Hi, Everybody.
I have some problems using fuser.
I want to kill processes accessing a certain block file, eg /dev/sda6 and decided to use fuser.
But some programs are not mapped and killed.
I ran openoffice word processor, gedit, kwrite and opened some text and doc files on /dev/sda6.
Then ran the following command on the terminal.

[root@localhost ~]# fuser -mv /dev/sda6
USER PID ACCESS COMMAND
/dev/sda6: root 3587 F.... swriter.bin
[root@localhost ~]# fuser -km /dev/sda6
/dev/sda6: 3587

As you see, only word processor was mapped and killed.
Nothing happened about gedit and kwrite, even though I had root privilege
I don't know how to solve this problem and have some other problems.
My target is to close all applications accessed /dev/sda6, saving their opened files.
Do you have any suggestion?
Please help me out.
Best regards to you...

Are you sure the files actually were open at that time? Because at least some (text) editors work so that they don't work on the actual file, but rather work on it's copy, and when you save, the changes are then written to the file. That way the original file does not need to be open all the time, potentially causing some trouble (and that's why the editors, or some of them at least, can warn you if the original file was edited by some other process). I could be wrong, but check it to make sure.

The copy would of course still exist on the same directory (or so I think), but it's also possible that the contents are kept in a buffer and the file - be it the original file or copy - is only open when it's being read or written. Namely just when you open or save, or if the app automatically saves changes at intervals to keep it "safe" - and these "autosaves" it probably puts into the cache file rather than the original. Usually these "cache files" have the same filename as the original, but a tilde ~ added to it.
