Hi all,
We have a 200TB RBD image which we are replicating using RBD mirroring.
We want to test the DR copy and make sure that we have a consistent copy in
case primary site is lost.
We did it previously and promoted the DR copy which broken the DR copy from
primary and we have to resync
irror --cluster=cephdr"
Thanks,

Hi,
We are using Luminous and copying a 100TB RBD image to DR site using RBD
Mirror.
Everything seems to works fine.
The question is, can we mount the DR copy as Read-Only? We can do it on
Netapp and we are trying to figure out if somehow we can mount it RO on DR
site, then we can do backups at

Do the OSD daemon from primary and secondary have to talk to each other? we
have same non routed networks for OSD.

I could do ceph -s from both side and they can see each other. Only rbd

Hi there,
With default cluster name "ceph" I can map rbd-nbd without any issue.
But for a different cluster name, i'm not able to map image using rbd-nbd

We are using a rbd mapped image as a NFS backend(XFS) and sharing to NFS

This setup has been working fine.
Now we need to replicate this image to second cluster on the campus.
For replication to work, we need exclusive-lock and journaling feature to
be enabled.
