creating swap

Hi All

I have a problem with partitioning on RedHat 9. When I try to create swap partition on my desktop, I couldn't.
There are two OS one of them is Win XP and second one is RedHat 9.
At the end of installation there were /boot and / partitions without swap.
Is there anybody to help me? How can I create swap partition on my desktop?

Thx

just create a extra partition (you do have extra space on your hard drive that is unpartitioned right?)

man mkswap is your friend together w/ cfdisk (but be careful!)/partitionMagic.

Yes I have enough unpartitioned space.But I tried to create swap space using redhat's documents (http://www.redhat.com/docs/manuals/l...ap-adding.html).

i read the first few lines of those instructions and I'm already lost!,

OK heres how, first: what device is the partition on? for the example ill assume /dev/hda4

Code:

fdisk /dev/hda

in that type

Code:

that will display all the partitions, normally you can only have 4, but if you choose you can sacrifice 1 in order to get multiple "logical" partitions (extended partitions, so how many doe you have already?
now type in

Code:

(unless your your gonna make the last one an extended partition thingy)
then press "enter" and now it should be asking you how much space do you want it to be?, enter in something like +100MB, or how much you want, leave it blank and it will make it as big as it can be (all the unpartitioned space)
now press

Code:

then enter the new partition number,
and change the value to 81 (i think its 81?)
then press

Code:

again, and see if you new partition is listed, it should also say by it "linux swap", if not then press "t" and try 82, or 83 (i think it was one of those) ..... now press

Code:

now that your new partition is ready, type:

Code:

mkeswap /dev/hda4

now just add a new line to your /etc/fstab file and your set, the line should look like

Code:

/dev/hda4 swap swap 0 0

(or just copy the other swap line that should be there, changing the device name of course,)

now just reboot and it should be set

I tried the last procedure. But it didn't work.
However I found the real problem.When I partitioned the disk there was 8 GB disk space unallocated for Linux. As you know I created / and /boot partitions but not swap.The unallocated disk space doesn't allow to create swap partition.
After fdisk and repartition I could create swap partition correctly.
