副本集配置无效或我们不是它的成员,在kubernetes中运行

Question

我从这里发布了这个问题

我在kubernetes环境中运行分片mongodb,有3个分片,每个分片上有3个实例.出于某些原因,我的mongodb实例已被重新安排到另一台机器上.

问题是当一个mongodb实例被重新安排到另一个实例时,replica config它将被无效.导致此错误如下.

            > rs.status()
            {
                "state" : 10,
                "stateStr" : "REMOVED",
                "uptime" : 2110,
                "optime" : Timestamp(1448462710, 6),
                "optimeDate" : ISODate("2015-11-25T14:45:10Z"),
                "ok" : 0,
                "errmsg" : "Our replica set config is invalid or we are not a member of it",
                "code" : 93
            }
            >

这是配置

            > rs.config().members
            [
                {
                    "_id" : 0,
                    "host" : "mongodb-shard2-service:27038",
                    "arbiterOnly" : false,
                    "buildIndexes" : true,
                    "hidden" : false,
                    "priority" : 1,
                    "tags" : {

                    },
                    "slaveDelay" : 0,
                    "votes" : 1
                },
                {
                    "_id" : 1,
                    "host" : "shard2-slave2-service:27039",
                    "arbiterOnly" : false,
                    "buildIndexes" : true,
                    "hidden" : false,
                    "priority" : 1,
                    "tags" : {

                    },
                    "slaveDelay" : 0,
                    "votes" : 1
                },
                {
                    "_id" : 2,
                    "host" : "shard2-slave1-service:27033",
                    "arbiterOnly" : false,
                    "buildIndexes" : true,
                    "hidden" : false,
                    "priority" : 1,
                    "tags" : {

                    },
                    "slaveDelay" : 0,
                    "votes" : 1
                }
            ]

以及 db.serverStatus()重新安排的mongodb实例的示例

            > db.serverStatus()
            {
                "host" : "mongodb-shard2-master-ofgrb",
                "version" : "3.0.7",
                "process" : "mongod",
                "pid" : NumberLong(8),

我希望我有意义..因为,我很快就会在现场制作中使用它...谢谢!!
