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

be elsewhere in the file depending on the exact syntax problem.
The offending line appears to be:
