Can not umount file system because its busy.

[John Goetz]

This is a Oracle file system and nothing is running on it. Tried ps and fuser and it comes back with nothing. Any other commands worth trying?

Hi John:

Try running 'fuser' using the disk device file hosting the filesystem instead of the mount point:

# fuser -ku /dev/dsk/cXtYdZ

Shalom John,

fuser -cu /filesystem

to see what proceses are open.

fuser -cuk /filesystem

to make those processes go away.

Make sure one of those processes is not your root login session.

Get Process ID information as,

# fuser -cu

and kill them.

Or kill them as,

# fuser -kuc

Try umount operation now!

Hello,

Have you stopped all running oracle processes ?
Also, # fuser -ku will kill all the running process on

Dear,

1 Make sure the database & listner is shutdown

2 do a #ps -ef to ensure that no process uses the f/s

3 may do a #fuser -ck

With Regards,

Siva.

Hi,

Since you say you already tried with ps and fuser, maybe "lsof" can report something.
Is it possible that you have another filesystem mounted under a subdirectory of your oracle filesystem? ( don't have a machine to test, and don't remember if in such case you will see something on the output of ps or fuser ). I'm not sure if this will help.

Hi John


especially use

# lsof -bw +L1 | grep your-lvol

to see if there are deleted, still-in-use files.

Hi!

If any other commands returns nothing, comment filesystem in /etc/fstab and restart system.
