I think. I already had the LVM partitions set up, but when I booted up into the install, and went to the shell, I couldn't see them (although the installer saw them). I had to do raidstart on all my md devices, and then scan by doing somethign liek vgscan and lvscan, and then the devices showed up. So I deleted them and re-added them, per your instructions, and when I printed out the config, looks like they were striping. I was then able to install on it. So I don't think the reboot step is necessary, you just need to precreate the config manually in the shell first. Thanks for your help. Russ
