usr directory is full

Hello,

What can I do in order to avoid /usr directory from explosion? (bdf - more then 90%)

Yali,

On a properly configured HP-UX box, the /usr filesystem should be pretty much static. It should only increase in size if you install patches and/or new products (and not many should new products go in /usr).

If your /usr filesystem is constantly growing then you need to find out what is writing to it and move it somewhere else.

1) try to find/remove any core files

2) du -sk /usr/* | sort -nr | head #?

3) resize fs?

/usr will grow whenever you add additional products and files. The most important thing to do is to locate the big directories, like this:

du -kx /usr | sort -rn | head -20

This will show you where the biggest directories are located. You have to determine if those directories are the correct size or that perhaps (a bad program) has stored a log file there. Otherwise, /usr will have to be expanded in size. 1000 MB is OK for 11.00 and earlier, but very small for 11.11 or higher. At 11.31, 4000 MB is required to keep from overflowing. But this alll depends on what you are installing.

Post a copy of: bdf /usr and the above du command.

These don't seem to match. The du(1) output seems to be around 40 Mb and here it says you have 400 Mb used.

You probably have a unlinked file still open. You'll need to download and use lsof to see which process has it opened.

>I don't sure the attachment is there.

You probably need a .txt suffix. You might as well delete those two "empty" posts.

Using the post Options menu on the right.
