MJ; Assuming that you have a replicated pool with 3 replicas and min_size = 2, I would think stopping 2 OSD daemons, or 2 OSD containers would guarantee HEALTH_ERR. Similarly, if you have a replicated pool with 2 replicas, still with min_size = 2, stopping 1 OSD should do the trick. Thank you, Dominic L.

To get HEALTH_WARN we always simply set something like noout, but we also wonder if there's a nice way to set HEALTH_ERR, for the same purpose.
