1、關閉一直處於RECOVERING狀態的mongodb server
/opt/mongodb/mongodb-linux-x86_64-2.4.8/bin/mongo 127.0.0.1:22001
use admin
db.shutdownServer()
2、將原數據目錄改名，新建數據目錄，再啟動mongodb實例
mv /opt/mongodb/shard1/data /opt/mongodb/shard1/data_bak
mkdir /opt/mongodb/shard1/data
/opt/mongodb/mongodb-linux-x86_64-2.4.8/bin/mongod --shardsvr --replSet shard1 --port 22001 --dbpath /opt/mongodb/shard1/data --logpath /opt/mongodb/shard1/log/shard1.log --fork
3、查看恢復狀態，為STARTUP2
/opt/mongodb/mongodb-linux-x86_64-2.4.8/bin/mongo 127.0.0.1:22001
use admin
rs.status()
