In nilfs, a background garbage colletor detects unused disk blocks and
make them reusable. The disk space is reclaimed per ``segment''.
Try lssu command. It will show you the usage state of the partition like:
SEGNUM DATE TIME STAT NBLOCKS
2 2009-06-09 00:51:03 -d- 2048
3 2009-06-09 00:51:03 -d- 2048
4 2009-06-09 00:51:03 -d- 2048
5 2009-06-09 00:51:03 -d- 2048
6 2009-06-09 00:51:03 -d- 2048
7 2009-06-09 00:51:03 -d- 2048
8 2009-06-09 00:51:03 -d- 2048
9 2009-06-09 00:51:03 -d- 2048
...
After 1 hour you have made a change on the partition, the garbage
collector will start. The lssu output above will change with time.
