I'm really stuck with trying to increase the size of the partition sda5 which is a lvm2. I'm quite new to linux and am really pulling my hair out here.
From what I've read, LVM's are supposed to be really flexible but I'm not finding it to be so.
In this GParted screenshot, you can see sda2 and sda5 are locked. Now I've read quite a few articles saying boot off a dvd, which is what I've done here. I've tried the umount command but it says it is not mounted.
If someone has any advice on where to proceed, it would be greatly appreciated.
