Problem unmounting a NFS filesystem - AIX

Hello everybody, I'm having a 'little' problem while unmounting a NFS filesystem. Some days ago I change the IP address of a lab machine that was exporting a /depot filesystem. This /depot filesystem was mounted in one of my servers. Today when I realized that I tried to unmount the /mnt (directory where the /depot of my lab machine was mounted) and I received the following message: bash-2.04# unmount /mnt umount: 1831-015 16 error while unmounting lab:/depot - The requested resource is busy.

    Default Problem unmounting a NFS filesystem

    Hello everybody,
    I'm having a 'little' problem while unmounting a NFS filesystem.
    Some days ago I change the IP address of a lab machine that was
    exporting a /depot filesystem. This /depot filesystem was mounted in
    one of my servers. Today when I realized that I tried to unmount the
    /mnt (directory where the /depot of my lab machine was mounted) and I
    received the following message:
    bash-2.04# unmount /mnt
    umount: 1831-015 16 error while unmounting lab:/depot -
    The requested resource is busy.
    I also tried to use the -f flag:
    bash-2.04# unmount -f /mnt
    umount: 1831-015 16 error while unmounting lab:/depot -
    The requested resource is busy.

    Issuing the comand fuser, I had no answer:
    bash-2.04# fuser /mnt
    /mnt: ^C

    Issuing the command lsof, I didn't find anything:
    bash-2.04# ./lsof -X |grep mnt
    lsof: WARNING: compiled for AIX version 4.3.2.0; this is 4.3.3.0.

    Indicating the /mnt directory I received the following:
    bash-2.04# ./lsof -X /mnt
    lsof: WARNING: can't stat() unknown file system /mnt
    Output information may be incomplete.
    assuming "dev=0x8000000f" from mount table
    lsof: WARNING: compiled for AIX version 4.3.2.0; this is 4.3.3.0.

    So, What am I doing wrong? Can any of you give me a hint?

    Thanks in advance,

    Jackson

    Default Re: Problem unmounting a NFS filesystem

    I had similiar problem when being in the NFS fileystem I started some
    background program (some daemon).
    After daemon was killed and started being in the othe PATH, NFS fs was able
    to umount...

    try:

    lsof |grep mnt
    or lsof -a|grep mnt

    regards,
    Y.
