hi all . i use dietpi on odroid-c2 by cloning sd card’s root to hard disk .
i do this cloning on running diet pi .
now 2.5 inch hard disk drive is root .
\
- rewrite /boot/boot.init
setenv bootargs “root=UUID=83b7a780-6e17-4852-a847-459cef9db955 rootwait ro ${condev} no_console_suspend hdmimode=${m} m_bpp=${m_bpp} vout=${vout} fsck.repair=yes net.ifnames=0 elevator=noop disablehpd=${hpd}”
83b7a780-6e17-4852-a847-459cef9db955 is obtained by blkid /dev/sda1
-
may be unnesesary , becase /DietPi/boot.ini overwrite /boot/boot.init
\
-
rewite /DietPi/boot.ini equally 1)
-
do next script
mkdir -p /ma1
umount /ma1
mount /dev/sda1 /ma1
df
read X
echo $X
for x in dev mnt proc run sys tmp
do
rm -rf /ma1/$x
mkdir -p /ma1/$x
done
cd /ma1
mkdir -p DietPi bin boot etc home lib opt root sbin srv usr var
for x in bin boot etc home lib opt root sbin srv usr var
do
rsync -avHx --delete /$x/ /ma1/$x/
done
for x in dev mnt proc run sys tmp
do
rm -rf /ma1/$x
mkdir -p /ma1/$x
done
4) rewrite /ma1/etc/fstab
/dev/mmcblk0p2 / ext4 defaults,noatime,discard
→
/dev/sda1 / ext4 defaults,noatime,discard 0 1
reboot
then
df

i get big hard disk drive if sda1 is 250GB ore more .
now i run dietpi as big server , for example apache . 
regards
perhaps this method may be ok on cloning sd card .
it is sad that hard disk will be destroyed .
so i clone /dev/sda (USB hard disk) to /dev/sdb (USB hard disk)
boot by /dev/sda
- imprtant
rewrite /DietPi/boot.ini by doing ’ blkid /dev/sdb1’
\
- shell sctipt
mkdir -p /mb1
umount /mb1
mount /dev/sdb1 /mb1
df
read X
echo $X
for x in dev mnt proc run sys tmp
do
rm -rf /mb1/$x
mkdir -p /mb1/$x
done
cd /mb1
mkdir -p DietPi bin boot etc home lib opt root sbin srv usr var
for x in bin boot etc home lib opt root sbin srv usr var
do
rsync -avHx --delete /$x/ /mb1/$x/
done
for x in dev mnt proc run sys tmp
do
rm -rf /mb1/$x
mkdir -p /mb1/$x
done
then halt , remove only /dev/sda , and boot

about 120GB is available .
we donot need rental server if we have dietpi which runs on hard disk ( sd card is only starter )
64bit can use over 4GB memory .
odroid-c2 has only 2GB , so i realized it by SWAP .
now
