Hello Erik, We are going to use RBD-mirror to replicate the clusters. This seems to need separate cluster names. Kind regards, Glen Baars

It's no longer supported. It really only matters if you're running two or more independent clusters on the same boxes. That's generally inadvisable anyway.

It only affects nodes where they are collocated as they all use the "/etc/sysconfig/ceph" configuration file.

Is you rbd-mirror client also colocated with mon/osd? This needs to be changed only on the client side where you are doing mirroring, rest of the nodes are not affected? > > > > Is there a solution to this problem ? > > > > Best Regards > > Jocelyn Thode > > > _______________________________________________ > ceph-users mailing list > ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> > http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com > _______________________________________________ ceph-users mailing list ceph-users@lists.ceph.com<mailto:ceph-users@lists.ceph.com> http://lists.ceph.com/listinfo.cgi/ceph-users-ceph.com This e-mail is intended solely for the benefit of the addressee(s) and any other named recipient.
