Can somebody explain this? du & ls showing different sizes
Hi
I just came across this issue on my server at home which complained
about the lack of space which I knew was wrong. It was supposed to
have atleast 3.5 gig free. On investigating I found that there a few
lines showing the following behaviour.
Running du -h tells that the file occupies 512M but ls -l tells that
the file is a lot smaller. Also I am sure the the cluster size is not
512M (or am I wrong there?).
I have provided the relevant information from fstab, du, ls and uname
and if more info is needed, I can provide that too. But is there a
solution to this problem?
