For a variety of reasons, none good anymore, we have two separate Ceph clusters. I would like to merge them onto the newer hardware, with as little downtime and data loss as possible; then discard the old hardware. Cluster A (2 hosts): - 3TB of S3 content, >100k files, file mtimes important - <500GB of RBD volumes, exported via iscsi Cluster B (4 hosts): - <50GiB of S3 content - 7TB of RBD volumes, exported via iscsi Short of finding somewhere to dump all of the data from one side, and re-importing it after merging with that cluster as empty; are there any other alternatives available to me? -- Robin Hugh Johnson Gentoo Linux: Developer, Infrastructure Lead E-Mail : robbat2 at gentoo.org GnuPG FP : 11ACBA4F 4778E3F6 E4EDF38E B27B944E 34884E85
