Testing Netinst AMD64 CD fails to create MD devices for RAID1
 

There seems to be a bug with software RAID1 in the 06/21/2011 version
of the Testing Netinst AMD64 CD image. Separate partitions can be
linked to create the md devices, but then one or the other of the two
md devices fails after the initial sync is attempted. So the failure
is occurring before the resulting raid partitions are used. They fail
without being formated, labeled, etc. It is not possible to proceed
with the rest of the Debian installation.

I uploaded installation log copies with the following bug reports on
http://bugs.debian.org:

Bug#631331 installation-report
Bug#631338 installation-report

The hardware composition of the failing target machine is as follows:

Motherboard
ASUS P6X58D Premium
P6X58D Premium Socket 1366 X58 ATX Intel Motherboard

Intel Core i7-950 3.06 GHz

Corsair Dominator 6GB DDR3-1600

Western Digital Black Caviar ATA WDC WD1002FAEX-0

Anyone have a good work around?

Thanks,

Marc

How about making the raid before installing Debian?

Or maybe trying with another netinst image? This one is from 2011-06-25:

http://cdimage.debian.org/cdimage/daily-builds/wheezy_d-i/current/amd64/iso-cd/

And this one uses sid's installer:

Camaleon,

Thanks for the pointer to the image with the sid installer above. That
basically worked. I found a couple of issues, I think, which might
be useful to change on the installer. One is that the md devices took
a long time to sync as each was DELAYED. Installing an internal
bitmap on each device sped up the sync process and allowed the devices
to be usable:

# mdadm -G /dev/md1 --bitmap=internal

After each md device synced, I installed the internal bitmap and that
might have helped to stabilize the devices. From there I was able to
format the md devices with xfs.

A second issue is that the /etc/lilo.conf file did not specify the
initrd image which was put in the /boot directory by the Debian
installer. Once that configuration line was added to lilo.conf, the
boot loader installed and worked, the only other issue was to be sure
that the md device selected for the lilo install had to be version
0.90 as opposed to version 1.2.

Hope that helps someone and thanks for the suggestion of using the
image with the sid installer.

Marc
