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 'scale-n-defrag.sh' as its no more required.
* changed 'defrag.sh' 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.
