Hi all,
I m looking for a method to transfer ceph cluster. Now the cluster is located in network1 that has hosts A, B, C... And the target is to transfer it to network2 that has hosts a,b,c... What I can think of, is adding hosts a, b, c into the current cluster like adding OSD and MON. Then after the data has been rebalanced, down OSD and MON on hosts A,B,C Then the question would be how to know the old OSD could be safely down? This method causes too much redundant operations, other than creating OSD or MON, in the new environment, should I also create PGs and POOLs just like the old cluster has? Is there a more direct way to shift cluster from old network and hosts to a new one? Thanks!
