One disk or twenty, LVM for all or just a few filesystems, it should still work. So you still have some problem in your definitions that hasn't been revealed here yet.
Since you're running into the problem during the install, there aren't a lot of files you could post here for review. But could you walk through, in detail, what you are doing during the install, from the point of formatting the DASD through to the error? What options are you selecting on which panels, and what steps you go through to define each physical volume, volume group and logical volume? Perhaps, given this information, others here can spot the problem, or test your config on their own systems and find the mis-step. If you can, take "pictures" of the major windows involved in the process. I'm not sure that the group here will allow posting them, but you could, at the very least, create a Flickr account and post them there, and then supply the URL to get to them here. -- Robert P.
