With one exception:
xfs_fsr ("filesystem reorganizer for XFS") which is hidden (on most
distros) in the "xfsdump"-package.It is a tool written by the xfs-developers, to defrag xfs-partitions. Most importantly it works (only) on mounted partitions! It can be run from cron, to walk all your xfs-partitions at night and continue where it left of yesterday. It seems to be designed for very huge and hyperactive installations. In the man page it notes: "In general we do not foresee the need to run xfs_fsr on system partitions such as /, /boot and /usr as in general these will not suffer from fragmentation."
