Resizing the wubi partition in lucid

[durand]

Hi,

Is it possible to increase the size of an ubuntu partition installed via wubi? A friend of mine installed ubuntu this way but she needs more space. The method in the ubuntu wiki apparently doesn't work for 10.04. Is there an alternative?

Thanks!

See the instructions below, section 8.9:

Yeah, that method doesn't work in 10.04.

Sorry ... not a fan of Wubi; don't use it. Only trying to help.

Perhaps, if you (and other Wubi users) found a way to contact the Wubi providers, they would update their sadly-out-of-date documentation.

Thats ok, I appreciate it. I don't use wubi either but I might have to install it to see what works.

Thanks.

You can resize the root.disk. It's not strictly speaking a resize - you have to create a new bigger one and copy the data across (i.e. to make a 5GB disk 7GB, you need 7GB free space, not 2GB). It might be better to split the /home into a new virtual disk.

The problem with lvpm is that it requires grub-legacy due to the way the transfer to partition part works (or doesn't work anymore, to be precise). The resize part is fairly simple. I've just run a test on it and it works (I made my new.disk 5GB):

sudo -i
cd /host/ubuntu/disks
dd if=/dev/zero of=new.disk bs=1M count=5000
mkfs.ext4 -F new.disk  # use ext4 with new installs on 9.10 or later
mkdir /media/extra
mount -o loop,sync /host/ubuntu/disks/new.disk /media/extra
rsync -av --exclude '/sys/*' --exclude '/proc/*' --exclude '/host/*' --exclude '/mnt/*' --exclude '/media/*/*' --exclude '/tmp/*' --exclude '/home/*/.gvfs' --exclude '/root/.gvfs' / /media/extra
umount /media/extra
rmdir /media/extra
exit
#reboot to windows, rename root.disk to root.disk.old and new.disk to root.disk

Caution should be used getting someone to run commands as root or using dd and mkfs - but you could easily put it in a shell script.
