Thanks for your idea. That would be useful if we had the extra space. After
playing with a test zpool for a bit, I found that this also works, but you have
to make the pool unavailable for a while. I'm just posting it in case it helps
someone else.

Hi All,
Thanks for the recent info on my controller problems. So now I'm taking a
different approach but had a more basic question.
I have:
2x150GB SATA ii disks
2x500GB SATA ii disks
Is it possible/recommended to have something like a pool of two raidz pools.
This will hopefully maximize

This will hopefully maximize my storage space compared to mirrors, and still
give me self healing yes?
You can't create a RAID-Z out of two disks. You either

Hey Adam,
My first posting contained my use-cases, but I'd say that video
recording/serving will dominate the disk utilization - thats why I'm
pushing for 4 striped sets of RAIDZ2 - I think that it would be all

It sounds good, that way, but (in theory), you'll see random
Nit: small, random read I/O may suffer. Large random read or any random
write workloads should be ok.
Given that video-serving is all sequential-read, is it correct that
that raidz2, specifically 4(4+2), would be just fine?
For 24 data disks there are enough combinations that it is not

Probably a 64 bit dual core with 4GB of (ECC) RAM would be a good

Agreed.

I will go with a mirror. You need at least 500GB in parity anyway
(since you want to survive any disk failure). That means the maximum
you can get out of this setup is 800GB. With a mirror,
I've been doing a lot of reading about ZFS lately, and I'm quite enamored of
