Witam,
Problem z uruchomienie softraid (mdadm) RAID1. Mam 2 identyczne dyski z
partycjami:

Utworzyłem i zsynchronizowałem macierze.
Wygenerowałem nowe initrd:

Po restarcie systemu mam komunikat: md1 unknown partition table,
System nie wstaje :(
Walczę z tym od rana i poległem. Robię sobie przerwę pisząc tego maila do
Was z nadzieją że może ktoś wskaże mi co robię źle ?
Proszę o pomoc bo dostaję od tego białej gorączki.
