System Administration: A Task Overview

The administration of DFS can be divided into three general types of tasks:

· Fileset Management: efficiently organizing the filesets in your cell and maintaining appropriate backup versions of filesets that contain binary and user files

· System Management and Configuration: monitoring the performance of the file system software and making adjustments as necessary

· Security Issues: establishing the correct procedures and policies to ensure the security of the file system

DFS provides the commands introduced in this section to help you with these tasks and procedures. Most DFS commands are divided into the following categories, or command suites:

bak
The bak command suite is used to copy files from the file system to a backup tape and to restore them from tape to the file system, as necessary. System administrators issue bak commands to operate the DFS Backup System; users do not use them.

bos
The bos command suite is used to contact the Basic Overseer Server (BOS Server), which is used to monitor and alter DFS processes on server machines in a cell. System administrators issue bos commands to monitor and control server processes and security; users do not use them.

cm
The cm command suite is used to customize the Cache Manager, which runs in the kernel on client machines. System administrators issue cm commands to configure the Cache Manager, modify RPC authentication levels for communications with File Servers, and to set setuid and device file status; users employ them to check machine and cell status and to determine machine and cache information.

dfstrace
The dfstrace command suite is used to trace DFS processes to obtain debugging information. System administrators use dfstrace commands to help diagnose DFS problems; users do not use them. The dfstrace commands are provided for knowledgeable administrators and developers; information about the commands is provided only in Monitoring and Tracing Tools.

fts
The fts command suite is used to manage system and user filesets. System administrators issue fts commands to create, move, replicate, remove and set advisory RPC authentication bounds for filesets; users employ them to check fileset quota information.

DFS also includes a number of miscellaneous, nonsuite commands; for example, the scout command is a miscellaneous command that is used by system administrators to monitor File Exporter usage statistics. DFS also includes an additional command suite, dfsgw, that is used with the DFS/NFS Secure Gateway to administer DCE credentials for NFS users.

System administrators can issue all DFS commands; users can issue only those DFS commands that require no administrative privileges (for example, the fts lsquota command). DFS Command Structure and Help provides information about the structure of DFS commands and describes how to receive online help for them.

Refer to Part 2 of this guide and reference for detailed discussions of the various DFS commands. Refer to the OSF DCE Command Reference for complete details about the security commands mentioned in this section. Consult the remainder of the topics in this guide for information about fileset management, system management, and most security issues referred to in this section.
