<p class="MsoNormal">We tried to follow the Linstor documentation for setting up multiple network paths, but there seems to be a step missing.

<p class="MsoNormal">Per the DRBD 9 docs, there should be “path” entries like this…<o:p></o:p></p>

<p class="MsoNormal"><o:p> </o:p></p>
<p class="MsoNormal">What did we miss? There seems to be a step missing in the documentation where it tells you how to make DRBD use both NICs and not just the preferred one.
