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 an external storage which i tried to expand(with succes) and then de-expand(no succees). The Storage manager didn't support this type of function so i had to create again the physical and logical drives.
I had to clear the partition since linux was indicating different partition size and physical size with corrupt partition table error message
so I used
and the prompt
: o (create a new empty dos partition table) and
mkfs -t ext3 /dev/sdb
mount -t ext3 /dev/sdb /stdb
the drive mounts OK but when i issue
it gives me the following
Disk /dev/sdb: 291.4 GB, 291481059328 bytes
255 heads, 63 sectors/track, 35437 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk /dev/sdb doesn't contain a valid partition table
What does this mean (doesn't contain a valid partition table)
It seems that the drive works OK (copying files) but is it?
You made a small mistake:
you created an empty partition table, but didn't add any partitions.
I find it a bit strange it works, but apparently it does? I have no idea if it can be reliable, if I were you I'd redo it:
in fdisk, add a partition with
# fdisk /dev/sdb
a (for add)
1 (partition number)
then let it cover the entire disk, simply accept default start & end.
w (write and exit)
Maybe all your files are still on it? Could be worth checking, it might be you don't have to reformat - again, I have no idea if the partition can be relied upon without reformatting.
I have created RAID 5 using hda5,hda6 and hda7 while installing RHEL 5.
But still it works. But for the #fdisk -l command I got the message "Disk /dev/md0 doesn't contain a valid partition table"
whatis the wrong?
Exactly nothing. fdisk is trying to look for partition table on /dev/md0 device. It cannot find it there so it gives this information. fdisk cannot in any way guess that /dev/md0 is not a 'real' disk (strange but true).
