Re: Filesystem busy for umount

Most of the time, "fuser -c /filesystem" will work.

One situation where it will NOT tell you anything is when you try to umount
a filesystem that has another filesystem mounted inside it.

Example:

/dev/hd10opt 1048576 440424 58% 18764 16% /opt
/dev/Oabc 1048576 750084 29% 1315 1% /opt/abc

If you try to umount /opt, it will show up as busy, but fuser will not
report a pid.

I need to determine what is preventing
me from unmounting a filesystem -
it is saying it is 'busy'.

I need this to do microcode updates which are prereq
for the AIX 5.3 upgrade.

Is there a 5.1 command to tell me who is using this fs ?
