Ok, I just found this message from Gregory Farnum : ? You can't use erasure coded pools directly with RBD. They're only suitable for use with RGW or as the base pool for a replicated cache pool, and you need to be very careful/specific with the configuration. I believe this is well-documented, so check it out! :) ? So, it's not usable to backup a production cluster. I have to use replicated pool.
