a RAID reconstruction so I want to simulate a hardware failure.
How can I do this in Linux without having to physically pull
a drive? These disks are behind a RAID card and run Linux. -ausman
\_ According to the Linux RAID wiki, you might be able to use mdadm
to do this with something like the following:

nightmare of poor IO performance should hopefully be over. Prepare for
another long nightmare of poor hardware reliability!

Just kidding! (I hope)
In any case, this means that cooler was taken out back and shot, and

uptimes.
\_ hardly, My winbox stays up longer.
\_ Nobody cares about uptime anymore brother, that's what web2.0 has
taught us. Everything is "stateless".
\_ You;d think gamers would care more about uptime.

2 questions, on linux when <disk>==hda it always gives me this off
by one report i.e. Records out == records in-1 and says there is an
error. Has anyone else seen this? Second, when trying to repeat this
on bsd, <disk>==rwd0 now, to my surprise, using the install disk and
selecting (S)hell, when I try to dd a 40 gig disk it says "409 records

case, with sata connectors, gig-e ethernet, and lots of
slots for RAM? I also don't want to have to use expensive
double buffered RAM. Can you tell I havne't bought a PC in
years? thanks.

Service Pack 3 installed. I have a valid key that I own (yeah yeah I
actually *bought* a copy, please don't flame me for supporting evil
M$). Is it possible to register the key once, and then duplicate it
for testing purposes? Will Windows or Microsoft detect copies and
disable the rest the copies?

on VMWare isn't really using 80GB, it just uses what it needs.
Will defragment do anything to it?
\_ If you want to speed up disk operation in your VM, it's best to
defragment the disks in your VM, then defragment the disk on your
host machine where the VM files are.

It has crashed 3 or 4 times on me in the last hour, and not on
the same pages either. The new Yahoo! home page also sucks ass.
\_ os x keeps trashing my raid disk: '11 hours to rebuild. have fun
with the kernel IO subsystem running like shit until then".
Worthless piece of shit.
