Iam not the right person to answer you if there will be EC in CE edition, but i know that it is not implemented in current MFS 3.x CE, neither metadada high availability. And missing metadata HA is currently spof and the biggest disadvantage (for me) and reason why im will be deploying and testing CEPH. (i tried to get a quotation twice, but with no answer from their business dpt... iam not blaming) MFS is great and rock solid piece of software. In our company we are using it since MFS 2.x |

I use snapshots as you would Mac Time Machine. Imagine I have some important files and I accidentally deleted them. Another very useful property of snapshots is a quick copy of massive folders Please consider utilisation of your storage will raise - the chunks are only deleted when the last snapshot they are in is deleted. |

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?
