The first line is the consequence of the 2nd.
And the 1st says that node2 just has seen some fencing-resource
positively reporting to have fenced himself - which
is why crmd is exiting in a way that it is not respawned
by pacemakerd.
For the reason I can just guess ...
Maybe your script is not checking whom it should actually
fence and assumes something!?
You can configure for which targets a certain fencing-resource
using pcmk_host_map, pcmk_host_check & pcmk_host_list.
Like this it would be possible that the fencing-resource was
configured differently when your script worked in a different
setup.
