Do you have logfiles on the root filesystem? Try running find looking for large files
that were recently modified

Code:
find / -mtime+3 -type f -size +10000 -exec ls -l {} \;

Nothing under / that stands out.
I run the du -ak * | sort -nr | more command from /home/oracle and all I get is about 140 MB used space. The / fs is 8 GB. when I run that command from / I get a ton of /proc output. Could there be anything like a process holding onto something in there?

Hi,
You have to check the filesystem hosted path and maximum used space in %
using the below command

df -k . | sort +4rn
The above command will listout the maximum used path and filesystem

Then you have check the maximum used filesystem path and check which file used more space in the directory using below command df -k . | sort +4rn

Then you have to ziped the maximum size file if its not current active processed file.



Thanks

I figured it out.

Apparently some Oracle dbf files were created under a new directory that was one level below a mount point:

ieSmilie
/u01/arc/server1
/u01/arc/server2

where server1 is it's own mounted filesystem so they created a directory called server2 but it's not mounted so it created it under /.

This slowly filled up / as data was written to the db.

My du -ak * | sort -nr command eventually led to the discovery, I just needed to sift through all of the output to find it.

Thanks to all who assisted.
