Hi:

One common mistake is to have changed driectories ('cd') into the filesystem that you want to unmount. 'cd' to the root directory and unmount.

It is also possible that some process has a file in use within the filesystem you are trying to unmount. Use:

# fuser -cu /oracle/DEV/sapdata6

...to see files that are in use

# fuser -ku /oracle/DEV/sapdata6

...to kill all processes using files

Regards!

if i use

#fuser -ku /oracle/DEV/sapdata6

it will effect any data

Hi Mukkala ,

1. First check if the filesystem is busy.

# fuser -cu /oracle/DEV/sapdata6

2. If orcle is running needs to stop.
Check with :
# ps -ef | egrep '(pmon|ora)'

3. If u used fuser -ku forcefully , oracle related process will be killed.

4. check with pwd , your current working directory. You should not be seating in the /oracle/DEV/sapdata6 directory.

Hope this will help ,

Cheers,
Raj.

Hi (again):

Begin with finding what processes (by pid) are using the filesystem:

# fuser -cu /oracle/DEV/sapdata6

(see the manpages for 'fuser(1M) for the interpretation of the output).

If possible, gracefully terminate all processes using the filesystem. This is always preferred to drastic kill actions like :

# fuser -ku /oracle/DEV/sapdata6

Regards!

Hi Mukkala ,

Here is your profile :


"I have assigned points to 8 of 60 responses to my questions. "


Try to make it 60 of 60 , by assigning points to all responses , and make your forum profile better and looks good , and get faster response.

Enjoy Foruming,

hth ,
Raj.

That might not have been a very smart thing to do. It appears that the filesystem was in use by an Oracle DB. A better bet would have been to shut down the Oracle DB, rather than indiscriminantly killing processes.

Hopefully your DB will be OK.

[Raj D.]

Hi Mukkala,

Its clear from fuser output that , filesystem is busy and used by , oracle user oradev and devadm.

You need to shutdown oracle. Consult your DBA.

If You want to shutdown oracle:
# /sbin/init.d/oracle stop
(Check for this script)


Hope fully after this you can unmount.

Cheers,
Raj.

[mukkala]

after completing f.s increasing can i start oracel same path

[mukkala]

RAJ/JRF

Thank you very much for immediate response.

[Raj D.]

Yes , you can start the same way , in the same path.

# cd /sbin/init.d/
# ./oracle start

cheers,
Raj.

[mukkala]

thanks
