It looks like all string-based config overrides for RBD are ignored: 2020-07-29T08:52:44.393-0400 7f2a97fff700 4 set_mon_vals failed to set rbd_default_data_pool = rbd-data: Configuration option 'rbd_default_data_pool' may not be modified at runtime librbd always accesses the config options in a thread-safe manner, so I'll open a tracker ticket to flag all the RBD string config options are runtime updatable (primitive data type options are implicitly runtime updatable). > I tried: > > $ ceph config set client rbd_default_data_pool rbd-data > $ ceph config set global rbd_default_data_pool rbd-data > > They both show up under: > > $ ceph config dump > > However, newly created RBD images with the 'rbd' CLI tool do not use the > data pool. > > If I set this in ceph.conf it works: > > [client] > rbd_default_data_pool = rbd-data > > Somehow librbd isn't fetching these configuration options.
