Hi All,
I find myself in the position of having to change the k/m values on an ec-pool. I've discovered that I simply can't change the ec-profile, but have to create a "new ec-profile" and a "new ec-pool" using the new values, then migrate the "old ec-pool" to the new (see: https://ceph.io/en/news/blog/2015/ceph-pool-migration/ => Using Rados Export/Import).
Probably a better reference: https://docs.ceph.com/en/latest/rbd/rbd-live-migration/ Best check the docs for the ceph version you're using, e.g. Pacfic: https://docs.ceph.com/en/pacific/rbd/rbd-live-migration/ (I haven't attempted this myself.) Cheers, Chris
