Ceph in general implements cluster-wide POSIX file locks, internally managing the locks based on the same clustering & distribution mechanisms as it uses for coordinating its own work. From the view pointer of a filesystem user, it should "just work", though naturally with network operations latency is higher than with purely local locks. The cfuse client does not support them, currently. This is merely a case of "oh nobody wrote that code yet".
