Created a new Samba server using two 2 terabyte drives. Ubuntu 12.04.3 LTSx64. On system reboot files appear to be missing. On system shutdown and start everything appears normal. Or so I think. However mdadm I believe shows errors. First time attempting a raid server. This is what I get on shutdown and start.
