Plex “Not Enough Disk Space To Convert This Item”

If you have ever installed Plex on a default installation of Ubuntu, you might have noticed that Ubuntu doesn’t take up the entire disk space for the root (‘/’) partition. This is the reason Plex has the issue described in the title.

This is VERY annoying.

I was really struggling with this issue for a good couple of weeks. When I searched for this issue, none of the results were helpful.

What I had to do: Used a live CD of gparted to increase the space of the partition and then use lvm for the partition to extend into all the new free space.

So, steps below:

  1. Shutdown and boot into GParted live CD/ISO

2. Startup the GUI and extend the partition you want to expand

3. Close the GUI and open the GParted Terminal

4. Enter the LVM manager using: sudo lvm

5. Extend the default ubuntu vg/ubuntu-lv partition to use all available space: lvextend -l +100%FREE /dev/ubuntu-vg/ubuntu-lv

6. Now you can exit the LVM manager: exit

7. Finally, you can resize the system to use the newly sized partition: sudo resize2fs /dev/ubuntu-vg/ubuntu-lv

You can now use df -h and check that the system is using the entire space of the drive and the available partition.

You will now find that the root (‘/’) directory is no longer 99%/100% full and your media can play.
