It seems that with Linux kernel 4.16.10 krdb clients are seen as Jewel
rather than Luminous. Can someone tell me which kernel version will be seen
as Luminous as I want to enable the Upmap Balancer.

4.13 or newer is enough for upmap

What will actually happen if an old client comes by, potential data damage - or just
broken connections from the client?

The latter (with "libceph: ... feature set mismatch ..." errors).
Thanks,

Upmap works the same for krbd and kcephfs. All upstream kernels
starting with 4.13 (and also RHEL/CentOS kernels starting with 7.5)
support it. If you have a choice which kernel to run, the newer the
better.
Thanks,
Ilya
