Please note that the "ls -lR" is only needed to trigger self-heal pre-emptively. Even if you don't do it, replicate will at all times serve read requests from the up-to-date copy, and any access to a file will automatically trigger self-heal. I do agree, however, that a way to monitor the state would be helpful. ------------------------------ Vikas Gorur Engineer - Gluster, Inc. ------------------------------ _______________________________________________ Gluster-users mailing list Gluster-users@gluster.org http://gluster.org/cgi-bin/mailman/listinfo/gluster-users
