problem z mdadm - wyrzucanie dysku z macierzy

[Przemysław Backiel]

Witam,

mam taki problem z dyskami: WDC WD3200YS-01P  Rev: 21.0

albo nie wiem z czym :)

otóż, przy starcie, *zawsze* wywala mi dysk /dev/sdb2 z /dev/md1 ("/")

tak wygląda fragment dmesg'a

gdy po tym, dodam dysk /dev/sdb2 do /dev/md1
to smiga...
restart i znowu...

macierzy mam kilka:
/dev/md0 do /dev/md6
i tylko z /dev/md1 jest taki problem

any idea?
jak poszukać źródła problemu?
