If you are planning to use a swap partition for virtual RAM, you're
|
|
ready to prepare it for use.<A NAME=tex2html270 HREF="footnode.html#1337"><IMG ALIGN=BOTTOM ALT="gif" SRC="foot_motif.gif"></A> In Chapter <A HREF="node155.html#chapsysadmnum">4</A>
|
|
we will discuss the preparation of a swap file in case you don't want
|
|
to use an individual partition.
|
|
<P>
|
|
Many distributions require you to create and activate swap space before
|
|
installing the software. If you have a small amount of physical RAM,
|
|
the installation procedure may not be successful unless you
|
|
have some amount of swap space enabled.
|
|
<P>
|
|
The Slackware distribution requires you to create swap space,
|
|
before installation, if you have 4 megabytes of RAM or less.
|
|
If this is not the case, the Slackware installation procedure
|
|
can be used to prepare swap space automatically. If in doubt,
|
|
go ahead and follow the procedure described here; it can't hurt.
|
|
<P>
|
|
The command used to prepare a swap partition is <tt>mkswap</tt>, and it takes
|
|
the form
|
|
<P><TT> mkswap -c <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img57.gif"> <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img58.gif"> <P></TT>
|
|
where <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img59.gif"> is the name of the swap partition,
|
|
and <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img60.gif"> is the size of the partition, in
|
|
blocks.<A NAME=tex2html271 HREF="footnode.html#1368"><IMG ALIGN=BOTTOM ALT="gif" SRC="foot_motif.gif"></A>
|
|
For example, if your swap partition is <tt>/dev/hda3</tt> and is
|
|
10336 blocks in size, use the command
|
|
<P><TT> # <em>mkswap --c /dev/hda3 10336</em>
|
|
<P></TT>
|
|
The <tt>-c</tt> option tells <tt>mkswap</tt> to check for bad blocks on the
|
|
partition when creating the swap space.
|
|
<P>
|
|
If you are using multiple swap partitions, you will need to execute the
|
|
appropriate <tt>mkswap</tt> command for each partition.
|
|
<P>
|
|
After formatting the swap space, you need to enable it for use by the
|
|
system. Usually, the system automatically enables swap space at boot time.
|
|
However, because you have not yet installed the Linux software, you need
|
|
to enable it by hand.
|
|
<P>
|
|
The command to enable swap space is <tt>swapon</tt>, and it takes the form
|
|
<P><TT> swapon <IMG BORDER=0 ALIGN=BOTTOM ALT="" SRC="img61.gif"> <P></TT>
|
|
In the example above, to enable the swap space on <tt>/dev/hda3</tt>, we use
|
|
the command
|
|
<P><TT> # <em>swapon /dev/hda3</em>
|
|
<P></TT>
