Hi All I have a issue where my system wouldn't login or startup properly. I checked the hard drive space to find the below.

matthew@Kronos:~$ df -h

Filesystem                   Size  Used Avail Use% Mounted on

/dev/mapper/Kronos--vg-root  214G  203G     0 100% /

none                         4.0K     0  4.0K   0% /sys/fs/cgroup

udev                         7.8G  4.0K  7.8G   1% /dev

tmpfs                        1.6G  928K  1.6G   1% /run

none                         5.0M     0  5.0M   0% /run/lock

none                         7.8G  4.0K  7.8G   1% /run/shm

none                         100M  8.0K  100M   1% /run/user

overflow                     1.0M   36K  988K   4% /tmp

/dev/sda1                    228M   55M  161M  26% /boot

zeus                         1.8T  1.3T  540G  71% /zeus

How do I fix this 100% full, I do not have a bigger hard drive to give it, am I stuck with having to buy a bigger drive for it? I'm fairly new to ubuntu and linux so please provide full command line commands I need to use.

Thanks in advance.

I have found the issue! Drilling down into the files using:

sudo du -a /home | sort -n -r | head -n 10

Shows the top 10 files taking up the most space, two of the biggest was .xsession-errors and my downloads folder. After going to the directory and using rm -f on the folders my /home is now only 6.1G!

Filesystem                   Size  Used Avail Use% Mounted on

/dev/mapper/Kronos--vg-root  214G  6.1G  208G   3% /

none                         4.0K     0  4.0K   0% /sys/fs/cgroup

udev                         7.8G  4.0K  7.8G   1% /dev

tmpfs                        1.6G  912K  1.6G   1% /run

none                         100M   20K  100M   1% /run/user

/dev/sda1                    228M   64M  152M  30% /boot

zeus                         1.8T  1.3T  538G  71% /zeus

Thanks to all that helped me to narrow down the issue and resolve it.
