Do a "ps auwwx" to see how a running monitor was started and use the equivalent command to try to start the MON that won't start. "ceph-mon --help" will show you what you need. Most important is to get the ID portion right and to add "-d" to get it to run in teh foreground and log to stdout. HTH and good luck!

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.
