Description shrek-m 2007-10-28 21:41:39 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux x86_64; de; rv:1.8.1.8) Gecko/20071019 Fedora/2.0.0.8-1.fc7 Firefox/2.0.0.8

Description of problem:
todays fc6 update to f7.
the raid1 and raid5 devices are no longer auto detected at boot time.

`mdadm --auto-detect; mount -a` works in /etc/rc.local or as root.

Version-Release number of selected component (if applicable):
initscripts.x86_64 8.54.1-1   

How reproducible:
Always


Steps to Reproduce:
1. yum dist upgrade from fc6 to f7
2. reboot

Actual Results:
fstab errors while booting
/dev/md0 /dev/md1 /dev/md2 are no longer available

fc6 => f7 changed the devices
hda => sda  PATA
sda => sdb  SATA
sdb => sdc  SATA
sdc => sdd  SATA

Expected Results:
the raid devices should be available and mounted as in fc6 at boottime.

Additional info:
a;
the boot device (PATA) was under fc6 detected as "hda" and under fc7 as "sda"
this will evtl. produce the BMDMA, Emask errors while booting.

b;
"pci=nommconf"  kerneloption disables the MMCONF warning while booting.

Comment 3 Bill Nottingham 2007-10-29 15:35:04 UTC 
Do you have a mdadm.conf?
Comment 4 shrek-m 2007-10-29 17:41:56 UTC 
no, i guess that the mdadm.conf was here in fc6 and was somehow blown away by
the `yum update`

# mdadm --examine --scan >> /etc/mdadm.conf
# echo "MAILADDR root" >> /etc/mdadm.conf 

now it is ok.

# cat /etc/mdadm.conf 
ARRAY /dev/md0 level=raid1 num-devices=3 UUID=ca2d499b:ff364e06:7c39cde1:27429f10

but why they are not auto-detected without the conf file if this works?
tested and works without mdadm.conf
----why not additional? ----
if [ ! -f /etc/mdadm.conf ]; then
    /sbin/mdadm --auto-detect

Comment 5 Bill Nottingham 2007-10-29 18:00:01 UTC 
Historical reasons. One issue is that you probably don't want to be scanning all
drives on every boot on machines you don't need to.
Comment 6 shrek-m 2007-11-09 14:00:46 UTC 
no raid-problems with the new generated mdadm.conf, thanks.

- with a 80wire/40pin ide-cable the BMDMA errors are gone away too.
- the "ide device names change" as scsi devices is mentioned in the release-notes.
