SW RAID

[Milan Roubal]

je to v RAIDu, normalne ho to odpojilo a pripojilo
hot-spare disk, jak poznam jestli linux keca a nebo
ten disk skutecne miri do vecnych lovist? Kdyz se neco
podobneho objevilo posledne a linux mi odpojil jinej disk,
tak jsem to projel checkerem od vyrobce a nic zleho nenasel.
Ten disk se pak vratil do masiny a bezi dodnes.

Ten disk je na 99% nekolik hodin pred smrti, zalohuj, zalohuj, zalohuj,
dokud je cas.
