Sounds like ceph-ansible only supports one pool? I don't know, I've
never used ceph-ansible. But if it created a rbd-mirror setup
successfully you should be able to configure more pools to be mirrored
manually as described in the docs [1].

Thank you Eugen , all errors have been solved now is syncing on pool mode
level , I am trying to use two or more pools but I sill able using the
first one defined as it is in this configurations:
ceph_rbd_mirror_configure: true
ceph_rbd_mirror_mode: "pool"
ceph_rbd_mirror_pool: "data"
ceph_rbd_mirror_pool: "data_tes1"
ceph_rbd_mirror_remote_cluster: "site-a"
ceph_rbd_mirror_remote_user: "client.site-a"
ceph_rbd_mirror_remote_key: "AQB+wc1l4SFqNBAAG2I18SjJcnMN/wP/xdAUNw=="
ceph_rbd_mirror_remote_mon_hosts: "mon-ip:3300"
here I am getting only data pool , data_tes1 is not syncing , I need a help
on how we can define more pools, because in our production cluster we have
4 pools images, volume .... which we want to backup.
Thank you for your help
Michel

So the error you reported first is now resolved? What does the mirror
daemon log?
