Question

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

这是我的设置：

的mongodb-Linux的x86_64的静电遗留-2.2.0
3个节点副本集（当时正在健康）

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 }

现在我正在进行导出：

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

哪个死了：

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。

请有人知道我做错了吗？

您遇到了发生在2.2.0中的MongoDB错误https://jira.mongodb.org/browse/SERVER-7006，但修复了2.2.3（最新生产版本）。

升级应解决问题。

Mongo导入/转储不能与副本集一起使用
