Upgraded all the OS's in the cluster to Ubuntu 14.04 LTS from Ubuntu 12.02 LTS then finished the upgrade from Firefly to Luminous.
I then tried to upgrade the first monitor to Ubuntu 16.04 LTS, the OS upgrade went fine, but then the monitor and manager wouldn't start. I then used ceph-deploy to install over the existing install to ensure the new packages were installed. Monitor and manager still wont start. Oddly enough, it seems that logging wont populate either. I was trying to find the command to run the monitor manually to see if could read the output since the logging in /var/log/ceph isn't populating. I did a file system search to see if a log file was created in another directory, but it appears that's not the case. Monitor and cluster were healthy before I started the OS upgrade. Nothing in "Journalctl -xe" other than the services starting up without any errors. Cluster shows 1/3 monitors down in health status though. I hope to upgrade all the remaining monitors to 16.04. I already upgraded the gateways to 16.04 without issue. All the OSDs are being replaced with newer hardware and going to CentOS 7.6.
