Thanks, I'll do that. It might be a week or two. But I have solid C skills going back 25 years, and spent a decade doing C++. Let me know if there's a "getting started guide" for developers on the Samba project. Key tools to install, etc. I will need to spin up a VM to work in. Also, should chat with the CTO so he's aware.

Folks, thank you for being so helpful. I can't quite figure out the exact command line to get ctdb dbstatistics for the locking.tdb in CSV format. How do you do this?

Thanks, i added "Environment=PATH=$PATH:/usr/local/samba/bin:/bin". Needed also to add "/bin" because couldnt find "sleep". Thats the script now: ---- [Unit] Description=CTDB Documentation=man:ctdbd(1) man:ctdb(7) After=network-online.target time-sync.target ConditionFileNotEmpty=/usr/local/samba/etc/ctdb/nodes [Service]

Ah, yes, thats it Ralph.. Good one. Then in the systemd.service file you need to add.

Hai, Hmm, about .. > "Environment=PATH=$PATH:/usr/local/samba/bin:/bin". > Needed also > to add "/bin" because couldnt find "sleep". /bin should be found in $PATH.. In since it looks like it does not. Then i suggest this: Environment="PATH=$PATH:/usr/local/samba/bin:/usr/local/samba/sbin:/bin:/sbin:/usr/bin:/usr/sbin" # to make sure you
