这篇文章给大家分享的是有关MongoDB副本集分片集群一分片config库主机断电导致该分片config库无法启动怎么办的内容。小编觉得挺实用的,因此分享给大家做个参考,一起跟随小编过来看看吧。
由于机房意外断电,一分片config服务器断电导致该config库无法启动,相关报错如下:
关键报错信息:
2018-01-22T15:18:43.863+0800 I -[initandlisten] Detected data file in D:/mongodata/cfg created by the 'wiredTiger' storage
engine,so setting the active storage engine to 'wiredTiger'.
2018-01-22T15:18:43.865+0800 W- [initandlisten] Detected unclean shutdown -D:/mongodata/cfg/mongod.lock is not empty.
2018-01-22T15:18:43.866+0800 w STORAGE [initandlisten] Recovering data from the last clean checkpoint.
根据网上查到的处理方法:
1、关闭启动窗口
2、删除D:/mongodata/cfg/mongod.lock,
3、执行修复操作:D:/MongoDB/Server/3.2/bin/mongod –configsvr –replSet configReplSet –port 27001
–dbpath D:/mongodata/cfg –repair

4、修复操作没有明显的报错,重新启动config库,问题依然存在,报错与上述提到的日志一致
由于是副本集分片集群,且该config库只是一个片的config库,该副本集分片集群一共有3台config库,于是决定删除该config库
的data目录D:/mongodata/cfg下的所有数据文件以从集群其他节点重新同步,该config库重新同步数据后恢复正常。
