Introduction to Linux - A Hands on Guide
This guide was created as an overview of the Linux Operating System, geared toward new users as an exploration tour and getting started guide, with exercises at the end of each chapter.
For more advanced trainees it can be a desktop reference, and a collection of the base knowledge needed to proceed with system and network administration. This book contains many real life examples derived from the author's experience as a Linux system and network administrator, trainer and consultant. They hope these examples will help you to get a better understanding of the Linux system and that you feel encouraged to try out things on your own.

I have two hard drives in my computer - one is 4 GB, the other is 2 GB. When I installed Red Hat, I had 48 MB of RAM in my computer. Red Hat gave me a swap partition of 180 MB on the 4 GB hard drive.
I added another 128 of RAM yesterday, and have read that i should have swap space of twice the amount of RAM. My 4 GB hard drive has no space left for partitions. But my 2 GB hard drive is almost all free.
So my question is this - should i delete the old swap partition from the 4 GB drive and create one new swap partition on the 2 GB drive that is twice the size of my total amount of RAM? In this case, what do I do with the space left from the old swap partition? Is there an easy way to add it to one of my other partitions, or will it just be wasted?
Or, should I create a separate swap partition on the 2 GB hard drive (and not delete the old swap partition) so that both partitions together add up to twice the size of the RAM?
Is it bad (or impossible) to have swap partitions spread out over two hard drives?
no, your swap is fine as it is, indeed it'll be used less now than before. that stupid rule about being 2xram is just a daft archiac old rule from when you had a remortage your house for a stick of ram. many people still keep blindly reciting it tho. it does have a certain application as far as high end servers go, but gerneally it's irrelevant.
