it is better to stop the clients who writes to ceph cluster prior to
turning of the cluster
i might be stating the obvious
if this is openstack cluster who uses the ceph cluster -> Shif the client
to write to replicated cluster , or divert the traffic to a replicated site.
the same for k8s cluster
cd
this way the perfromance of etcd will boost
but again not good for production :)

you can see example below of changing it on the fly
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'
