Swap partition

Hi everyone,

I have a question about swap partitioning. When I installed RH 9.0 I was, for some reason, unable to create a swap partition. Now that I've got it installed though, I really would like to have one.

I have an existing 1500MB swap partition, that I use for Windows; am I able to use this for a Linux swap also? I had to change some virtual memory settings under XP to get it to write to the correct drive, and I guess I'm wondering if RedHat has the same sort of thing.

If that's not possible, then does anyone have any info on if I can still create one after installation? That's all folks.

You can use it for Linux, sure, but I'm not sure if it would confuse Windows. Because I think you'd have to 'mkswap' and then 'swapon' and then add it to your fstab. But then, whether Windows would use it as normal, I don't know.

1 and a half gigs? Yikes. That's a lotta swap.

- Oh, and to the second question, if you've got free space, use it. If not, you'd have to look into parted and resizing yourself some swap space.

What format is the partition? If it's linux swap filesystem, then sure, you can use it

You'll need to use something like fdisk or mkswap to change the type of partition it is though if it's not a linux swap (use:
/sbin/fdisk -l to find out, as root of course ).

After you make it a linux swap you'll wanna add it to your fstab, something like:
/dev/hdx swap swap defaults (or sw depending on the documentation you find) 0 0

You'll then need to "swapon" which means just type that into a terminal, again, as root. This turns the swap on. Then enjoy.
