Various hard drive -partitions, CD-ROMs, and floppies are all placed in the same tree. In order to attach -these drives to the filesystem so that you can access them, you have to use the <tt -class="COMMAND">mount</tt>(1) and <tt class="COMMAND">umount</tt>(1) commands.</p> - -<p>Some devices are automatically mounted when you boot up your computer. These are -listed in the <tt class="FILENAME">/etc/fstab</tt> file. Anything that you want to be -mounted automatically gets an entry in that file.

In this case, the devices are five partitions -spread out across two SCSI hard drives, two special filesystems that don't need a device, -a floppy, and a CD-ROM drive. The second column is where the device will be mounted. This -needs to be a directory name, except in the case of a swap partition. The third column is -the filesystem type of the device. For normal Linux filesystems, this will be <var -class="LITERAL">ext2</var> (second extended filesystem). CD-ROM drives are <var -class="LITERAL">iso9660</var>, and Windows-based devices will either be <var -class="LITERAL">msdos</var> or <var class="LITERAL">vfat</var>.</p> - -<p>The fourth column is a listing of options that apply to the mounted filesystem. -defaults is fine for just about everything. However, read-only devices should be given -the <var class="LITERAL">ro</var> flag. There are a lot of options that can be used. -Check the <tt class="FILENAME">fstab</tt>(5) man page for more information. The last two -columns are used by <tt class="COMMAND">fsck</tt> and other commands that need to -manipulate the devices.

All you have to do is use the <tt -class="COMMAND">mount</tt> command, along with a few options. Using <tt -class="COMMAND">mount</tt> can simplified if the device has an entry in the <tt -class="FILENAME">/etc/fstab</tt> file. For example, let's say that I wanted to mount my -CD-ROM drive and that my <tt class="COMMAND">fstab</tt> file looked like the example from -the previous section. I would call <tt class="COMMAND">mount</tt> like so:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">%</samp> <kbd class="USERINPUT">mount /cdrom</kbd> -</pre> -</td> -</tr> -</table> - -<p>Since there is an entry in <tt class="FILENAME">fstab</tt> for that mount point, <tt -class="COMMAND">mount</tt> knows what options to use.

The <var -class="OPTION">-t iso9660</var> is the filesystem type of the device to mount. In this -case, it would be the iso9660 filesystem which is what CD-ROM drives most commonly use. -The <var class="OPTION">-o ro</var> tells mount to mount the device read-only. The <tt -class="FILENAME">/dev/cdrom</tt> is the name of the device to mount, and <tt -class="FILENAME">/cdrom</tt> is the location on the filesystem to mount the drive.</p> - -<p>Before you can remove a floppy, CD-ROM, or other removable device that is currently -mounted, you'll have to unmount it. That is done using the <tt -class="COMMAND">umount</tt> command. Don't ask where the “n” went because we -couldn't tell you. You can use either the mounted device or the mount point as the -argument to <tt class="COMMAND">umount</tt>. For example, if you wanted to unmount the -CD-ROM from the previous example, either of these commands would work:</p> - -<table border="0" bgcolor="#E0E0E0" width="100%"> -<tr> -<td> -<pre class="SCREEN"> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">umount /dev/cdrom</kbd> -<samp class="PROMPT">#</samp> <kbd class="USERINPUT">umount /cdrom</kbd> -</pre> -</td> -</tr> -</table> -</div> -</div> - -<div class="NAVFOOTER"> -<hr align="LEFT" width="100%" /> -<table summary="Footer navigation table" width="100%" border="0" cellpadding="0" -cellspacing="0"> -<tr> -<td width="33%" align="left" valign="top"><a href="filesystem-structure-links.html" -accesskey="P">Prev</a></td> -<td width="34%" align="center" valign="top"><a href="index.html" -accesskey="H">Home</a></td> -<td width="33%" align="right" valign="top"><a href="filesystem-structure-nfs.html" -accesskey="N">Next</a></td> -</tr> - -<tr> -<td width="33%" align="left" valign="top">Links</td> -<td width="34%" align="center" valign="top"><a href="filesystem-structure.html" -accesskey="U">Up</a></td> -<td width="33%" align="right" valign="top">NFS Mounts</td> -</tr> -</table> -</div> -</body> -</html> - |
