View Full Version : [SOLVED] How to reassign the space of my HDD partitions?

September 23rd, 2011, 07:46 AM
Ok, I know there may be tons of threads with this question. But not all of us have the exact same partitions.

So, this is my case.

I have a 120GB HDD with 3 physical (primary) partions. From left to right:

dev/sda 16GB for root - dev/sda3 102GB for home - dev/sda2 2,5GB for swap

I realized that I used to much for root and swap, so I want to take from them and give it to home.
So at the end I would have 10GB for root, 1GB for swap and 109,5 for home.

But, I don't know if I could "damage" any files during the process. I understand that it can be done using Live GParted, which I have ready to use now, on a USB Stick.

But I'd like to read your thoughts on this matter.

Should I do it? Any precautions?

I never had any problems with GParted. Give it a go.
But be aware that you should do backups.
The only hint I can give is, let it do whatever it does. And don't touch it until it's done.

Should I do it? Any precautions?gparted is a partitioning tool and there is always a chance of something going amiss
when you use one. Back up your personals before using.
Open gparted and take a screenshot of it and post here. Use the paperclip icon and upload
to to your Message box. Easier to see what for you to move.
I have used gparted quite abit and have not had a bad moment but one never knows.
Just want to let you know that there is always a risk.

Just a final warning, but not for you to be too scared about.

The resizing takes a long time, and I mean a long time, possibly a few hours. The program runs a full fsck check on the partition prior to resizing, then does the resize, and finally does another full fsck check after the operation has been carried out. The last time I did it on a large and fairly full partition the whole job took nearly 5 hours, but this is on an old slow machine. Whatever you do, make sure you don't interrupt the operation, and if this is a laptop, use mains power.

that's why i said

let it do whatever it does. And don't touch it until it's done. :D

an interruption of the process could corrupt the whole filesystem.
You can imagine what happens afterwards ...

Thanks to all the replys.

I'll do my backup and then proceed.

I've heard that running a defrag software can help, should I do it? I don't know any defrag program for Ubuntu.

This is a pic of GParted, it's in spanish but I think that's not a problem


I don't know why is there 1MiB unassigned between dev/sda3 and dev/sda2...

defrag is merely a microsoft related fairy tale to soothe your mind.

linux filesystems don't need that.
AFAIK there is no one using one...

Be aware that after you have shrunk the / partition you will need to move it to the left of the /home partition in order to add it to /home.

Personally I'd not bother trying to resize swap but would just delete it and recreate a new one.

You'll likely need to right click and swapoff to do anything to the swap anyway.

Lastly -
Should I do it?that's up to you - but if you were me you'd not be bothering given the amount of space you've got free in /home :)

No need to give any warnigns - they've already been dealt with ...
