How can I get lilo to work? Funny is I have a working lilo boot
sector, but I cannot create a new one. I have no idea what I've
changed...

Is there a limit how many md devices I can create? My /dev contains
md0 to md15. I'd like to leave some gaps between each device to be
able to insert another later (to steer the resync order).
E.g.:
/dev/md3 /boot
/dev/md6 /

/dev/90/home
Is that possible? I created
I tried the 2.3.99-pre8 Kernel, but I cannot load the raid1/5 module.
I can only load the raid0 module.

I'm playing a bit with Linux RAID and now I have a question about the
power supply. When I use 3 or 4 modern IDE drives I guess they will
consume a lot of energy.
Do I need a special power supply like 300 W or what are you using?
What about "IDE power down when idle"? Can this blow up the power

You don't want to use "power down when idle" on drives in a RAID...
Why not? I think about power down after

A high capacity PS is always good to have, esp. in a high uptime
box. Having that extra wattage available can prevent power dips
from making things flake out.
What about the

Why not? I think about power down after e.g. 30' idle time. Not
after a few seconds... What's the Problem with RAID? Does it mark
all disks as bad if they don't come up fast

Or is this handled under a different class of RAID (ignoring things
