how to use USB hard disk as /(root)

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
---------------------------------------------------------------------------------------
Device Boot Start End Sectors Size Id Type
/dev/sda1 10487808 15730687 5242880 2.5G 83 Linux
/dev/sda2 2048 4196351 4194304 2G 82 Linux swap / Solaris
/dev/sda3 


 and 
rewite /etc/fstab
/dev/mmcblk0p1 /boot vfat defaults 0 2
/dev/mmcblk0p2 / ext4 defaults,noatime 0 1
/dev/sda1 /SAVE ext4 defaults,noatime 0 1
/dev/sda2 none swap sw 0 0
/dev/sda3 /tmp ext4 defaults,noatime 0 1



and
head /etc/apache2/apache2.conf

NameVirtualHost *:80

<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 ?

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
/dev/mmcblk0p1 /boot vfat defaults 0 2
/dev/mmcblk0p2 / ext4 defaults,noatime 0 1
/dev/sda1 /SAVE ext4    defaults,noatime                0               1    
/dev/sda2 none   swap    sw                             0               0
/dev/sda3 /tmp  ext4    defaults,noatime                0               1

when i want to return it to the beginning(sd card only system ) , i only rewrite /etc/fstab originally .
easy

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

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
If you like my work be sure to check out my site or wish to donate to the cause

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  tmp







3) rewrite   /ma1/etc/fstab
# <file system> <dir> <type> <options> <dump> <pass>
/dev/mmcblk0p1 /boot vfat defaults 0 2
#/dev/mmcblk0p2 / ext4 defaults,noatime 0 1

/dev/sda1 / ext4 defaults,noatime 0 1

/dev/sda2 none   swap    sw              0       0


4)reboot

then
df

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 Tongue
