How can I stop Cardano Node correctly without running it as a service?

Question

Is there a way to correctly stop cardano-node different than making it run as a service?

I have noticed that, since version 1.34.1, I'm getting the message Validating chunk no. X out of Y. every time I restart it.

I assume this is happening because I'm not stopping it correctly.

I'm using tmux and I just use kill-session command to stop my node.

Answer 1

I'm using tmux and I just use kill-session command to stop my node.

That is probably not a safe shutdown.

For a safe shutdown you should go to the terminal where the node is running and send Control-C. You will then get a message like:

[mainnet:cardano.node.ChainDB:Info:5] [2022-05-30 05:32:03.82 UTC] Closed db with

Shutting down..

This indicts a correct and safe shutdown.

Answer 2

I think you should resume the session and press Control-C to stop cardano-node when you are running it in tmux.

Answer 3

I've seen people suggest kill -2 <PID> as it sends a SIGINT (similar to CTRL-C), but it never quite completes for me. There is always 1 external network connection active and the main node process is still running, which I then kill <PID> after 10-15 minutes.

Although doing it this way does start up more quickly and avoids most of the Validating chunk X of Y work.
