similar to: ZFS for my home RAID? Or Linux Software RAID?

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?

Hi, I hope there''s someone here who can possibly provide some assistance. I''ve had this read problem now for the past 2 months and just can''t get to the bottom of it. I have a home snv_111b server, with a zfs raid pool (4 x Samsung 750GB SATA drives). The motherboard is a ASUS M2N68-CM (4 SATA ports) with an Athlon LE1620 single core CPU and 4GB of RAM. I am using it

HI All, I have a dilemma and I would appreciate advice 1. Get a good size case, mobo, processor, etc and put 8 hard drives it in and RAID them. (yes an 8 port SATA mobo). Running CentOS. or 2. Get an eSATA enclosure that has room for 8 or 10 drives and just connect it to box? I know that RAID is not a full proof backup, but I am looking for a solution to store all of my data, projects, music,

Anyone have any experience with a R510 with the PERC H200/H700 controller with ZFS? My perception is that Dell doesn''t play well with OpenSolaris. Thanks, Geoff

Hello, Has anyone out there been able to qualify the Proliant DL360 G7 for your Solaris/OI/Nexenta environments? Any pros/cons/gotchas (vs. previous generation HP servers) would be greatly appreciated. Thanks in advance! -Anh

My current home fileserver (running Open Solaris 111b and ZFS) has an ASUS M2N-SLI DELUXE motherboard. This has 6 SATA connections, which are currently all in use (mirrored pair of 80GB for system zfs pool, two mirrors of 400GB both in my data pool). I''ve got two more hot-swap drive bays. And I''m getting up towards 90% full on the data pool. So, it''s time to expand,

Hi, I know (from the zfs-discuss archives and other places [1,2,3,4]) that a lot of people are looking to use zfs as a storage server in the 10-100TB range. I''m in the same boat, but I''ve found that hardware choice is the biggest issue. I''m struggling to find something which will work nicely under solaris and which meets my expectations in terms of hardware.

Setup: Osol.11 build 109 Athlon64 3400+ Aopen AK-86L mobo adeptec 1250sa Sata PCI controller card [re-posted from accidental post to osol `general'' group] I''m having trouble with an adaptec 1205sa (non-raid) SATA PCI card. It was all working fine when I plugged 2 used sata 200gb disks of a windows xp machine into it. Booted my osol server and added a zpool mirror using those

Hi all. Im pretty new to the whole OpenSolaris thing, i''ve been doing a bit of research but cant find anything on what i need. I am thinking of making myself a home file server running OpenSolaris with ZFS and utilizing Raid/Z I was wondering if there is anything i can get that will allow Windows Media Center based hardware (HTPC or XBOX 360) to steam from my new fileserver? Any help

Nothing like a "heart in mouth moment" to shave tears from your life. I rebooted a snv_132 box in perfect heath, and it came back up with two FAULTED disks in the same vdisk group. Everything an hour on Google I found basically said "your data is gone". All 45Tb of it. A postmortem of fmadm showed a single disk failed with smart predictive failure. No indication why the

Which consumer-priced 1.5TB drives do people currently recommend? I had zero read/write/checksum errors so far in 2 years with my trusty old Western Digital WD7500AAKS drives, but now I want to upgrade to a new set of drives that are big, reliable and cheap. As of Jan 2010 it seems the price sweet spot is the 1.5TB drives. As I had a lot of success with Western Digital drives I thought I would

I have been searching this forum and just about every ZFS document i can find trying to find the answer to my questions. But i believe the answer i am looking for is not going to be documented and is probably best learned from experience. This is my first time playing around with open solaris and ZFS. I am in the midst of replacing my home based filed server. This server hosts all of my media

Hi all, I would like to knwon if with ZFS it''s possible to do something like that : http://tldp.org/HOWTO/LVM-HOWTO/removeadisk.html meaning : I have a zpool with 48 disks with 4 raidz2 (12 disk). Inside those 48 disk I''ve 36x 3T and 12 x 2T. Can I buy new 12x4 To disk put in the server, add in the zpool, ask zpool to migrate all data on those 12 old disk on the new and

I have just installed EON .599 on a machine with a 6 disk raidz2 configuration. I run updimg after creating a zpool. When I reboot, and attempt to run ''zpool list'' it returns ''no pools configured''. I''ve checked /etc/zfs/zpool.cache, and it appears to have configuration information about the disks in place. If I run zpool import, it loads

Hey folks, I guess this is an odd question to be asking here, but I could do with some feedback from anybody who''s actually using ZFS in anger. I''m about to go live with ZFS in our company on a new fileserver, but I have some real concerns about whether I can really trust ZFS to keep my data alive if things go wrong. This is a big step for us, we''re a 100% windows

I was trying to simply test bandwidth that Solaris/ZFS (Nevada b63) can deliver from a drive, and doing this: dd if=(raw disk) of=/dev/null gives me around 80MB/s, while dd if=(file on ZFS) of=/dev/null gives me only 35MB/s!?. I am getting basically the same result whether it is single zfs drive, mirror or a stripe (I am testing with two Seagate 7200.10 320G drives hanging off the same interface

I have a raidz2 pool with one disk that seems to be going bad, several errors are noted in iostat. I have an RMA for the drive, however - no I am wondering how I proceed. I need to send the drive in and then they will send me one back. If I had the drive on hand, I could do a zpool replace. Do I do a zpool offline? zpool detach? Once I get the drive back and put it in the same drive bay..

I''ve seen the Nexenta and EON webpages, but I''m not looking to build my own. Is there anything out there I can just buy? -Kyle

I figured the following ZFS ''success story'' may interest some readers here. I was interested to see how much sequential read/write performance it would be possible to obtain from ZFS running on commodity hardware with modern features such as PCI-E busses, SATA disks, well-designed SATA controllers (AHCI, SiI3132/SiI3124). So I made this experiment of building a fileserver by

I''m putting together a NexentaOS (b65)-based server that has 4 500 GB drives on it. Currently it has two, set up as a ZFS mirror. I''m able to boot Nexenta from it, and it seems to work ok. But, as I''ve learned, the mirror is not properly redundant, and so I can''t just have a drive fail (when I pull one, the OS ends up hanging, and even if I replace it, I have to
