sudo ceph tell osd.\* injectargs '--osd_max_backfills 4'
sudo ceph tell osd.\* injectargs '--osd_heartbeat_interval 15'
sudo ceph tell osd.\* injectargs '--osd_recovery_max_active 4'
sudo ceph tell osd.\* injectargs '--osd_recovery_op_priority 63'
sudo ceph tell osd.\* injectargs '--osd_client_op_priority 3'
