How do I increase swap space in an exiting partition configuration? Do I have to start over, i.e., redo partions & reinstall my Red Hat 7.3?

No, you use parted. It has 'resize' option.

Delete all partitions and then re-install and re-configure.

That would be a start.

JStew, why do you think it's the best idea? Reinstallation requires data backup, while parted and 'resize' option make everything much easier.

Just an opinion...

Why not just use a swap file?

To add swap you can create a swap file,

For eg:
Assuming you want to create this swap in /swap and having size 512M.

Run the following commands

dd if=/dev/zero of=/swap bs=512k count=1024
mkswap /swap
chmod 0600 /swap
swapon /swap

you will also have to add this line to /etc/fstab
/swap swap swap defaults 0 0

You can run free -m to find the swap space used in megabytes before and after the allocation of swap space.

how much actual ram do you have?

if you have 512mb or more then you really dont need a /swap partition IMHO

Thanks for all the suggestions... I'm adding .5GB to my existing .5GB of RAM & I want to increase my swap space from .5GB up to at least 1.5GB. Right now my disk space is set up as follows:

Device Boot Start End Blocks Id System
/dev/sda1 1914 4427 20193705 83 Linux
/dev/sda2 1 9 72261 83 Linux
/dev/sda3 10 1913 15293880 5 Extended
/dev/sda5 10 264 2048256 83 Linux
/dev/sda6 265 456 1542208+ b Win95 FAT32
/dev/sda7 457 584 1028128+ 83 Linux
/dev/sda8 585 650 530113+ 82 Linux swap
/dev/sda9 651 714 514048+ 83 Linux
/dev/sda10 715 727 104391 83 Linux
/dev/sda11 728 1913 9526513+ 83 Linux

I didn't set it up this way myself & now I want to change it. My guess is that I can convert the Win95 FAT32 (/dev/sda6) partition which I don't use to Linux Swap space & I'm done. Right???

If you're going to have a total of 1Gig of ram, you really shouldn't need 1.5 Gigs of swapspace.

Use the diskspace for something else more worthwhile

1GB RAM+1.5GB swap would be good for film editing, but not for normal use...
