So the error you reported first is now resolved? What does the mirror
daemon log?
Zitat von Michel Niyoyita <micou12@xxxxxxxxx>:
I have configured it as follow :
ceph_rbd_mirror_configure: true
ceph_rbd_mirror_mode: "pool"
ceph_rbd_mirror_pool: "images"
ceph_rbd_mirror_remote_cluster: "prod"
ceph_rbd_mirror_remote_user: "admin"
ceph_rbd_mirror_remote_key: "AQDGVctluyvAHRAAtjeIB3ZZ75L8yT/erZD7eg=="
ceph_rbd_mirror_remote_mon_hosts: "mon-ip:3300"
This the configs of rbdmirrors.yml

You didn't answer if the remote_key is defined. If it's not then your
rbd-mirror daemon won't work which confirms what you pasted (daemon
health: ERROR). You need to fix that first.
