I am running AIX 3 4.

When I do a df I get:

This shows the /tmp is 100% used. I have looked in every /tmp directory I can find (by using 'find') and there are no big files filling up the space. How do I find the files that are filling up the space? I have already deleted all the 'core' and smit.log files. This happened a week ago and I cannot free up the space. Can anyone please help?

Thanks!

This will give you a full listing of directories/files in /tmp, in the order of the space they occupy. Then you can check out the individual files/directories and purge.

The only files I can find of any size are in the /tmp/vgdata/rootvg:

# cd vgdata
# ls
rootvg
# ls -l rootvg
total 112
-rw-r--r-- 1 root sys 336 Jul 08 23:32 hd2.map

-rw-r--r-- 1 root sys 156 Jul 08 23:33 lv05.map
-rw-r--r-- 1 root sys 744 Jul 08 23:33 lv06.map

I'm not familier with .map files - can I safely delete these?

Steve

You need to use a program like fuser or lsof on /tmp. Files do not always have names. If a process has a file open, the space will not be released just because you unlink the only file name it has.

Yes, it is possible that a process is stuck in a loop and writing continuously to a log or a debug file. Can you check 'top' and see if any process is taking up an unusual amount of CPU %age?

There doesn't seem to be a 'top' command on this system.

Steve

Well, use whatever tools AIX has to see processes. If this has been going on for a week, the process will be that old. Can you reboot? That will free the space.
