Table 28-2 lists the commands in the /usr/sbin directory that you use to mount and unmount file systems.

Table 28-2 Commands for Mounting and Unmounting File Systems


Command	Description
mount(1M)	Mounts file systems and remote resources.
mountall(1M)	Mounts all file systems specified in the `/etc/vfstab` file. The `mountall` command is run automatically when entering multiuser run states.
umount(1M)	Unmounts file systems and remote resources.
umountall(1M)	Unmounts all file systems specified in the `/etc/vfstab` file.

The mount commands will not mount a read/write file system that has inconsistencies. If you receive an error message from the mount or mountall command, you may need to check the file system. See Chapter 31, Checking File System Integrity for information on how to check the file system.

The umount commands will not unmount a file system that is busy. A file system is considered busy if a user is in a directory in the file system, or if a program has a file open in that file system.
