Re: [cobalt-users] THE GRINDING DRIVE PROBLEM

[Will DeHaan <will@xxxxxxxxxx>]

Jeremy,

Interesting problem, but it's presented to the list a little
simplistically.  Most hard drives make a high pitched screaming noise,
yes, much like attending an Indy race, when they are failing.  

I don't know what you mean by "grinding" however.  A server that does
not have enough memory will start swapping, the hard drive will start
chugging away, server performance will decrease rapidly, and if not
fixed in a few weeks or months time the hard drive will fail.  As
expected.  Get an OS restore CD, buy any brand hard drive, add it to a
server that does not have enough memory, and watch the drive fail as
expected. 

Jeremy, could you telnet to a RaQ that is making this grinding noise and
type the following, then send output back to this list?

cat /etc/build
cat /proc/meminfo
w
df

Please be patient as I don't think the problems you're experiencing are
common problems to other Cobalt users.  

You will make the nice technical support guys take offense by implying
that they haven't been honest with you when no doubt they haven't been
able to obtain a reasonable set of symptoms about your problem(s).  Why
do you double quote "The Grinding Drive Problem"?  A search of
cobalt-users from its inception does not turn up this phrase so I don't
see how you could expect other Cobalt users to be familiar with this
problem.
