Any time I've seen this problem pursued (as opposed to throwing up hands and just using partitions) it was found to be the motherboard (well, the UEFI bit) deciding that a storage device with no GPT or MBR needs an empty GPT adding to it. This corrupts md arrays on whole devices. Example: http://forum.asrock.com/forum_posts.asp?TID=10174&title=asrock-motherboard-destroys-linux-software-raid Is it possible that this is happening to you? If not, once again I urge you to go on over to linux-raid list and describe what's happening. Cheers, Andy -- https://bitfolk.com/ -- No-nonsense VPS hosting
