Re: "Swap area shorter than signature indicates"

Everything seems setup correctly.  What's in /proc/swaps?

Probably you initialized the swap partitions before creating the raid
array (on /dev/sda5 and/or /dev/sdb5).  Software raid steals a bit of
space from the device so your resulting mirror is smaller than each
device.  Make sure first that you aren't using it (swapoff /dev/md1),
then do a mkswap /dev/md1 to reinitialize the array as swap.
