A method for deleting files from read cache for tape file system

An improved data processing apparatus and method and more specifically to mechanisms for caching data for a linear tape file system.

Disclosed is a method for caching data for a linear tape file system (LTFS).

There is a method for using a tape medium (a tape cartridge or medium) via a file system as if the tape medium is a HDD or a USB memory.

LTFS refers to both the format of data recorded on magnetic tape media and the implementation of specific software that uses this data format to provide a file system interface to data stored on magnetic tape. The LTFS format is a self-describing tape format developed by International Business Machines (IBM) Corporation of Armonk, New York to address tape archive requirements. The LTFS Format specification defines the organization of data and metadata on tape, where the files are stored in a hierarchical directory structure. Data written in the LTFS Format can be used independently of any external database or storage system allowing direct access to file content data and file metadata. This format makes it possible to implement software that presents a standard file system view of the data stored in the tape media. This file system view makes accessing files stored on the LTFS formatted media similar to accessing files stored on other forms of storage media such as disk or removable flash drives. Because tape medium is a sequential access device, random data...
