can't kill process

Mohd Rasidi Che Mat — Wed, 29 Oct 2008 01:30:25 GMT

hi all,
i'm unable to kill 2 processes below:
root 24405 1 0 Oct 22 ? 0:00 dd if=/dev/rdsk/c12t0d0 of=/dev/null bs=1024k count=64
root 6917 1 0 Oct 24 ? 0:00 pvremove /dev/rdsk/c12t0d0

I've used 'kill -9' & 'fuser -ku' but failed. any suggestion?

Normally when this happens, it means that the process is stuck waiting for a system call to come back. My terminology might not be right, if that's the case I'm sure someone else will step in. But it's clear here that it's blocking on I/O on c12t0d0.

If c12t0d0 is dead or has been removed, I don't know what could make the process die besides fixing the disk or rebooting.

Hi,

Below are some other way to kill process
try it :
kill -s SIGKILL 24405
kill -s KILL 24405
kill -s 9 24405
kill -SIGKILL 24405
kill -KILL 24405
kill -9 24405

you can't kill the that PID which has PPID 1. that is init process of system.

either you hav to disable/stop the process that is responsible for this.

>ahsan: you can't kill the that PID which has PPID 1. that is init process of system.

I'm not sure why you are bringing up PPID and init? The two processes in question just happen to have init as a parent but that doesn't have anything to do with it, other than their old parent was able to be killed.
