Is the /data partition on reiser? Did you enable tailpacking? |
| 17 |
As I don't know what the script you ran actually does, I don't know |
| 18 |
how it handles block suballocation... Tail packing is something that |
| 19 |
can conceivably introduce data fragmentation in place of internal |
| 20 |
fragmentation. |
