PRIMECLUSTER Global File ServicesConfiguration and Administration Guide 4.1(Solaris Operating Environment)Edition December 2004

PrefaceThe Global File Services File System and its optional products are generically called "GFSproduct" or "GFS" in the document.This manual explains the functions, settings, and operations of the entire GFS products.For the available functions, refer to the installation guide of each GFS product.Target ReadersThis manual is intended for all the users operating the products with GFS File System (e.g.PRIMECLUSTER.)To read this manual, readers will require a general knowledge of the UNIX and Solaris(TM)Operating Environment. (From here, it will be abbreviated as “Solaris OE.”).Because GFS File System uses the functions of PRIMECLUSTER, readers will also needknowledge of cluster control as used in a PRIMECLUSTER system.Because GFS File System uses the functions of PRIMECLUSTER Global Disk Services,readers will also need knowledge of shard volume as used in a PRIMECLUSTER Global DiskServices.OrganizationThis manual consists of the following chapters and appendixes:Because GFS File System uses the functions of PRIMECLUSTER, readers will also needknowledge of cluster control as used in a PRIMECLUSTER system.Part 1 Overview of Global File ServicesChapter 1 Overview of GFSThis chapter explains overview of Global File Services file system.Part 2 GFS Local File SystemChapter 2 GFS Local File SystemThis chapter explains the functions and facilities of the GFS Local File System.Chapter 3 Structure of the GFS Local File SystemThis chapter explains the structure of the GFS Local File System.Chapter 4 Management of the GFS Local File SystemThis chapter explains the procedure for managing the GFS Local File System andthe basic commands that are used for management.Chapter 5 Backing Up and Restoring the GFS Local File SystemThis chapter explains how to back up and restore the GFS Local File System.Chapter 6 Commands in the GFS Local File SystemThis chapter describes commands for use by general users, which are provided bythe GFS Local File System.Chapter 7 Managing Restriction of GFS Local File System UsageThis chapter explains the quota functions used to limit file systems usage.Chapter 8 Defragmenting GFS Local File SystemThis chapter describes the defragmentation function provided by the GFS Locali
