Hi,

I'm trying to add a partition to a raid 1 set that I built with a "missing"
partition.  But mdadm won't let me add it to md0, or remove it

platinum:~# cd /
platinum:/# mdadm /dev/md0 -r /dev/hda1
mdadm: hot remove failed for /dev/hda1: No such device or address
platinum:/# mdadm /dev/md0 -a /dev/hda1
mdadm: hot add failed for /dev/hda1: Invalid argument

I don't get this.  I had it all working, then I tried to update my kernel to
2.6.5, then the machine wouldn't boot without my interaction.  So now when
I boot to the old (working) kernel.  I'm missing on partiion on
/dev/md0.

I'm running on debian

Thanks
Jay
