增量迁移失败报错，关键词“Timed out after 60000 ms while waiting for a server that matches com.mongodb.client.internal”

场景描述

MongoDB->DDS实时迁移场景，增量迁移报错，日志提示信息：service INCREMENT failed, cause by: [reason]:Failed to connect to database due to network, check the network between the DRS and the database or try again later.[message]:Timed out after 60000 ms while waiting for a server that matches com.mongodb.client.internal.MongoClientDelegate$1@27105e1a. Client view of cluster state is {type=REPLICA_SET, servers=[{address=***, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.ConnectException: Connection timed out (Connection timed out)}}, {address=***, type=UNKNOWN, state=CONNECTING, exception={com.mongodb.MongoSocketOpenException: Exception opening socket}, caused by {java.net.NoRouteToHostExceptio。

可能原因

  • 网络不稳定导致写入目标库时建立连接超时。
  • 目标库系统繁忙导致建立连接超时。

处理方法

  1. 检查目标库运行状态是否正常。
  2. 检查DRS迁移实例和目标库之间的网络是否存在丢包、重传等情况。
  3. 联系华为工程师调整默认的超时时间。
