UNIX Filesystems: Evolution, Design, and Implementation

Disk-Based Filesystem Case Studies

This chapter describes the implementation of three different filesystems: the VERITAS Filesystem, VxFS, has also been ported to many versions of UNIX and has been the most successful of the “commercially” available filesystems; the UFS filesystem, first introduced in BSD UNIX as the Fast File System, has been ported to most versions of UNIX; with the proliferation of Linux systems, the ext2 filesystem and its successor ext3 are widely known and have been documented extensively.
