Here's the situation. I have a dual boot machine - originally had Red Hat and Windows 2000 Pro. The NTFS partition never did seem to 'get along' with the Adaptec 2400A caching RAID controller. Linux always seemed to like the I2O drivers. I went from RH Enterprise to now running Centos 5.5. Works great! I really don't want the 200 gigs worth of NTFS. Can't I just run GParted from a CD, reformat the NTFS and append the space to the existing Linux partition? What will I have to do with LVM to see the expanded partion? - anything special? I've never done this before - is it really much more complicated than I've outlined here? Please advise this old simpleton. Many thanks in advance.

The *easy* solution would be to just reformat the NTFS partition as a LVM physical volume -- use a paritioning tool to change its Id to 8e (if the RAID volume is small enough for a normal DOS partition table, fdisk will do this just fine), then do a 'pvcreate /dev/sda<mumble>'. Then just add this partition to your existing LVM volume group using 'vgextend <Your VolumeGroupName> /dev/sda<mumble>'. Now you can use lvcreate, lvresize, etc. as usual. Don't forget to fix things in /boot/grub/ (you don't want to attempt to boot the now wiped MS-Windows system). You can do this all from your CentOS system and don't even have to reboot the system.
This assumes that you have already backed up what you want/need from the '200 gigs worth of NTFS' -- I presume you don't need the Windows 2000 Pro system files, but if there is stuff you want in places like My Documents, you should of course copy them off somewhere.
