Were any processes using this when you unmounted it?
By the way, is this HP-UX? HP doesn't normally use disks like sda1. This appears to be linux of some variety.

what does "fuser -m /dev/sda1" show?
In linux, it is mostly related to the Device mapper. If you disabled disable dm-mod/dm-mirror and restart this should be OK.

Ok dbf is one thing , but what does the
mount command return ?
Just type mount
1) Make sure you are not with any prompt
or cursor on /Ora1 , or left another session
there. Check child processes su - or rlogins
that arrived on this /Ora1. Exit and kill
all sessions (see who -r).
Login in via the console, so you know
it is only you loggin in.
2) If you are sure there is nothing on /Ora1
and fuser -cu shows nothing then you need
to install lsof , which will give more detail
of lost filehandles, network processes, memory stuff etc. etc. You may have something
in memory not updating the mount table or
FOR INFO on lsof goto:

Maybe your filesystem is shared by nfs?
This will keep your fs busy but wil NOT show in fuser/lsof as nfsd is a linux kernel daemon.
$ exportfs -u "your-fs"
and umount again.

There might be mount points below /Ora1 (most probably NFS) that are in use. Use the mount command to search for "/Ora1" entries and and if the mount points are NFS of AutoFS, then turn off the automounter before retrying the mount.
Don't forget to turn on the automounter once the mount command is successful.

try the following:
dmsetup remove_all; sleep 10; mount /dev/sda1 /Ora1
