I'm having problems with my disk usage. My system monitor says that I have 44,6gb used. But when I run disk usage analyzer, it shows that I have 5.4gb used. My partitions are in LVM. Here some images:

Here the df -a result too:

  • Sorry for not be clear. My question is why my system monitor says that im using 44GB and my disk usage 5.5GB. Im not sure that i`m using all this space in root partition. Is like the root partition kept the disk usage that he had before the partition. – Marcus Lima Nov 11 '14 at 11:24
  • @MarcusLima You have a triangle next to the /usr/ directory, you can click on it, and see the subdirectories and their 'weight'. This may provide some information as to what is using this data. It can be many things, you could have installed something like bitcoin application or gnunet or many other things. – v010dya Nov 11 '14 at 12:18

When i had resized my ROOT volume and copied my Home files to my HOME volume, the 'rm' not erased my encrypted files. I just boot my system with a live CD, mounted my /root volume and use 'rm -f' to erase all files inside the home folder in /root.Thus, the hidden folder .encrptfs was deleted.
