MooseFS (GPLv2) is an open-source version of MooseFS targeting open-source community. It's natural continuation of previous MooseFS editions.
MooseFS is a key system for Gemius / Core Technology in-house operations. We currently store over 3.6 PB of data, processing more than 150 000 events per second, every second, 24/7. The system is so crucial, that we do not allow anyone outside of our own development team to make changes in the structure of the code used by us.
Therefore our philosophy was to give this superb tool to everyone that would like to use it. We never aimed to create developers community - although your ideas, bug reports and wishes were carefully taken into account by our own developers. You can also send us comments and patches - but it does not mean we will include those in the main source code.
