OK, fair enough. So I tried adding "allow_dirfrags" which gives me:
ceph fs set cephfs allow_dirfrags true
Directory fragmentation is now permanently enabled. This command is
DEPRECATED and will be REMOVED from future releases.
And I enabled snapshot support:
ceph fs set cephfs allow_new_snaps true
enabled new snapshots
However, this has not changed the "flags" of the filesystem in any way.
So I guess there are still features not enabled that are enabled on
newly installed clusters. Where can I find a list of features that I can
enable? I have searched through documentation but I don't see anything
related. It's also not described / suggested in the part about upgrading
the MDS cluster (IMHO that would be a logical place) [1].
