Preface

Advanced File System (AdvFS) is the default file system for the Compaq Tru64^TM UNIX^® (formerly DIGITAL UNIX) operating system. It provides rapid crash recovery and a flexible structure that allows you to manage your file system while it is on line.

AdvFS Utilities is a layered product that extends the file system capabilities by including utilities to add volumes, create clones, stripe files, and balance file domains. AdvFS Utilities also includes a graphical user interface (GUI) to simplify AdvFS management.

This guide describes AdvFS and AdvFS Utilities in detail. It provides information on features and functions, and it gives suggestions on how to use these functions. Many functions can be accomplished through either the command line or GUI. The AdvFS GUI provides online help for completing specific procedures.
