Description
This problem happened when I add Osds to the cluster.
The `ceph health detail` show that:
HEALTH_ERR Module 'cephadm' has failed: 'MegaSAS'
[ERR] MGR_MODULE_ERROR: Module 'cephadm' has failed: 'MegaSAS'
Module 'cephadm' has failed: 'MegaSAS'
The `ceph orch ls` show that:

AssertionError: MegaSAS
And the `ceph orch ps` show that there is a container named 'MegaSAS.log.bak' on the host `node4`. Neither can I find this docker container, nor can I deleted this service by command `ceph orch daemon rm MegaSAS.log.bak`.
I has tryed to excute command by `ceph mgr module disable cephadm` and `ceph mgr module enable cephadm`, bu useless.
My ceph version is v15.2.13 installed by cephadm.

I think something erroneous ended up in the config-key store. Could you give use the export of the config-key dump?
ceph config-key dump mgr/cephadm

Yes， you are right, I have found 'MegaSAS.log.bak' in the config-key.
Can I solve this problem by edit the config-key.
If I can, how to do it.
The command `ceph config-key dump mgr/cephadm` show a json data like this:

The "mgr/cephadm/host.wh-node04" is a string original, and I changed it to an object to have a better reading, and I hided other infomations.
The osd.45 and osd.54 are the new osds I add yesterday. It seemed that there were some tasks in the queue were blocked by this bug when I was applying new osds. I can only temporary solve it by excute command `ceph mgr module disable/enable cephadm`.
And I can't upgrade the ceph cluster by cephadm.
Hope to get your reply soon. Thanks.

you probably want to do:
1. Remove the MegaSys.log.bak file on node-04
2. run
$ ceph config-key set mgr/cephadm/pause true $ ceph-config-key rm mgr/cephadm/host.wh-node04 $ ceph mgr fail .....
3. Then wait a bit till, ceph -s no longer shows stray daemons, then
ceph orch resume

I had followed the steps as the suggests you gived me. The errors disappeared in a few seconds, and appeared again seconds latter.
This are the steps what I had done:
1. Rename the MegaSAS.log file to ___MegaSAS.log__ on node-04 2. ceph config-key set mgr/cephadm/pause true 3. ceph config-key get mgr/cephadm/host.wh-node04 4. delete the contents about ""MegaSAS.log.bak" from the json data of the config-key mgr/cephadm/host.wh-node04 5. ceph config-key set mgr/cephadm/host.wh-node04 with modified new contents 6. ceph mgr fail the active mgr daemon 7. ceph orch resume
And I also tried to `ceph config-key rm mgr/cephadm/host.wh-node04` instead of `ceph config-key set mgr/cephadm/host.wh-node04`, It's still no effect.
I found some new Traceback in the cephadm.log like this:
