Hi Max,
I re-ran the cp command and when it hanged I ran 'ps -el' looked up the cp
command, got it's PID and then ran:
# truss -p PID_of_cp
and it output nothing at all -- i.e. it hanged too -- just showing a flashing
cursor.
The system is still operational as I am typing into the browser.
Before I ran the cp command I did a 'tail -f /var/adm/messages' and there is no
output. I also did a 'tail -f /var/log/syslog' and there is also no output.
If I try 'kill -15 PID_of_cp' and then 'ps -el' cp is still running.
And if I try 'kill -9 PID_of_cp' and then 'ps -el' cp is still running.
What next ?
For what it's worth, here is further output from iostat, the first line looks
interesting, but it appears to be buffered, as it's the same each time I run it
-- possibly the last info from cp before it died??? (see below)
So, any ideas what I can do next? Just going to reboot to kill the hanging cp
-- wow, this is like Windows now :( (attempt to keep humor)
bash-3.2$ iostat -xce 1
