hi, as regards to the above problem, the OS is AIX 5.3

Try:
fuser /dev/oraclelv2
Also, is anything mounted on top of /oradata? You have to unmount that first.

Last resort: Try commenting /oradata out of /etc/fstab (may be /etc/filesystems on AIX) and then reboot.

u were indeed rite, there were filesystems under /oradata
such as /oradata/arclogs
/oradata/backups and so on..
unmounting them did the trick.

Thank u, my mind totally went blank on that one.
