How do I resolve those.

Answer 1

It looks like you have to repair your DB.

To do so.

• Create a backup of the data files.

Create a backup copy of the data files in the --dbpath.

• Start mongod with --repair.

To repair the data files, start the mongod instance with the --repair option. By default, during the repair operation, MongoDB uses a _tmp directory in the --dbpath.

If the mongod instance uses MMAPv1 Storage Engine, you can include the --repairpath option to specify an alternate temporary directory. For details, see --repairpath.

Issue a command similar to the following:

mongod --dbpath /data/db --repair
 

Upon completion, the dbpath should contain the repaired data files and an empty mongod.lock file
