Suresh headed today’s discussion on United-FS: A Logical File System Providing a Single Image of Multiple Physical File Systems on NFS Server. This was longer than the previous paper. We talked about some basics of cluster filesystems (like Lustre), RAID concepts, NFS, pNFS etc. Nikanth explained about the device-mapper and LVM, and how software raid could be implemented. Techniques used by United fs for reliability, performance, were discussed and also other ideas beyond those suggested by the authors were also debated.

Srinidhi also joined us today. Overall a good, high energy and fun session!

Nikanth led today’s _very_ active ~2 hour session. Basic snapshotting techniques were discussed, some possible variations on the ideas presented in the paper were also debated. We looked at dm snapshot, and some related code too. Nikanth and Suresh with their block layer and filesystem knowledge were very helpful in steering discussion.

On the whole it was very enjoyable 2 hours :-D
