bdf display result delay?

[Jun Zhang_4]

10 minutes ago, /usr is 100% full, I then found the big log file (~700M) and deleted it. Now,
bdf still show it's 100% full. Why?

Hi Jun,

The file is still open.

if you have lsof you can try to find the process which keeps the file open.

Hope this helps,

Probably because the log file was in use when you deleted it.

Find the process that was using the log file (Use "fuser" command) and kill the process.

Thanks

Which file did you delete?

Most probable reason is that the file was being used when you deleted it. And the process that was using file has not released the space.

Just do touch /usr/file_you_deleted.

Now do
fuser -u /usr/file_to_be_deleted.

Check which process is using it.

You can also use lsof tool for this.

Once process closes the file, you can delete the file and space will be reclaimed.

fuser -cu followed by the process related to the log file. Probably when you deleted the file was in "open" state. fuser command will show you the PID. Killing this process would release the space.
