Managing Systems and Workgroups: A Guide for HP-UX System Administrators

Planning a Workgroup
Planning to Manage File Systems
Chapter 284
There are a variety of reasons why you might create a new piece of the
overall file system, including:
• You have just added a new non-LVM disk or logical volume.
• You are concerned about the possibility of running out of disk space
for your users’ files (or you actually have run out of disk space).
• You wish to separate portions of a file system physically, either to
restrict growth of files within a portion of the file system or to
increase access speed for better performance. For example, you may
wish to keep the root file system as small as possible for performance
and security reasons. Or, you may wish to provide for a distinct group
of users and their needs, or to separate certain data with distinct
characteristics.
• You wish to replace a larger file system within a non-LVM disk or
logical volume with a new smaller one. This may require that you
create a new file system within that non-LVM disk or logical volume.
For procedural information, go to “Creating a File System” on
page 603.
