Resizing Linux image for 200GB SD card

Hi rabia7,

the main problem is that the altera layout of the image has the linux rootfs located in the middle.

The easiest way out of this is to

- copy /dev/sdc2 into am image file

umount /dev/sdc2

dd if=/dev/sdc2 of=rootfs.img

- use fdisk /dev/sdc

- delete partition 2

- create new partition 2 behind partition 1 up to the end of the sd card

- copy the image back to /dev/sdc2

dd if=rootfs.img of=/dev/sdc2

sync && sync && sleep 1

- resize file system in /dev/sdc2 to full size of partition

e2fsck /dev/sdc2

resize2fs /dev/sdc2

This way you loose 4.3 GB but you gain nearly 200 GB.

You can, of course use the same trick to move the FAT32 partition to sector 4096 and use the whole rest for Linux.

(I copied the commands from some of my scripts. They mostly need to be run as sudo. Maybe I missed some detail, so be careful ;-)

good luck
