file system corrupted and chkfsys "Cannot fix"

I upgraded my beta3 to the latest qrtp. It has the same file system
disappear problem I reported before. That is after heavy load of
work, the file system disappears. Somebody told me that the file system
program crashed. Anyway, I reboot the system. Ran win98 scandisk.
Boot back to qrtp. Run ‘chkfsys /’. Well, this time it said it cannot
fix it.

By the way, I don’t have the file “POINT”, “XFTRREMOVE”, etc. These look
like text in some of my files.

Is there anyway to fix the file system? I checked various chkfsys option.
Nothing helps. May be it does mean it “Cannot fix”.

You should be able to run zap (/usr/bin/zap) on the directory
…/cw/rdbms/testsrc.jap and that will allow you to remove it.
After that you will want to run chkfsys after on it to reclaim any lost
blocks. You will lose any of the data that is in that directory,
but the rest of your disk should be intact.

What sort of heavy load were you putting on the filesystem prior to this
happening?

Thanks. It works. I am almost re-install the OS from scratch.

I was running our test suites. It involves compiling, linking and running.
I had this random file system disappearing problem before. Sometime
I can run the whole test suite without any problem. Also, this can
happen randonly whenever I run something heavy like compiling all my
source code (nothing to do with my test suite).
