Mongodb 副本集状态显示 "RECOVERING"

Question

我已经在 3 个 mongo 服务器上设置了副本集并导入了 5 GB 数据。现在辅助服务器的状态显示“RECOVERING”。您能否让我知道“RECOVERING”的含义以及如何解决此问题。

状态如下

rs.status()
{
    "set" : "kutendarep",
    "date" : ISODate("2013-01-15T05:04:18Z"),
    "myState" : 3,
    "members" : [
        {
            "_id" : 0,
            "name" : "10.1.4.138:27017",
            "health" : 1,
            "state" : 3,
            "stateStr" : "RECOVERING",
            "uptime" : 86295,
            "optime" : Timestamp(1357901076000, 4),
            "optimeDate" : ISODate("2013-01-11T10:44:36Z"),
            "errmsg" : "still syncing, not yet to minValid optime 50f04941:2",
            "self" : true
        },
        {
            "_id" : 1,
            "name" : "10.1.4.21:27017",
            "health" : 1,
            "state" : 1,
            "stateStr" : "PRIMARY",
            "uptime" : 86293,
            "optime" : Timestamp(1358160135000, 18058),
            "optimeDate" : ISODate("2013-01-14T10:42:15Z"),
            "lastHeartbeat" : ISODate("2013-01-15T05:04:18Z"),
            "pingMs" : 0
        },
        {
            "_id" : 2,
            "name" : "10.1.4.88:27017",
            "health" : 1,
            "state" : 3,
            "stateStr" : "RECOVERING",
            "uptime" : 86291,
            "optime" : Timestamp(1357900674000, 10),
            "optimeDate" : ISODate("2013-01-11T10:37:54Z"),
            "lastHeartbeat" : ISODate("2013-01-15T05:04:16Z"),
            "pingMs" : 0,
            "errmsg" : "still syncing, not yet to minValid optime 50f04941:2"
        }
    ],
    "ok" : 1

“RECOVERING”副本集节点上的消息意味着这些节点仍在执行初始同步。这些节点在转换到辅助状态之前不可读取。

初始同步有几个步骤。
