My main Ubuntu partition is an LVM 120GB of size, which keeps a 20GB /, and a 100GB /home. The rest of the harddrive was used by Windows NTFS partitions. However, I got rid of the Windows partitions, and would like to extend the LVM to all the disk. I've tried with GParted Live CD but it says it can't, and Parted Magic uses GParted. What should I use for resizing the LVM?
