[Bug 752694] Re: Grub2 installs on the wrong device if in a RAID config

[Ameet Paranjape]

@Colin,  you are correct the installer is behaving correctly now.

I cannot get this system to reproduce the error on Ubuntu server 11.04
anymore.  I swore I saw it the first time I put Ubuntu on this box...

Anyway, I need to do some investigation on my side about when and why
this occurs.  i.e. installing on an existing RAID config or a new one,
RAID 0 vs 1,5,10, installing Ubuntu over another OS, etc.  I will update
the bug when I have more data.

Title:
  Grub2 installs on the wrong device if in a RAID config

Status in “grub2” package in Ubuntu:
  Confirmed

Bug description:
  Binary package hint: grub2

  - Install Ubuntu server 11.04 Beta1 x86_64 on a HP DL380 G7 with a RAID controller using a USB startup disk
  - The OS install proceeds normally, but at the end of the install when it is time for GRUB2 to load itself onto a local disk, the installer is incorrectly selecting the USB startup disk's /dev location instead of a /dev on the box
  - If the USB stick is removed for reboot after the install completes, the system does not boot to a login

  Workaround:
  - Plug the USB stick back into the system
  - Reboot the box
  - Manually move grub2 off the usb stick on to a local drive using 'sudo grub-install /dev/sda' or whatever your local disk's location is

  This was an issue in 11.04 Alpha2, it went away in 11.04 Alpha3, but
  has returned in 11.04 Beta1 on the same box and same hardware.
