Description Vasishta 2023-01-02 09:07:54 UTC 
Description of problem:
Tried ceph orch host drain on a node with active mgr, though eventually mgr was moved to different host and a new standby mgr was configured, the mgr daemon on the host was reported stray for a while.

>>    health: HEALTH_WARN
>>            Failed to apply 2 service(s): mds.cephfs,mon
>>            1 stray daemon(s) not managed by cephadm

Detail
>> [WRN] CEPHADM_STRAY_DAEMON: 1 stray daemon(s) not managed by cephadm
>>    stray daemon mgr.e22-h18-b01-fc640.rdu2.scalelab.redhat.com.quesrw on host e22-h18-b01-fc640.rdu2.scalelab.redhat.com not managed by cephadm

This BZ is to improve handling and/or reporting in a better way that cluster health doesn't raise flags that daemons are stray as this is a planned maintenance activity.
 
Version-Release number of selected component (if applicable):
16.2.10-87.el8cp

How reproducible:
Tried once.

Steps to Reproduce:
1. Configure cluster and drain node with active mgr.

Actual results:
(Explained above)

Expected results:
Report activities being performed in nicer way as the daemon ging stray is due to planned maintenance activity. 

Additional info:
# ceph orch host drain e22-h18-b01-fc640.xxx.xxx.xxx.com
Scheduled to remove the following daemons from host 'e22-h18-b01-fc640.xxx.xxx.xxx.com'
