yeah i am on gigabit, but the clients are things like an xbox which is
only 10/100, etc. right now the setup works fine. i'm thinking the new
CIFS implementation should make it run even cleaner too.

Yes, that looks pretty good mike. There are a few limitations to that as you
add the 2nd raidz2 set, but nothing major. When you add the extra disks, your
original data will still be stored on the first set of disks, if you've any
free space left on those you'll then get some data stored acros

Yeah I got the install option when I installed snv_94 but wound up not
having enough disks to use it.

It looks like this will be the way I do it:
initially:
zpool create mypool raidz2 disk0 disk1 disk2 disk3 disk4 disk5 disk6 disk7
when I need more space and buy 8 more disks:
zpool add mypool raidz2 disk8 disk9 disk10 disk11 disk12 disk13 disk14 disk15
Correct?

If you use a ZFS mirrored root, you just replace a drive when it

This is incorrect.
Much larger zpools built out of striped redundant vdevs (mirror, raidz1,
raidz2) are recommended and also work well.
raidz1 or raidz2 vdevs of more than a single-digit nu

Nope. That's exactly what you *CAN* do.
So say today you only really need 6TB usable, you could go buy 8 of your
1TB disks,

Lets get the terminology right first.
You can have more than one zPool.
Each zPool can have many filesystems which all share *ALL* the space in
the pool.
Each zPool can get it's space from one or more vDevs.

No that isn't correct.
One or move vdevs create a pool. Each vdev in a pool can be a different
type, eg a mix or mirror, raidz, raidz2.
There is no such thing as zdev.

Oh sorry - for boot I don't care if it's redundant or anything.
Worst case the drive fails, I replace it and reinstall, and just re-mount the

I hear everyone's concerns about multiple parity disks.
Are there any benchmarks or numbers showing the performance difference using a
15 disk raidz2 zpool? I am fine sacrificing some performance but obviously
don't want to make the machine crawl.
It sounds like I could go with 15 disks evenly

Hey Mike,
First of all, I'd strongly suggest going for raidz2 instead of raidz. Dual
parity protection is something I'd strongly recommended over single parity
protection.
You also don't mention your boot pool. You can't boot from a raid pool, so you
need to put one disk aside for booting fr

no. You can have many vdevs in one pool. for example you can have a

Question #1:
I've seen 5-6 disk zpools are the most recommended setup.
In traditional RAID terms, I would like to do RAID5 + hot spare (13 disks
usable) out of the 15 disks (like raidz2 I suppose). What would make the most
sense to setup 15 disks with ~ 13 disks of usable space? This is for a h
