Public bug reported: Binary package hint: ubiquity
I have three disks for software raid that I have set up as /dev/sd[abc]1. The third disk is slower than the first two, so I have it marked as "writemostly" through mdadm. They are assembled onto raid array /dev/md0. However, ubiquity tries to guess that the bootloader should be installed on all /dev/sd[abc]. That is fantastically-smart behaviour. However, when probing the array properties, it gets confused. Output of /var/log/messages is: Nov 24 02:52:38 ubuntu grub-installer: info: Installing grub on '/dev/sda /dev/sdb writemostly /dev/sdc' Nov 24 02:52:38 ubuntu grub-installer: info: grub-install supports --no-floppy Nov 24 02:52:38 ubuntu grub-installer: info: Running chroot /target grub-install --no-floppy --force "/dev/sda" Nov 24 02:52:40 ubuntu grub-installer: Installation finished.

Nov 24 02:52:44 ubuntu grub-installer: error: Running 'grub-install --no-floppy --force "writemostly"' failed. At this point, I get the graphical "Bootloader install failed" dialog, with "How would you like to proceed?" The problem is that the "okay" button is always greyed out, and thus the installation hangs/fails. ** Affects: ubiquity (Ubuntu) Importance: Undecided Status: New -- unity grub-install on raid incorrectly handles 'writemostly' flag https://bugs.launchpad.net/bugs/680751 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
