You aren't in '/orc_tmp' when you're doing the 'lsof' are you?

Hi,
Make sure u r not in the current directory path.From root kill that processes forcely.
Use fuser -v which will identitfy and displays the PIDs of processes using the specified files or sockets.
Normally if ur not able to kill some proccesses becaz the processes may be dependent on other processes.so try to find the dependent processes files using fuser.And then try to kill it.
Make sure that u unmount the directories which are required by the processes if u had manually mounted.

Regds,
Palani

Hello Hangyu

You just grep the process id by

ps -ef | grep process_name

and then use

kill -9 Pid.

it will work,if the processes are not Zombie.

cd /
fuser -ku /orc_tmp
fuser -ku /dev/device
or
fuser -k -m /dev/device

kill -9 process_id (as always)
