I try to configure LV's on a softwareraid (md) of two ata-disks in autoyast. On installation apears an error, 'md device is not known'. I think my configuration is right. If I try it on a running system in yast it works.

<partitioning config:type="list">

I don't think <raid_type> is needed/allowed here. <partition_id> and <raid_name> are sufficient to make this partion a raid partition which belongs to /dev/md0. I use the following:

<partition> <crypt_fs config:type="boolean">false</crypt_fs> <crypt_key></crypt_key> <format config:type="boolean">false</format> <raid_name>/dev/md0</raid_name> <partition_id config:type="integer">253</partition_id> <partition_nr config:type="integer">2</partition_nr> <size>max</size> </partition>

        <partition_type>primary</partition_type>

        <raid_name>/dev/md1</raid_name>
        <raid_type>raid</raid_type>

See above.

<partition_id> is not needed/allowed here. <partition_nr> is enough. This is not a physical partition but a kind of virtual partion. I use the following:

<partition> <raid_options> <parity_algorithm>left-asymmetric</parity_algorithm> <chunk_size>4</chunk_size> <raid_type>raid1</raid_type> </raid_options> <mount>/boot</mount> <format config:type="boolean">true</format> <filesystem config:type="symbol">ext3</filesystem> <partition_nr config:type="integer">1</partition_nr> </partition>

        <partition_nr config:type="integer">0</partition_nr>
        <raid_options>
          <chunk_size>4</chunk_size>
          <parity_algorithm>left-asymmetric</parity_algorithm>
          <raid_type>raid1</raid_type>
        </raid_options>
      </partition>

        <format config:type="boolean">true</format>
        <mount>/</mount>
        <partition_id config:type="integer">130</partition_id>

See above.

        <partition_nr config:type="integer">1</partition_nr>
        <raid_options>
          <chunk_size>4</chunk_size>
          <parity_algorithm>left-asymmetric</parity_algorithm>
          <raid_type>raid1</raid_type>
        </raid_options>
      </partition>
      <partition>
        <format config:type="boolean">false</format>
        <partition_nr config:type="integer">2</partition_nr>
        <raid_options>
          <chunk_size>4</chunk_size>
          <parity_algorithm>left-asymmetric</parity_algorithm>
          <raid_type>raid1</raid_type>
        </raid_options>

This is an md partition which is an LVM physical volume, right? You need an <lvm_group> here. Something like

<partition> <raid_options> <parity_algorithm>left-asymmetric</parity_algorithm> <chunk_size>4</chunk_size> <raid_type>raid1</raid_type> </raid_options> <lvm_group>system</lvm_group> <mount /> <format config:type="boolean">false</format> <partition_nr config:type="integer">2</partition_nr> </partition>

      </partition>
    </partitions>
    <use>all</use>
  </drive>
  <drive>
    <device>/dev/md2</device>

You already have define the device /dev/md2 by defining a partition with partition_nr 2 inside of device /dev/md above. This <drive> section can be removed.

    <partitions config:type="list">
      <partition>
        <lvm_group>system</lvm_group>
        <partition_type>primary</partition_type>
        <size>max</size>
      </partition>
    </partitions>
    <use>all</use>
  </drive>
  <drive>
    <device>/dev/system</device>
    <is_lvm_vg config:type="boolean">true</is_lvm_vg>
    <partitions config:type="list">
      <partition>
        <filesystem config:type="symbol">reiser</filesystem>
        <lv_name>user_lv</lv_name>
        <mount>/usr</mount>
        <size>500mb</size>
      </partition>
    </partitions>
    <pesize>4M</pesize>
    <use>all</use>
  </drive>
</partitioning>
