It was created after installation
# vi /etc/raidtab
# fdisk /dev/sdc2
# fdisk /dev/sdd2
# mkraid -R /dev/md0
# mkfs -j /dev/md0
# e2label /home /dev/md0

I think you are right, question is like why it works with /dev/md0
and not with the disklabel which well works when I have already booted
the system. If I reboot the disklabel fails.

I did do a mkinitrd :) this just puzzles me. I might try to do a raidsetup
with Anaconda and see if that works with disklabels or not. Thanks for
your suggestions!
