More info

Try renaming network.cfg which is in the flash drives config folder to network.cfg.bkp so you have a backup of your original network.cfg or make a copy and save it some where safe. If you don't care about saving it then just delete it. Then reboot which will install Unraid network defaults. In settings>network settings make sure enable bridging is set to yes and below it a network port is assigned like for example eth0. Array must be stopped to make changes to network settings.

I just rebooted again and this was in the log

 

Oct  1 20:29:55 Server root: /usr/sbin/libvirtd: error: Unable to initialize network sockets. Check /var/log/messages or run without --daemon for more info.

Use the terminal console and execute:

rm /var/lib/docker/network/files/local-kv.db /etc/rc.d/rc.docker restart

This will rebuild the docker network stack.

the command didnt work

 

so rebuilding the docker network stack works to restore the network bridge br0 but!! the fix does not survive a restart?? any thoughts

You could try rebuilding your docker file, If you delete the image and then restart docker it will create a new empty image. Settings>Docker Advanced View then you can go to the Previous Applications section of APPS and reinstall the containers.

 

You could also add the deletion of the file and docker restart to /etc/rc.local

rm /var/lib/docker/network/files/local-kv.db

/etc/rc.d/rc.docker restart

or

You could also add the User Scripts plugin then add it as a script in Settings>User Scripts and set the script to At First Array Start Only for schedule to run script on every reboot.

Update to the topic

 

So i bought a new dual port nic for unraid.  Installed the new nic with the on board nic disabled. booted unraid in gui mode. configured the dual port nic to load balancing so i can more speed and bandwidth.  rebooted and blam everything work as expected.  docker br0 show up in networks no issue's now.

 happy day in my server room.
