I am using mongodb with the webserver.

Recently, I observed that mongod server crashed after "no space left" for journalling.

So, after some online help I could repair and restart the DB.

But for production, I am worried now.

Is there a way in mongodb to truncate the journal files and prealloc files to get truncated without restart of mongodb or any other manual intervention.

For this question, please assume I am bound to 1 machine.

Is there a way in mongodb - when bound to one machine - to truncate the journal files and prealloc files to get truncated without restart of mongodb or any other manual intervention?
