Description

In Reef 18.2.0 I deployed iscsi-gateways (although they're not maintained anymore). After removing the service successfully via dashboard, the service is still listed as "down" in the Dashboard > Block > ISCSI > Overview. Obviously, it appears in the cli as well:

$ ceph dashboard iscsi-gateway-list
{"gateways": {"iscsi-gateway.domain": {"service_url": "http://<user>:<pw>@<IP>:5000"}}}

Removing the gw works well:

$ ceph dashboard iscsi-gateway-rm iscsi-gateway.domain
Success

$ ceph dashboard iscsi-gateway-list
{"gateways": {}}

I believe this cleanup should work even if iSCSI is not really supported anymore. But since one still can deploy that service the removal should be consistent as well.

I tried the same procedure with both Pacific 16.2.13 and Quincy 17.2.6. For Pacific it seems to work as expected, for Quincy it doesn't. These are the logs from Quincy after removing the iscsi service (also via dashboard):

The message on Reef is basically the same, while on Pacific the removal works:

Apparently, Pacific uses the shortname for the gateway-add command while Quincy uses FQDN:

pacific:~ # ceph dashboard iscsi-gateway-list {"gateways": {"pacific": {"service_url": "http://test::5000"}}}

quincy:~ # ceph dashboard iscsi-gateway-list {"gateways": {"soc9-ceph.example.com": {"service_url": "http://user:user@192.168.124.186:5000"}}}

I update too soon, sorry for the spam. What I wanted to add is, while gateway-add command uses FQDN from Quincy onwards the gateway-rm command uses the shortname only. That's why it's failing to remove it from the dashboard.
