Hi, >“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.” Shouldn’t it be possible to just do the “ceph osd tier add ecpool cachepool && ceph osd tier cache-mode cachepool writeback” and let Ceph redirect the requests (CephFS or other) to the
cache pool? Cheers, Maxime From:
ceph-users <ceph-users-bounces@xxxxxxxxxxxxxx> on behalf of David Turner <david.turner@xxxxxxxxxxxxxxxx> 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.

Resnick [rresnick@xxxxxxx] 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?
