Is it possible to reconfigure a filesystem with a
default EC pool to a
default replicated pool?
Patrick Donnelly answered this question on 3/4/20
"You must create a new file system at this time. Someday we would like
to change this but there is no timeline."
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:

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

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 :-/
