[Bug 1354948] Re: Installed Ubuntu 14.04.1 Desktop LTS using RAID1+LVM and Grub failed to install

[Alex Karasulu]

I have almost the exact same problem. The same memory error messages.
Using LVM + RAID with thin-pools and my root partition is on a thin
volume. There are serious problems here with grub bugs I think seeing
from similar posts on google. Here's some of the same output you got
previously:

 Internal error: Unreleased memory pool(s) found.
You have a memory leak (not released memory pool):
 [0xc47990] dtree
 [0xc41e90] dtree
Internal error: Unreleased memory pool(s) found.

Title:
  Installed Ubuntu 14.04.1 Desktop LTS using RAID1+LVM and Grub failed
  to install

Status in “grub-installer” package in Ubuntu:

Bug description:
  I booted on Ubuntu 14.04.1 Desktop 64 bit (using the USB), went to ry
  Ubuntu and partition the 2 HDD (SATA 320GB) as I wanted, which is:

    - 2x 512MB as RAID1 (md) w/ ext4 for /boot
    - 2x 6GB as RAID0 (md) for swap
    - 2x 64GB as RAID1 (md) + 1 Logical Volume (LVM2) using all available space with ext4 as /
    - 2x remainder space as BTRFS RAID1 configuration for /home

  Why so complex? I had first only the /boot and swap on software RAID, the rest was under BTRFS with 2 volumes (for home and for /), but it was problematic to boot. So I "moved" the / to another more classical partition scheme using mdadm and lvm.
  But it does not work.

  I did this to at least get grub-install to report no blocking error:
  sudo -s
  echo raid1 >> /target/etc/modules
  echo dm-mod >> /target/etc/modules
  echo dm-snapshot >> /target/etc/modules
  echo dm-mirror >> /target/etc/modules
  echo raid1 >> /target/etc/initramfs-tools/modules
  echo dm-mod >> /target/etc/initramfs-tools/modules
  echo dm-snapshot >> /target/etc/initramfs-tools/modules
  echo dm-mirror >> /target/etc/initramfs-tools/modules
  mount --bind /dev /target/dev
  mount --bind /dev/pts /target/dev/pts
  mount --bind /proc /target/proc
  mount --bind /sys /target/sys
  chroot /target grub-install /dev/sda
  chroot /target grub-install /dev/sdb

  The command grub-install is outputing in both cases this:
  Installing for i386-pc platform.
  You have a memory leak (not released memory pool):
   [0x1b765f0] dtree
  Internal error: Unreleased memory pool(s) found.
  You have a memory leak (not released memory pool):
   [0x1b774f0] dtree
  Internal error: Unreleased memory pool(s) found.
  You have a memory leak (not released memory pool):
   [0x1b79a70] dtree
  Internal error: Unreleased memory pool(s) found.
  Installation finished. No error reported.

  
  I will report after reboot if it worked or not.
