Ceph » rgw

Running a 3-node cluster in a lab environment running on ceph version 14.2.9 (containerized). Each node is running a OSD, MON, MGR, MDS and 2 x RGW (we're using a second RGW instance to host a pubsub endpoint).

Can I confirm that after it's no longer supported to list the events in the pubsub subscription via the command line?

I'm trying two methods:

1) As documented here: https://docs.ceph.com/docs/master/radosgw/pubsub-module/

$ radosgw-admin subscription pull --uid={user-id} --subscription={topic-name}

returns "ERROR: invalid flag --subscription={topic-name}". If I revert to --sub-name instead, I get "unrecognized arg subscription"

2) On older versions of nautilus we were using

$ radosgw-admin pubsub sub pull --sub-name <subname>--uid <username> --rgw-zone <zone>

but this now returns a large stack trace:

Is the only supported way to list these events via the REST API?

Thanks in advance,
