adding swap partition

[Chiu, PCM (Peter)]

Dear Rick,

>which will cause the file to be used automatically at your next boot. Also
note that the maximum size of a single >>swap partition or file is 2GB, but
you can have up to 8 of those (16GB total swap).

How do you determine the limits on the maximum swap file or partitions and
their total number?
 
Peter

You can create an empty file of the size you want, use "mkswap" on the file
to convert it to swap format, then enable it using the swapon command.

For example, to create a 512MB swap file, find a filesystem that has 512MB
free (use the "df -h" command).  Let's assume that's on your /var
filesystem.  As root:

	# dd if=/dev/null of=/var/swapfile bs=1M bc=512
	# mkswap /var/swapfile
	# swapon /var/swapfile

You can then edit your /etc/fstab file and add a line like:

	/var/swapfile    swap          swap    defaults        0 0

which will cause the file to be used automatically at your next boot. Also
note that the maximum size of a single swap partition or file is 2GB, but
you can have up to 8 of those (16GB total swap).

If you have unassigned space on your hard drive, you can create a swap
_partition_ and use it.  I don't know what kind of error you got, but the
most common one in disk druid is trying to specify a mountpoint for a
partition with the "swap" filesystem type.  I'd sure like to know what you
did and what error you got.
