Sebastian,
I appreciate all your help. I actually (out of desperation) spun up
another cluster, same specs, just using Ubuntu 18.04 rather than Debian
10. All the OSDs were recognized, and all went up/in without issue.
Thanks

You only need to create the keyring, you don't need to store the
keyring anywhere. I'd still suggest to somehow create the keyring, but
I haven't seen this particular error before.

Hello all,
Running into some issues trying to build a virtual PoC for Ceph.
Went to my cloud provider of choice and spun up some nodes. I have
three identical hosts consisting of:
Debian 10
8 cpu cores
16GB RAM
1x315GB Boot Drive
3x400GB Data drives
After deploying Ceph (v 16.2.5) using cephadm, adding hosts, and
logging into the dashboard, Ceph showed 9 OSDs, 0 up, 9 in. I
thought perhaps it just needed some time to bring up the OSDs, so I
left it running overnight.
This morning, I checked, and the Ceph dashboard shows 9 OSDs, 0 up,
6 in, 3 out. I find this odd, as it hasn't been touched since it
was deployed. Ceph health shows "HEALTH_OK", `ceph osd tree` outputs:
ID CLASS WEIGHT TYPE NAME STATUS REWEIGHT PRI-AFF
-1 0 root default
0 0 osd.0 down 0 1.00000
1 0 osd.1 down 0 1.00000
2 0 osd.2 down 0 1.00000
3 0 osd.3 down 1.00000 1.00000
4 0 osd.4 down 1.00000 1.00000
5 0 osd.5 down 1.00000 1.00000
6 0 osd.6 down 1.00000 1.00000
7 0 osd.7 down 1.00000 1.00000
8 0 osd.8 down 1.00000 1.00000
and if I run `ls /var/run/ceph` the only thing it outputs is
"d1405594-0944-11ec-8ebc-f23c92edc936" (sans quotes), which I
assume is the cluster ID? So of course, if I run `ceph daemon osd.8
help` for example, it just returns:
Can't get admin socket path: unable to get conf option admin_socket
for osd: b"error parsing 'osd': expected string of the form
TYPE.ID, valid types are: auth, mon, osd, mds, mgr, client\n"
If I look at the log within the Ceph dashboard, no errors or
warnings appear. Will Ceph not work on virtual hardware? Is there
something I need to do to bring up the OSDs?
Just as I was about to send this email I went to check the logs and
it shows the following (traceback ommited for length):
8/30/21 7:44:15 AM[ERR]Failed to apply osd.all-available-devices

DriveGroupSpec(name=all-available-devices->placement=PlacementSpec(host_pattern='*'),

and similar for the other OSDs. I'm not sure why it's complaining
about auth, because in order to even add the hosts to the cluster I
had to copy the ceph public key to the hosts to begin with.
