A couple of our nodes restarted unexpectedly and since the OSDs on those nodes will no longer authenticate with the MON.
I have tested that the node still has access to all the MON nodes using nc to see if the ports are open.
We can not find anything in the mon logs about authentication errors.
At the moment 50% of the cluster is down due to 2/4 nodes offline.

We have restarted the OSD nodes and this did not resolve the issue.
Confirmed that nodes have access to all mon servers.
I have looked in /var/run/ceph and the admin sockets are not there.
Here is output as its starting the OSD.

I'd appreciate it if you could let me know what I need to check.
The problem is probably with the account mongo is trying to launch with in your systemd mongod.service file. Check the user and group defined in the [Service] block are valid.
I tried to install mongoDB on Centos8, but when I run the command
systemctl status mongod.service
I get this error:

In some other posts, people told to try this command:
sudo chown -R mongodb:mongodb /var/lib/mongodb/
but in don't have the user mongodb and I get the error: invalid user: 'mongodb:mongodb'!
In my /etc/passwd file the only user for mongo is this:
mongod:x:994:992:mongod:/var/lib/mongo:/bin/false
What's the problem?
Why I cannot run mongod.service?
Thanks for your support.

about to fork child process, waiting until server is ready for connections.

For some kind of reason, mongod want the folder /data/db and ignore the file mongod.conf
After I created these folders, if I run mongod command (with sudo), programme start "correctly".
But if I reboot the system, the service fails on boot and continue to have problems.
I try to start service with mongo and get an error:

If I start mongod by manual, all works good.

Job for mongod.service failed. See 'systemctl status mongod.service' and 'journalctl -xn' for details.
[root#localhost ~]# systemctl status mongod.service -l

I configured SELinux to "enforcing" and I enabled the access to the port 27017 using
semanage port -a -t mongod_port_t -p tcp 27017
I can start the data base using this command:
[root#localhost ~]# sudo -u root /usr/bin/mongod --quiet --config /etc/mongod.conf
about to fork child process, waiting until server is ready for connections.

But still can't start it as a service :(
Any ideas of what I have missed?
