[ceph-users] cephfs:: store files on different pools?

Hi! is is (technically) possible to instruct cephfs to store files < 1Mib on a (replicate) pool and the others files on another (ec) pool? And even more, is it possible to take the same kind of decision on the path of the file? (let's say that critical files with names like r"/critical_path/critical_.*" i want them in a 6x replication ssd pool) Thank you! Adrian
