Full root FS
I have a HP-UX 11.0 box with root file system 150MB.
Today I see it is 98% full and I can't find nothing wrong. All FS are mounted, no large files found using "du". I try lsof but I still
can not find the process that keep this large file open, I think.
Help!

Re: Full root FS
Try this find command; you are less likely to miss a file than with du:
find / -xdev -size +2000
There should be very few files > 2000 blks in /

Re: Full root FS
Check for files that don't belong in /dev . If you have done something lika a 'tar' but mis-spelled "/dev/rmt/0m", for instance, then you didn't reference the device file but rather created a file and therefore added substantial disk space.

Re: Full root FS
/var/adm/crash
Look for everything
/var/adm
look for large acct files
/var/mail
look for big mail files...
/var/spool
look for dead print jobs that are huge!
check /var/dt for unused configurations, old error logs, etc...
check the dot files under /, especially if your running netscape! The cache directory defaults to 10MB. Also, check the /.dt directory. If there are problems, logs and junk will be there.
The best tool to use is "/usr/bin/du".
I.E.
> cd /
> du -sk *
This will show the use of all the directories!
Regards,
Shannon

Re: Full root FS
I've thought of one other place your space may be hiding - beneath a mountpoint. You may need to unmount a filesystem (e.g. /home) and then do an ls /home to see if files and directories appear.
Just one more idea, Clay

Hi again again A. Clay Stephenson,
Good idea, If the problem doesn't go away after reboot,
I have to check it!
Thanks all, but I still need help.
If you need some more information just let me know!!!

Re: Full root FS
The normal way to cure this is find the process using something lik efuser, or reboot the system and see if that frees up the space.
If it does, monitor var closely and try to discover which process is writing to it.

Re: Full root FS
Check the /dev directory. Sometime a failed backup is dumped there. look for a non character file.
du -ka /dev |sort -rn|more will list the large file in ascending order.
