RAID1 vs LILO

Sziasztok,

pár éve mdam-el összeraktam egy raid1-es arrayt, ami azóta is jól muzsikál. Anno teszteltem, ha lehúztam bármelyik hdd-t szépen bebootolt a másikról (és elindult a rebuild a spare diskkel). Most upgradelve lett a konfiguráció, gondoltam nem javítom meg azt ami nem romlott el és maradtam az eddigi eszközöknél: madm, raid1, lilo. De most csak akkor bootol, ha az sda bent van a gépben, egyébként nem (a bios sda, sdb, sdc, sdd sorrenddű bootolásra van állítva).
Szerintetek mi lehet a hiba?

Itt van a felépítés:

OS:

# uname -a
Linux edax 2.6.24.2_core2_edax #4 SMP Mon Feb 18 10:46:31 CET 2008 x86_64 x86_64 x86_64 GNU/Linux

A kernelben benne van minden raid0/1/10-hoz szükséges stuff.

Partitions:

Köszi, hogy eddig elolvastad és előre is a segítséged, de ha kérhetlek, ne javasold, hogy használjak grubot :)

Üdv, Ádám
