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 Michel On Tue, Feb 13, 2024 at 4:07 PM Eugen Block <eblock@nde.ag> wrote:
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.
Michel

Did you define ceph_rbd_mirror_remote_key? According to the docs [1]:
ceph_rbd_mirror_remote_key : This must be the same value as the user ({{ ceph_rbd_mirror_local_user }}) keyring secret from the primary cluster.

Hello team,
I have two clusters in testing environment deployed using ceph-ansible running on ubuntu 20.04 with ceph Pacific version . I am testing mirroring between two clusters , in pool mode . Our production Cluster is for backend storage for openstack. This is how I configured the rbdmirros.yml:
ceph_rbd_mirror_configure: true ceph_rbd_mirror_mode: "pool" ceph_rbd_mirror_remote_cluster: "prod" ceph_rbd_mirror_remote_user: "admin"
This is my primary cluster "/etc/ceph/ "directory:
root@ceph-osd1:/etc/ceph# ls -l total 52 -r-------- 1 root root 151 Feb 13 08:47 bup.client.admin.keyring -rw-r--r-- 1 root root 866 Feb 13 08:45 bup.conf -r-------- 1 ceph ceph 151 Feb 12 13:35 ceph.client.admin.keyring -rw------- 1 ceph ceph 131 Feb 12 13:41 ceph.client.crash.keyring -rw-r--r-- 1 ceph ceph 863 Feb 12 13:35 ceph.conf -rw-rw-r-- 1 ceph ceph 1294 Feb 12 13:40 ceph-dashboard.crt -rw------- 1 ceph ceph 1704 Feb 12 13:40 ceph-dashboard.key -r-------- 1 ceph ceph 140 Feb 12 13:36 ceph.mgr.ceph-osd1.keyring -r-------- 1 ceph ceph 140 Feb 12 13:36 ceph.mgr.ceph-osd2.keyring -r-------- 1 ceph ceph 140 Feb 12 13:36 ceph.mgr.ceph-osd3.keyring -r-------- 1 root root 151 Feb 13 08:38 prod.client.admin.keyring -rw-r--r-- 1 root root 863 Feb 13 08:37 prod.conf -rw-r--r-- 1 root root 92 Aug 29 16:38 rbdmap
and this is my secondary "/etc/ceph" directory:

The offending line appears to be:
