Here is a link to a talk given by John Mark Walker at this year’s LinuxCon Japan, in which he discusses some of the internal details of the Gluster 3.3 release.

A few of the new features discussed during the presentation are:

• UFO (universal file and object storage)
• HDFS compatibility
• Proactive self-heal
• Granular locking
• Quorum enforcement (for resolving split-brain scenarios)
