Re: How to recover RAID-1 array when "./MAKDEV md" fails!?

[Florian Boelstler <euphoria@arcor.de>]

Hi,

I don't know about RAID-arrays and alike however I recently came across 
some messages on the german debian list.
I compiled the most important things here:

zeus:~$ tail -5 /etc/udev/links.conf
M md0           b 9 0
M md1           b 9 1
M md2           b 9 2
M md3           b 9 3
M md4           b 9 4

mdadm 1.9.0 has the "auto" option for the
mdadm.conf file. However it seems to be picky about the position
of that statement inside the conf file. So far, it has worked
for me only if auto=md was the last statement for the ARRAY
definition. Another problem: it seems that "DEVICE partitions"
in mdadm.conf doesn't properly detect all raid partitions.
I've replaced that line with the "old-style" def. Here my working
mdadm.conf:

DEVICE /dev/sda*, /dev/sdb*
ARRAY /dev/md0
	level=raid1
	num-devices=2
	UUID=........
	devices=/dev/sda1,/dev/sdb1
	auto=md
