yes- this means that the superblocks are already there. try using
mkraid --really-force /dev/md1

this is possibly another problem. looks like you are not running a patched
kernel. better get the patch for your version: kernel 2.2.11-.13 use the .11
patch from ftp.XX.kernel.org/pub/linux/daemons/raid/alpha/ (where xx is your
country code)
if you are using 2.2.14 or higher, look at www.redhat.com/~mingo/
you will need to patch source and re-build/re-install kernel.
