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

So the error you reported first is now resolved? What does the mirror daemon log?
Zitat von Michel Niyoyita <micou12@gmail.com>:
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.

Thanks Eugen,
On my prod Cluster (as named it) this is the output the following command checking the status : rbd mirror pool status images --cluster prod health: WARNING daemon health: UNKNOWN image health: WARNING images: 4 total 4 unknown
but on bup cluster there are some errors which I am not able to fetch out: rbd mirror pool status images --cluster bup health: ERROR daemon health: ERROR image health: OK images: 0 total
so once create an images on the prod cluster , there is no syncing between two cluster . but I can create an image from one cluster to another which means there is communication between . but pool images is not syncing. Kindly if I miss something help me again.

Did you define ceph_rbd_mirror_remote_key? According to the docs [1]:
