File System Properties Most files are small. ¾Need strong support for small files. ¾Block size can’t be too big. Some files are very large. ¾Must allow large files (bit file offsets). ¾Large file access should be reasonably efficient. Most systems fit the following profile: 1. Most files are small 2. Most disk space is taken up by large files. 6 3. CSE – Lecture File Systems 3. Disks and the OS.  Disks are messy physical devices: ◆ Errors, bad blocks, missed seeks, etc.  The job of the OS is to hide this mess from higher level software. ◆ Low-level device control (initiate a disk read, etc.) ◆ Higher-level abstractions (files, databases, etc.). File System Implementation. Inthischapter,weintroduceasimplefilesystemimplementation,known as vsfs (the Very Simple File System). This file system is a simplified version of a typical UNIX file system and thus serves to introduce some of the basic on-disk structures, access methods, and various policies that you will find in many file systems today.
