[K12OSN] Another upgrade question

I think my hda is going bad.  It's got everything except /home on it and 
fsck and smartd show up clean on it so far.  What's the easiest way to 
clone that drive onto another drive?  is there some dd magic that will 
just copy straight across and make the new one bootable and everything?  
I'm running LVM2.  I've looked a bit at the documentation and it almost 
looks like there would be a way using LVM to add a second drive and then 
remove the first, but I'm a novice at LVM. 

FYI - my problem is that my server crashes every night during the wee 
hours of the morning.  Each morning I am greeted by a kernel panic 
message.  Something about fs/dcache and a few other messages that I 
don't understand.  It is in my freezing cold basement, and the case it 
is in has some extra holes from CDROM bays that haven't been plugged.  
Has anyone heard of 40 degree temperatures crashing servers when they 
are idle?  I'm not positive, but I think I'm detecting a corelation 
between how cold it is at night and how early in the night my server
