Did you ever tried huge installations? 3PB, 100mln of files?

Your choice. I don't have problem with that, but please don't be against us.

So you shouldn't say bad words about MooseFS. We test LizardFS (and others - like Ceph, Gluster etc.) on regular basis.

I understand that it is time-consuming, but I hope that you will find time in the future and give it a try.

Thanks a lot. This is very helpful, we will check that. I remember porting to official freebsd ports - PITA, but what to do. There are rules and we (developers) should obey them.

Thanks for saying that, because at the beginning I had a feeling that you are against us.

We are still making this solid foundation (i hope :) ).
