I am new to ubuntu, and I installed it following one tutorial. In the tutorial it says it is enough to give "/" 30 GiB. However, now my "/" is 60% occupied. Is this normal? Should I give more space to it?

I reinstalled ubuntu once, I am guessing if this caused that high occupation.

You can find out which directories/files that are occupying most of the drive space in your root partition.

  It helps if you tell us how you did the re-installation.

  
  
  
  
  
  • Is there a (big) swapfile?
  
  
  • Are there files/directories left from previous installations?
  
  
  • Have you installed some huge program packages?

  You can try the following commands to identify the directories/files that are occupying most of the drive space,

  
  
  

  sudo find / -maxdepth 3 -exec du -hs {} ; |sort -h
  
  

  
  
  

  or the long command line (that you can copy and paste, and modify lines=30 if you want to see another number of lines with big directories/files)

  
  
  

  lines=30;for i in $(LANG=C df|grep '^/dev/'|tr -s ' ' ' '|cut -d ' ' -f 6-);do echo "--- This is the viewer 'less', quit with 'q' ---";sudo du "$i" -hx|sort -rh|head -n$lines;done|less
  
  

  
  
  

  and the graphical program (you may have to install it)

  
  
  

  baobab
  
  

  
  
  

  or to see what a regular user cannot see

  
  
  

  sudo -H baobab
  
  

  
  

You have installed with a 30 GB root partition (/, sdb6) for the system files, and a separate 261 GB partition for home (sdb5). In such setup, all your user data will go into the separate home partition, which provides plenty space.

Ubuntu typically needs no more than 10-12 GB for system files (/). 30 GB is plenty for a system partition if you have a separate home partition.

You are now at 18 GB, which is relatively much. This could be due to many old kernels still remaining on the system, or on large log files. Or perhaps other than Ubuntu system files have been put at some time on that partition 30 GB for a separate home partition is plenty. You may want to examine the contents of that partition sdb6 using a tool such as Disk Usage Analyzer to see what might be causing this larger disk space use.

It might be wise to do that from a live session, started from an installation CD or USB. Perhaps, some old user data is present in the /home folder on the system partition sdb6. Since currently, your separate /home (sdb5) partition is mounted on that folder, the contents that might be in there are currently obscured. When you work from a live session, nothing will be mounted on the folders of your system partition (sdb6).

Look "/" is called root partition in linux and all files are stored under it. You can choose size by expecting what you want to do in ubuntu
