Abstract
A distributed snapshot in a distributed storage system is described, where the storage controller functions of the distributed storage system are separated from that of distributed storage system storage media. In an exemplary embodiment, a storage controller server receives a request to create the snapshot in the distributed storage system, where the distributed storage system includes a plurality of virtual nodes and a plurality of physical nodes, and the source object includes a plurality of stripes. The storage controller server further determines a set of virtual nodes from the plurality of virtual nodes, where each of the set of virtual nodes owns one of the plurality of stripes of the source object. For each of the set of virtual nodes, the storage controller server sends a clone request to that virtual node, where the request is to create a snapshot for the stripe hosted by that virtual node.
