I can confirm this bug in Ubuntu 10.04 beta1 alternate cd, installing on a ATI SB600 fakeraid (raid0 formed by /dev/sda and /dev/sdb). Grub installer fails trying to install the boot loader on the first disk of the array (/dev/sda), instead of the array /dev/mapper/pdc_xxxxxxx.
>From the logs (attached syslog.gz) it seems that grub-install cannot map the boot device due to missing device.map. There are also many errors related to failed access to /proc which is not mounted inside /target. I can successfully install grub2 manually on the fakeraid array following these steps: 1) create /target/boot/device.map containing "(hd0) /dev/mapper/pdc_xxxxxxx" 2) mount /proc inside target with "mount -o bind /proc /target/proc" 3) run "chroot /target grub-install /dev/mapper/pdc_xxxxxxx" 4) run "chroot /target update-grub" Also update-grub cannot find my Windows partition, but re-running the command after booting in Lucid solves the problem. grub-installer 1.49ubuntu7 grub-pc 1.98-1ubuntu1 ** Attachment added: "syslog.gz" http://launchpadlibrarian.net/42261384/syslog.gz -- Cannot install grub2 on dmraid with text-mode installer https://bugs.launchpad.net/bugs/420992 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
