Increasing Efficiency of Block-Level Processes Using Data Relocation Awareness

A computer program product comprising a computer readable storage medium having a computer readable program stored therein, wherein the computer readable program, when executed on a computing device, causes the computing device to:

• responsive to detecting an I/O write to a storage volume, determine 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;
• responsive to the I/O write matching one or more suspicious I/O reads in the plurality of suspicious I/O reads, identify that there is a data relocation associated with the sector associated with the I/O write;
• inform 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
• release each sector associated with the one or more suspicious I/O reads in a file system for reuse.

An apparatus, comprising:

• a processor;
• and
• a memory coupled to the processor, wherein the memory comprises instructions which, when executed by the processor, cause the processor to:
• responsive to detecting an I/O write to a storage volume, determine whether the I/O write matches one or more suspicious L/O reads in a plurality of suspicious I/O reads previously recorded in a memory;
• responsive to the I/O write matching one or more suspicious I/O reads in the plurality of suspicious I/O reads, identify that there is a data relocation associated with the sector associated with the I/O write;
• inform 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
• release each sector associated with the one or more suspicious I/O reads in a file system for reuse.
