[Bug 577369] Re: "Grub loading." raid1 rootfs takes very long

[Phillip Susi]

Is this still happening?  Can you try to rename your grub.cfg and see if
you quickly get to the grub rescue shell?  Then manually source the
renamed cfg and see if the delay is there?  You might also try set
debug=all first for much more verbose output.

Title:
  "Grub loading." raid1 rootfs takes very long

Status in “grub2” package in Ubuntu:
  Incomplete

Bug description:
  Binary package hint: grub2

  The "Grub loading." message only shows if the shift key was held down,
  otherwise only a blank screen with a blinking cursor is shown.

  It takes over 60 seconds before boot continues / menu is shown.

  /boot is on raid1 (md0)
  and the root fs is a logical volume on another raid1 (possibly not available and the reason for the delay?)

  
  From the grub.cfg:

  ### BEGIN /etc/grub.d/00_header ###
  if [ -s $prefix/grubenv ]; then
    load_env
  fi
  set default="0"
  if [ ${prev_saved_entry} ]; then
    set saved_entry=${prev_saved_entry}
    save_env saved_entry
    set prev_saved_entry=
    save_env prev_saved_entry
    set boot_once=true
  fi

  function savedefault {
    if [ -z ${boot_once} ]; then
      saved_entry=${chosen}
      save_env saved_entry
    fi
  }

  function recordfail {
    set recordfail=1
    if [ -n ${have_grubenv} ]; then if [ -z ${boot_once} ]; then save_env recordfail; fi; fi
  }
  insmod raid
  insmod mdraid
  insmod lvm
  insmod ext2

    insmod gfxterm

    if terminal_output gfxterm ; then true ; else
      # For backward compatibility with versions of terminal.mod that don't
      # understand terminal_output
      terminal gfxterm
    fi
  fi
