===============================================================
>> Short howto:
>> For RAID setup (2nd disk can be added later):
# !!! Replace "/dev/sda" to WDMC disk !!!
# Run it for both disks if you need raid and replace "missing" in mdadm command to 2nd disk (/dev/sdb)
parted --script /dev/sda "mklabel gpt \
mklabel gpt \
mkpart primary 0% 512MB \
mkpart primary 512MB 4096MB \
mkpart primary 4096MB 100% \
set 1 raid on \
set 2 raid on \
set 3 raid on"

mdadm --create /dev/md0 --level=1 --metadata=0.9 --raid-devices=2 /dev/sda1 missing
mdadm --create /dev/md1 --level=1 --metadata=0.9 --raid-devices=2 /dev/sda2 missing
mdadm --create /dev/md2 --level=1 --metadata=0.9 --raid-devices=2 /dev/sda3 missing

# For add 2nd disk later (On wdmc)
# Format disk and run this:
mdadm --manage /dev/md0 --add /dev/sdb1
mdadm --manage /dev/md1 --add /dev/sdb2
mdadm --manage /dev/md2 --add /dev/sdb3

>> Mount partitions and upload rootfs (Already include kernel):
mkdir /mnt/root
mount /dev/md1 /mnt/root

>> Upload rootfs archive to this partition and unpack:
cd /mnt/root
tar xvf jessie-rootfs.tar.xz

>> Use USB-Drive: Format it to FAT32, create folder named "boot" and upload inside uImage and uRamdisk
>> Plug USB-Drive to WDMC, power on. If boot success - upload kernel to internal flash:
cd /boot (Or any other folder, where placed uImage and uRamdisk)
dd if=/dev/zero of=/dev/mtdblock1	# "No space" errors - normal.
dd if=/dev/zero of=/dev/mtdblock2
dd if=uImage of=/dev/mtdblock1
dd if=uRamdisk of=/dev/mtdblock2

>> OR: U-Boot command (tftp method + UART):
# (You can use "recovery" archive from WDMC Gen1 - its contains preconfigured tftp server for Windows)
set ipaddr 192.168.0.2; set serverip 192.168.0.1; tftp 1200000 uImage-4.8.6_ex2u tftp 2000000 uInitrd; bootm 0x1200000 0x2000000
