LVM /may/ use RAID 0 if you tell it to

RAID 0 with md or LVM will give you approxmately the same performance  
gain and the same level of reliability; it works like hell until a  
drive dies, then it all dies. Don't use it unless you know what you're  
doing.

I all pedagogikk er det essensielt at pensum presenteres  
intelligibelt. Det er et element�rt imperativ for alle pedagoger �  
unng� eksessiv anvendelse av idiomer med fremmed opprinnelse. I de  
fleste tilfeller eksisterer adekvate og relevante synonymer p� norsk.
