If there still is nothing listed in 'ls /dev/md*', you could create them by hand, as many as you need: root@host:/# mknod /dev/md0 b 9 0 root@host:/# mknod /dev/md1 b 9 1 [...] (creating /dev/md0 as a 'B'lock device with major device number 9 and minor 0) Oh, and don't forget to assign proper access permissions... I'd suggest root@host:/# chown root:disk /dev/md* root@host:/# chmod 0660 /dev/md* If the problem persists after the devices are present, please report back - but "no such file or directory" usually indicates that the device node is missing, not the underlying driver. :-) Jan -- Jan C.
