[Xen-users] GFS into the kernel.

[Andy Davidson <andy@xxxxxxxxxxxx>]

Hi, folks --

I'm in a terrible pickle trying to build support for gfs into the xen 
kernel.  I thought it would be reasonably straight forward, so I went 
through the following procedure :
 - grabbed Linux 2.6.12 from kernel.org.

 - patched in the -mm2 set for this version (gfs needs the dlm feature 
in this patchset.)
 - patched in the gfs stuff from http://redhat.com/~teigland/gfs2

 - used "xen-2.0-testing/linux-2.6-xen-sparse/mkbuildtree" to xenify my 
working copy of this kernel.
 - grabbed the /boot/config-2.6.11.10-xen0 file from my Xen host. 
Dropped it into the right place to use as a reference point for my new 
kernel.
 - edited arch/xen/Kconfig.drivers and added a    source 
"drivers/dlm/Kconfig"   line underneath the 'menu' line towards the top 
of the file
 - ran  ARCH=xen make menuconfig  and enabled DLM and GFS support. 
Sanity checked the rest of the config (e.g. ensured that my network hw 
was still listed as supported).
 - ran 'make-kpkg --append-to-version=xen0 --revision=ad1 --arch=xen 
kernel_image'


This failed spectacularly (but blissfully, quickly - doesn't seem to be 
debian tools related, as this also happened when I tried a simple 'make 
all').  The details of the fail are below.  Please would someone be 
willing to look at my sources or .config to point me in the direction of 
how this could be happening ?
Ideally, I would prefer to build a .deb package of the kernel with 
make-kpkg.
