Abstract
A distributed storage system stores a storage volume as segments that are allocated as needed and assigned VSIDs according to a monotonically increasing counter. The storage volume may be provisioned by an orchestration layer that manages the storage volumes as well as containers executing executable components of the storage volume. The storage volume may be replicated, such as by replicating slices of the storage volume. A primary copy of the slice may be moved from one node to another within the distributed storage system by designating it as a replica, creating a new replica at the new location which is then brought current. The new replica is then designated as the primary replica and the former primary replica may be deleted. A non-replicated storage volume may be converted to a replicated storage volume and vice versa.
