Hi, It is not possible to change k/m on the fly. > Changing erasure-code-profile is not working so I assume that is only > template for newly created pools. > If it is not possible now is it planned in the feature (when)? Changing these parameters require a re-encoding of all objects. The interim solution is to create another pool and move all the objects from the first pool to the other. If disk space is an issue, a solution might be to define the old pool as a cache tier and evict its content to the storage tier. I did not test this though and there may be problems I do not yet see.
