Description of problem:
While creating a rbd-mirror relationship between 2 cluster where both clusters have encrypted OSDs, we need a few additional steps.
This is needed because when encrypted OSDs are present we cannot name the clusters as we want. ( Refer https://bugzilla.redhat.com/show_bug.cgi?id=1391920 ) And due to this both clusters will have name Ceph.
This is needed only till the mentioned BZ is resolved.
In this doc:
There are 2 separate cluster names used, but when both the cluster names are the same, we need 3 additional steps to configure rbd-mirror:
1. Change the name of the cluster in the /etc/sysconfig/ceph file on the rbd-mirror node on cluster A (ex: CLUSTER=master )
1a. On ubuntu change the cluster name /etc/default/ceph file.
2. Create a symlink to the ceph.conf file ex: ln -s ceph.conf master.conf only on the mirror node on cluster A.
3. Use the symlink files in all the rbd-mirror setup. Ex: 'ceph -s' ans 'ceph -s --cluster master' now refer to the same cluster.
Please add a note somewhere in the rbd-mirror segment to reflect this.
I am not able to access the link. Seems like the server is down.
Is there any other link to access this doc?
Doc looks good to me.
Moving to verified.
