Do you still use this setup, and do you still have the issue? What is in your /etc/crypttab? Do you perhaps need an offset to preserve mdadm metadata? For example, I have 'offset=8' for an encrypted swap partition, but it is not an mdadm device: cryptswap /dev/mapper/optivg-swap /dev/urandom swap,offset=8,cipher=aes-cbc-essiv:sha256,size=256,hash=ripemd160 The last suggestion is just a guess.
