This means corosync.conf is probably ignored.

</i>
Yes it looks so.
><i>
</i>><i> Any guidance at all would be greatly appreciated!
</i>
Can you please attach your config file? Is corosync from ubuntu package
or your own compiled one? can you please try to stop corosync service,
login as root, add "to_stderr: yes" into logging section of config file,
execute "corosync -f" and paste result?

Honza

<p>Apologies, but it looks like my membership to the mailing list hasn't succeeded so I'm trying to manually reply by copying the message content from the archives - I hope it works!</p>

<p>The current Corosync version I'm using is <span style="font-size: 12pt;">'2.3.5' and it's the Ubuntu package. I've just rebuilt both these VMs (Ubuntu 16.04 again) and I'm getting the same issue. I've also tried compiling the latest version but I'm getting
held up on the nss requirements. </span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">What do you mean about the 'name'? I saw this on examples online, and my nodes are called `SWARM01` and `SWARM02`.</span></p>
<p><span style="font-size: 12pt;"><br>
</span></p>
<p><span style="font-size: 12pt;">Nothing at all seems to work after the first corosync run, it's really odd. I've tried `corosync -f` while running as root and `to_stderr: yes` in the config shows nothing. If I `apt remove --purge` it, I might get another
run out of it again, but it's baffling me why it only fires the first time, even if it is ignoring the config. I've tried removing the interface segment and running `corosync -t` after every change which shows no output.</span></p>
