df -k not showing total

[MoreFeo]

Hi, we're seeing some strange things in one of our servers (Solaris 9).

df -k shows a 24GB filesystem with 2,7GB used.

Inside this filesystem there are some directories with a lot of files, each one >2GB, that makes more than 30GB used.

Do you know what can make this difference?

# df -k /oracle/SPD

PS: double-checked, and there is no other filesystem under /oracle/SPD that includes these directories

They are probably 'sparse' files. Random link found in Google:

Thanks. that seems to be exactly our case.

We detected a problem because TSM was backing up more than the filesystem's total, now we're going to see how to tell TSM not to "inflate" these files.
