I think I have a patch that fixes this, basically adding another step to generate the 'partitions' that include the md arrays, and to drop the md arrays themselves as being part of any array obtained from /proc/mdstat
If this is OK, can it be made available for 12.04 support? ** Patch added: "Update for os-prober to detect mdadm RAID" https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1217933/+attachment/3793028/+files/detect-mdadm.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1217933 Title: update-grub fails to detect other md OS To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub2/+bug/1217933/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
