I asked the same not so long ago, check archive, quite usefull replies. -----Original Message----- Sent: 19 February 2020 14:20 To: ceph-users@xxxxxxx Subject: Migrating/Realocating ceph cluster Hi, I am looking for a good way of migrating/realocating ceph cluster. It has about 2PB net, mainly RBD, but object storage is also used. The new location is far away about 1,500 kilometers. Of course I have to minimize the downtime of the cluster :) Right now I see following scenarios: 1. Build identical cluster. Freeze the source. Copy everything with cppool/rbd mirror. Relocate servers and the power on them. 2. Run cluster mirroring over network. 3. Using cache tier. I'm starting research about this migration, so probably some of the solutions above are unfeasible. Maybe somebody has experience about migration between DC? Any new ideas? Thougths?
