First, keep in mind that just because there is not an official maintenance release does not necessarily mean that the latest feature release is wildly unstable. There is a significant amount of testing that is performed for each Lustre release, and there are a lot of people using Lustre in production who have a vested interest in making sure Lustre will work. The lack of a maintenance release should not cause you to immediately jump ship for another file system. IMHO, if you need a free scalable parallel file system, Lustre is still your best choice. With that being said, I wish I could give you a clearer picture of where Lustre maintenance releases are headed. That is a question I am also very interested in. Maybe we will see option #3: Community members publish lists of patches they are running in production. If a large site is running a Lustre 2.7 file system and has applied a set of patches they think makes it sufficiently stable, maybe small sites could use Lustre 2.7.0 + (list_of_big_site_patches) as an informal 2.7.1 release. The balance between features and stability is a complex topic, but it is one that Lustre developers care about.
