    Mára a ProHardver!/IT.News Fórum is nagylétszámú Linuxban jártas taggal büszkélkedhet. Nehéz szinteket felállítani egy olyan rendszer ismeretében, ami annyira sokrétű, hogy teljesen szinte lehetetlen megismerni minden egyes részét. Azt azonban mindenki tudja, hogy kezdő-e vagy sem. Elsősorban nekik szólnak az alábbiak, de érdemes mindenkinek elolvasnia, mint útjelző táblát.

    sziasztok!

    van egy raid0 tömböm, 2x3tb WDC WD3000FYYZ-05UL1B0. Szeretném, ha ez a 2 winyó, ha nincs semmi feladata, akkor sem kapcsolna ki. hdparm-al a következő utasítást kiadtam nekik:

    hdparm -B 255 /dev/sdb
    hdparm -B 255 /dev/sdc

    hdparm -S 0 /dev/sdb
    hdparm -S 0 /dev/sdc

    elvileg ezt nyugtázta is a gép,

    [root@wrouter ~]# hdparm -I /dev/sdb
