Hello,

I just started playing around with MooseFS in one of my development environments and absolutely fell in love with it. From an experience perspective I have deployed multple Ceph and GlusterFS peta-scale clusters over the past six years. So my familiarity and comfort level with distributed filesystems is pretty high. I digress, while my initial experience with MooseFS has been very good, one glaring issue pops up and that is the lack of erasure code support makes it unusable in large scale deployments due to the massive waste of space caused by replication of data assigned via storage goals. While I'm new to MooseFS and haven't played around with the extensive configuration options for storage classes, not enabling or allowing EC in the free versions seems like "pricing yourself out of the market" against other open source distributed file systems. More to the point, are there any plans of adding erasure codes to the GPL version? Or better yet, am I simply missing something from the configuration options that would enable this feature?
