I have already done extensive research about redhat 9 kernel and lvs
1. althought pre RH 9 redhat kernels did include ipvs, rh 9 doesn't. rh9 is
desktop oriented, they want us to purchase RHAS to have ipvs
2. rh 9 is heavily patched, the most intruding patches are o1 scheduler, and
the ntpl patches. these interfere with a lot of kernel work, ipvs and uml
are these i met problem with in the last week.
3. you should not use the kernel-source rpm to build your own kernel, you
should get the kernel.srpm, install it into /usr/src/redhat, and modify the
spec file to include the ipvs patch. i was able to do that, but adding the
ipvs patch, and removing O1 (which includes some preemt pieces) and ntpl
related patches from the spec file (i also removed the lowlat patches,
although they don't collide with ipvs). these redhat's optimisations are
good for desktops, but they are affecting lvs director performance as much
as 25 percent - see the list archives.
4. i will post my spec file, and the prebuilt RH 9 kernel rpms and srpms for
the i686 platform later, in the standard place.
http://mail.incredimail.com/howto/lvs/install
i will also see if the modules compile standalone with the regular redhat 9
kernel - they did compile with the 7.3 kernel.
Note. althought i don't see any impact of removing the ntpl patches from the
kernel on any functionality or stability of the machines i use, if anyone
has some input on this, i would be happy to hear it, since glibc is compiled
with ntpl support on rh 9, and i am not going to recompile that !
thank you.
Alex.
P.S. RH 7.3 is still me faviourite distro for servers, too bad it has only 8
more months of support ...

In fact my kernel-source base was a 2.4.20-8 which one delivered with Red
Hat 9.0.
Then certainly red hat has applied some patch ...
I tried from a 2.4.20 (tarball from kernel.org)
and during make modules I obtain another error :

But infortunately I don't think there is a link with ipvs code...

Have you applied any other patch to the kernel 2.4.20 source? If you
applied, you need to adapt the ip_vs_sync.c on signal setting too.
