Deleting a 28gb log file has no impact on disk usage, can someone explain why?

Hi,

Could someone explain the following, I've never understood how deleting a 28gb log file would not reduce the disk usage on the filesystem?

Thanks

Andrew

Code:

[root@linuxcp20051 vhosts]# df
Filesystem           1K-blocks      Used Available Use% Mounted on
/dev/cciss/c0d0p1    139074672  86111216  45898876  66% /

[root@linuxcp20051 vhosts]# du -sh /home/feed.log
28G     /home/feed.log

[root@linuxcp20051 vhosts]# rm -f /home/feed.log

[root@linuxcp20051 vhosts]# df

If the feed.log file is still opened by another program, the inode for that program won't be removed until after that program closes the program.

Or could there be a hard link to feed.log? Not sure how you'd search for that
