Unless you find a key on the compute like (something with crowbar-$ID)

# virsh secret-list 
 UUID                                  Usage
--------------------------------------------------------------------------------
 5b7c1b36-9093-4a13-b14d-da8b8cbdd8a6  ceph crowbar-5b7c1b36-9093-4a13-b14d-da8b8cbdd8a6 secret

you can/have to fix it on your own:

#!/bin/bash

ID="5b7c1b36-9093-4a13-b14d-da8b8cbdd8a6"
# get cinder key from ceph cluster - ceph auth get-key client.cinder
CINDERKEY="AQA4cw1aa2tAAhAAxYl2l/lCaer3squRBdXBYg=="
FILE="<secret ephemeral='no' private='no'><uuid>$ID</uuid><usage type='ceph'><name>client.cinder secret</name></usage></secret>"
FILENAME="/tmp/secret.xml"

for host in 01 02 03 04 05; do
	dest="compute${host}"
	echo "Verifiy host $dest:"
	if ! ssh $dest virsh secret-get-value $ID; then
		echo "Create secret for cinder user."
		ssh $dest "echo \"$FILE\" > $FILENAME"
		ssh $dest virsh secret-define --file $FILENAME
		ssh $dest virsh secret-set-value --secret $ID --base64 $CINDERKEY
	fi
	echo "ok!"	
done
