Just thought I would let you all know that I followed what Alex suggested along
with what many of you pointed out and it worked! Here are the steps I followed:
1. Break root drive mirror
2. zpool export filesystem
3. run the command to start MPIOX and reboot the machine
4. zpool import filesystem
I'm just wondering what some of you might do with your systems.

I would love to go back to using shuttles.
Actually, my ideal setup would be:
Shuttle XPC w/ 2x PCI-e x8 or x16 lanes
2x PCI-e eSATA cards (each with 4 eSATA port multiplier ports)
then I could chain up to 8 enclosures off a single small, nearly silent host
machine.
8 enclosures x 5 drives = 40
Holy crap! That sounds cool. Firmware-based-VPN connectivity!

Yeah, I'm looking at using 10 disks or 16 disks (depending on which

Would anyone on the list not recommend this setup? I could li

I actually have a related motherboard, chassis, dual power-supplies
and 12x400 gig drives already up on ebay too. If I recall Areca cards
are supported in OpenSolaris...

except in my experience it is piss poor slow... but yes it is another
option that is -basically- built on standards (i say that only because
it's not really a traditional filesystem concept)

1) Is a hardware-based RAID behind the scenes needed? Can ZFS safely
be considered a replacement for that? I assume that anything below the
filesystem level in regards to redundancy could be an added bonus, but
is it necessary at all?
2) I am looking into building a 10-drive system using 750GB or
Would this be the same as failing a drive on purpose to remove it?
I was under the impression that was supported, but I wasn't sure if
shrinking a ZFS pool would work though.

what is the technical difference between forcing a removal and an
actual failure?
isn't it the same process? except one is manually triggered? i would
assume the same resilvering process happens when a usable drive is put
back in...

I've been looking at it for the past few days. I am looking for eSATA
support options - more details below.
Only 2 devices on the list show support for eSATA, both are
for a conversion from RAIDZ
to RAIDZ2, or vice-versa then, correct?

Mike,
I think you are missing the point. What we are talking about is
removing a drive from a zpool, that is, reducing the zpool's total
