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.
