Logical Volume and New Hard Drive

Hi I am running FC5 and I have just recently bought a new 750G harddrive. I was wondering if someone could point me in the right direction on how to set this new harddrive up. What I would like to do is add it to my already existing VolGroup00. I just want to make my VolGroup larger so that I can continue to store data in the same place as I have always been doing so. This is running an FTP Server that is why I am interested in just increasing the size of the existing Group. I do not want to have to two different areas in which my data is being stored for ease of administration on my FTP Server. If anyone could offer any advice that would be great. If you need anymore information from me because I am sure that I have not supplied you with enough here just let me know and I will get that for you.

Thank You in advance for the replies

Look at the man pages for the following commands:
(e.g. man pvcreate)

vgdisplay - Shows you exsiting VG configuration.

lvdisplay - Shows you layout of an existing LV within the VG

pvcreate - to prepare the disk for LVM (Logical Volume Manager)

vgextend - to add the disk to the existing VG (Volume Group)

lvextend - to increase the size of the existing LV (Logical Volume)

You would then need to resize the filesystem that is on the LV. How to do that would depend on the filesystem type.

Try Red Hat's GUI interface for LVM. In FC5/Gnome it's under system-->administration-->logical volume management.
