Mounting or Unmounting a File System

This procedure describes how to mount and unmount remote and local file systems.

Mounting makes file systems, files, directories, devices, and special files available for use at a particular location in the file tree. It is the only way a file system is made accessible to users.

Prerequisites

Check the file systems before mounting by using the procedure Verifying File Systems or running the fsck command.

Note: If an unmount fails, it might be because a user or process has an opened file in the file system being unmounted. The fuser command lets you know which user or process might be causing the failure.
