Swapped off in order to be able to use vgreduce. So partitions are ok but i cannot boot, i thought this was a bad fstab, so i mounted root partition with the live usb key to acces fstab to fix the issue. Fstab seems ok (i replaced /dev/mapper/home-home by /dev/mapper/root-home same for swap). But when i try to boot the system still tries to load the Home vg though it doesn't exist anymore, i don't get it, what am i missing here? Obviously there is a place in the filesystem where i have to change things also but i don't know where.
