Any idea which distro you saw supported this? Upstream grub explicitly does not support diskfilter writes (in other words, writing directly to /dev/md* devices, LVM, etc), but rather expects one to write to the underlying device, because there are just too many different cases in which writing directly to the top layer might break things.
My workaround (I'm still testing) would be to have grub-installer pick the underlying devices to install to. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1487365 Title: Ubuntu14.04 .3 RAID installation fails on firestone To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/debian-installer/+bug/1487365/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
