Re: "df" reports wrong size of filesystem

Hi!

Thank you for your detailed explanations!
So that I understand it correctly, the seizure of the filesystem is
correct. But because Oracle still keeps the files open or has still
some locks on the files/links, "df" show the wrong size. So the next
time, the DB will be restarted, the filesystem-size in "df" is correct?

If I've finally got right. The file was never deleted, the directory
entry (pointer) was deleted.
The inode exists as long as an application has it open whether it has a
directory entry or not.

df always the correct usage, du gives the file sizes associated with
the directory tree. So you can
have an inode in use with no name (because an rm was executed while it
was open).

The application (I assume in this case oracle) needs to be stopped. the
inode associated will
the deleted filename will be closed and the data removed and then the
results of df and du will
coincide.
