Try odmget on the Cuat or CvDv tables I believe they are and then delete
the entry for this filesystem in there all together then delete the entry
in the "/etc/filesystems", but becareful you should backup these tables
first. After you force the unmount from removing it from the ODM tables run
"mount" to make sure it's gone. I believe at that point you won't see that
filesystem anymore with an "lsfs" command anymore. Anywhooo. To prevent
this sort of thing from happening in the future always run an "fsdb" on a
logical volume before mounting it to a filesystem, and type in 0440000 to
make sure your magic number of that partition isn't corrupted.

Hello,

see commands for explanation (aix 5.1 ML03):

# lsfs /stage_bdm
Name Nodename Mount Pt VFS Size Options
Auto Accounting
/dev/stagebdm -- /stage_bdm jfs 10747904
-- yes no
# umount /dev/stagebdm
umount: 0506-349 Cannot unmount /dev/stagebdm: The requested resource is
busy.
# umount /stage_bdm
umount: 0506-349 Cannot unmount /dev/stagebdm: The requested resource is
busy.
# fuser -c /dev/stagebdm ; fuser -c /stage_bdm
/dev/stagebdm:
/stage_bdm:
I get the same (no) response from fuser with -d , -cx -f
I could not find lsof for 5.1

<SNIP>

Any hints?
