[Just do not want to be misleading] I think there is one aspect of the Zhou style is heavily misleading. And that is how do we deal with ladies. Personally, I have my opinions about ladies being open and career-minded, but those are not important. What is important, would be how should we deal with ladies at a professional level. To me personally, if a lady claims to me as a professional, not as a female, then I will take her as a professional, and will consider very little of the general policy for being a gentleman. Otherwise, it would not be fair in corporations, in my personal view. But if the lady does not claim professional to me, then my approaches would be completely different. [and those approaches are not for sharing, since they are not IT related.] I don't know if this email is even relevant to the list discussion. I will leave that conclusion to the smart mail server policy here. :-) But if I have sent through some misleading text, this email is for the clarification.

I think NOR is 25 years old, and MLC and SLC FLASH are both NAND right? NOR and NAND have completely different behavior and implementation, and even within NAND the number of tolerated write cycles varies wildly MLC vs SLC and vendor vs vendor. Also wasn't someone saying the cheapo USB sticks do wear leveling in 16MB chunks, so if one of the chunks is hotter than others you might blow it sooner than you expect based on device-wide write cycles * size / bandwidth? software people would assume the wear leveling chunk size is the entire device, otherwise what does ``level'' mean, but apparently the electrical engineer monkeys have a different idea. The quality or chunk-size of wear leveling could vary from one device to another. I think hard disks are a little different in their failure behavior after increasing 100x in capacity, too, though. re Trivia: Sun has been shipping flash memory for nearly its re entire history. are you talking about the firmware? because that's NOR FLASH which is completely different. I'm not saying don't use it, but this sounds too much like Apple telling us 400 megaBIT/s firewire is faster than 80 megaBYTE/s parallel-SCSI. re It occurs to me that you might be too young to remember that re format(1m) was the tool used to do media analysis and map bad re sectors before those smarts were moved onto the disk ? ;-) yeah im old enough to remember. the smarts stayed redundantly in format long after it was moved into the disk. I thought one of those netapp .pdf's said they deliberately tell some of their SCSI/FC disks to stop doing reallocation and pass bad block errors up the stack. but aside from that all these SCSI disks do it, even the 5.25 ones. I'm old enough to remember that every SCSI Sun system I've used including even VME-based systems and Sun3/60's use SCSI disks which would do their own bad block remapping. I haven't used SMD disks. I used ST506 and ESDI disks in peecees, and with those you got a sheet of dot-matrix printout taped to the top of the drive by the manufacturer. The factory test for bad sectors with special controller boards that you don't have, to find marginal sectors you will miss if you do your own ``low-level format'' scan---although the disk layer does have to do remapping, and although you do scan for bad sectors during low-level format, with ST506 and ESDI disks you will not scan any bad sectors not marked on the printout unless your disk is failing, and you must use the printout to avoid marginal sectors. pgpNnGjvgyNHJ.pgp Description: PGP signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Do you happen to have more details about this problem? Or some pointers? We have 3 x2200m2 servers that we added pairs of these drives (specifically, the HD753UJ variant: 750GB instead of 1TB) to. We set up small (40G or so, I forget; we didn't really need the space, but buying smaller disks wasn't significantly cheaper) SVM mirrors on two of these machines, and a small SVM mirror plus a large zpool on the third. Within two weeks, all three machines had dropped a disk in some manner. The behavior we saw goes like this: metastat reports errors, output of 'format' changes for the dropped disk but still shows the disk. If the disk is moved to another machine (a different chipset; i.e., with another controller) then it shows up fine, all data intact, everything hunky-dory. We didn't lose data, but we did lose an SVM array and had to restore from backups. We replaced the drives with 4 Maxtors and 2 Seagate ES2s. None have reported problems yet. I don't know of any other solution, if you don't want to add a controller. It doesn't appear to be a problem with the drives, or a problem with the chipset, but the combination of drive+chipset causes wonkiness. Google shows some users having problems with this under XP, so it's probably not just a driver issue. This was what made me suspect the combination was a bad one, and further testing shows that that's probably the case: the drives work on other controllers, and other drives work on these controllers. The drives themselves are still working fine; we moved them to a SCSI-sata jbod with a non-nV controller and they're happy there.

I think 250 drives were around $200 at the time, so let's say the system price was $1200. I don't think there's a Sun server that takes 4+ drives anywhere near $1200.

I have trouble justifying Sun hardware for many business applications that don't require SPARC, let alone for the home. For custom systems that most tinkerers would want at home, a shop like Silicon Mechanics (http://www.siliconmechanics.com/) (or even Dell or HP) is almost always a better deal on hardware. I agree completely. About a year ago I spent around $800 (w/o drives) on a NAS box for home. I used a 4x PCI-X single-Xeon Supermicro MB, a giant case, and a single 8-port Supermicro SATA card. Then I dropped a pair of 80 GB boot drives and 9x 500 GB drives into it. With raidz2 plus a spare, that gives me around 2.7T of usable space. When I filled that up a few weeks back, I bought 2 more 8-port SATA cards, 2 Supermicro CSE-M35T-1B 5-drive hot

You can't trust any hard drive. That's what backups are for :-). Laptop hard drives aren't much worse than desktop drives, and 2.5 SATA drives are cheap. As long as they're easy to swap, then a drive failure isn't the end of the world. Order a new drive ($100 or so), swap them, and restore from backup.

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
I'm looking to do the same thing - home NAS with ZFS. I'm debating several routes/options, and I'd appreciate opinions from folks here. My system will primarily be a file music server, serving CIFS and some NFS as well as driving multiple concurrent audio streams via SqueezeCenter, and perhaps eventually videos via something like MythTV. I'm also contemplating making it a Sun Ray server. I don't want to run out of disk space for a long time - I'd like = 3TB to start. Decision #1: AMD vs. Intel I'm drawn to quad core, perhaps for silly reasons. I'm also drawn to AMD (for price and RAM performance). And finally I'm drawn to ASUS motherboards because there are so many options in the HCL. I want lots of SATA ports and support for 8GB RAM - option a: ASUS M3A-H/HDMI ($...@newegg) with AMD Phenom 9600 ($...@newegg) - option b: ASUS P5K Deluxe ($...@newegg) with Intel Quad Q6600 ($...@newegg) Any reason to go with Intel? Any better option going the AMD route (perhaps the Quad core chip offers no value?) Decision #2: 1.5TB Seagate vs. 1TB WD (or someone else) I've heard lots of stories about Seagate reliability being poor, especially in RAID configurations. WD has a good reputation, especially with their more expensive E3 drives. Reliability is a concern both from a time point of view (spending time getting/installing replacements and downtime until it is in), as well as potential data reliability if a multiple-failure occurs. - option a: 3 1.5TB Seagate drives (in Raid-Z) or 4 1.5TB in Raid-Z2 ($...@newegg) - option b: 4 1TB WD drives (in Raid-Z) or 5 in Raid-Z2 - option b(1): WD RE3 drives ($150 via eBay seller) - option b(2): WD Caviar Black ($...@newegg) - option b(3): WD Caviar Green ($...@newegg) Do I loose much in performance going Green vs. Black? Do I gain anything in reliability? Anything measurable (given other system components) in power savings? Decision #3: Raid-Z vs. Raid-Z2 I understand that with very large drives, the chance of a momentary block read failure is near (or in excess) of the 1/# blocks on disk (so you would likely get one of these if reading/copying the entire 1-1.5TB), and while subsequent re-tries would fix this it would be seen as a RAID failure in the moment. But the more I read up on ZFS, the less likely a double-fault situation appears that it'd occur, given the fix-on-error-detection and continuous cleaning of the disk. - option a: Raid-Z - option b: Raid-Z2 Decision #4: file system layout I'd like to have ZFS root mirrored. Do we simply use a portion of the existing disks for this, or add two disks just for root? Use USB-2 flash as those 2 disks? And where does swap go? - option a: [3 disks] - option a(1): reserve ~50GB from all three, ZFS mirror across all three, and put swap into that 50GB - option a(2): reserve ~50GB from all three, ZFS mirror across first two, and put swap into the third 50GB (rather large that...) - option a(3): reserve ~50GB from all three, ZFS mirror across first two, and put swap into that 50GB; ignore the 50GB in the third - option b: [4 disks] - option b(1): reserve ~25GB from all four, ZFS pool/mirror across all four, and put swap into that pooled 50GB - option b(2): reserve ~50GB from all four, ZFS mirror across first two, and put swap into the third 50GB (rather large that...) and ignore the fourth 50GB - option b(3): reserve ~50GB from all four, ZFS mirror across first two, and put swap into the third 50GB (rather large that...) and ignore the fourth 50GB - option b(4): reserve ~50GB from all four, ZFS mirror across first two, and put swap into that 50GB (rather large that...); ignore the third and fourth 50GB - option c: [5 disks] - option c(n): you get the idea... - option d: [n disks + 2 root disks] - option d(1) use some small cheap pair of SATA (or even IDE) disks for mirrored root/swap - option d(2) use ~8GB USB2 flash drives for mirrored root/swap (and place things like /opt into the larger data array) Many thanks for your feedback!

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
Dude, How much is your time worth? Consider the engineering effort going into every Sun Server. Any system from Sun is more than sufficient for a home server. You want more disks, then buy one with more slots. Done. Search http://store.sun.com; for the item that matches your needs and run with it. Sun currently has a promotion on X4150 Servers... That will easily be able to serve NFS, SunRay, etc... to your home. I believe when you factor in all the hardware (motherboard, cpu, memory, disks, cabling, power supply, case, etc.) and all your time (installation, testing, debugging, testing, hardware DOAs, testing, waiting for replacements, testing, repairing/replacing faulty consumer grade drives, testing...), I think you will quickly find the current X4150 server to be a compelling deal. I currently own/use an X2100 server for the same purpose without issues. Cheers, Joel. Proud to be Flying Our Own Dog Food ;-) Decision #1: Buy an engineered box. http://www.sun.com/servers/x64/x4150/ http://shop.sun.com/is-bin/INTERSHOP.enfinity/WFS/Sun_NorthAmerica-Sun_Store_US-Site/en_US/-/USD/ViewStandardCatalog-Browse?CategoryName=HID-2133736376CategoryDomainName=Sun_NorthAmerica-Sun_Store_US-SunCatalog * Quad-Core Intel, 4GB RAM ... Promotional Priced... $2035. Get a real/tested box. Forget the hassles. Decision #2: * With disks, you get what you pay for What does Sun use... * Be careful at/beyond 1TB for Boot Drives Decision #3: * What is your data production requirements? * Keep in mind RAID-Z2 with 3 disks is essentially 3way mirror... * Have you considered Mirrored? * How many disks are you planning on having in the system? * Performance, Space, Protection: Choose 2.

Do we simply use a portion of the existing disks for this, or add two disks just for root? Use USB-2 flash as those 2 disks? And where does swap go? The default install in Osol 0811 (which is what I just upgraded my home NAS to) gives you a zfs root pool that various things, including swap, are taken out of as filesystems or whatever. (You can then attach another chunk of space to make that root pool mirrored, if you want; I've done that, using two dedicated disks for it.) Actually, I don't think you can really control how the 08-11 install sets up its root. Because of the cost of hot-swap slots in a box, it might make sense to share root and data on two drives, maybe. I haven't gone that route myself. I haven't experimented with SSD in Solaris. I'm using one as the system drive for an XP box, and it's giving me terrible pause problems (I think this is an understood problem, I just bought too early, and haven't been able to afford to junk my current SSD and replace it with an even more expensive one). So make sure to get current research and figure out which ones will be good for what you're doing before spending money! What are your backup plans? RAID (or mirroring) is just the start, to protect you from many hardware issues. (The size of your array makes this more of an issue; mine is two 400GB mirrored pairs, so I can back it up to an external 1TB drive easily.) -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info -- David Dyer-Bennet, d...@dd-b.net; http://dd-b.net/ Snapshots: http://dd-b.net/dd-b/SnapshotAlbum/data/ Photos: http://dd-b.net/photography/gallery/ Dragaera: http://dragaera.info ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

You want more disks, then buy one with more slots. Done. In my experience, buying disks (or disk-related things---JBODs, NASs, etc.) from Sun is frustratingly expensive. Sure, the x4150 linked later is a good deal (if you don't mind spending a couple grand on a home system), but it only takes 2.5 drives inside it. Even with 146GB SAS drives (the largest bundled with it) 8 drives doesn't give 3TB. So, you need an external SAS or SCSI card at $500, and a place to put more (preferably 3.5) disks. Follow, if you will, the trek of someone attempting to do that at home. Let's see... Sun.com, storage, find a product. Disk storage, that's right. Ah! The J4200 looks like just the thing. I want it with 4 1TB disks, so pick the model that includes 2 and add 2 more. Throw in a SAS cable so I can attach this to the x4150. Now take a look at the price... $5600. Add the host and the SAS card and the total is $8100 for a lousy 3 TB of disk space. I can't (for home use) warrant spending $8k for a file music server , I don't care how well-tested it is, I can buy eight different kinds of hardware with 3TB of disk space for that, and I'd wager at least three of them would work out of the box, and then I'd have more available disk space than the Sun solution. For small enterprises like a home media box, I don't see the point of big, expensive, loud (!) machines like the x4150 et al. Decision #2: 1.5TB Seagate vs. 1TB WD (or someone else) The 1.5TB drives have a sketchy reputation as compared to any other Seagate drives.

The reason they're so cheap is because they're the same 7200.11 form factor as the rest of the line-up so the cost difference to produce them (from what i understand) is negligible.

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
So I have just finished building something similar to this... I'm finally replacing my Pentium II 400Mhz fileserver! My setup is: Opensolaris 2008.11 http://www.newegg.com/Product/Product.aspx?Item=N82E16813138117 http://www.newegg.com/Product/Product.aspx?Item=N82E16820145184 http://www.newegg.com/Product/Product.aspx?Item=N82E16819103255 http://www.newegg.com/Product/Product.aspx?Item=N82E16811129025 (there is no power supply here I had one of those too) I ended up paying $278 The case and everything makes it super quiet, and it runs very cool. Still have a power test to run and see but I'm guessing 125 - 150 watts. I had hard drives available, and using a USB DVD/CD drive for installation I am using 2 ATA drives mirrored for the root pool I am using 6 500GB (hitachi) sata drives in raidz for data with the onboard interface. The initial iozone test I ran, under ideal block sizes etc, I could sustain enough to saturate the 1GB interface. Real world, I haven't been able to see what my real utilization is. I use this mostly to store media (movies, mp3s, etc) which I play with a mythtv box (just using NFS as the share). Also planning to use this as a backup server for the other machines in the house (considering running Amanda at home for this) I'm usually not doing heavy file I/O, so I've also put a virtual machine on here with virtual box for casual use for other stuff. During the process I swapped the whole thing to ubuntu on a usb flash and ran the opensolaris fileserver as a VM with VMWare...but I ended up just not happy with that in the end. The usb flash I had was OK, but it's not a hard drive. With opensolaris, I can still play flash stuff from Hulu fullscreen in HD with the onboard video. I've been trying to remember why I still need windows for a desktop and have been debating just killing that PC as well. Most of the things that I used windows for (ripping a DVD, etc) can be done with a VM with virtualbox...it's slow, but it works. I also don't re-encode video at all. I don't know if mythtv will actually run on opensolaris...that would be cool if it did. As far as a fileserver that has capacity to do other stuff, I'm very happy with this setup. As for the person who suggested a Sun x4150. Those are extremely loud because of the fans. There is no way I could run one of those at my house because of that. It was designed for a datacenter (and I have run them there). -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

But do I have to spell this out to you -- somethings are invented not for home use? Yeah, I'm sincere, but I've ordered more or less the same type of hardware for commercial uses in the past. There are a number of uses for big, slow, cheap storage systems. Disk-based backup is an easy one--from a price/capacity standpoint, it's really hard to beat a rackload of 4U systems stuffed full of cheap disks. Not every application needs redundant power, multi-pathed disks, highly-engineered servers, and a fleet of support engineers waiting for your call. In my experience, very few applications actually need that--cheap, somewhat reliable systems with good replication and failover usually beat enterprise-grade hardware anytime that the cheaper hardware is even an option. If you have a high transaction rate, a need for perfect coherency and consistency, and failure is expensive, then spending 3-10x the money for slightly higher performance and slightly lower failure rates makes perfect sense. Then again, I'm used to having enough quantity flying around to make the cost differences worth it. Spending 100 hours of staff time to save $2k up front is dumb. The last time I built commercial storage servers like this, it took about two extra months of my time dealing with vendors and qualifying hardware, but we shaved $250k off of a $350k budget when the company was strapped for cash. That was an easy call. It's all about quantifying your risks and knowing what you really need. In my experience, any time you can make software-based replication do what you want, and you aren't paying massive per-server software license fees, you're probably better off with a larger number of cheaper systems vs. a smaller number of more expensive systems.

Since you are using the rge driver, you might be getting bit by CR6686415. http://bugs.opensolaris.org/view_bug.do?bug_id=6686415 The symptoms are that some packets work, more likely with small packets like pings, but large packets might not work. I've also had trouble not being able to talk to systems on my LAN, but able to get to the internet. Try the workaround in the CR. -- richard Peter Bridge wrote: Thanks for the replies, it seems like I may have to rewind a bit here and fix some network issues on the solaris box before I can move forward with the OSX connecting... As I mentioned, ping between boxes works fine. I can ping my osx box, my router (192.168.1.1) and my other NAS. But I last night I decided to have a try with SMB since I wasn't getting far with NFS. That's when I discovered the Solaris box can't connect to the internet (needed to download some smb packages, or are they on disk somewhere?). Anyway I took the approach of doing a clean install, since I've played around with so many things trying to get NFS working. So after a clean install I noticed again that the dhcp had failed to assign ipaddress to the interface. So I started patching again things that seem to be missing, the hostname.rge0 file was missing, so I added an entry with my hostname (zfsnas). I also had to tweak the hosts file and add 'dns' to nsswitch.conf and create a file resolv.conf. So here is my current setup: [EMAIL PROTECTED]:~# ifconfig -a lo0: flags=2001000849UP,LOOPBACK,RUNNING,MULTICAST,IPv4,VIRTUAL mtu 8232 index 1 inet 127.0.0.1 netmask ff00 rge0: flags=201000843UP,BROADCAST,RUNNING,MULTICAST,IPv4,CoS mtu 1500 index 2 inet 192.168.1.122 netmask ff00 broadcast 192.168.1.255 ether 0:1c:c0:8e:a:3d lo0: flags=2002000849UP,LOOPBACK,RUNNING,MULTICAST,IPv6,VIRTUAL mtu 8252 index 1 inet6 ::1/128 [EMAIL PROTECTED]:~# cat /etc/hostname.rge0 zfsnas [EMAIL PROTECTED]:~# cat /etc/hosts 127.0.0.1 localhost 192.168.1.122 zfsnas zfsnas.local loghost [EMAIL PROTECTED]:~# cat /etc/nodename zfsnas [EMAIL PROTECTED]:~# cat /etc/defaultrouter 192.168.1.1 [EMAIL PROTECTED]:~# cat /etc/nsswitch.conf ... hosts: files dns ...

Should I switch from nwam to a manual configuration? or should nwam be able to handle this. It seems strange already the the dhcp default setup fails. Anyway, I don't need internet access from this box, I was just trying to workout how to download and install SMB. But it did make me wonder if this might be related to routing issues that might also affect the NFS stuff... With regard to ZFS, I have a mirrored pool of two disks 'data' and I create a fs as follows: [EMAIL PROTECTED]:~# zfs create -o casesensitivity=mixed data/backup [EMAIL PROTECTED]:~# zfs set sharenfs=on data/backup [EMAIL PROTECTED]:~# zfs set atime=off data Next I used system - administration - shared folders to add the /data/backup directory for sharing with any computer in my LAN. This seemed to work previously, but now I'm noticing that since my fresh install nothing gets remembered. WHen I re-open the shares gui, the previous share is gone. Any tips on this one too? Sorry for so many questions, but I'm quite new to all this, but determined to get things working now that I bought some specific hardware for the job. Would it be worth trying with 2008-11 i noticed a 101a rc1b build that's now available, or is it going to be too newbie unfriendly? ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
Just as a follow up. I went ahead with the original hardware purchase, it was so much cheaper than the alternatives it was hard to resist. Anyway, OS 2008-05 installed very nicely. Although it mentions 32bit while booting, so I need to investigate that at some point. The actual hardware seems stable and fast enough so far. The CPU fan is much louder than I expected, so I'll probably swap that out since I want this box running 247 in the office and can't stand noisy machines. Anyway I'm booting from a laptop ide drive with two sata disks in a mirrored zpool. This seems to work fine although my testing has been limited due to some network problems... I really need a step-by-step 'how to' to access this box from my OSX Leopard based macbook pro. I've spent about 5 hours trying to get NFS working with minimal progress. I've tried with nwadm disabled, although the two lines I entered to turn it off seemed to miss alot of other config items, so I ended up turning it back on. The reason I did that was the dhcp was failing to get an address, or that's what it looked like, so I wanted to try static address. Anyway I found a way for using a static address with nwadm turned on. Anyway, to cut a long story short, I can now ping between the machines, they have identicle users created id=501 and groups with id=501, but OSX just refuses in anyway to connect to the NFS share, from command line with various flag, or cmd k. I'm going to clean install open solaris in the morning, maybe with the newest build 100? and try again, but I'd really appreciate some help from someone that has got this working. -- This message posted from opensolaris.org ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

pb == Peter Bridge [EMAIL PROTECTED] writes: pb I really need a step-by-step 'how to' to access this box from pb my OSX Leopard What you need for NFS on a laptop is a good automount daemon and a 'umount -f' command that actually does what the man page claims. The automounter in Leopard works well. The one in Tiger doesn't---has quirks and often needs to be rebooted. AFAICT both 10.4 and 10.5 have an 'umount -f' that works better than Linux and *BSD. You can use the automounter by editing files in /etc, but a better way might be to use the Directory Utility. Here is an outdated guide, not for Leopard: http://www.behanna.org/osx/nfs/howto4.html The Leopard steps are: 1. Open Directory Utility 2. pick Mounts in the tab-bar 3. click the Lock in the lower-left corner and authenticate 4. press + 5. unroll Advanced Mount Parameters 6. fill out the form something like this: Remote NFS URL: nfs://10.100.100.149/export Mount location: /Network/terabithia/export Advanced Mount Parameters: nosuid nodev locallocks [x] Ignore set user ID privileges 7. Press Verify 8. Press Apply, or press Command-S the locallocks mount parameter should be removed. I need it with old versions of Linux and Mac OS 10.5. I don't need it with 10.4+oldLinux, and hopefully 10.5+Solaris won't need it either. There is a 'net' mount parameter which changes Finder's behavior. Also it might be better to mount on some tree outside /Network and /Volumes since these seem to have some strange special meanings. ymmv. At my site I also put 'umask 000' in /etc/launchd.conf to, errmatch user expectations of how the office used to work with SMB. For something fancier, you may have to get the Macs and Suns to share userids with LDAP. Someone recently posted a PDF here about an ozzie site serious about Macs that'd done so: http://www.afp548.com/filemgmt_data/files/OSX%20HSM.pdf Another thing worth knowing: macs throw up these boxes that say something like Server gone. [Disconnect] with a big red Disocnnect button. If your NFS server reboots, they'll throw one of these boxes at you. It looks like you only have one choice. You actually have three: 1. ignore the box 2. press the tiny red [x] in the upper-left corner of the box 3. press disconnect If you do (3), Mac OS will do 'umount -f' for you. At the time the box appears, the umount has not been done yet. If you do (1) or (2), any application using the NFS server (including potentially Finder and all its windows, not just the NFS windows) will pinwheel until the NFS server comes back. When it does come back, all the apps will continue without data loss, and if you did (1) the box will also disappear on its own. The error handling is quite good and in line with Unixy expectations and NFS statelessness. pgpHWSn6AhMy6.pgp Description: PGP signature ___ zfs-discuss mailing list zfs-discuss@opensolaris.org http://mail.opensolaris.org/mailman/listinfo/zfs-discuss

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
You have not described your requirements (low-power ??, low-cost ??). But I'll contribute some pointers anyway! :) Well for a home NAS I'm looking at noise as a big factor. Also for a 24x7 box, power consumption, that's why the northbridge is putting me off slightly. So far the other solutions mentioned here, and what I've found on various blogs are going to be a lot more noisy and power hungry. Although the cost also makes this option very attractive, I'd be happy to pay a bit more for something with more grunt so long as it's quiet and energy efficient. Although I don't really mind if the box is slow, with ZFS what I'm looking for is secure data storage. But with only two SATA ports I don't see how this board will quite acheive that. Unless I boot from USB and use 2 SATA and 2 IDE drives. btw I'm seeing mixed reports if the D945GCLF2 is seen as 64 bit by solaris.

I just built a homeserver that pulls 62 watts from the plug at idle for ~$700. I had some of the parts lying around but even if you bought everything at frys you should be able to set yourself up for under 1K for the next 3-5 years. Seasonic 80 plus 300 watt power supply Intel DP35DP motherboard (onboard nic is an intel, has 6 sata from ich9) E5200 Wolfdale processor (5 watts at idle, 30 watts at load) 4 x 1TB Samsung EcoGreen 5400 rpm harddrives 4GB ram 80GB laptop harddrive I had lying around for the system disk Ati PCI 9200 video card I had lying around (pulls 2-3 watts) Cheapest mid tower case off newegg with free shipping The samsung drives are great, they don't ever spindown. I had problems with some seagates a year or so back where the drive firmware would spin them down after 90 seconds of inactivity. The samsungs just chug along at 4-5 watts each. I use raidz on the 4 1TB drives and set copies=2 on the system drive. The real power savings is from the cpu. Any dual core 45nm intel chip idles at unbelivably low wattage. Add the 5400 rpm drives and you've got a nice cool running, quiet, low power system. If I only needed 1 TB I'd probably use the atom board with the two ports and a usb jump drive for the system disk, but I needed more space.

It's a little slow if you're building a desktop box, but fine if you're just doing lightweight browsing, word processing etc. Note that the board chipset consumes more power than the Atom CPU. A typical system based on this board will consume around 55 Watts. The other good news - this board costs about $80 (including the soldered in CPU).

But I'll contribute some pointers anyway! :) See this article entitled: G31 And E7200: The Real Low-Power Story October 10, 2008 – 1:50 AM – Motherboards at: http://www.tomshardware.com/reviews/intel-e7200-g31,2039.html The E7200 dual-core (2.53GHz with 3Mb of cache) is a sleeper product IMHO. Low power (well below the published 65W power envelope), plenty of grunt and priced to go. Couple this chip on a system with 4 or 8Gb of RAM and you have a winner. For example, consider the mid tier system here: http://www.techreport.com/articles.x/15737/5 (the motherboard is $126) with an e7200 CPU and 2 memory kits from here: http://www.amazon.com/s/ref=nb_ss_gw?url=search-alias%3Dapsfield-keywords=KVR800D2K2%2F4GRx=0y=0 Also, take a look at: http://www.newegg.com/Product/ProductList.aspx?Submit=ENEN=2010170147%201052108080%201052420643%201052315794%201052516065name=5 - look at the pricing *after* rebates and you're looking at brand-name memory (2 * 2Gb = 4Gb total) for $65 here: http://www.newegg.com/Product/Product.aspx?Item=N82E16820227298 With ZFS - the most important hardware component is RAM. Get as much RAM as your motherboard will support (along with any budgetary constraints). My advice is the E7200 CPU, 8Gb of RAM and you'll have a smile on your face every time you use this system. If you want a small system that is pre-built, look at every possible permutation/combination of the Dell Vostro 200 box. Yes - I just put together a system based on this box and made a few modifications - like replacing the PSU with a Corsair VX450W, added 4 * 1Gb of RAM and an ATI Radeon 4850 (BTW Nvidia is much better supported under OpenSolaris). This system was built as a cost effective gamer box - but it would make a great ZFS box for 2 to 4 SATA drives (with the upgrades listed above [minus the graphics card]). Email me offline if I can answer any further questions. PS: It'll probably take you 2 or 3 hours to evaluate every combination possible of the dell Vostro 200 box - but the price/performance is unbeatable and it's hard to put together a comparable system, from parts, for less money. Obviously Dell gets Intel processors for way less than you and I.

Re: [zfs-discuss] ZFS + OpenSolaris for home NAS?
thanks for all the feedback. Some followup questions: If OS will see all 4 cores, will it also make use of all 4 cores for ZFS. ie is ZFS fully multi threaded? Is there any point to run ZFS over just two 2 disks? without the extra sata ports I'm thinking I may have to abandon this idea. The plan was to use the internal ide just for a small boot disk and cdrom. I don't think it would be a good idea to mix ide and sata zfs, agreed?

oops, I mean 2 cores. Anyway I'm having second thoughts about this board now because the northbridge sounds like a power hog and I was planning a passive cooled system.

It depends on what your doing. I got a AMD Sempron Processor LE-1100 (1.9Ghz) doing NAS for mythtv and seems to do ok. If the board you quote is what your getting I think it is 64bit chip - intel site says its a Atom 330. Solaris will should use all its cores/threads - intel have added a load of code to opensolaris not sure if Atom stuff was in it. Think your out of luck for PCI SATA cards - not seen anything good about it.
