I was able to install using the alternate installer. An option comes up to disable software raid, which I accepted. As a result I'm able to see all disks. Later after installation completes, I ran update-grub, and got some errors about software raids (of which I should have none, and if I do they're unintentional), and it fails to parse operating systems on other drives. I removed the "dmraid" package, and reran update-grub, and it works correctly.
This problem is somehow related to incorrectly picking up software raid volumes that aren't in use, or previously existed. A workaround is as I explained, use the alternate installer, and immediately remove the "dmraid" package. -- ubiquity partition step does not show some hard drives https://bugs.launchpad.net/bugs/459054 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
