I am not able to access the link. Seems like the server is down. Is there any other link to access this doc? Thanks, Tejas Doc looks good to me. Moving to verified. |
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: https://access.redhat.com/documentation/en/red-hat-ceph-storage/2/paged/block-device-guide/chapter-4-block-device-mirroring 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.
