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.
