Abstract
A technique that provides the ability to copy or move a volume that includes one or more quota structures, by using logical replication, where the volume and any quota structures in it are immediately accessible upon completion of the copy/move operation, and where the quota structures' usage control functionality is immediately functional and reliable upon completion of the copy/move operation. A user does not have to reinitialize the quota mechanism or invoke a quota scanner at the destination.
