Comment 170 for bug 1274320

Further to yesterday's comment, issue is occuring while installing (using debian-installer), at the "Install the GRUB boot loader on a hard disk" stage. Displayed error is: "Unable to install GRUB in /dev/mapper/<machine_name>--vg-root"

I have worked-around by choosing not to use LVM (I am choosing the "Guided - use entire disk" option), which reduces disk manageability. I'm left with the impression installing Ubuntu on enterprise-grade hardware is a bit alpha.
