Increase HDD Space

I want to increase space allocated to mount / i.e sda3 . How do I do it? I am currently running arch in dual boot with Arch.

[araragi@araragi-pc ~]$ df

The question you are actually asking is: "How can I resize a filesystem", and the answer is: you resize the underlying partition and then grow the filesystem to fill it. You can use any partitioning software to alter the partition table on your drive, and then a tool for your filesystem to resize the filesystem. e.g., if you have an ext4 partition, you use resize2fs. Some tools will automagically call the filesystem tool for you. In any case, you should make a backup of your files before attempting to modify your partition table.

Re: Increase HDD Space

To add one piece of clarification to what WorMzy said, the whole process will need to be (or should be?) done from a "live environment", such as booting from a SystemRescueCD disc. The partition that is being resized will need to be unmounted, and you can't unmount "/"...

...but I'm not convinced you need to resize your root partition! I mean, I install software liberally, I have a 30 GB partition for Arch Linux, and it's still only 70% full. In a pinch, it is a simple process to move my pacman cache to a different larger partition, which would free up 3 GB (which is already super cleaned up).

So, what is the reason you want more space for your home partition?

Re: Increase HDD Space

Was this a typo?  Otherwise, why would you do this?

But as above, what is the actual problem?  You still have 12GB still free on your root partition: that's 3 times the size I use on my root partition.
