Well, nc would not tell you if a bad (local or remote) firewall
configuration prevented nc (and ceph -s) from connecting, it would
give the same results as if the daemon wasn't listening at all, so
that is why I suggested checking if the port was listening or not,
instead of doing a wide test that may have multiple causes for same
failure.
Understood, you're right.
so if 192.168.14.48 indeed is a mon host, then "systemctl" should show
if the ceph-mon@<my-hostname> is running or not,
root@mon01:~# systemctl status ceph-mon@mon01
Unit ceph-mon@mon01.service could not be found.
But here I see all are running:
root@mon01:~# systemctl list-units --type=service | grep ceph

Doesn't exist:
root@mon01:~# ls -l /var/log/ceph/
total 988
drwxrwx--- 2 167 167 4096 Jan 5 13:50 b61400fe-[...]
-rw-r--r-- 1 ceph ceph 872301 Jan 10 16:57 cephadm.log
-rw-r--r-- 1 ceph ceph 123769 Jan 5 13:50 cephadm.log.1
Inside the b61400fe-... subdir there is only ceph-volume.log. This now
makes me curious:
ceph_volume.exceptions.ConfigurationError: Unable to load expected Ceph
config at: /etc/ceph/ceph.conf
But ceph.conf exists:
root@mon01:~# ls -l /etc/ceph/ceph.conf
-rw-r--r-- 1 root root 177 Jan 5 13:49 /etc/ceph/ceph.conf
Why so? The file is 644, /etc/ceph is 755, as is /etc, so the file is
world readable.
I googled of course, and found a bug report [1], but no further info
about it.
Others seem to have the same issue, but it is not clear to me how to
track down what's up & how to fix it.
