我在备份副本集时遇到问题mongodump。mongoexport只是出于好奇验证了同样的问题。

这是我的设置：

  • mongodb-linux-x86_64-static-legacy-2.2.0
  • 3个节点副本集（截至目前健康）
PRIMARY> rs.status() {
        "set" : "eu-int",
        "date" : ISODate("2013-03-01T09:54:06Z"),
        "myState" : 1,
        "members" : [
                {
                        "_id" : 0,
                        "name" : "ldnpsr1971:27017",
                        "health" : 1,
                        "state" : 1,
                        "stateStr" : "PRIMARY",
                        "uptime" : 26646,
                        "optime" : {
                                "t" : 1362131645000,
                                "i" : 11
                        },
                        "optimeDate" : ISODate("2013-03-01T09:54:05Z"),
                        "maintenanceMode" : -1,
                        "self" : true
                },
                {
                        "_id" : 1,
                        "name" : "ldnpsr1723:27017",
                        "health" : 1,
                        "state" : 2,
                        "stateStr" : "SECONDARY",
                        "uptime" : 26646,
                        "optime" : {
                                "t" : 1362131645000,
                                "i" : 8
                        },
                        "optimeDate" : ISODate("2013-03-01T09:54:05Z"),
                        "lastHeartbeat" : ISODate("2013-03-01T09:54:05Z"),
                        "pingMs" : 0
                },
                {
                        "_id" : 2,
                        "name" : "ldnpsr2114:27017",
                        "health" : 1,
                        "state" : 2,
                        "stateStr" : "SECONDARY",
                        "uptime" : 26641,
                        "optime" : {
                                "t" : 1362131645000,
                                "i" : 11
                        },
                        "optimeDate" : ISODate("2013-03-01T09:54:05Z"),
                        "lastHeartbeat" : ISODate("2013-03-01T09:54:06Z"),
                        "pingMs" : 0
                }
        ],
        "ok" : 1 }

现在我正在导出：

~/mongo/bin/mongodump --host "eu-int/ldnpsr1971:27017,ldnpsr1723:27017,ldnpsr2114:27017" --db msgstore --collection forJames --out ~/data/mongo-backup/eu-int/20130301

死于：

仅指定单个节点（副本集的 PRIMARY 节点）执行相同的命令会成功创建转储。

请问有人知道我做错了什么吗？

您遇到了 MongoDB 错误https://jira.mongodb.org/browse/SERVER-7006，该错误发生在 2.2.0 中，但在 2.2.3（最新生产版本）中已修复。

升级应该可以解决问题。
