Question

我们有两个分区的演员服务。所有空闲辅助副本都处于警告状态，并显示Service Fabric Explorer中的以下消息：

Unhealthy event: SourceId='System.RA', Property='ReplicaOpenStatus', HealthState='Warning', ConsiderWarningAsError=false.
Replica had multiple failures during open on _cp_3. API call: IStatefulServiceReplica.Open(); Error = System.ArgumentException (-2147024809)
An item with the same key has already been added.

从一个分区移动到两个分区时，我们首次遇到此错误。解除节点并删除数据是一个临时修复，因为问题在下一次部署时重新出现。

这个问题导致Service Fabric不断尝试启动服务，该服务只停留在＆＃34;开始，死亡，重复＆＃34;的永久循环中。

我知道处于IdleSecondary状态的副本意味着它当前正从其他节点获取数据，以便被提升为ActiveSecondary。在我看来，问题与从演员的其他节点获取数据有关。

导致此问题的原因是什么以及如何在将来阻止它？

Answer 1

不支持重新分区ActorService。如果要增加分区数，则需要删除该服务，然后重新创建它。

当您说：“从一个分区移动到两个分区。”时，您能否共享有关您实际执行的Service Fabric操作的详细信息？
