Raspberry Pi post-install grow partition question

I just downloaded the latest Raspberry Pi image (thankks Matthias!) and installed it on a 16Gb MicroSD card. My original intention was to use it with the new Raspi Model B+ but I see this is a work in progress, so I'm using it on a spare Model B.

So, what I noticed after the DD was complete I was left with a 150Mb and a 2Gb partition, which meant that I had about 13Gb wasted space. I used gparted on my Linux box to grow the 2Gb partition to fill the MicroSD card and /dev/root now says that I have a 15Gb partition with 13Gb free.

Is this the right/acceptable way to do this?

edit: on a Raspbian-based system you'd normally do this with raspi-config, but this is my first Arch install and I don't think it's supplied with that.

Hi,
yes raspi-config is not supplied on the archLinux. It is too bad, I think.
After you used gparted, did you do a resizefs ? I recommend to do that on a 2nd Linux computer, not directly from the RPi image you are running on.

resize2fs <parition-name>

see: [www.microhowto.info]

As an alternative, you can create an additional partition to use the spare space. (if wanted, I write a howto)

best regards

Resize2fs? Errr, no. I'll check this out and make sure everything starts correctly. Thanks for the info!

Just a quick followup - I checked the resized partition with resize2fs on my (other) Linux box and it reported that there was "nothing to do". FYI, I previously ran gparted on the other Linux box, not on the Raspberry Pi, so it seems to have worked without problems (so far).

Thanks for your help Matthias.

you can use fdisk -l and copy start sector of /dev/sda2 when delete it and make new again, answer all press enter except one - paste start secret of second partition what you copy previously. when save changes by pressing 'w'. then use resize2fs /dev/sda2

secret* not, sector )
