Execution of a flow before NR shutdown? I thought I saw a forum thread on this? But I can't seem to find it, so maybe this is not possible currently?

Since I am running a primary and secondary NR setup, not a cluster, no transparent fail-over type of thing. Just stop and start of services as applicable.

It would be nice to implement the graceful fail-over and recovery logic in NR as much as possible. But could just do it external to NR, since the non-graceful control will be external to NR anyway.

There was [this topic](https://discourse.nodered.org/t/node-redundancy/10762) about redundancy.  
Is that what you was looking for?

It is part of ongoing work that the node.done calls are part of. See [Use of msg, send, done in node that can also be triggered by button & more than one input msg to one logical process, when to call done?](https://discourse.nodered.org/t/use-of-msg-send-done-in-node-that-can-also-be-triggered-by-button-more-than-one-input-msg-to-one-logical-process-when-to-call-done/28934/11)

@dceejay  
Yup, that was it, I recall the discussion about how done() support is not complete across everything as yet.
