Hi,

Thank you.

Is there a recommended version of kernel for ubuntu 16.04 to be used with ceph 
fs from ceph release 14 ?

There isn't a "LTR" concept anymore in Ceph. There are three releases
that are supported at any given time. As soon as Octopus (15) will be
released Luminous (12) won't be (officially) supported anymore.

I would go for the latest release, Nautilus (14), when setting up a new
cluster. But if you want to go for a release that has been more battle
tested in production go for Mimic (13). It might also depend on your use
case: cephfs is proabably best served from Nautilus. Nautilus release
has improvements in all major interfaces (RGW, RBD, cephfs) though, but
might have some (undiscovered) issues.

Gr. Stefan
