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. -- Tiago Sousa -- To UNSUBSCRIBE, email to [email protected] with a subject of "unsubscribe". Trouble?
