[wplug] kill

[Poyner, Brandon]

That sounds like the process is in an uninterruptible sleep, which is
usually caused by a process waiting on i/o.  You can't use kill to end
such a process.  If you run a ps and grep on the process, look at the
stat field.  If the stat is showing a D then it is in an uninterruptible
sleep (check the ps man page for other STATs).

If that's the issue the drive is most likely going bad or is improperly
connected.  I'd download the diagnostic tool from the drive manufacturer
to be sure.

What can I do if "# kill -9 $pid" doesn't work?
I've been having immense difficulties with a new (to this computer) hard
disk.
The disk is supposed to be just for backups, and is mounted with a
script, the
backups run, and then it's unmounted.

It sometimes works ok, but at other times I try stuff like "ls
/root/backups"
(where it's mounted) and ls freezes. I can't kill the process, and
therefore
can't unmount the drive. It's not just ls either, cp didn't work - and
it just
hangs there. Even tab completion freezes up "cat ~/backups/<tab>"
freezes it.

When I tell the computer to reboot, it doesn't do that either. I get a
new
process called "[shutdown] <defunct>" after the "shutdown -r 0 w"
process.


The partition on /dev/hdb1, formated as reiserfs (my root directory and
RAID 0
are both reiserfs too, no problems with them)
I don't suspect there's anything wrong with the physical drive. It was
in my
parent's computer until they upgraded and had always worked fine.
