Hi Todd,
Having finally gotten the time to read through this entire thread, I think Ralf
said it best. ZFS can provide data integrity, but you're reliant on hardware
and drivers for data availability.
In this case either your SATA controller, or the drivers for it don't cope at

I plan on fiddling around with this failmode property in a few hours. I'll be

I'll let you know what I find out.

While responding to halstead's post (see below), I had to restart several times

not, but I just wanted to put it out there anyway.

Okay, so your ACHI hardware is not using an ACHI driver in solaris. A crash
when pulling a cable is still not great, but it is understandable because that
driver is old and bad and doesn't support hot swapping at all.

You're correct, it doesn't. Furthermore, to the best of

Hmmm. Alright, but supporting hot-swap isn't the issue, is it? I mean, like I

I'm pretty sure pci-ide doesn't support hot-swap. I believe you need ahci.

Hmm... You know, that's a good question. I'm not sure if those SATA II ports
support hot swap or not. The motherboard is fairly new, but taking a look at
the specifications provided by Gigabyte

PS. Does your system definitely support SATA hot swap? Could you for example
test it under windows to see if it runs fine there?
I suspect this is a Solaris driver problem, but it would be good to have
confirmation that the hardware handles this fine.

Howdy yall,
Earlier this month I downloaded and installed the latest copy of OpenSolaris
(2008.05) so that I could test out some of the newer features I've heard so
much about, primarily ZFS.
My goal was to replace our aging linux-based (SuSE 10.1) file and media server
