if a vdev fails you loose the pool.
if you go with raidz1 and 2 of the RIGHT drives fail (2 in the same vdev)
your pool is lost.

the better option.

At the end of the day, it TOTALLY depends on your needs. raidz may be the

i don't think it's the same at all.
I think it's about the same as filling a radiator in a car with oatmeal to
make it stop leaking.

yes, but it stripes across the vdevs, and when it needs to read data back,
it will absolutely be limited.

you can't without forcing...and even if you do, it's not a good idea.
if you do your pool will have the lowest redundancy/speed of the worst

sooo if you add a single drive to a raidz vdev, your entire pool loses it's

Let me explain what i have and you decide if it's what you're looking for.
I run a home NAS based on ZFS (due to hardware issues i am using FreeBSD 7.2
as my os but all the data is on ZFS)
This system has multiple uses. I have about 10 users and 4 HTPC's connected
via gigabit. I have ZFS filesyst
I've been running ZFS under FreeBSD which is experimental, and i've had
nothing but great luckso i guess it depeneds on a number of things. I
went with FreeBSD because the hardware i had wasn't supported in
solarisi expected problems but honestly, it's been rock solidit's
survived all

if you are talking about NFS, this is due to how ZFS file systems work.
When you share a ZFS filesystem via NFS it will share everything IN that
filesystem but if you have 2 filesystems, it will only share that second
fs's mount point.
what i mean is, if you have something like pool/filesystem

i had something similar happen to me when i switched to ZFS but it turned
out to be an error with cpio and the mkv format...i'm not sure exactly why
but whenever i tried to backup mkv files with cpio onto ZFS it would give me
corrupted files.

dude, i just explained it =)
ok...let me see if i can do better...
if you have a file that's 1 gb , in zfs you have those blocks added. on a
normal filesystem when you edit the file or add to it, it will erase the old
file and add a new one over it (more or less).
on zfs, you have the blocks ad
it's pretty simple, if i understand it correctly. When you add some blocks

then take a snapshot
(snapshot of x)
the disk has the space of the x's and the snapshot does't take up any space
yet
then you add more to the drive
and maybe take another snapshot

i'm not sure if it applies to your situation, but when i FIRST starting
using ZFS on freebsd, i noticed a similar error, where a filesystem would be
totally empty and still show 14 GB space...it's weird but i remember this
because i had quotas set (freebsd didn't have refquotas at the time). We

i think you can add different types of vdevs but doesn't it make you use -f?
i thought it was "not a good idea"

unfortunately this is not possible right now. The only way to expand raidz
is to add another raidz vdev or replace all the disks with larger ones...

Why not just do simple mirrored vdevs? or use cheaper 1tb drives for the
second vdev?
I don't knowit's up to you...To me the benefits of ZFS far outweigh the
limitations. Also, in my opinion, when you are expanding your storage, it's
a good idea to add it in chunks like this...adding a 4 drive
While it is true that you can not add a single device to a raidz vdev, you
can easily add more vdevs, and this is by far the best way to grow because
each vdev adds much speed to the array. Raidz is more advanced than raid5,
the fact that your card doesn't do the raid calculations is not a
