Fellas,

We have a MongoDB Cluster (3 node) setup in our QA with 375 GB storage. One of the DB is using almost 365 GB, so the team decided to clean it up. Somehow they are having issues and they asked me to just drop it and I complied (using the drop database command). After the successful drop, the DB is gone and  it can't be seen from the "show dbs" command in the shell. However the space didn't got free'd from the cluster. Somehow something still holding up 365 GB of storage in there. 

Am I missing something here??

Thanks

Vikram
