In the sample config for a 2-server mirror setup at: http://gluster.org/docs/index.php/Automatic_File_Replication_(Mirror)_across_Two_Storage_Servers both volumes are considered remote and use tcp as transport-type. If you intend to use a local volume as one of the 2 servers in a mirrored setup, is there any advantage in defining glusterfs.vol as below? volume remote type protocol/client option transport-type tcp option remote-host w.x.y.z option remote-subvolume brick end-volume volume posix type storage/posix option directory /localstoragedir end-volume volume local type features/posix-locks subvolumes posix end-volume volume replicate type cluster/replicate subvolumes local remote end-volume ======================== http://www.neotitans.com Web and IT Consulting
