Update: This is resolved.
There were 2 issues:
I had the wrong mysql username/password in Config.class.php on the nodes. During the node install, I had given it a generic root account but found out earlier today that I specifically needed the username/password for storage nodes, which I found under the storage node section in settings on the main server.
Second: I realized the nodes couldn’t even connect to the main database, and I was able to narrow that down to the my.cnf file on the main server. It had the bind address set to 127.0.0.1. I commented that line out, restarted mysql, and then they were able to connect.
After I verified everything was talking correctly, I restarted the FOGImageReplicator service and everything instantly started copying. The fogreplicator.log file on Node1 shows Group #2 as I expected it might.
This also fixed an issue that I never really cared about enough to fix… On the main fog dashboard page under disk information, It always told me “Failed to connect to” when I selected Node1 or Node2. that’s fixed now and I can see the disk usage for them.
Thanks for the help!
