- Once upgraded I discovered that daemon runs under ceph. I just ran chown on ceph directories. and it worked.
- Firewall is fully disabled. Checked connectivity with nc and nmap.
- Configuration seems to be right. I can post if you want.
- Enabling logging on OSD shows that for example osd.1 is reconnecting all the time.

- I rebooted all services at once for it to have available all OSD at the same time and don't mark it down. Don't work.
- I forced up from commandline. ceph osd in 1-5. They appear as in for a while then out.
- We tried ceph-disk activate-all to boot everything. Don't work.
The strange thing is that culster started worked just right after upgrade. But the systemctrl command broke both servers.
