Note: "permalinks" may not be as permanent as we would like,
direct links of old sources may well be a few messages off.

recently I've built HA cluster on two computers running Mandriva Linux 
Powerpack 2009 Spring.
I used heartbeat and drbd to do this.

The first computer has 32-bit architecture, and the second has Core2 Duo 
processor, so I installed x86-64 version of Mandriva on the second computer.

There was no problems until I decided to update both systems. I used 
"urpmi --auto-update" command.
The first machine updated finely, but after I updated software on the 
x86-64 machine, drbd on this computer was broken.

Here goes some info about my installation:
[root at node1 /]# uname -a
Linux node1.akme #1 SMP Tue Nov 3 14:32:52 EST 
2009 x86_64 Intel(R) Core(TM)2 Duo CPU     E6550  @ 2.33GHz GNU/Linux

[root at node1 /]# rpm -qa "*drbd*"

[root at node1 /]# service drbd start
Starting DRBD resources: Can not load the drbd module.

[root at node1 /]# lsmod | grep drbd

I decided that there's drbd kernel module does not exist anymore

So I tried to install drbd from source guided by instructions from

After kernel module was built and installed.

For a strange reason module was installed into
/lib/modules/ folder,
not into
/lib/modules/, as expected.

Next I tried to modprobe that module:
[root at node1 /]# cd /lib/modules/
[root at node1 block]# modprobe drbd.ko
FATAL: Module drbd.ko not found.

Insmod leads to failure too:
[root at node1 block]# insmod drbd.ko
insmod: error inserting 'drbd.ko': -1 Invalid module format

Built module has following structure:
[root at node1 block]# modinfo drbd.ko

Please, advice me how to correctly install drbd kernel module, may be 
there is RPM in repository?
I suppose, those three "drbd-utils*" packages don't contain kernel 
module itself.
