Hi guys,

I am following this guide for setting up a HA Cluster with Postgres: http://library.linode.com/linux-ha/high ... untu-10.04

I was able to set it up for Ubuntu 10.04 LTS 64Bits, but pengine kept crashing on me (because pacemaker was kind of old and buggy in this realease). So I have decided to try the 12.04 release instead.

Everything is fine except that I cannot get the drbd module to load. I have done the following then rebooted:

apt-get install -y  linux-headers-server drbd8-utils build-essential psmisc

and use vmlinuz-3.2.0-24-virtual with pv-grub-x86_64 as my kernel - here's my /boot/grub/menu.lst

timeout 10

title           Ubuntu 12.04 LTS, kernel 3.2.0-24-virtual
root            (hd0)
kernel          /boot/vmlinuz-3.2.0-24-virtual root=/dev/xvda ro quiet
initrd          /boot/initrd.img-3.2.0-24-virtual

Here's the 'uname -a':

Linux ha1-db 3.2.0-24-virtual #37-Ubuntu SMP Wed Apr 25 10:17:19 UTC 2012 x86_64 x86_64 x86_64 GNU/Linux

Unfortunately, both 'modprob drbd' and 'service drbd start' fail saying that drbd is not loaded:

root@ha1-db:~# modprobe drbd
FATAL: Module drbd not found.

root@ha1-db:~# service drbd start
 * Starting DRBD resources                                                                                                                                                                             Can not load the drbd module.

QUESTION: Has anyone had success installing drbd with the Linode builds of Ubuntu 12.04 LTS 64Bits?

Thanks a lot in advance,

Arnaud.

Looks like I had to compile my own DRBD and update drdb that way. Here's what I did following this guide (and adapting for my installed kernel): http://www.drbd.org/users-guide/s-build ... ource.html

apt-get install -y linux-headers-server drbd8-utils build-essential psmisc bison flex
apt-get install linux-headers-3.2.0-24-virtual

wget http://oss.linbit.com/drbd/8.4/drbd-8.4.1.tar.gz
tar xfvz drbd-8.4.1.tar.gz
cd drbd-8.4.1/
./configure --prefix=/usr --localstatedir=/var --sysconfdir=/etc --with-km

make KDIR=/lib/modules/3.2.0-24-virtual/build
make install

You may not need 'drbd8-utils' in there, but since I did not feel like starting from scratch and it worked that way.... this is my solution so far

Hope it helps someone on day.

Arnaud.

You don’t need to build DRDB manually. Instead, just do

apt-get install linux-image-extra-virtual

and everything will work.
