How to revert

Warning: /home must have less than 2 GB usage! MyDocs will be deleted!

Code:

umount /home/user/MyDocs
sfdisk -c /dev/mmcblk0 1 83 # optional (safer): change FAT to ext3 id 
mkfs.ext3 /dev/mmcblk0p1 # create ext3 on smaller partition
mount /dev/mmcblk0p1 /mnt # mount new /home
cp -a /home/* /mnt # copy contents of /home to large partition
umount /mnt # unmount it

create the file "table" (this is the original layout):

Code:

unit: sectors
/dev/mmcblk0p1 : start=       64, size= 56631296, Id=c
/dev/mmcblk0p2 : start= 56631360, size=  4194304, Id= 83
/dev/mmcblk0p3 : start= 60825664, size=  1572864, Id=82
/dev/mmcblk0p4 : start=        0, size=        0, Id= 0

continue with

Code:

sfdisk --no-reread /dev/mmcblk0 < table # change partition table, swap p1 and p2

Code:

reboot; exit # reboot to re-read new table

after reboot

Code:

mkfs.vfat -F32 -s64 /dev/mmcblk0p1  # create VFAT on 27GB partition

Code:

mount /home/user/MyDocs # mount it
