Your xml file made me see where I had my mistake! Thanks so much. The problem I had was in the definition of the md partitions, I specified a raid_type of raid1. When defining the md partitions, you specified a raid_type of raid. The raid1 in this section was what was causing mine to error on the actual partition creation. Thanks for the help!!!! Below was my error code... <partition> <format config:type="boolean">false</format> <partition_id config:type="integer">253</partition_id> <raid_name>/dev/md0</raid_name> <raid_type>raid1</raid_type> <size>512M</size> </partition> It should have been: <partition> <format config:type="boolean">false</format> <partition_id config:type="integer">253</partition_id> <raid_name>/dev/md0</raid_name> <raid_type>raid</raid_type> <size>512M</size> </partition> -- Reynold De Marco Scientific Computing Services
