Thanks, Eugen. I’m afraid I haven’t yet found a way to either disable the CephPGImbalance alert or change it to handle different OSD sizes. Changing /var/lib/ceph/<cluster_id>/home/ceph_default_alerts.yml doesn’t seem to have any effect, and I haven’t even managed to change the behavior from within the running prometheus container.
If you have a functioning workaround, can you give a little more detail on exactly what yaml file you’re changing and where?
