sziasztok! a következő problémám lenne, ami igazából nem is probléma.

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
