similar to: Advice on a cheap home NAS machine using ZFS

Hi all I want to look at setting up a simple / cheap SAN / NAS server using normal PIV motherboard, 2GB (or even more) RAM, Core 2 Duo CPU (probably a Intel 6700 / 6750 / 6800) & some SATA HDD's (4 or 6x 320GB - 750GB). My budget is limited, so I can't afford a pre-built NAS device. Can this be done with CentOS? I've been looking FreeNAS (which is built on FreeBSD), and it

So after toying around with some stuff a few months back I got bogged down and set this project aside for a while. Time to revisit. <BR><BR> Looking around there still is not a good "these cards/motherboards" work list. the HCL is hardly ever updated, and its far more geared towards business use than hobbyist/home use. So bearing all of that in mind I will need the

Greetings all. I am facing serious problems running ZFS on a storage server assembled out of commodity hardware that is supposed to be Solaris compatible. Although I am quite familiar with Linux distros and other unices, I am new to Solaris so any suggestions are highly appreciated. First I tried SXDE 1/08 creating the following pool: -bash-3.2# zpool status -v tank pool: tank state:

Hello all, I am thinking about a new laptop. I see that there are a number of higher-performance models (incidenatlly, they are also marketed as "gamer" ones) which offer two SATA 2.5" bays and an SD flash card slot. Vendors usually position the two-HDD bay part as either "get lots of capacity with RAID0 over two HDDs, or get some capacity and some performance by mixing one

This Asus board looks promising, assuming the parts (nForce 680a chipset) are Solaris friendly: http://www.asus.com.tw/products4.aspx?l1=3&l2=136&l3=486&model=1530&modelmenu=2 The board boasts 12 (!) SATA2 ports. The FX-7x series CPUs appear to be a very cost effective ($799) 4 core solution. Ian

I have a supermicro AOC-SAT2-MV8 and am having some issues getting drives to work. From what I can tell, my cables are to long to use with SATA2. I got some drives to work by jumpering them down to sata1, but other drives I can''t jumper without opening the case and voiding the drive warranty. Does anyone know if there is a system setting to drop it back to SATA1? I use zfs on a raid2 if

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

According to various posts the LSI SAS3081E-R seems to work well with OpenSolaris. But I''ve got pretty chilled-out from my recent problems with Areca-1680''s. Could anyone please confirm that the LSI SAS3081E-R works well ? Is hotplug supported ? Anything else I should know before buying one of these cards ? Thanks, Arnaud

Some background - I have a couple of NetBSD (i386) boxes and CentOS 5 boxes that I want to virtualise and I''m trying to work out which OS will be most suitable as the dom0. I have a desire to run at least RAID1 and ideally ZFS mirroring on the dom0 so I can have all the domU''s not have to worry about disk redundancy etc. My hardware : I have a brand new Intel E8200 core2duo and

Hi there, this is my first post to the list. I'm a newcomer to the linux world. I started using it on a regular basis on May and I must say I'm quite comfortable with it, even if I have to re-learn a lot of things. But this is not a problem, I will improve my knowledge with time. My main problem now is that I bought myself a new computer (described at the end of this e-mail) and I was

Hello, i have some questions about the new dovecot replication and mdbox format. my company has currently 3 old dovecot 2.0.x fileserver/backend with ca. 120k mailboxes and ca. 6 TB data used. They are synchronised per drbd/corosync. Each fileserver/backend have ca. 40k mailboxes im Maildir format. Our MX server is delivering ca. 30 GB new mails per day. Two IMAP proxy server get the

Hi all, we have just bought a sun X2200M2 (4GB / 2 opteron 2214 / 2 disks 250GB SATA2, solaris 10 update 4) and a sun STK 2540 FC array (8 disks SAS 146 GB, 1 raid controller). The server is attached to the array with a single 4 Gb Fibre Channel link. I want to make a mirror using ZFS with this array. I have created 2 volumes on the array in RAID0 (stripe of 128 KB) presented to the host

Currently I''m trying to figure out the best zfs layout for a thumper wrt. to read AND write performance. I did some simple mkfile 512G tests and found out, that per average ~ 500 MB/s seems to be the maximum on can reach (tried initial default setup, all 46 HDDs as R0, etc.). According to http://www.amd.com/us-en/assets/content_type/DownloadableAssets/ArchitectureWP_062806.pdf I would

Hi, more than a year ago I created a mirrored ZFS-Pool consiting of 2x1TB HDDs using the OSX 10.5 ZFS Kernel Extension (Zpool Version 8, ZFS Version 2). Everything went fine and I used the pool to store personal stuff on it, like lots of photos and music. (So getting the data back is not time critical, but still important to me.) Later, since the development of the ZFS extension was

Hi, as I have learned from the discussion about which SSD to use as ZIL drives, I stumbled across this article, that discusses short stroking for increasing IOPs on SAS and SATA drives: http://www.tomshardware.com/reviews/short-stroking-hdd,2157.html Now, I am wondering if using a mirror of such 15k SAS drives would be a good-enough fit for a ZIL on a zpool that is mainly used for file

Hi, my oi151 based home NAS is approaching a frightening "drive space" level. Right now the data volume is a 4*1TB Raid-Z1, 3 1/2" local disks individually connected to an 8 port LSI 6Gbit controller. So I can either exchange the disks one by one with autoexpand, use 2-4 TB disks and be happy. This was my original approach. However I am totally unclear about the 512b vs 4Kb issue.

Hi, I am running a samba 3.0.14a server on a 2.6.15.6 kernel, on a 4T - SATA2 NAS. The disks are formated in xfs and configurated in hard RAID5. Network is bonded with 2 Gbits links using 802.3ad agregation. The NAS is connected on a Gbits switch (Summit 400 - extreme Networks), also configured with dynamic sharing. I am trying to get the best performances in Reading/writting the NAS, and what I
