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.

hey all! i'm having trouble creating new paritition with my redhat 9
here is the printout of the fdisk
# fdisk -l /dev/hda
Disk /dev/hda: 4327 MB, 4327464960 bytes
255 heads, 63 sectors/track, 526 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/hda1 * 1 13 104391 83 Linux
/dev/hda2 14 461 3598560 83 Linux
/dev/hda3 462 526 522112+ 82 Linux swap
I want to create another partition. when i do fdisk on /dev/hda, it says i dont have any free sectors, which is fair enough. then i tried to do fdisk /dev/hda2 to see if i can make up a new partition from there. im not sure whether u r allowed to do that, as to me it looks like im tryin to resize?
anyhow, since this paritition is online, linux asked to be reboot to make the new partition active. before reboot, i printed the partition table and it showed the below
Device Boot Start End Blocks Id System
/dev/hda2p1 1 13 104391 83 Linux
after reboot, i thaught i need to created a file system on the partition. when i executed mke2fs /dev/hda2p1, it said device doesnt exist!
what am i doing wrong here? pls excuse my ignorance, im new to all this stuff. TIA

Ok, the entire physical drive in your machine is labeled as hda, hdb, hdc, or whatever. When you see hda1, hda2, or hda3 for example, those refer to partitions within the same hard drive.
When you tried to create a partition on /dev/hda and it said you had no more sectors, that meant all of the space on that hard drive was used. Changing to /dev/hda2 won't change that, because it's still part of the same hard drive. In fact, I'm not sure why fdisk even allowed you to do that. You would be trying to create a partition within a partition, and to my knowledge, that's not possible.
You will need to either:
1. Install a new hard drive and create one or more partitions on it
2. Resize your current partitions to make room for another one. Be aware that resizing typically means you will lose all data on partitions you change. There are tools that say they can resize a partition without data loss, but I've heard mixed reviews about all of them.
I don't use them actually. I have heard "Partition Magic" mentioned a number of times, but it's a commercial tool.
Whenever I need to change my partition scheme, I simply make a backup copy. I use tar to store the partition's contents into a single file, burn it to a cd, change the partition, use a "rescue" CD (like Knoppix), and then extract the tarball(s) to the new partitions. I'd only try this is you're comfortable with your rescue system, and you're confident you won't forget anything important. Essentially it's the backup-reformat-restore routine.
