It's optional. There are ways to monitor an array using mdmon, but I haven't used it. If the partition types are RAID Auto (fd), then the kernel will read the metadata from partitions without the .conf file (format 0.9 only). I think the .conf file is only needed if the partition is not marked or advanced features are desired. When I look at the mdadm man page, it is 1766 lines long. One thing I see there is: echo 'DEVICE /dev/hd*[0-9] /dev/sd*[0-9]' > mdadm.conf mdadm --detail --scan >> mdadm.conf This will create a prototype config file that describes currently active arrays that are known to be made from partitions of IDE or SCSI drives. This file should be reviewed before being used as it may contain unwanted detail. -- Bruce -- http://linuxfromscratch.org/mailman/listinfo/blfs-dev FAQ: http://www.linuxfromscratch.org/blfs/faq.html Unsubscribe: See the above information page
