Hello, I am using SLES9 for PPC on JS20 blade server. Running autoyast with LVM on already installed client I am getting following error: "LVM Error lvremove -f -A n /dev/system/homelv /dev/hda1: open failed: No such device or address" If I reboot the machine and run autoyast installation again without any changes anything works ok and no errors occur. So I always need to start installation twice if the client already had LVM. I do not really understand the error message above, /dev/hda1 is a prepboot partition on the pseries client and is not used for LVM. I guess, there is a way to avoid starting installation twice in order to get it running. Any help would be highly appreciated... Here is my partitioning section in the autoyast.xml file: <partitioning config:type="list"> <drive> <device>/dev/hda</device> <initialize config:type="boolean">true</initialize> <partitions config:type="list"> <partition> <crypt_fs config:type="boolean">false</crypt_fs> <crypt_key></crypt_key> <partition_nr config:type="integer">1</partition_nr> <partition_type>primary</partition_type> <format config:type="boolean">false</format> <loop_fs config:type="boolean">false</loop_fs> <mount></mount> <partition_id config:type="integer">65</partition_id> <size>16M</size> </partition> <partition> <crypt_fs config:type="boolean">false</crypt_fs> <crypt_key></crypt_key> <partition_nr config:type="integer">2</partition_nr> <partition_type>primary</partition_type> <filesystem config:type="symbol">ext3</filesystem> <format config:type="boolean">true</format> <fstopt>noatime,acl</fstopt> <label></label> <loop_fs config:type="boolean">false</loop_fs> <mount>/</mount> <mountby config:type="symbol">device</mountby> <noauto config:type="boolean">false</noauto> <partition_id config:type="integer">131</partition_id> <size>2000M</size> </partition> <partition> <lvm_group>system</lvm_group> <crypt_fs config:type="boolean">false</crypt_fs> <crypt_key></crypt_key> <partition_nr config:type="integer">3</partition_nr> <partition_type>primary</partition_type> <format config:type="boolean">false</format> <loop_fs config:type="boolean">false</loop_fs> <mount></mount> <partition_id config:type="integer">142</partition_id> <partition_type>primary</partition_type> <size>max</size> </partition> </partitions> <use>all</use> </drive> <drive> <use>all</use> <device>/dev/system</device> <is_lvm_vg config:type="boolean">true</is_lvm_vg> <partitions config:type="list"> <partition> <filesystem config:type="symbol">ext3</filesystem> <lv_name>usrlv</lv_name> <mount>/usr</mount> <size>1200mb</size> </partition> <partition> <filesystem config:type="symbol">ext3</filesystem> <lv_name>varlv</lv_name> <mount>/var</mount> <size>400mb</size> </partition> <partition> <filesystem config:type="symbol">ext3</filesystem> <lv_name>homelv</lv_name> <mount>/home</mount> <size>1000mb</size> </partition> </partitions> <pesize>4M</pesize> </drive> </partitioning> Mit freundlichen Gruessen / Best regards, Tomas Baublys IBM Certified Advanced Technical Expert (CATE) pSeries and AIX pSeries Technical Sales Support JS20 Technical Focus Group Systems Sales, Central Region IBM Germany, Godesberger Allee 115, 53175 Bonn
