Upon boot I consistently receive a Low Disk Space warning informing me that "Filesystem root" has only XXXMB disk space remaining; XXX is diminishing with each boot and is getting dangerously low.

When I scan the filesystem with Disk Usage Analyzer it shows the Total filesystem capacity at 2.0TB (used: 154.0GB, available: 1.8TB). This makes sense to me.

However, the ring chart (and table) shows the size of / at 153.5GB and warns that it's at 100% usage, with the largest files (those that are causing the so-called 100% usage) residing in /home/looie/Documents.

My partitions are setup with

  • / sized at 14.30GB (/dev/sda3)
  • /home (on /dev/sda4) at 1.8TB.

I want my documents to be stored on /home/looie/Documents on /dev/sda4 but they appear to ALSO be stored on /home/looie/Documents on /dev/sda3 causing the partition to approach it maximum capacity and generate the Low Disk Space warning.

What am I doing wrong? How can I set things up so that my data "Documents" is stored on the partition with the greatest capacity (/dev/sda4) and NOT on the smaller partition (/dev/sda3)?

can you see what the fstab file sais about /home? (gksu gedit /etc/fstab) – Jacob Vlijm Mar 28 '14 at 20:38
Just to make sure Disk analyzer is not getting confused: go to Edit -> Preferences and check that only your root device is selected. Then scan (only) the root filesystem again. – Salem Mar 28 '14 at 21:36
Here is the output of gksu gedit /etc/fstab: ! – user262698 Mar 29 '14 at 18:21

Unmount your /home partition (with Gparted or command line) and then look to make sure /home is empty (as it should be). Delete or move anything that doesn't belong. Then either mount your /home partition again or just reboot.

Thanks for the answer. I'm still confused. Why would I want "/home", which I've set up with 1.8TB of space to contain all my data in "/home/looie/Documents" to be empty? – user262698 Mar 29 '14 at 17:43
Because /home will only have looie or anything else if your 1.8TB of space is mounted. If that space is not mounted to /home, then it everything there will be stored wherever / is mounted. Basically, you want to make sure that if your 1.8TB partition isn't mounted to /home, then there shouldn't be any data there. – Nattgew Mar 30 '14 at 2:33
