New subject: Removing Rados Gateway in ceph cluster

6 Feb 2023

Please send responses to the mailing-list.

If the orchestrator is available, please share also this output (mask  
sensitive data):

ceph orch ls rgw --export --format yaml

Which ceph version is this? The command 'ceph dashboard  
get-rgw-api-host' was removed between Octopus and Pacific, that's why  
I asked for your ceph version.

I also forgot that mgr/dashboard/RGW_API_HOST was used until Octopus,  
in Pacific it's not applied anymore. I'll need to check how it is  
determined now.

   mgr        advanced  mgr/dashboard/ssl_server_port          8443

 for the second one it seems is not valid

 root@ceph-mon1:~# ceph dashboard get-rgw-api-host
 no valid command found; 10 closest matches:
 dashboard set-jwt-token-ttl <seconds:int>
 dashboard get-jwt-token-ttl
 dashboard create-self-signed-cert
 dashboard grafana dashboards update

 dashboard reset-account-lockout-attempts
 dashboard get-alertmanager-api-host
 dashboard set-alertmanager-api-host <value>
 dashboard reset-alertmanager-api-host
 Error EINVAL: invalid command
 root@ceph-mon1:~#

 Kindly check the output .

 Best Regards
