I recently detected that checkquorum script for self fencing.
That seems to work reliable, but the remaining nodes (with quorum) does not
get any fence acknowledge.
I wonder if it would be possible to extend the checkquorum script so that it
runs fence_ack_manual on the fence master after some safety timeout?
Or do you think that is a bad idea?

We are already working on a similar feature based on checkquorum, but I
got injured on my hand and I had to delay a bit the write up for the
feature (I am incredibly slow writing with one hand, never mind the
typos ;)).
The way you suggest is dangerous, so no, don't take that route.
The full feature proposal will come soon after this December
holiday/xmas break.

OK, many thanks for that info - will wait for that proposal.

Hi Fabio,
was there any progress on that topic?

As a matter of fact, yes, we are completing the first implementation and
writing down the docs and howto's.
I think the first cut will be available for testing within a week, maybe
two.

Wow, that would be great - I will test as soon as it is available.
