resolve-virtual-oids

Description

The resolve-virtual-oids command takes one or more Virtual OIDs and uses one or more object maps to resolve each Virtual OID to one or more block addresses. It can also be used to programatically check whether a given Virtual OID maps to a given block address, or do such checks in a batch — that is, check whether a specific set of Virtual OIDs maps directly to a specific set of block addresses.
