Hi Michel, This is expected behaviour. As described in Nautilus release notes [1], the `target_max_misplaced_ratio` option throttles both balancer activity and automated adjustments to pgp_num (normally as a result of pg_num changes). Its default value is .05 (5%). Use `ceph osd pool ls detail` to monitor your pool's pg_num and pgp_num values. They should gradually be increasing towards 256.
