The device names of 'SCSI' devices are prone to change with changing system configuration. If something disappears or is added, all the names could change, and this will cease to work. I would strongly recommend putting UUIDs in there. echo 'DEVICE /dev/sd[a-l]' > /etc/mdadm/mdadm.conf mdadm -Ds | grep -v devices >> /etc/mdadm/mdadm.conf NeilBrown - To unsubscribe from this list: send the line "unsubscribe linux-raid" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
