I'm completly confused. Per accident more or less I gave my PC 100 GB for root. And now Ubuntu tells me I am out of space, 0 byte left. I cleared the trash to get a little bit to work with (5GB), still tells me zero bytes left, allthoug I managed to mount my backup drive. And I read people are using 30 GB and less for root. I am using SystemBack to avoid long installation time and to get the system I am used to. I partitioned as followed:

  • GPT Partion table
  • / 100GB
  • Boot/Efi 200MB
  • SWAP 6GB
  • Home rest ~2TB

I installed around 2 weeks ago, and root is full. If I knew how to search for big files or folders, would be a great help. edit is what I am looking for

    The command sudo du -aBM -d 1 . | sort -nr | head -20 will show you the largest twenty files / subdirectories of your current directory. The first time you run it, it takes a while as it reads the directory structure. – Charles Green Aug 12 '17 at 13:51

    To me it looks as if it definitely shouldn't use 100GB. Could you please post the output of df -h | grep "/$"? (It should show how much space is left on the root partition - just in case the notice you get is somehow bugged...)

    (Edit: Or you could try df -h | egrep "(/$|File)" which results in the same but with the header)

    maybe inode issue... – Tamil Selvan C Aug 12 '17 at 14:40

    It would help to see the mount points, and a modification to the directory sort I posted earlier would help. Please run df -h, df -ih and sudo du -axBM -d 1 / | sort -nr | head -20 and append the outputs of these commands into your question, rather then into a comment. – Charles Green Aug 12 '17 at 15:52
  • dag@CD01:~$ df -h | egrep "(/$|File)" /dev/sda1 116G 116G 0 100% / – DJNJ Aug 12 '17 at 17:18
  • can I place the results elsewhere? too long for the outpust here – DJNJ Aug 12 '17 at 17:21
  • And I have german, must switch to english – DJNJ Aug 12 '17 at 17:22
  • If the output is too long to be added to your question (is there a limit?) you could maybe put it on pastebin.

    I'm pretty sure that there's no need to change the language, most of the text is in the headers in the first line of the output anyways.

    Possible duplicate of How do I free up more space in /boot? – Pilot6 Aug 12 '17 at 17:44

    Looks like /media is the culprit. – Organic Marble Aug 12 '17 at 18:11
  • How many kernels do you have? – Andrea Lazzarotto Aug 12 '17 at 18:11

    Ubuntu kernels? 1 Agree with /media, looks strange – DJNJ Aug 12 '17 at 18:17
  • looked at one porposal, How do I free up more space in /boot? – DJNJ Aug 12 '17 at 18:20
  • sems I have a lot of linux. funny they doesn't show up at booting time, in that case I would have been aware. I try that – DJNJ Aug 12 '17 at 18:21
  • please look at the original question, as I have added some outputs there. btw. if I delete old linux-kernels in /boot of course will not help at all, I tried one – DJNJ Aug 12 '17 at 19:16
  • I supose it will not help me much to reinstall again with SystemBack. I suppose the error lies in the preinstalled system already. When I install completle new now, can you advice me how much space I can give to every partitio? Also in future I want to use SystemBack, because I can easely install all my PC's (2) and Laptops(4) with one setup. And for that I need 4 partitions – DJNJ Aug 12 '17 at 19:39
  • I thank you all for your support. I installed neew with 30GB root. On the original PC ro0t has stayed stable with 9GB since months – DJNJ Aug 13 '17 at 05:20
