"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

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

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:

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 :-/
