Summary: mdadm: error opening /dev/mdX during during the
shutdown process
Classification: openSUSE
Product: openSUSE 12.1
Version: Final
Platform: Other
OS/Version: Other
Status: NEW
Severity: Major
Priority: P5 - None

When I have been solving #743717 I switched back to System V instead of systemd
and found that when rebooting/halting there is a following error message:

mdadm: error opening /dev/md/2

(it is / partition)

/etc/mdadm.conf file was:
DEVICE containers partitions
ARRAY /dev/md/1 UUID=7d6b05f2:c4ca4c78:aac6bf1b:9da6b8ef
ARRAY /dev/md/2 UUID=003589a4:9aa5e883:41cb207e:8a8c8541
ARRAY /dev/md/3 UUID=b9a9b25d:215c7531:0916e080:b9e2b338

openSUSE should use /dev/mdX devices in this file (otherwise disaster with
systemd may happen - I created separate bug and fix for this) but the problem
is that even with current setup /dev/md/2 file is missing when shutdown is
started (this file should be created by udev). If /etc/mdadm.conf is changed to
use /dev/mdX naming convention then there is an error "can not get exclusive
lock". I know System V is probably not priority but this problem exists there.

Reproducible: Always

Steps to Reproduce:
1. Install openSUSE with / partition on md device
2. Switch to System V
3. Reboot/Halt system
