Public bug reported:
Hi
My system has a boot disk, simple no raid and data disks with LVM and
RAID.
During the install, the grub-probe segfault, leading to a non bootable
system.
I did remove the data disk, and the install complet without any problem.
After reinstalling the Data Disks (LVM + SoftRaid), the update of the
Kernel was imposible, the postconfig failed during the grub-update
process.
My device config :
Boot disks : Single Device, no raid /dev/sda1
Data Disks : 6 devices, soft Raid on the device, LVM using the soft raid
device.
