[Bug 1258111] Re: Ubuntu installer unable to install GRUB to software raid (entire disk)
You need to install the system to the raid array built on a partition, and install grub to the whole disk, since that is what the bios knows about and boots. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258111 Title: Ubuntu installer unable to install GRUB to software raid (entire disk) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1258111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs

Will take a look. Thanks.

I did use the entire underlying disk drive, as this seemed to be the way palimpsest wanted it to be done. This was my third or fourth attempt at doing the installation and I am pretty sure I had previously tried RAID-ing the partitions, so that I ended up with /dev/md0, /dev/md1, /dev/md2, etc. but grub wouldn't install there either. I then tried installing to a single drive, figuring I could attach the second disk later. After installing successfully and rebooting, I found I had a single RAID device /dev/md3 spanning the entire disk and it was rebuilding. I allowed it to finish and I ended up with a seemingly working RAID and a working grub. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258111 Title: Ubuntu installer unable to install GRUB to software raid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1258111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1258111] Re: Ubuntu installer unable to install GRUB to software raid
It has been possible in the past since they were managed by dmraid and grub had hooks to recognize that and understand that the bios recgonizes the array as a single drive. I started some discussion upstream maybe a year ago about how to proceed with the mdadm transition and being able to detect whether or not the bios handles the raid but it was never resolved.

[Bug 1258111] Re: Ubuntu installer unable to install GRUB to software raid
You built the raid array using the entire underlying disk drive so grub can not be installed on them. You must partition the drive and use a partition as the raid component. ** Changed in: grub-installer (Ubuntu) Status: New => Invalid -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1258111 Title: Ubuntu installer unable to install GRUB to software raid To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/grub-installer/+bug/1258111/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
[Bug 1258111] Re: Ubuntu installer unable to install GRUB to software raid
Ubuntu installer popped up a window with the following message: "Unable to install GRUB in /dev/sda Executing 'grub-install /dev/sda' failed. This is a fatal error." I attempted to run this command manually at this point, with the following result: $ sudo grub-install /dev/sda Path `/boot/grub' is not readable by GRUB on boot. Installation is impossible.
