Post Problem Starting Backup Server After Upgrade Again
Hey guys,

I'm having the same problem I had a little while ago with the backup not starting after an upgrade, the issue was resolved before here:

http://www.inductiveautomation.com/forum/viewtopic.php?f=72&t=7897

by copying the module folder from the primary server to the backup server but that is not fixing the issue this time. The only difference is that now I have the SPC module installed on the primary server for testing. Those modules are now on the backup server as well (because I copied the folder over) but according to the wrapper.log file it's still trying to do a full restore for some reason. Can anyone see anything else that could be wrong?

Try shutting down the backup server, and delete the contexts of data/db, but keep the folder
Then edit redundancy.xml and delete the systemstateuid line, then restart

I tried that and it still does the same thing.

Ok, this is weird.... I uninstalled all of the OEE/Downtime modules off of the primary but kept the SPC modules, copied over the modules folder from the primary to the backup and then did everything that Kyle had suggested again and this time it worked. Not sure why that is... apparently it didn't like something with the OEE modules. FYI.

On the master node, I believe it should have logged a message along the lines of "Backup node's module manifest is incompabile with the master's..." with details of the module versions. If you can locate that in the wrapper.log file, it might help us track down what was going on.

Thanks,
