SYSTEM AND METHOD FOR TRANSPARENT RECOVERY OF DAMAGED OR UNAVAILABLE OBJECTS IN A REPLICATED OBJECT STORAGE SYSTEM

摘要

A redundant array of independent nodes are networked together. Each node executes an instance of an application that provides object-based storage. The nodes are grouped into a plurality of systems each having multiple nodes. An object recovery method comprises: receiving, by a first system a client application, a read request for an object, the object having been replicated to/from at least one second system; if the object of the read request is available in the first system, returning by the first system the object of the read request to the client application; and if the object of the read request is not available in the first system, performing a read from replica process by the first system to access a replica of the object from a second system among the systems and using the replica to return the object of the read request to the client application.
