Resize galileo devkit image partition

I am trying to resize/increase the size of the root partition from 1.3GB to the size of my SD Card 8GB/16GB. I came across this post . But the steps mentioned in there dont work for me. When I do fsck.ext3 on the image file I get the following error

ext2fs_open2: Bad magic number in super-block

fsck.ext3: Superblock invalid, trying backup blocks...

fsck.ext3: Bad magic number in super-block while trying to open iot-devkit-201510010757-mmcblkp0-galileo.direct

...

My guess is that this is not a ext filesystem? How do I find out what filesystem it is? This is the url I used to download the image http://downloadmirror.intel.com/25384/eng/iot-devkit-201510010757-mmcblkp0-galileo.direct.xz http://downloadmirror.intel.com/25384/eng/iot-devkit-201510010757-mmcblkp0-galileo.direct.xz

Hey Rishabh - The absolute 100% easiest way is to use parted. I personally boot up a Fedora VM in Virtualbox and resize it using gparted. It takes seconds.

You piqued my curiosity, I checked and it looks like an ext3 filesystem.

root@galileo:/etc# df -Th

Filesystem Type Size Used Avail Use% Mounted on

/dev/root ext3 14G 1.3G 12G 10% /

devtmpfs devtmpfs 116M 0 116M 0% /dev

tmpfs tmpfs 116M 0 116M 0% /dev/shm

tmpfs tmpfs 116M 8.4M 108M 8% /run

tmpfs tmpfs 116M 0 116M 0% /sys/fs/cgroup

tmpfs tmpfs 116M 83M 34M 72% /tmp

tmpfs tmpfs 116M 24K 116M 1% /var/volatile

/dev/mmcblk0p1 vfat 50M 17M 34M 33% /media/card

What you should do is use DD to install it to the sd card. I use dcfldd because I like the output more, but you get the idea.

# on your laptop

sudo dcfldd if=~/Documents/intelGalileo/iot-devkit-201510010757-mmcblkp0-galileo.direct of=/dev/disk4 bs=8M statusinterval=4

Then run gparted on a linux machine or virtualbox to do the resizing.

Cheers,
