Have you tried to list your ceph keys with "/usr/bin/ceph config-key ls" ?
2017-09-11 15:56 GMT+05:00 M Ranga Swami Reddy <swamireddy@xxxxxxxxx>:
ceph-disk --prepare -dmcrypt --> cmd, where this command store the

default as per the docs - /etc/ceph/dmcrypt-keys -> but this directory is empty.
Thanks
Swami
