Ask Ubuntu is a question and answer site for Ubuntu users and developers. It's 100% free, no registration required.

I had recently run a script in our college exam on my computer which was specifically for 32bit(i386) but my ubuntu is amd64 , so the script wouldn't run but then I tried accessing the folders in my home folder which gave me permission denied. So I did a sudo chmod 777 -R /home/username , which gave me permissions to complete the test even though I was put as an exception to take my test without using the script to run successfully. After all this and another two days later I started facing problems of less space on my drive but I probably should have had plenty of space. Then it said that I have 1.4 kb space left on the system. I searched for my problem on the net and somewhere I found an answer on askubuntu which I am not able to find again. It said that, what actually happened is that the home directory should have 644 permission rather than 777 and so the files I deleted had their INODES still present along with the new files I added to the directory and hence there is no space left. I have removed everything from the home directory and when I try to add a file with size less than a kb it still says no space left. Any help or suggestions will be appreciated.

post the output of df -h? –  Avinash Raj Mar 8 at 4:58
It would be better if you upload gparted screenshot.Take a screenshot and then upload it to imgur.com.Finally post the uploaded link here. –  Avinash Raj Mar 8 at 5:02
I don't have space to save a screen shot :( –  RED Mar 8 at 5:03
is there any possiblities to take the screenshot by mobile and upload it here. –  Avinash Raj Mar 8 at 5:06
Avinash, can you please let me know of what thing I should take a screenshot of. I don't what is gparted and what it is used for. I am some how able to install packages but not able to add any file anywhere. –  RED Mar 8 at 5:10

To increase the size of /dev/sda6 root partition,

  • Boot Ubuntu live disk and click on try Ubuntu option on startup.Now open gparted partition Editor from dash.And make sure that all the partitions are unmounted.

  • shrink /dev/sda3 by right-clicking on it and select Resize/Move option.

  • After shrinking, the unallocated space will be created just below to the /dev/sda3 partition.

  • Now right-click on the extended partition and select Resize option to add up the unallocated space by extending the dragger.

  • Unallocated space will comes under extended partition(just below to the /dev/sda5 partition.

  • Rightclick on the /dev/sda5 partition and select Resize/Move option.Move the dragger to extreme right and then click on Apply,so that the unallocated space comes just below to the /dev/sda5 partition.

  • Now you can be able to extend your /dev/sda6 root partition.

I figured out the problem few days earlier,it was related to the hadoop log files which occupied enormous space. Just needed to clean those. I did increase my partition size. Your answer was useful to some extent. I did want to give a +1 but it requires me 15pts.Thanks for helping. –  RED Mar 13 at 23:20
@RED please post your comment as an answer.it will help others in future. –  Avinash Raj Mar 13 at 23:34

The problem was caused because of a log file taking up too much space on the disk. The file was found in the HADOOP_LOG_DIR. We can find it in /etc/hadoop/conf/hadoop-env.sh. Here while configuring we setup the HADOOP_LOG_DIR.

I found them using:
find / -size +100M -ls.

Just do an rm -rf /var/log/hadoop/ . If your HADOOP_LOG_DIR points to /var/log/hadoop/ else rm -rf that particular location.
