Shrinking the ext3 partition during the boot and creation of new partition


Hi,

Trying to shrink the existing partition of size 80GB, during the OS bootup (Fedora core 3). This is a root filesystem partition which I want shrink, to make way for CentOS to be install in the new partition.

For this I changed the initrd after mkrootdev command in the init file.

e2fsck -fy /dev/sda2

Resizing root device

resize2fs -f /dev/sda2 25G

After replacing the changed initrd and rebooting failed to get the partition resized. Are the steps being done are correct and is this feasible way to do this, since I want to avoid doing it in the rescue mode or using some bootable usb with os.

Hi saleem_ak,

I am not so sure what you mean by trying to shrink DURING bootup but....

When I want to re-size / change partitions I usually find Ubuntu Live CD pretty handy. It has GParted which is an easy to use GUI partition editor. I think there is also a specific GParted Live CD available. I'm sure if you Google Ubuntu or gparted you will find these.

Cheers,
Daniel.

What you've done should resize the partition. There's no need to mess with the initrd, it's not related.
