Hi Dennis,
sorry about the /dev/mdstat (I was in a hurry).
Hmm, the script should work....
There's something fishy about your md0 and hda1/hdc1. According to all
logic hda1 should be (hd0,0)...
Ok, I've got 1 machine running with 2 disks (raid1 using libata) and 1
with 4 disks, also running with libata. I haven't tried using ide for
raid.
I'll have to install 1 machine and try it out.
I'll get back to you.
Regards,
Rickard
