Not really enough I'm afraid. We'd need a crm_report archive which has
the logs and other data necessary to debug an issue of this kind.

No.

Not really, although I have been thinking about how to mask it in the PE.
Basically if there is a fencing device active on nodeX that is about
to be fenced, under some conditions we start it on nodeY before
stopping it on nodeX.
This is cheating a little, but is the only way to make progress if
nodeY needs it to fence nodeX or another node that failed at the same
time.
