Checking records consistency after mongorestore --noobjcheck
You can run a --repairDatabase for that node:

mongod --repair --repairpath &lt;repair_path&gt;


Keep in mind that the repair path should have at least as your data size free disk space. (if you have 100GB, the repair path should have at least 100GB free also.
That should take care of problems of that sort.

Also, in the future if anything of some sort happen again and you need to run mongodump, you can run the mongodump --repair.
This will ensure that any corrupted data will not be dumped.

Hope this helps
