Re: [ceph-users] Migrating data from a Ceph clusters to another

According to: http://lists.ceph.com/pipermail/ceph-users-ceph.com/2016-May/009485.html it seems not entirely safe to copy an RBD pool this way. This thread mentions doing a rados ls and the get/put the objects but Greg mentioned that this may also have issues with snapshots. Maybe cppool has

Re: [ceph-users] Migrating data from a Ceph clusters to another

I'm not sure if this is what you need, but I recently tried 'rados cppool ' to populate a new test-pool with different properties. I simply needed some data in there, and this command for me. Regards, Eugen Zitat von 林自均 : Hi Irek & Craig, Sorry, I misunderstood

Re: [ceph-users] Migrating data from a Ceph clusters to another

Hi Irek & Craig, Sorry, I misunderstood "RBD mirroring". What I want to do is not like that. I just want to move all the data from a cluster to another. It can be achieved by `rados -p get ` for all objects on cluster A, and then `rados -p put ` on cluster B. Is there any tool for that?

Hi, Sorry I gave the wrong feature. rbd mirroring method can only be used on rbd with "journaling" feature (not layering). Sincerely, Craig Chi On 2017-02-09 16:41, Craig Chiwrote: > Hi John, > > rbd mirroring can configured by >

Re: [ceph-users] Migrating data from a Ceph clusters to another

Hi John, rbd mirroring can configured by pool.http://docs.ceph.com/docs/master/rbd/rbd-mirroring/ However the rbd mirroring method can only be used on rbd with layering feature, it can not mirror objects other than rbd for you. Sincerely, Craig Chi On 2017-02-09 16:24, Irek

Hi. I recommend using rbd import/export. С уважением, Фасихов Ирек Нургаязович Моб.: +79229045757 2017-02-09 11:13 GMT+03:00 林自均 : > Hi, > > I have 2 Ceph clusters, cluster A and cluster B. I want to move all the > pools on A to B. The pool names don't conflict between

[ceph-users] Migrating data from a Ceph clusters to another

Hi, I have 2 Ceph clusters, cluster A and cluster B. I want to move all the pools on A to B. The pool names don't conflict between clusters. I guess it's like RBD mirroring, except that it's pool mirroring. Is there any proper ways to do it? Thanks for any suggestions. Best, John Lin
