Public bug reported:
Binary package hint: grub2
This occurs on a machine which previously worked just fine. grub-pc is
installed in the MBR of /dev/sda, which consists of a single partition
with an LVM pv on there. /boot is on /, which is on the Ubuntu-Root lv.
This worked fine.
I installed a second SATA disc, created a single partition, and added it
to the Primary-Storage vg. Now, grub-probe segfaults when called with
--target=abstraction, and the system fails to boot.
Tracing things back with gdb, this occurs because probe_raid_level on
grub-probe.c:167 is called with list->disk, which is NULL. list->disk
is NULL because grub_lvm_scan_device sets up the list of pvs associated
with each vg, but only sets pv->disk for the device grub_lvm_scan_device
was called on. Since I did not have /dev/sdb in /boot/grub/device.map,
grub_lvm_scan_device is not called with the device containing this pv.
Upon adding an entry for /dev/sdb to /boot/grub/device.map grub-probe
works, and grub boots the machine succesfully.
