========== WARNING ==========

# Info about partitions:
/dev/md0 - Swap (512MB)
/dev/md1 - Rootfs (5GB)
/dev/md2 - User data (All unused space, not mounted by default)

======== INSTALL =========
Just flash "debian-jessie-firmware" in webgui.
Or use Recovery

# Crazy way to run WD recovery:
flash_eraseall /dev/mtd1

When you see blinking HDD led - press and hold reset button to format all HDD's inside device.
* Blinkng: blue > hdd_red_1 > hdd_red_2 > hdd_red_1 > hdd_red_2 > off (1 sec interval. Hold reset button until its stop blinking.)

If you see both red (purple) hdd leds - something went wrong. Connect to WDMC via Telnet and repair (Or prepare disks manually).


======= ADD 2nd disk to exist raid =======
# Format HDD (Change /dev/sdb to /dev/sda if need):
parted --script /dev/sdb "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"
# And add it to exist raid:
mdadm --manage /dev/md0 --add /dev/sdb1
mdadm --manage /dev/md1 --add /dev/sdb2
mdadm --manage /dev/md2 --add /dev/sdb3

# So, if you need disconnect one of HDD:
mdadm --manage /dev/md0 --fail /dev/sdb1
mdadm --manage /dev/md1 --fail /dev/sdb2
mdadm --manage /dev/md2 --fail /dev/sdb3
# Then - you can extract this drive from WDMC.

# If you need RAID-0 (Stripped):
# Warning! Data partition will be erased!
umount /dev/md2
mdadm --stop /dev/md2
mdadm --create --force /dev/md2 --raid-devices=2 --level=raid0 --run /dev/sda3 /dev/sdb3


======= OMV SETUP =======
# Connect to device via SSH
# Default SSH login/password: root/mycloud

# Install latest OMV (v.3.x.x, "erasmus")
echo "deb http://packages.openmediavault.org/public erasmus main" > /etc/apt/sources.list.d/omv.list
echo "127.0.1.1       wdmc.lan wdmc" >> /etc/hosts
apt-get update
apt-get install --force-yes openmediavault-keyring
apt-get update
apt-get install openmediavault
# choose "none", "yes", "standalone"


# Default OMV login/pass is: admin / openmediavault
# Warning: create network interface in webgui or you loose network connection after restart!
# "Mount" data partition (/dev/md2) as "User data".
# Configure all other things.
# Profit!

======== REVERT =========
dd if=/dev/zero of=/dev/mtdblock1
reboot -f

# After this WDMC runs in "Rescue" mode. Go to webgui and upload original firmware file (.bin)

======= TEMP: DISABLE POWER LED =======
add this to /etc/rc.local:

echo -n -e \\xfa\\x03\\x01\\x00\\x00\\x00\\xfb > /dev/ttyS1

# Notes:
# System ready/OK: \\xfa\\x03\\x01\\x00\\x00\\x00\\xfb
# Led on: "\\xfa\\x03\\x06\\x01\\x00\\x01\\xfb"
# Led off: "\\xfa\\x03\\x06\\x00\\x00\\x01\\xfb"
# Led blink: "\\xfa\\x03\\x06\\x02\\x00\\x01\\xfb"
# Enable WOL function: "\\xfa\\x03\\x0a\\x01\\x00\\x00\\xfb"
# Disable WOL function: "\\xfa\\x03\\x0a\\x00\\x00\\x00\\xfb"
# Hard shutdown: "\\xfa\\x03\\x03\\x01\\x01\\x14\\xfb"
