[Debian-ha-maintainers] Bug#571134: redhat-cluster-suite: Soft lockup in send_dlm on shutdown

[Tiago Sousa]

I stumbled onto a similar problem. In my case I'm only using cman and
clvm, not the package redhat-cluster-suite proper, but I believe this
applies to you as well.

My problem happened because the debian reboot/shutdown runlevel scripts
are stopping first cman, then clvm. That is clearly the wrong behaviour,
and I fixed with:

mv /etc/rc0.d/S51clvm /etc/rc0.d/S04clvm
mv /etc/rc6.d/S51clvm /etc/rc6.d/S04clvm

So I suggest you take a close look at /etc/rc0.d (shutdown runlevel) and
see if things are stopping in the right order . All services that depend
on clustering (in my case it was just clvm) must be stopped before
shutting down the main cluster services (cman). If you can stop all
services manually, then it's surely a init order problem.
