Re: Removing Rados Gateway in ceph cluster

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.

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 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 .

Hi,

can you paste the output of:

ceph config dump | grep mgr/dashboard/RGW_API_HOST

Does it match your desired setup? Depending on the ceph version (and
how ceph-ansible deploys the services) you could also check:

ceph dashboard get-rgw-api-host

I'm not familiar with ceph-ansible, but if you shared your rgw
definitions and the respective ceph output we might be able to assist
resolving this.

Regards,
Eugen
