* DHT rename: Recreate linkfile after unlinkshishir gowda2011-08-031-3/+0
| | | | | | | | | | | | | This is done, so that there is no gfid mismatch. Unlink the older linkfile if it exists, and recreate it with the correct gfid. Also removed unused rename related code.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

| | | | | | | | | | | | | | | | We need to ensure that only the last subvolume's end-of-directory notification is respected so that directory reading does not stop before all subvolumes have been read. That could happen because the posix for each subvolume sends a ENOENT on end-of-directory but in distribute we're not concerned only with a posix's view of the directory but the aggregated namespace' view of the directory, which is maintained by distribute.
