Abstract:
1. A method, in a data processing system, for increasing the efficiency of block-level processes, the method comprising: responsive to detecting an I/O write to a storage volume, determining whether the I/O write matches one or more suspicious I/O reads in a plurality of suspicious I/O reads previously recorded in a memory, wherein each suspicious I/O read in the plurality of suspicious I/O reads is identified by a previous I/O read on a sector in the memory which has no record indicating that the sector is available to be read; responsive to the I/O write matching one or more suspicious I/O reads in the plurality of suspicious I/O reads, identifying that there is a data relocation associated with the sector associated with the I/O write; informing a data relocation application of the data relocation of the sector associated with the one or more suspicious I/O reads associated with the sector indicated by the I/O write; and releasing each sector associated with the one or more suspicious I/O reads in a file system for reuse.
