I use CephFS on erasure coding at home using a cache tier. It works fine for my use case, but we know nothing about your use case to know if it will work well for you. The answer as to how to move an existing cephfs pool from replication to erasure coding (and vice versa) is to create the new pool and rsync your data between them. ________________________________ [cid:image75705d.JPG at 8b6af7ae.4c8fbdce]<https://storagecraft.com> David Turner | Cloud Operations Engineer | StorageCraft Technology Corporation<https://storagecraft.com> 380 Data Drive Suite 300 | Draper | Utah | 84020 Office: 801.871.2760 | Mobile: 385.224.2943 ________________________________ If you are not the intended recipient of this message or received it erroneously, please notify the sender and delete it, together with any attachments, and be advised that any dissemination or copying of this message is prohibited. ________________________________ ________________________________ From: ceph-users [ceph-users-bounces@xxxxxxxxxxxxxx] on behalf of Rhian Resnick [rresnick at fau.edu] Sent: Wednesday, March 08, 2017 12:54 PM To: ceph-users at ceph.com Subject: cephfs and erasure coding Two questions on Cephfs and erasure coding that Google couldn't answer. 1) How well does cephfs work with erasure coding? 2) How would you move an existing cephfs pool that uses replication to erasure coding?
