With one exception: |
| 7 |
xfs_fsr ("filesystem reorganizer for XFS") which is hidden (on most |
| 8 |
distros) in the "xfsdump"-package. |
| 9 |
|
| 10 |
It is a tool written by the xfs-developers, to defrag xfs-partitions. |
| 11 |
Most importantly it works (only) on mounted partitions! |
| 12 |
|
| 13 |
It can be run from cron, to walk all your xfs-partitions at night and |
| 14 |
continue where it left of yesterday. |
| 15 |
It seems to be designed for very huge and hyperactive installations. |
| 16 |
|
| 17 |
In the man page it notes: "In general we do not foresee the need to run |
| 18 |
xfs_fsr on system partitions such as /, /boot and /usr as in general |
| 19 |
these will not suffer from fragmentation." |
