====== QNAP drive ======
Mounting a wonky (RAID) drive from a QNAP NAS on another machine.

Brief list:
  - apt-get install mdadm
  - Reboot, with drive plugged in 
  - Check lvdisplay that drive is present
  - mount -o ro /dev/vg289/lv2 /mnt/roms
  - cd /mnt/roms/ROMs/
  - rsync -avze ssh . admin@kargath:/share/CACHEDEV1_DATA/ROMs/

Other stuff:
  * Check /etc/mdadm/mdadm.conf on original and target machines for the same drive ID
  * Or, if mdadm.conf doesn't exist: mdadm --examine --scan > /tmp/mdadm.conf
