Planning to Manage File Systems
This section addresses questions you might have when planning to
administer file systems. The following topics are discussed:
• “Introduction to Managing File Systems” on page 83
• “Determining What Type of File System to Use” on page 85
• “File System Wrappers” on page 86
• “Journaled File System, the File System Default” on page 86
• “Frequently Asked Questions about the Journaled File System” on
page 87
For procedures used to administer file systems, go to “Managing File
Systems” on page 602.
Introduction to Managing File Systems
System files, application files, and user files all must reside in a file
system to be available to the operating system and applications.
The overall HP-UX file system consists of a directory tree or hierarchy,
starting from the root. Although the file system may appear as one
unitary system, it may actually consist of several different “pieces”, each
stored on different devices or on different logical volumes. To enable
users to access the files in a file system, except for the root file system,
you must “mount” the file system. This can be done either manually or
automatically at boot-up, by attaching it to a directory in the existing
directory tree. The directory where you attach the added file system is
called the mount point.
• For procedural information, go to “Mounting File Systems” on
page 605.
• For information helpful in selecting JFS mount options, go to “JFS
and the mount Command” on page 94.
You can also unmount a file system, and if you choose, re-attach it at a
different mount point.
For procedural information, go to “Unmounting File Systems” on
page 609.
