Open Source Gluster 3.3 Melds Object and File Storage

Gluster 3.3 also provides improvements that make the system more resilient and scalable. Among those improvements are a series of self-healing additions including something known as granular healing. Walker explained that with granular healing, the self-heal process goes block by block on each file to be healed to determine which parts of the file to heal.

“Before this release, you risked service outages while your large, multi-GB VM image recovered from a failure,” Walker said. “In those bad old days, the entire VM would be locked while a self-heal took place. No more.”
