Making Global Changes 6
The global section of the file system configuration file contains general
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.
1 From the SNFS home page, choose Globals from the Config menu.
The Modify Global Settings
screen appears.
