Bug#294404: udev and mdadm mess

[Dimitri Puzin]

Package: mdadm
Version: 1.9.0-1
Followup-For: Bug #294404
Hello,
I've been trying to setup md-raid on a system using udev and ran 
across the problem described in this bug. AFAICS udev won't 
create device nodes as long as there is no device initialized in 
the kernel. OTOH mdadm insists on having a device node for the 
RAID before it is built. So far my understanding of the problem. 

Now my solution. 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
This works nicely on a couple of machines here. The partitions
are type 0xFD (raid autodetect).
Hope that helps.
Warm regards,
-Dimitri
