Package: grub-pc Version: 1.99-27 Severity: important Tags: upstream As far as I can tell, GRUB-2 doesn't support any kind of symlinks to /dev/sd*, such as /dev/disk/by-path/*
Specifically, consider the following setup: * GRUB Root: /boot/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 (AKA: /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000000000000-lun-0-part1) * Boot partition: /boot (AKA: /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000000000000-lun-0-part2) * Symlinks: /boot/pci-0000:07:00.0-sas-0x1221000003000000-lun-0/boot => . /boot/pci-0000:07:00.0-sas-0x1221000003000000-lun-0/grub => . * Device mapping ($GRUB_ROOT/device.map): (hd0) /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000000000000-lun-0 (hd1) /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000001000000-lun-0 (hd2) /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000002000000-lun-0 (hd3) /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 * Auto-generated GRUB-2 config file ($GRUB_ROOT/grub.cfg), whose actual contents are irrelevant, but which loads GRUB modules from the first partition and kernels/initrds from the second partition. * Valid device symlinks from udev: /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 => ../../sde /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0-part1 => ../../sde1 /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0-part2 => ../../sde2 /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0-part3 => ../../sde3 /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0-part4 => ../../sde4 Now, with that set up, I run: grub-install --no-floppy \ --root-directory=/boot/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 \ /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 And it dies with an error: /usr/sbin/grub-probe: error: cannot find a GRUB drive for /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0. Check your device.map. If I edit the device.map file and replace it with "/dev/sde" (which it is a symlink to, by the way), then run: grub-install --no-floppy \ --root-directory=/boot/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 \ /dev/disk/by-path/pci-0000:07:00.0-sas-0x1221000003000000-lun-0 /dev/sde Then it works flawlessly. Unfortunately, this is not useful because those device names change on boot, depending on whether or not I have USB devices attached to the system. Even worse, with my configs: grub-probe -m /boot/pci-0000\:07\:00.0-sas-0x1221000003000000-lun-0 \ -t drive '(hd3)' Segmentation fault Cheers, Kyle Moffett -- To UNSUBSCRIBE, email to debian-bugs-dist-requ...@lists.debian.org with a subject of "unsubscribe".
