Increase / filesystem

here is my current df -k

Filesystem 1K-blocks Used Available Use% Mounted on
/dev/sda3 6143268 281572 5549636 5% /
/dev/sda1 256667 35089 208326 15% /boot

/dev/sda5 4127076 170788 3746644 5% /var

the root has 6gb but we need to increase this to 8GB. Please let me know how i can do this?

here is my fdisk -l

/sbin/fdisk -l

Disk /dev/sda: 146.8 GB, 146814976000 bytes
255 heads, 63 sectors/track, 17849 cylinders

Well, first things first.. Back evernything up!

Pretty much all of the available choices are quite dangerous, and should be performed with the server in single-user mode.

To start with, use a tool like 'gparted' from a LiveCD (http://gparted.sourceforge.net/ or http://www.sysresccd.org/Main_Page).

This makes everything so much easier.

'gparted' is a GUI interface to the 'gpart' tool, which allows you to resize most filesystem types, including ext2/ext3.

As it is, you need to shuffle the filesystems around to amek enough space for 'sda3' to have an extra few GB of size.

If you don't want to use a tool like that, then you'll have to do it all manually with 'parted', and 'ext2resize' or 'resize2fs'. This can be quite complicated, and messy.

Hello!

/ (root) is impossible to increase without an externale tool.

Follow the previus advice.
GParted is a great tool for do this. Is like Partition Magic, but is free and linux-based.
Remember to backup all first!
