Additionally, output from my df -h command and fdisk -l command. Where and how could I utilize space from my /dev/sda4 and /dev/sda5 partitions? I suspect /dev/mapper/fedora-root to be my LVM partition but how come the GNOME disk utility and terminal commands differ in size measurements? How can I add more space to my system, I am at 98% I shrunk the size of my dual booted windows OS and received 18 GB in free space, although I shouldn't even need to use this as I am trying to identify where and how I can utilize space form /dev/sda4 and /dev/sda5

Am I confusing logical and extended partitions from LVM partitions?

    Where exactly you want to increase your space, show us the output of lvdisplay and vgdisplay – Mongrel Jan 28 '16 at 6:56
  • @AngRed I want to expand the space on my /dev/mapper/fedora-root root parition as I have only 2% disk space left. I updated my question with the output of those commands. – phillipsk Jan 30 '16 at 5:49

In this particular scenario, you have 3 primary and 1 extended partition. If you look at the output of fdisk -l and pay attention to /dev/sda2 End and /dev/sda3 Start, you have a bit of space there.

My guess is that your only option is to move data from /dev/sda3 (/boot) partition over network or with some external media (USB etc), unmount /boot, delete /dev/sda3 and create new (or see if you can resize it without deleting) using all space available, run pvcreate /dev/sda3, run vgextend fedora /dev/sda3, and then use can finally run lvextend -r -l 100%FREE /dev/mapper/fedora-root

Finally you can bring files back into /boot directory, only this time it will not have it's separate file system. You can create an lvm and mount it on /boot if you don't use all of the free space extending / file-system.

Any issues, please let me know.

  • /boot needs to be a separate filesystem, even a primary partition for grub and boot to work. – vonbrand Feb 1 '16 at 16:52
