1. A method, comprising: selecting a first range of object identifiers to use by a first storage cluster for identifying volumes hosted by the first storage cluster; storing the first range of object identifiers within a first volume location database; evaluating object identifiers, currently assigned by the first storage cluster to volumes hosted by the first storage cluster, with the first range of object identifiers; generating a new object identifier for a current volume hosted by the first storage cluster based upon a current object identifier of the current volume being outside the first range of object identifiers; creating a mapping data structure to map the current object identifier to the new object identifier; storing the mapping data structure within the first volume location database for referencing the current volume using the new object identifier; sending a message to a second storage cluster of the first range of object identifiers; and instructing the second storage cluster to select a second range of object identifiers that does not overlap the first range of object identifiers.
