** Description changed: + Impact: d-i installations onto fake RAID (a.k.a. DM-RAID or SATA RAID) install to /dev/sda rather than to the RAID device. This may work for a while but leaves the boot arrangements vulnerable to RAID elements going away, different device ordering, etc. + Development branch (and maverick): http://bazaar.launchpad.net/~ubuntu-core-dev/grub-installer/ubuntu/revision/869 + Patch: See above; the same patch applies with only an offset. + TEST CASE: Install on a system with DM-RAID using d-i (alternate CD, server CD, or netboot). (Until new CDs are respun, testing the fixed version will only be possible using netboot, and will require 'apt-setup/proposed=true' on the installer kernel command line.) Either watch the GRUB installation step closely, or check the output of 'sudo debconf-show grub-pc | grep install_devices:' after installation (you may need to run the value through 'readlink -f' to resolve symlinks); GRUB should be installed to /dev/mapper/something rather than to /dev/sda or similar. + Regression potential: The variable controlling this code is only set for the DM-RAID and multipath cases, both of which need the same treatment, so assuming it works at all I don't expect anything else to get worse. + + Original report follows: + Binary package hint: grub-installer It was suggested in bug 568050 that I file a new bug for the grub- installer portion of installing onto fake raid. That bug has resolved the partman issues around installing onto fakeraid, so now getting grub- installer to install onto the raid device is the only remaining part to getting it working I think. Attached is a syslog from an install onto fakeraid. The system is installed and could boot off of /dev/mapper/isw_bjffiahcab_Volume0 but grub-installer still chose to install to /dev/sda and strangely reported memory leaks. This seems to be a long standing issue, and is likely a duplicate bug, but I was unable to find exactly the right bug. grub-installer doesn't have any other bugs currently open.
