After one my SATA cables died to one of my cache drives (something that UnRaid did not alert me to or alter the UI, it showed a gray ball next to the drive and reported no errors despite /var/log/syslog screaming about superblock issues) I decided to upgrade UnRaid finally. I upgraded to the newest version and while I could connect to it from my local network I was unable to access the internet from the UnRaid box (it could still see/ping everything on the local network). My DNS servers were set to 8.8.8.8/8.8.4.4.

 

It appears that in the upgrade my default route was set to go through br1 (on 6.6.7 it is showing br0) and I think that was my issue but I wasn't clear on how to change that safely and how to revert back to br1 if my guess that it should be br0 was wrong. After a failed attempt to update the DNS and having to pull the USB drive off the motherboard to manually edit the network config I wasn't in a mood to attempt any new network-related fixes so I downgraded. Apart from the panic when it didn't show my cache drives and pretended like they were new drives I was able to get back up and running on 6.6.7.

 

My questions is: Why did UnRaid change my default route to br1 in the upgrade and if this is the root of my problem, like I think it is, how do I safely switch from br1 to br0?

 

I have included a screenshot of 6.6.7 (working) config. I sadly didn't screenshot the 6.9.2 config but I can confirm it said it was going through br1 for the default traffic and on the command line when I listed the routes (`ip route` is what I think I ran) it showed the br1 as "linkdown".

Sorry, I should have added a diagnostic from the start. I only have one from 6.6.7, I stupidly forgot to do one on 6.9.2 before I downgraded. If needed I can attempt another upgrade since I now have a clean up/downgrade path
