SDN is applied with errors

[vlayerc]

...and dont working



Hello!

I updated according to the recommendations in the official documentation https://pve.proxmox.com/pve-docs/chapter-pvesdn.html#pvesdn_installation.

Made a test Simple SDN and when applying it I get Warning:

WARN: missing 'source /etc/network/interfaces.d/sdn' directive for SDN support!
Removed “/etc/systemd/system/multi-user.target.wants/dnsmasq@test.service”.
Could not configure subnet test-192.168.22.0-24: No gateway defined for subnet test-192.168.22.0-24 at /usr/share/perl5/PVE/Network/SDN/Dhcp/Dnsmasq.pm line 128.


Created symlink /etc/systemd/system/multi-user.target.wants/dnsmasq@test.service -> /lib/systemd/system/dnsmasq@.service.


TASK WARNINGS: 1

Accordingly, Status = error

Specified source /etc/network/interfaces.d/*

under /etc/network/interfaces.d/ there is a sdn config file with the following contents

#version:9

auto test
iface test
    bridge_ports none
    bridge_stp off
    bridge_fd 0

Why might this be happening?

Thank you!

It seems like you have automatic DHCP active, but no gateway configured in the subnet.

Hi,

had the same thing on one of my nodes.
Check if in the file /etc/network/interfaces contains the following line:

source /etc/network/interfaces.d/*

Yes, of course, it exists.


Added an alias to SDN->VNets and the error changed

Removed "/etc/systemd/system/multi-user.target.wants/dnsmasq@test.service".

I removed the DHCP and applied the configuration.
I saw another error below. Or do you mean different by your message?

WARN: missing 'source /etc/network/interfaces.d/sdn' directive for SDN support!
Removed "/etc/systemd/system/multi-user.target.wants/dnsmasq@test.service".

Thank you!

Yes, the error is gone now, regarding the remaining warning can you please post the contents of your /etc/network/interfaces ?

 

[vlayerc]

Some observation. I have a cluster of 2 servers. one has pve 8.2 and the other 8.0.

Does it make any difference in this case?

In subnets I removed also srcnat and now have the following:

WARN: missing 'source /etc/network/interfaces.d/sdn' directive for SDN support!

You have a typo in your interfaces file:

souce /etc/network/interfaced.d/*

should be:

source /etc/network/interfaces.d/*

Oh, my God. Thank you so much, it was my rush.
Thank you for your time!
Have a good day! It's working.
