Hallo,

die autodetection unseres Software RAID1 will nicht so ganz funktionieren. Die beiden Platten hängen an sowas hier:

0000:00:1f.1 IDE interface: Intel Corp. 82801EB/ER (ICH5/ICH5R) Ultra \ ATA 100 Storage Controller (rev 02) 0000:00:1f.2 IDE interface: Intel Corp. 82801EB (ICH5) Serial ATA 150 \ Storage Controller (rev 02)

Ein manuelles Aktivieren funktioniert super mit:

fsr:/usr/src/linux-2.6.11# mdadm --assemble --auto /dev/md0 /dev/sda1 /dev/sdb1 mdadm: /dev/md0 has been started with 2 drives.

Die Partitionen der beiden Teile des Arrays sind mit Typ 0xfd markiert:

Disk /dev/sda: 80.0 GB, 80026361856 bytes 255 heads, 63 sectors/track, 9729 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes

Device Boot Start End Blocks Id System /dev/sda1 1 9729 78148161 fd Linux raid autodetect

Beim booten sagt dmesg u.a. folgendes:

Kann es sein, daß die Erkennung der Platten fehlschlägt und deswegen das RAID nicht konstruiert werden kann?

Tschau,
