I have a hardware RAID 1 which seems to be recognized find by the Ubuntu installer. I choose the "Entire Disk - Guided" partition strategy and accept the defaults, writing them to disk. When it comes to choosing where to put Grub2, however, everything I try fails. Any advice would be awesome.

Drop to shell and extend your question with errors from the ``/var/log/syslog``. – Roman Byshko Jul 31 '12 at 11:15

Does your server happen to have something like a FC (Fibre Channel) card installed so your server sees some additional LUNs / drives there? If that's the case, Debian/Ubuntu installer can sometimes get confused and try to install GRUB to those SAN drives instead of the drives you originally planned... – Janne Pikkarainen Jul 31 '12 at 11:28

No, it has 2 x 160gb and 2 x 320gb. Each pair is in a hardware RAID 1. I am trying to install on the 160gb pair, leaving the 320gb pair to format and mount after installation. – MFB Jul 31 '12 at 11:40

In Debian, there is Expert Install, there you can drop to shell. This might be in Ubuntu too. – Roman Byshko Jul 31 '12 at 12:30

I'm trying to do a similar thing with RAID 0. I haven't been successful yet, but I believe you'll have to install grub2 manually. I managed to get my Ubuntu installation to "succeed" by following steps here: https://wiki.archlinux.org/index.php/GRUB2, but I can't boot... – LukeGT Aug 17 '12 at 01:47

@LukeGT Thanks for posting. Let me know how you go. I ran out of time so I'm now running something fairly critical on a single disk :( I would love to get it on the RAID if possible. Cheers – MFB Aug 17 '12 at 01:55
