Can this be done?
I currently have a 7x1.5tb raidz1.
I want to add "phase 2" which is another 7x1.5tb raidz1
Can I add the second phase to the first phase and basically have two
raid5''s striped (in raid terms?)
Yes, I probably should upgrade the zpool format too. Currently running
snv_104. Also should upgrade to 110.
If that is possible, would anyone happen to have the simple command

ZFS configuration suggestion with 24 drives
Replacing my current media server with another larger capacity media server. Also switching over to solaris/zfs.
Anyhow we have 24 drive capacity. These are for large sequential access (large media files) used by no more than 3 or 5 users at a time. I''m inquiring as to what the best configuration for this is for vdevs. I''m considering the following configurations

ZFS Newbie question
I?ve spend a few hours reading through the forums and wiki and honestly my head is spinning. I have been trying to study up on either buying or building a box that would allow me to add drives of varying sizes/speeds/brands (adding more later etc) and still be able to use the full space of drives (minus parity? [not sure if I got the terminology right]) with redundancy. I have found the ?all in

ZFS RAID-Z2 degraded vs RAID-Z1
Had an idea, could someone please tell me why it''s wrong? (I feel like it has to be).
A RaidZ-2 pool with one missing disk offers the same failure resilience as a healthy RaidZ1 pool (no data loss when one disk fails). I had initially wanted to do single parity raidz pool (5disk), but after a recent scare decided raidz2 was the way to go. With the help of a sparse file

RAIDZ v. RAIDZ1
So, I took four 1.5TB drives and made RAIDZ, RAIDZ1 and RAIDZ2 pools. The sizes for the pools were 5.3TB, 4.0TB, and 2.67TB respectively. The man page for RAIDZ states that "The raidz vdev type is an alias for raidz1." So why was there a difference between the sizes for RAIDZ and RAIDZ1? Shouldn''t the size be the same for "zpool create raidz ..." and "zpool

RAID10
Hi All,
I am looking at ZFS and I get that they call it RAIDZ which is similar to RAID 5, but what about RAID 10? Isn''t a RAID 10 setup better for data protection?
So if I have 8 x 1.5tb drives, wouldn''t I:
- mirror drive 1 and 5
- mirror drive 2 and 6
- mirror drive 3 and 7
- mirror drive 4 and 8
Then stripe 1,2,3,4
Then stripe 5,6,7,8
How does one do this with ZFS?

Convert raidz
Hi
Is it possible to convert live 3 disks zpool from raidz to raidz2
And is it possible to add 1 new disk to raidz configuration without backups and recreating zpool from cratch.
Thanks

Optimal strategy (add or replace disks) to build a cheap and raidz?
Hello,
i have an 8 port sata-controller and i don''t want to spend the money for 8 x 750 GB Sata Disks
right now. I''m thinking about an optimal way of building a growing raidz-pool without loosing
any data.
As far as i know there are two ways to achieve this:
- Adding 750 GB Disks from time to time. But this would lead to multiple groups with multiple
redundancy/parity disks. I

btrfs wishlist
Hi all
Having managed ZFS for about two years, I want to post a wishlist.
INCLUDED IN ZFS
- Mirror existing single-drive filesystem, as in ''zfs attach''
- RAIDz-stuff - single and hopefully multiple-parity RAID configuration with block-level checksumming
- Background scrub/fsck
- Pool-like management with multiple RAIDs/mirrors (VDEVs)
- Autogrow as in ZFS autoexpand

Question about multiple RAIDZ vdevs using slices on the same disk
Hi all :)
I''ve been wanting to make the switch from XFS over RAID5 to ZFS/RAIDZ2 for some time now, ever since I read about ZFS the first time. Absolutely amazing beast!
I''ve built my own little hobby server at home and have a boatload of disks in different sizes that I''ve been using together to build a RAID5 array on Linux using mdadm in two layers; first layer is

Large Drives
The time has come to expand my OpenSolaris NAS.
Right now I have 6 1TB Samsung Spinpoints in a Raidz2 configuration. I also have a mirrored root pool.
The Raidz2 configuration should be for my most critical data - but right now it is holding everything so I need to add some more pools and move some data around.
To start I need a vdev I will call "temp" that acts as a networked bit

RAIDZ(2) expansion?
I skimmed the archives and found a thread from July earlier this year
about RAIDZ expansion. Not adding more RAIDZ stripes to a pool, but
adding more drives to the stripe itself. I''m wondering if an RFE has
been submitted for this and if any progress has been made, or is
expected? I find myself out of space on my current RAID5 setup and
would love to flip over to a ZFS raidz2 solution

RAID-Z/mirror hybrid allocator
Hi, I''m referring to;
http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6977913
It should be in Solaris 11 Express, has anyone tried this? How this is supposed to work? Any documentation available?

zfs raidz questions
Hi there,
i''m building a small NAS with 5x1TB Disks. The disks contains at the moment some data, ntfs as the fs and aren''t a raid.
Now my im wondering if its possible to add the parity later. So that i add step by step one disk to the pool. And when i add the last disk, i enable the parity.
(i have only one another 1 tb disk to backup the files)
Thank you for you replies and

Rule of Thumb for zfs server sizing with (192) 500 GB SATA disks?
I''m trying to get maybe 200 MB/sec over NFS for large movie files (need large capacity to hold all of them). Are there any rules of thumb on how much RAM is needed to handle this (probably RAIDZ for all the disks) with zfs, and how large a server should be used? The throughput required is not so large, so I am thinking an X4100 M2 or X4150 should be plenty.

Mixing RAIDZ and RAIDZ2 zvols in the same zpool
I have a customer who has implemented the following layout: As you can
see, he has mostly raidz zvols but has one raidz2 in the same zpool.
What are the implications here? Is this a bad thing to do? Please
elaborate.
Thanks,

Data distribution not even between vdevs
Hi list,
My zfs write performance is poor and need your help.
I create zpool with 2 raidz1. When the space is to be used up, I add 2
another raidz1 to extend the zpool.
After some days, the zpool is almost full, I remove some old data.
But now, as show below, the first 2 raidz1 vdev usage is about 78% and the
last 2 raidz1 vdev usage is about 93%.
I have line in /etc/system

6 disk raidz2 or 3 stripe 2 way mirror
I''m playing around with ZFS and want to figure out the best use of my 6x
300GB SATA drives. The purpose of the drives is to store all of my data at
home (video, photos, music, etc). I''m debating between:
6x 300GB disks in a single raidz2 pool
--or--
2x (3x 300GB disks in a pool) mirrored
I''ve read up a lot on ZFS, but I can''t really figure out which is

cannot replace c10t0d0 with c10t0d0: device is too small
In 2007 I bought 6 WD1600JS 160GB sata disks and used 4 to create a raidz storage pool and then shelved the other two for spares. One of the disks failed last night so I shut down the server and replaced it with a spare. When I tried to zpool replace the disk I get:
zpool replace tank c10t0d0
cannot replace c10t0d0 with c10t0d0: device is too small
