Comment 2 for bug 1394864

Partitioning schema is located inside nailgun. Moving to fuel-python.

I filed this bug with fuel-python team already: https://bugs.launchpad.net/fuel/+bug/1393369

I've also partially mitigated this bug by reducing the verbosity of MongoDB logging[1] and rotating more frequently when running in Debug logging mode[2]

That having been said, it's quite possible to run out of disk space with only 16GB root partition. It only takes a few administrator commands to fill the disk up to 90% and then heavy user activity to push it to the limit.
