part of my kickstart file is now: clearpart --all --initlabel part --ondisk=sda raid.01 --asprimary --bytes-per-inode=4096 --fstype="raid" --onpart=sda1 --size=20000 part --ondisk=sda swap --asprimary --bytes-per-inode=4096 --fstype="swap" --onpart=sda2 --size=4000 part --ondisk=sda raid.02 --asprimary --bytes-per-inode=4096 --fstype="raid" --onpart=sda3 --size=1 --grow part --ondisk=sdb raid.03 --asprimary --bytes-per-inode=4096 --fstype="raid" --onpart=sdb1 --size=20000 part --ondisk=sdb swap --asprimary --bytes-per-inode=4096 --fstype="swap" --onpart=sdb2 --size=4000 part --ondisk=sdb raid.04 --asprimary --bytes-per-inode=4096 --fstype="raid" --onpart=sdb3 --size=1 --grow raid / --bytes-per-inode=4096 --device=md0 --fstype="ext3" --level=1 raid.01 raid.03 raid /home --bytes-per-inode=4096 --device=md1 --fstype="ext3" --level=1 raid.02 raid.04 I changed the config to use --ondisk above and at install I get a message saying: "Unable to locate partition sda1 to use for ." Press OK to reboot your system. The above is the correct message. I did not leave any words out. It looks good to me. What might I have wrong? sda works just fine when not installing RAID. Jerry
