Here are some pics of the RAID configuration: http://www.knuka.org/raid1.jpg http://www.knuka.org/raid2.jpg For me it seems that the drives are initialized and virtual disks setup, so it is not a hardware configuration issue? I also received confirmation from the vendor that the controller is "LSI 1068E". Should this controller be supported by CentOS5.5 without a driver disk? Regards, Peter Regards, Peter
