DRBD Kernel Modules - how to compile?

[FordPrefect]

Hi,

I got Archlinux installed on some Pogoplugs (http://archlinuxarm.org/platforms/armv5 ... g-series-4)

Until now, nearly everything I wanted worked out of the box, simply by installing the necessary software via pacman.

Now I try to set up a drbd device on two pogoplugs, on each pogo runs a 3.1 Kernel

$this->bbcode_second_pass_code('', 'Linux pogoplug02 3.1.10-13-ARCH #1 PREEMPT Mon Aug 20 15:46:18 UTC 2012 armv5tel GNU/Linux')

After installing (??) the drbd userland tools, I find in /usr/src the following:

$this->bbcode_second_pass_code('', '
/usr/src/linux-3.1.10-13-ARCH/drivers/block/drbd
/usr/src/linux-3.1.10-13-ARCH/drivers/block/drbd/Kconfig
/usr/src/linux-3.1.10-13-ARCH/include/linux/drbd_nl.h
/usr/src/linux-3.1.10-13-ARCH/include/linux/drbd.h
/usr/src/linux-3.1.10-13-ARCH/include/linux/drbd_limits.h
/usr/src/linux-3.1.10-13-ARCH/include/linux/drbd_tag_magic.h
')

But no precompiled kernel Module.

Do I need to set up a complete toolchain in my pc to recompile the kernel, or is there a "simpler way" to get a running drbd.ko Kernel module?

Normaly, on my other servers and desktops I use Debian, so I know how to make a Kernel Debian Package and install it on my systems.
I have no idea how to do that with the help of pacman - or should I recompile the whole kernel as it was done 15 years ago?

Thanks a lot for your help!

Cheers,

Is it CONFIG_BLK_DEV_DRBD
How old is your plug initial install? If recent install linux-kirkwood

Hi,

I think it's the initial Install is from September 2012. Is it simpler to re-install the latest version instead of
upgrading either the kernel itself or the whole system? (I ran in a dead end once, trying to make a "full"
distribution upgrade with pacman)

BTW: No, originally it's not enabled.
$this->bbcode_second_pass_code('', '[root@pogoplug02 linux-3.1.10-13-ARCH]# zcat /proc/config.gz | grep -i DRBD
# DRBD disabled because PROC_FS, INET or CONNECTOR not selected
[root@pogoplug02 linux-3.1.10-13-ARCH]#
')

Cheers,

After updating to linux-kirkwood (my uboot was new enough it seems - i ran into another problem when
trying to state the r0 drdb device up and running.....:

Seems not too good.
