And here we go again. It was about time to update my server to the latest Ubuntu. Everything seemed fine and the installation went its usual way. Beforehand I made sure that I new what partition will be what and what data on what partition is worth keeping.
The partitioning tool in manual mode did what it should do, the packages installed and then came the famous question if you want to install GRUB in the MBR. Of course I selected “yes” and all I got was an error.
Switching to the fourth console (I chose the server ISO) revealed the culprit. Obviously the size of the core.img increased again. Here an excerpt of the error message:
/usr/sbin/grub-bios-setup: warning: your core.img is unusally large. It won't fit in the empedding area. /usr/sbin/grub-bios-setup: error: embedding is not possible, but this is required for RIAD and LVM install.
This turned out to be a little problem. The RAID partitions start too early for the new GRUB 2.00 but I have some data on this RAID that I need to keep.
Luckily I had another RAID device with enough space so that I could backup all my data. And now I can start the installation again, but this time I have to wipe the the LVM and the RAID on the boot drives.
