LILO+RAID1 problem pri zapise bootsektora

Zdravim,
takze najnovsie som vyskusal:
- v BIOSe som nastavil disky napevno
- v RAIDe je stale /dev/hda1 a /dev/hda2
- zapisal som bootsektor do /dev/md0
- navyse som zapisal (pri tej istej konfiguracii) bootsektor do /dev/hda
a /dev/hdb ( lilo -b /dev/hda ; lilo -b /dev/hdb)
Nic sa nezmenilo, chyba stale ostava.
Otazka do plena:
Myslite si, ze je naozaj mozne bootovat z RAIDU (myslim teda bootovanie
z jedneho disku, na to prave chcem ten raid, ze ak jeden disk odide, aby
som system natiahol aspon z druheho) iba ked su disky na roznych IDE
kanaloch? ( t.j. napr hda a hdc)? Ked nic ine nepomoze, tak to
samozrejme skusim, ale zda sa mi to take 'nepekne' riesenie,
principialne by to malo ist ... V praxi to samozrejme bude inak, ale
zaujima ma, preco to nejde.
Ak by islo o odobratie /dev/hdb1 z /dev/md0 a pridanie ho tam ako
/dev/hdc1, je na to nejaka sikovna finta, napr. hodit jeden disk(hdb)
ako failed, prehodit ho na druhy kanal (hdc) a nechat ho pripojit a
zosyncovat ako novy ... Alebo musim ten RAID zrusit, vytvorit novy a
prekopirovat tam udaje? Skusal som hotraidremove, ale ten tvrdi, ze hdb
je busy (comu sa samozrejme nedivim ;) ). Mam teraz kopec prace a nemam
cas (ani energiu) citat manualy, takze ak by nejaka dobra dusa mala
prave teraz nejaky dobry napad, bolo by to fajn. Ak nie, tak co uz,
nejako si poradim ;)
