here is what i get..

Code:
#lsof +L1
 
COMMAND     PID USER   FD   TYPE  DEVICE   SIZE/OFF NLINK   NODE NAME
gstd      21811 root    0w  VREG    85,3 3146831005     0  12684 /opt (/dev/md/dsk/d3)
gstd      21811 root    1w  VREG    85,3 3146831005     0  12684 /opt (/dev/md/dsk/d3)
gstd      21811 root    2w  VREG    85,3 3146831005     0  12684 /opt (/dev/md/dsk/d3)

Any help on fixing this is appreciated.

Is there a symbolic link in your system that points to /opt? Maybe some software application that loads in other directories but links itself to /opt?

In desperation there are likely to be applications in /opt that are not constantly running that could therefore be moved to a different filesystem and then linked to from /opt to make them appear to be still in /opt. e.g. if you had Adobe Acrobat (highly unlikely on a backup server but it will serve for this example) then you could do the following to move Adobe Acrobat to the root file system:
Code:
 
# mv /opt/Adobe /opt_Adobe
# ln -s /opt_Adobe /opt/Adobe

No symbolic liink pointing to /opt ..

No I'm suggesting you move something out of /opt to free up some space and then use a symbolic link to make appear to be still in /opt.

Are we sure that some log file isn't leaking or ran crazy and caused this, or perhaps some temp file or what not?

What does du display of the /opt directory? You can do it at a directory level and if you know certain directories should not be that large then you can narrow the problem down, or are you really just out of space on that volume due to having too much installed in /opt?

if there is a big difference between the output of du and df, there are
probably open files (by a running process), that are deleted or moved.
you can find them, as already reported, with
Code:
lsof -a +L1

or something like this:
Code:
find /proc/ -type f -links 0 -exec ls -l {} \;

should have a similar effect
(find(1) - find files (man pages section 1: User Commands) - Sun Microsystems)

a reboot would probably be the easiest solution.
