Chapter 6 Managing the File System

Managing File System Operations

 

The global section of the file system configuration file contains general

Making Global Changes

parameters that control system performance, components related to the

 

 

file system’s resource consumption, and whether features are enabled or

 

disabled.

 

For most of these parameters, restarting the File System Manager (FSM)

 

causes the modified parameters to take effect. However, the File System

 

Block Size and Windows Security parameters require that the file

 

system be remade before they take effect. Remaking the file system

 

results in data loss, so you should carefully plan the initial configuration

 

of these two parameters in order to reduce the number of file system

 

remakes. If a parameter change requires a file system remake, the system

 

notifies the administrator in the system log.

 

The global section also contains several parameters that can dramatically

 

improve or degrade system performance, so you should exercise caution

 

when modifying performance parameters.

 

Before making any changes to the file system’s configuration, carefully

 

review the cvfs_config(4) man pages or the “CVFS Configuration File”

 

help file.

 

The following task describes how to modify global configuration settings.

 

These settings affect all stripe groups in the file system.
