Finally found the solution, which leaves me with a question. Having successfully installed an 11.10 server with RAID, I tried again on 11.10 desktop: this time, after getting the message that GRUB had not installed, I chrooted into /target/, did 'sudo-apt-get install mdadm', then 'sudo grub-install /dev/sda'. No errors.
So the Ubuntu graphical installer (Ubiquity? or whatever underlying package is responsible) is not installing mdadm into the target installation, and consequently GRUB can't be installed. Which package should this bug be filed against? -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/880766 Title: ubiquity and grub-install: fails to install grub on software RAID To manage notifications about this bug go to: https://bugs.launchpad.net/grub/+bug/880766/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
