If you only configured 1 iscsi gw but you see 3 running, have you
tried to destroy them with 'cephadm rm-daemon --name ...'? On the
active MGR host run 'journalctl -f' and you'll see plenty of
information, it should also contain information about the iscsi
deployment. Or run 'cephadm logs --name <iscsi-gw>'.
Zitat von "Paul Giralt (pgiralt)" <pgiralt@xxxxxxxxx>:
This was working until recently and now seems to have stopped
working. Running Pacific 16.2.5. When I modify the deployment YAML
file for my iscsi gateways, the services are not being added or
removed as requested. It’s as if the state is “stuck”.
At one point I had 4 iSCSI gateways: 02, 03, 04 and 05. Through some
back and forth of deploying and undeploying, I ended up in a state
where the services are running on servers 02, 03, and 05 no matter
what I tell cephadm to do. For example, right now I have the
following configuration:
service_type: iscsi
service_id: iscsi
placement:
hosts:
- cxcto-c240-j27-03.cisco.com
spec:
pool: iscsi-config
… removed the rest of this file ….
However ceph orch ls shows this:
[root@cxcto-c240-j27-01 ~]# ceph orch ls

Notice it shows 3/1 because the service is still running on 3
servers even though I’ve told it to only run on one. If I configure
all 4 servers and apply (ceph orch apply) then I end up with 3/4
because server 04 never deploys. It’s as if something is “stuck”.
Any ideas where to look / log files that might help figure out
what’s happening?
