Mongod Database Repair __ Database

To view the Mongodb.log log, the following statement is found in the log:
..............
Mon Mar 317:46:37 [conn148] Assertion:10295:getfile (): Bad file number value (corrupt db?): Run Repair
..............
Translated as: declaration: GetFile (): Incorrect file value (corrupted database. ): Run Repair

After checking the MongoDB documentation, the process is repaired using the following methods:

First stop the Mongod service, delete the Mongodb.log, or you can back up
# Rm-rf/data/mongodb/mongodb.log

Delete a MongoDB process file
# Rm-rf/mongodb/mongod.lock

To repair
#/usr/local/mongodb/bin/mongod--repair--dbpath/mongodb/--repairpath/mongodb/repair/
Temporary repair directory must be large, or there will be insufficient disk capacity to prompt, unable to repair

At this time the MONGODB process will be stored in the/mongodb/repair/directory temporary repair database files, the file directory is "$tmp _repairdatabase_0" so this directory space is large enough.
Production environment database is 100G, repair carried out for about 3.5 hours, in the "/mongodb/repair/$tmp _repairdatabase_0" directory generated nearly 30G of database temporary files, repair completed after the database temporary files automatically purged.

After opening the Mongod service, check the database, read and write normal, Mongodb.log no error occurred. Fix OK.
