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.

Hello, I have two 3TB drives in Raid 1. During installation problems with GPT, I had to create two partitions on a 300GB and the other of the remaining space. On the partition of 300GB I installed RedHat 5.
I have about 2500GB remaining I can not mount them. The situation is that you can see in the screenshot attached to this post.
Space that can not be mounted I want to install DB2 for use as a storage Db.
I created a partition on sdb sdb1 named, as you can see below:
[root@localhost /]# fdisk /dev/sdb
WARNING: GPT (GUID Partition Table) detected on '/dev/sdb'! The util fdisk doesn't support GPT. Use GNU Parted.
The number of cylinders for this disk is set to 325634.
There is nothing wrong with that, but this is larger than 1024,
and could in certain setups cause problems with:
1) software that runs at boot time (e.g., old versions of LILO)
2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
WARNING: The size of this disk is 2.7 TB (2678435832320 bytes).
DOS partition table format can not be used on drives for volumes
larger than 2.2 TB (2199023255040 bytes). Use parted(1) and GUID
partition table format (GPT).
Command (m for help): p
Disk /dev/sdb: 2678.4 GB, 2678435832320 bytes
255 heads, 63 sectors/track, 325634 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Device Boot Start End Blocks Id System
/dev/sdb1 1 267350 2147483647+ ee EFI GPT
but I can not mount it in any way.
[root@localhost mnt]# mount -t ext3 /dev/sdb1 /dev/
mount: /dev/sdb1 already mounted or /dev/ busy
If you are using the GParted CD, are you able to see sdb by clicking the down arrow in the upper right of the window which shows the different drives? When you select /dev/sdb, do the partitions show in the main window? If you do, do you click on /dev/sdb1 to highlight it then click on the Partition tab at the top, select unmount then go back and select Format to? If you are doing these things it should work.
Check your /etc/fstab and /etc/mtab files to see if there is an entry for sdb1 there and comment the line out before you try to format.
It might be due to RAID which I'm not familiar with. You might post details on each step you have taken.
open a console and type 'mount' without the quotes, post the output please.
I was able to mount the partition, but I had to reinstall RedHat.
Below is the output of the command 'mount':
[root@localhost ~]# mount
/dev/sda2 on / type ext3 (rw)
proc on /proc type proc (rw)
sysfs on /sys type sysfs (rw)
devpts on /dev/pts type devpts (rw,gid=5,mode=620)
/dev/sdb1 on /home type ext3 (rw)
tmpfs on /dev/shm type tmpfs (rw)
none on /proc/sys/fs/binfmt_misc type binfmt_misc (rw)
sunrpc on /var/lib/nfs/rpc_pipefs type rpc_pipefs (rw)
/dev/sdc1 on /media/VID type vfat (ro,nosuid,nodev,shortname=winnt,uid=0)
But I'm not happy with what I did. With the availability of 3TB, I wish to 1TB for the OS , And 2TB for DB2 and the DB.
I would like to create a 2TB partition, only data that is to be devoted only to the DB.
