Yes, sorry - I tried both 'ceph orch apply mgr "ceph01,ceph03"' and
'ceph orch apply mds "ceph04,ceph05"' before writing this initial email
- once again, the same logged message: "6/8/22 2:25:12 PM[INF]Saving
service mgr spec with placement ceph03;ceph01" but there's no messages
logged about attempting to create the mgr daemon.
I tried this at the same time that I tried ''ceph orch apply mgr
--placement=2' that I mentioned in my original email.
I think what I need is some advice on how to check cephadm's status - I
assume it should be logging every time it tries to deploy a new daemon
right? That should be my next stop, I think - looking at that log to see
if it's even trying. I just don't know how to get to that point.
And it's not just mgr daemons, it's any kind of daemon so far, is not
getting deployed.
But thank you for the advice, Dhairya.

Hi Zach,
Try running `ceph orch apply mgr 2` or `ceph orch apply mgr
--placement="<host1> <host2>"`. Refer this
<https://docs.ceph.com/en/latest/cephadm/services/#orchestrator-cli-placement-spec>
doc for more information, hope it helps.
Regards,

Our 16.2.7 cluster was deployed using cephadm from the start, but
now it
seems like deploying daemons with it is broken. Running 'ceph orch
apply
mgr --placement=2' causes '6/8/22 2:34:18 PM[INF]Saving service
mgr spec
with placement count:2' to appear in the logs, but a 2nd mgr does not
get created.
I also confirmed the same with mds daemons - using the dashboard, I
tried creating a new set of MDS daemons "220606" count:3, but they
never
got deployed. The service type appears in the dashboard, though, just
with no daemons deployed under it. Then I tried to delete it with the
dashboard, and now 'ceph orch ls' outputs:
NAME PORTS RUNNING REFRESHED AGE
PLACEMENT
mds.220606 0/3 <deleting> 15h
count:3
More detail in YAML format doesn't even give me that much information:
ceph01> ceph orch ls --service_name=mds.220606 --format yaml
service_type: mds
service_id: '220606'
service_name: mds.220606
placement:
count: 3
status:
created: '2022-06-07T03:42:57.234124Z'
running: 0
size: 3
events:
- 2022-06-07T03:42:57.301349Z service:mds.220606 [INFO] "service was
created"
'ceph health detail' reports HEALTH_OK but cephadm doesn't seem to be
doing its job. I read through the Cephadm troubleshooting page on
ceph's
website but since the daemons I'm trying to create don't even seem to
try to spawn containers (podman ps shows the existing containers just
fine) I don't know where to look next for logs, to see if cephadm +
podman are trying to create new containers and failing, or not
even trying.
