[Linux-cluster] What's the proper way to shut down my cluster?

If this is RHEL5, then "#service cman stop" will attempt to shutdown all
associated daemons (fenced, for instance). Maybe it's just me, but I
find it quite unreliable...

IMHO, the best options are:

1) Use the "leave cluster" functionality from luci
2) Do it manually, something like:
   - umount gfs
   - # service clvmd stop
   - # service rgmanager stop
   - # fence_tool leave ...
   - # cman_tool leave remove ...
