Simple question: Growing an ext2 partition

dogsbody · 08-16-2004, 07:31 PM

Hi,

I wonder if you can help me, I feel I am so close but so far

I had a 20Gb drive in my machine with Slackware 9.1 which I wanted to replace with a new 120Gb drive. This bit went fine, I installed the 120Gb drive, booted into knoppix, did a "dd if=/dev/hda of=/dev/hdb" and removed the old 20Gb drive.

This works great, boots straight up and no data lost

but obviously I have the old partition sizes...

Code:

Disk /dev/hda: 120.0 GB, 120034123776 bytes
255 heads, 63 sectors/track, 14593 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes

   Device Boot      Start         End      Blocks   Id  System
/dev/hda1               1          63      506016   82  Linux swap
/dev/hda2   *          64        1184     9004432+  83  Linux
/dev/hda3            1185        2491    10498477+  83  Linux

So now I just want to grow /home (hda3) into all that lovely fresh space :-)

I must be googling for the wrong things, could anybody please tell me how to do the last bit??

Thank you very much in advance.

First the disclaimer. Except resizing my NTFS partition to install Linux i have never done this. Usually if I add HD space to a system I mount the new drive to replace an existing partiion or partitions.

OK, now that we have that over with the first answer that comes to mind is parted. http://www.gnu.org/software/parted/

There are also a few other projects out there (goggled for "resize ext2 partition", already knew about parted.) but parted seems to be the mainstay for this kind of thing outside of commercial software.

Yeah, I saw a lot of talk on "parted" but i can't get it to compile!!

I have no idea why.

I think I'm getting somewhere with using fdisk to create a bigger partition and then installing "ext2resize" to do the resize.

So far so good.

Thank you for the help.

If you don't mind using precompiled packages parted is available on linuxpackages.net. But ext2resize should do the job as well.

EDIT: If you have the official CD set it is also in the extras directory on CD3 it seems.

You can also get an official package here .
