Niestety nie mówi za sympatycznie  ;-/
Dziwne, że smart mi tego nie wypisał wcześniej  ;-/
W serwerze 2 dyskowym (raid1) poleciały mi oba na raz.
Jeden wymieniłem, dwie partycje się odbudowują (md1 -boot i md3 - dane), 
systemowe nie chce (md2).
Pytanie co z tym dalej zrobić ??
Jest jakaś metoda wymuszenia odbudowy ??
disk dupem sklonowanie ??
Stawiać wszystko od nowa i przenosić usługi ?
