CentOS a divne LVM/CentOS installation strange LVM partition

SK 

Pokial sa snazite nainstalovat CentOS a nebodaj spravit softwarovy RAID medzi dvoma diskami a v rozdelovaci diskov vidite miesto dvoch diskov len jednu divnu LVM particiu s ktorou sa neda pohnut tak vedzte, ze pri boote musite do konzole pripisat nasledovne:
linux nodmraid

A kedze CentOS nema vlastny zoznam mirrorov a musite rucne vypisovat odkial si ma netinstall stiahnut potrebny image, tak tu je jeden ktory sa zda byt celkom rychly:

http://mirror.karneval.cz/pub/centos/5.3/os/x86_64

do koloniek musite vypisat najskor mirror.karneval.cz a do druhej zvysok cize /pub/centos/5.3/os/x86_64.

If you want install CentOS plus configure software RAID and you still see in partition manager only one strange LVM partition without any posibbility to change it and your hair is standing up (like my was), continue reading. In boot console write this:
linux nodmraid
And done :) CentOS doesn`t have preset mirror (or posibility to choose one), you must write an URL to installator. In Czech republic I`m using http://mirror.karneval.cz/pub/centos/5.3/os/x86_64. In first textbox write mirror.karneval.cz, in second /pub/centos/5.3/os/x86_64. I don`t understand that policy, because this is a huge security problem, but maybe there is some reason :) Fortunately I`m using Debian.
