Well that's interesting. I don't have an explanation unfortunately.
You upgraded the MDS too, right? Only scenario that could cause this I
can think of is that the MDS were never restarted/upgraded to
nautilus.

Yes, the MDSes were upgraded and restarted for sure.


Operators should only care about "is X flag turned on" but we don't
really show that very well in the MDSMap dump. I'll make a note to
improve that. We'd really rather not that operators need to do bitwise
arithmetic on the flags bitfield to determine what features are turned
on.

Thanks.


I'll also add a note to list features that can be turned on:

OK.

ceph-fuse/kernel client don't use these flags. Only the MDS.


Check.
