Hi,
I have checked the installed ceph version on each client and can confirm that it is: ceph version 12.2 luminous
This would drive the conclusion that the ouput of ceph daemon mon.<id> sessions is pointing incorrectly to "jewel".
I have the same in an upgraded Nautilus cluster. There are a couple of "unknown" clients and some Jewel clients, but checking those clients they all have at least Luminous. I rebooted some of those clients, too, but this didn't change anything. The min-compat-client already has been forced to luminous (knowing that in fact there are no jewel clients):
host1:~ # ceph osd get-require-min-compat-client luminous
I'd be curious how to get rid of the jewel client sessions.
