Sorry to be contrary here, but I have seen the problem where pulling a
drive causes the device sub-system to freak out and keep trying to
communicate with the device instead of just giving up and reporting an
error.  However, I haven't seen it in the last 5 or more years.  It may
still be an issue, but I haven't seen it.

I will say that at the time I was testing the software RAID I also found
several hardware RAID controllers that behaved exactly the same way in the
same testing...

But, we also have an insanely low disc failure rate on our servers.
With the exception of a recent "bad batch" that was detected before they
event went into production.  I think we've had less than one drive failure
per year on our own servers.  Currently, that involves something around 150
to 200 drives in production, just counting our own servers.  So, the chance
to test the software raid on real-life failures is quite infrequent.

Some of our clients have better luck than others with their own hardware.

Thanks,
Sean
