Abstract
Space sharing between logical volumes is achieved through a technique that enables available storage space to be flexibly consumed and released by the logical volumes. Each logical volume is associated with an address tree that defines how available storage space is consumed by the logical volume. The technique involves receiving an input/output (I/O) operation that specifies a logical address within an address tree associated with the logical volume, parsing the address tree to identify an entry therein, if any, that is associated with the logical address, where the entry stores physical address information that is associated with the logical address. If it is determined that the entry exists, then one or more translated I/O operations are generated based on the physical address information and forwarded to a physical device manager to carry out the translated one or more I/O operations.
