    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 *** 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!
