Abstract:
Various embodiments for defragmentation of a storage volume in a computing storage environment by a processor device are provided. A volume table of contents (VTOC) is serialized for a volume scan operation. At least one dummy data set in the storage volume is allocated, to be subsequently filled with actual data pursuant to a defragmentation operation. The serialization of the VTOC is released, allowing access to the storage volume. Input/output (I/O) operations are allowed to occur.
