Root full on UBUNTU 14.04

Question

After installing some operating system updates my root partition is full. I'm a new user of UBUNTU so I'm sure this is an easy fix.

Answer 1

First find the directory that has used most of your hard disk space by running # du -sh /*.

Let assume it is /var dir.

Now you could add additional hard disk & create a brand new partition on it by running # fdisk /dev/sdb (here it is assumed the newly connected hard disk is /dev/sdb)

Let assume the created partition is /dev/sdb1 and it is formated with ext4 filesystem.

Now, let the system /var dir's mount point is to be that partition

• edit the /etc/fstab with your favorite editor (nano or vi)
• add the following and save it and reboot to see the effected changes
• /dev/sdb1 /var ext4 default 0 0
