> Whenever an entity is the master gluster volume is changed (writes) the
> marker xlator (feature/marker) updates the xtime extended attribute for
> that particular file and propagates it up the directory hierarchy. This by
> looking at the top level directory (xtime-master > xtime-slave) gsyncd
> knows whether there some change in the tree. Gsyncd then recursively walks
> the tree (only entering sub-directories that satisfy xtime(M) > xtime(S))
> to get a list of files that have xtime differences b/w master and slave.

> Is this in real time?
