Mongo filled up the disk with data and crashed, how to unload its data?

Question

MongoDB

There are 150mb left on the server, it will not work to start mongo, what should I do?

Answer 1

* Run in --smallfile mode, where monga doesn't reserve space
* Try rebooting the server (the old version of mongi created a lot of temporary files)
* Expand disk
* Download mongi files over the network and run on the same version on another machine

Answer 2

Alternatively, add a second disk, merge partitions from two disks into one large one, start mongo.
