Maintaining reserved free space at the end of a physical volume for creating new segments of segmented logical volumes in the reserved free space

摘要

A storage manager application implemented in a first computational device maintains a virtual logical volume having a plurality of segments created by the storage manager application, wherein space is reserved at the end of a physical volume corresponding to the virtual logical volume, and wherein the physical volume comprises a linear storage medium. A request is received to write data, at the first computational device, from a second computational device. The data is written to the reserved space, wherein the writing of the data causes new segments to be created in the reserved space.
