PAF will output debug messages if debug is enabled on Pacemaker side (in /etc/sysconfig/pacemaker or /etc/default/pacemaker). It is true "debug-<action>" commands are not supported with PAF because they are focused on non-promotable agents[1]. PAF rely on cluster contexts and notify actions to make various checks, recovery and node election, which are not set or triggered when using "debug-<action>" commands. But this can be emulated I suppose, eg. by setting the `target-role` by hand and leave the cluster do its magic transitions? > Only negative is that the documentation for promotional pgsql cluster > is dated, Well, PAF documentation is dated as well, they both deserve some documentation updates from the authors (erm… I swear I'll do). [1] as far as I remember, I'm interested to know if this not true anymore. _______________________________________________ Manage your subscription: https://lists.clusterlabs.org/mailman/listinfo/users ClusterLabs home: https://www.clusterlabs.org/
