You should have ONLY a single one with everything inside it, especially true for the /dev, /proc, /run, /srv, /sys and /tmp which must be empty folders inside the rootfs /dev/sda1.
I presume that if you were looking at serial debug port, you would have seen that it stopped and failed trying to mount /proc because it doesn't exist inside your /dev/sda1.
this experiment shows that /tem , /SAVE and swap only are OK .
fdisk -l /dev/sda

rewite /etc/fstab

and
head /etc/apache2/apache2.conf

<VirtualHost *:80>
ServerName s---------------.mydns.jp
DocumentRoot /var/www/d1
</VirtualHost>
----
ln -s /SAVE/d1 /var/www/d1
and more
/proc , /sys and /dev is very small , and /run is small ( in banana pi M1, 580 kB )
the work is left to sd card .
the work /tmp , swap and www is left to hard disk .
namely
sd card's burden becomes less .
i expect sd card gets longer life time .

Why are you still having "/dev/mmcblk0p2 /" and "/dev/sda1 /SAVE" in the /etc/fstab of the /dev/sda1 ?
Is your goal really having the sub drive as a primary root or as a second disk ?
RE: how to use USB hard disk as /(root) - hatahata - 07-01-2016
now
i give up to use hard disk as root , becasue of /boot/uEnv.txt in spite of your kind advice .
so use hard disk as swap , tmp and /SAVE( www files and /home/debian/SAVE folda lives in this folda by ln -s )
anyway
/etc/fstab

my banana pi M1 has sata interface and sata hard disk and use sata hard disk as root .
(/dev/sda1 236235700 84716984 139518556 38% /)
in this case the result is next

RE: how to use USB hard disk as /(root) - lenny.raposo-pine64.pro - 07-01-2016
just use ext drive for rootfs
BTW I will have rootfs for debian (Mate and Base Headless) available for download in the next couple of hours

thanks .
i am willing to downlod it .
*** now ( several days ago) ***
about ubuntu of pine64
firefox not OK
no chrome
about arch linux of pine64
cannot run firefox
cannot watch URL by chrome
debian is excellent for pine64 users .
RE: how to use USB hard disk as /(root) - hatahata - 07-01-2016
acording to martinayotte's kind advice . i can run root as hard disk drive .
1) rewrite
cat /boot/uEnv.txt
console=tty0 console=ttyS0,115200n8 no_console_suspend
kernel_filename=pine64/Image
initrd_filename=initrd.img
optargs=disp.screen0_output_mode=720p60
ethaddr=36:c9:e3:f1:b8:05
root=/dev/sda1
2)do next script clone-to-HDD.bat
Code:
ntpd -s
date
echo '--------------------'
mkdir -p /ma1
umount /ma1
mount /dev/sda1 /ma1
df
echo '--------------------'
read X
echo $X
cd /ma1
mkdir -p bin etc home lib opt root sbin srv usr var
for x in /bin /etc /home /lib /opt /root /sbin /srv /usr /var
do
rsync -avHx --delete $x/ /ma1$x/
done
for x in boot dev media mnt proc run sys tmp
do
rm -rf /ma1/$x
done
cd /ma1
mkdir -p boot dev media mnt proc run sys tmp3) rewrite /ma1/etc/fstab
# <file system> <dir> <type> <options> <dump> <pass>

#/dev/mmcblk0p2 / ext4 defaults,noatime 0 1

4)reboot
then

if i want to sd card only , i only rewite /boot/ /boot/uEnv.txt .
if i want to hard disk drive as root , i only rewite /boot/ /boot/uEnv.txt .
thanks !
pine64-image-debianbase-310102bsp.img is great .
now we run pine64 as server
