我已经在3 mongo服务器上设置了副本集并导入了5 GB数据.现在显示"RECOVERING"的辅助服务器的状态.你能让我知道"恢复"的方法是什么以及如何解决这个问题.

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, …

我们已经在新服务器上移动代码,因为之前我们使用的是tomcat6但是在新系统上安装了tomcat7.所以我们得到以下错误,我做谷歌搜索并进行更改,但仍然得到相同的错误.错误如下.
