Are you reinstalling over an existing system, or a totally new one ? If the former,  does your kickstart include the stanza to remove any existing partitions ?

# Partition clearing information

Subject: [cobbler] Changes in kickstart file do not take effect in Cobbler.

I am using Cobbler to install SLES 11 SP2 and it has been running fine all the while. Recently I modified the kickstart file by changing the size of the root partition from 18GB to 36GB. To my surprise the modification did not take place - Cobbler created a root partition with the size of 18GB. I tried removing the profile, renaming it, but no success.

I am completely stump as to where Cobbler is getting the value 18GB from. Is there some kind of cache that is keeping the old kickstart file somewhere and I need to clear that up first?

The part where I did the modification:

<partition>
  <create config:type="boolean">true</create>
  <crypt_fs config:type="boolean">false</crypt_fs>
  <filesystem config:type="symbol">ext3</filesystem>
  <format config:type="boolean">true</format>
  <fstopt>acl,user_xattr</fstopt>
  <loop_fs config:type="boolean">false</loop_fs>
  <lv_name>lvroot</lv_name>
  <mount>/</mount>
  <mountby config:type="symbol">device</mountby>
  <partition_id config:type="integer">131</partition_id>
  <raid_options/>
  <resize config:type="boolean">false</resize>
  <size>36GB</size>
</partition>


Any help is appreciated.

Thanks.
