Can you post the output from:

Code:

df -k

I am concerned that you may be confusing the output of "ls -l" of the /export/home directory with matters related to disc space usage of /export/home directory.

If you have not done so already, it is time to consider how to restore the damaged areas from backup. It would be prudent to find out what has filled the /export/home directory and to repair that problem first.


As for moving everything back, this line is worrying depending on what was in the target tree to start with (and whether that tree existed):
It would help to see any non-comment lines in the file /etc/oratab so we know the names of the oracle instances and can relate them to the directory trees.

Unless you have Oracle database segments or Oracle temporary files in the Oracle appplication tree the most likely files to fill this tree are: Oracle listener logs, Oracle audit logs and Oracle trace logs.

Have you tried a blunt search of the filesystem looking for Oracle log files which grow in size or sheer number of files?

This command might reveal your issue with /export/home : (Adjust -mtime <days> if this is a recent install).

Code:

find /export/home/ -mount -mtime -60 -exec ls -lad '{}' \;
