Mogno Returned Empty upon Server Restart

[Dimitris Papaevagelou]

I recently restarted my whole server (gracefully) due to some cpu problems and all of my dbs returned empty.

Does anyone knows how to restore my lost data?

Although this http://docs.mongodb.org/manual/tutorial/recover-data-following-unexpected-shutdown/ is very helpful it didn't work for me.

Here are some logs

Are you sure it started with the same dbpath as before? The startup looks like it found an empty database path. What's in the dbpath directory /var/lib/mongo?
