We have been using MongoDB for a few weeks. One thing we could not understood is Pre-allocated file. Is there any way to check whether the pre-allocated file is currently used by MongoDB or not?
We have planned to implement "Quota File". So we need to ensure the pre-allocated file is currently used or not.
For Example, I have the database file as follows:
sgserver.0 ---> 16MB sgserver.1 ---> 128MB sgserver.2 ---> 256MB sgserver.3 ---> 512MB
How do I check the pre-allocated file
sgserver.3 is used by MongoDB (for example, this database is used by any BSON or its Un-used)?
