Hello,
I got many responses. Lots of people recommend using
lsof/pfiles, which failed in our environment. One
possible reason is we are using vxfs filesystem and
lsof doesn't recognize it.

Sherman Butler and Casper Dik suggests using:
find /proc -links 0 -type f -ls
It lists all the processes and can't tell which one is
the stale one.
Finally, I restart all the processes using that
filesystem and the disk space is back.:-)
Here I really appreciated the following people
spending time to respond my question.

Original Question ------
I got many responses recommending lsof or fuser.
I am sorry not to clarify my sitution in original
mail.
I don't know who/when the file was deleted and don't
know the filename either. Just because of the weird
space difference, I suspect some log files have been
removed with processes up and running.
I thought the /proc structure should contain the file
node information and am writing a script to go through
all the related process. In the mean time, I am open
to other methods or opinions.:-)
best regards,
zhu

Hello everyone,
One team member removed a big log file without killing
the process, causing disk space un-released from
process.
We are running solaris 9 with volume manager 4.0. Is
there anyway I can find that particular process
without rebooting the whole system?
thanks very much!
