proper way to do defrag of a mountpoint
Usage: "glusterfs-defrag <MOUNTPOINT>" there are new features added to distribute with this patch: * bash# getfattr -n trusted.distribute.linkinfo <file> Gives output in the format "<hostname>:<directory>", if there is a linkfile present, where hostname is server, directory is backend directory where the actual linkfile is present. * bash# getfattr -n trusted.glusterfs.pathinfo <path> Gives layout information if directory, and info about actual location of file in backend servers, in the form of 'hostname:directory'. (TODO: should extend it to all xlators) * bash# getfattr -n trusted.distribute.fix.layout <path> scales out the directory layout in distribute, so when new servers are added, layouts are fixed to include them. * removed '' as its no more required. * changed '' to have a feature to specify target bricks, so defrag happens to only those nodes. moved the file to 'glusterfs-defrag', which now gets installed to '${prefix}/bin' * storage/posix: takes new option 'hostname' so it can resolve to same hostname given during 'gluster volume create'. with 'trusted.glusterfs.pathinfo' posix returns the value in 'hostname:real_path' format.
