"You must create a new file system at this time. Someday we would like to change this but there is no timeline."
I'd be great if this is coming in one of the coming releases. Thanks Dietmar
I'm sure a lot of other people are in the same situation as us and would +1 this request. I guess the devs are super busy getting Octopus ready.

This is the eighth update to the Ceph Nautilus release series. This release fixes issues across a range of subsystems. We recommend that all users upgrade to this release. Please note the following important changes in this release; as always the full changelog is posted at: https://ceph.io/releases/v14-2-8-nautilus-released
Notable Changes ---------------
[....]
* CephFS: multiple active MDS forward scrub is now rejected. Scrub currently only is permitted on a file system with a single rank. Reduce the ranks to one via `ceph fs set <fs_name> max_mds 1`.
* Ceph now refuses to create a file system with a default EC data pool. For further explanation, see: https://docs.ceph.com/docs/nautilus/cephfs/createfs/#creating-pools
Is it possible to reconfigure a filesystem with a default EC pool to a default replicated pool?
According to https://docs.ceph.com/docs/nautilus/cephfs/createfs/#creating-pools it should give a better performance. Unfortunately we created the fs with a default EC pool 2 years ago, and back then this was possible and there was no suggestion to use a default replicated pool and than add the EC pool. We did exactly the oder way around :-/
Best Dietmar
