Hello

I have recently added a hard disk to an existing raid array container. I wish to create a new partion, assign the new hard disk space to the partition, and then ultimately add the partition to an existing lvm. please see below:

[root@pasty ~]# fdisk /dev/sda

The number of cylinders for this disk is set to 35632.
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)

Command (m for help): p

Disk /dev/sda: 293.0 GB, 293089574912 bytes
255 heads, 63 sectors/track, 35632 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

My problem is, when i attempt to create the new partition (sda10) i m not prompted to specify the end cylinder(ie the size of the partion). instead i end up with a partition of no specified size:

/dev/sda1 * 1 13 104391 83 Linux

/dev/sda10 26724 26724 8001 83 Linux



any idea how i can increase the size of partition sda10 to utilise the space on the new hardisk??
any help will be much appreciated

The extended partition (sda4) ends at cylinder 26274, so that's as far as fdisk will go in creating a new logical. If you change fdisk to display sectors instead of cylinders, you will probably see that it did create something with a few sectors.

What you need to do is re-size the extended partition using GParted or QTParted.

thanks for that pixellany...that helps.
by the way, i dont have graphical mode, will it be ok to use gparted live cd to boot off from and then to increase the extended sda4 partition?( i ask coz this method is only used if youre not "up and running")

That's the way to go--definitely. You can't be using the partitions that you are re-sizing.
