单个实时备份对时可以完美地工作。

停机：

  1. 主节点处于活动状态，从节点处于备份状态
  2. 主节点=>从节点启用
  3. 从节点

开始：

  1. 两个节点都已死亡
  2. 从节点=>上线
  3. 主节点=>启用，从节点备份

但是，在6节点集群中，备份节点根本不会激活：

  1. 3个活动节点，3个备份节点；成对结合在一起形成单独的基团(rs1，rs2，rs3(
  2. 停止rs1主节点=>rs1从节点启用
  3. 停止rs1从节点
  4. 启动rs1从节点=>永不上线
  5. 由于潜在的数据丢失，不得启动rs1主节点

知道我的设置有什么问题吗？

上面显示了从机根本没有启动。

ActiveMQ Artemis使用复制时，活动服务器和备份服务器不共享相同的数据目录，所有数据同步都是通过网络完成的。

启动后，备份服务器将首先需要同步活动服务器中的所有现有数据，然后才能在出现故障时替换活动服务器因此，与使用共享存储时不同的是，复制备份在启动后不会是完全可操作的备份，而是只有在完成与实时服务器的数据同步后

为什么单个实时备份对看起来有效？

启动时的备份节点在SharedNothingBackupActivation执行以下步骤：

  • 初始化(看起来正在运行(
  • 正在等待群集连接(此处缺少(
  • 正在启动备份管理器

因此，在使用单个实时备份对的情况下，备份节点不会完成初始化。
