Does anyone else have a similar setup they can provide me some related experience on? Thanks, Gary Thanks, all, for the replies and insights. Just a followup: The factory heatsink was basically incapable of keeping the temp down under a heavy-processing port build, and BIOS was shutting down when the temp eventually climbed too high. xmbmon was my friend for tracking this; using ctls and ctlq on the output stream of the build effectively suspended it when it got around 60C so I could wait until the processor cooled down enough to continue. Doing a sync every second or so also postponed the eventual overheating for a while, but eventually it would creep up to the shutdown point. Replacing the heatsink with a gonzo big one seems to have solved the problem. As an aside, this is probably what also made me think some time ago that my SSD was flaky. Things just ran faster so the cpu overheated sooner. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org
Re: AMD Phenom II X4 temperature issues (was Re: hardware monitor)
Hello Gary, Also make sure there is no packed dirt on the heatsink -- I don't know about AMDs, but older Intel heatsinks often tend to accumulate a paper-like layer of dirt on the 'top' of heatsink grid, blocking the airflow. I once had several thermal shutdowns on my home PC before I found that. This does not seem to happen with newer heatsinks so they must have changed the design somehow =) Best wishes Eugene -Original Message- From: Peter Giessel Sent: Monday, August 05, 2013 8:23 AM To: Gary Aitken Cc: freebsd-questions@freebsd.org Subject: Re: AMD Phenom II X4 temperature issues (was Re: hardware monitor) You can also try shutting down (obviously), then removing the heat sink, put some thermal paste on the processor and reinstall the heat sink. Sometimes there isn't much (any) thermal paste there and the processor can't get the heat into the heat sink.

AMD Phenom II X4 temperature issues (was Re: hardware monitor)
Ok, so now I see that my cpu temperature shoots up pretty dang fast when a build is going on. I'm running an AMD Phenom II X4 with the AMD-supplied fan in an ASUS M4A89TD PRO / USB3 motherboard. The system works fine unless I start a cpu-intensive build. If I leave it unattended, after some time the system shuts down abruptly. I'm guessing it's because of excessive cpu temperatures. When doing port builds, or any cpu-intensive job, the temperature of the CPU goes from 45 to 50 in about 30 seconds. I pretty much have to manually suspend and resume the build process to keep it down. If I do that, I avoid the abrupt shutdown. Needless to say, this makes unattended operation a non-starter...

If you're idle temp is 45, that's too high. By using powerd, so it's 800MHz, and being idle I'm at around 26C, presumably. It peaks at 45C on parallel builds. In the meantime, you can set the maximum cpu speed, which I recommend powerd for. Here's a tip when shopping, get a big beefy heatsink with a standard fan size, and replace the fan with something beefier. Either that or water cooling. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Re: Software raid VS hardware raid
My other concern is what happens when one drive goes down if we use gmirror? Is it completelly transparent and bad drive can be hot swapped while server is running and rebuild started? I am thinking now about gpt+gmirror (including boot and swap) Artem Yes. In fact, you can test this by unplugging the data or power cable to a drive while the server is running. I've done this with consumer sata drives and, so far, not had a problem. The server stays up and running and disk access is not interrupted. I can then plug in a new disk and add it to the gmirror and the array rebuilds. I've not tried this with gpt, so I can't comment there. -Modulok- ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

The metadata is probably specific to that manufacturer and maybe to that model of controller. It's a good idea to get spares, because as Murphy is my witness, in an emergency that controller will not be available in the same town, district, country, or continent.

The controller would be a slight concern. But for what you've described doing I doubt it will be a big deal. The 3Ware may have a faster processor on it than say a generic onboard built-in. But since all we're talking here is a RAID 1 mirror my guess is it may not be a big enough difference to see. Writes will be just as if you are writing to 1 drive, reads will be faster. Maybe that 5% cpu load turns into 6% or 7%. I really don't want to deploy ZFS on a new server where all these site need to migrate because i am kind of don't fix it if it is not broken kind of guy. UFS+journaling+softupdates served us well for years and snapshots are available on ufs too. I understand; I've only played around with ZFS some on Solaris. I may move in that direction some day, but for now My other concern is what happens when one drive goes down if we use gmirror? Is it completelly transparent and bad drive can be hot swapped while server is running and rebuild started? I am thinking now about gpt+gmirror (including boot and swap) I've never actually hot-swapped one but I can't see any reason why not. You can't use the gmirror remove directive when a drive has failed, but you do a gmirror forget device , swap it, then just do gmirror insert device to insert the replaced drive into the mirror. When everything is working as it should gmirror is mostly 'automatic', e.g. after the insert the rebuild just starts. Main thing I appreciated about this is the server stayed up and online after one drive died. My two servers at home are my testbeds to test out things first before doing stuff to the ones at work. I just installed both to 9.1. The difference now is I've used GPT (gpart) and this is new to me. Previously everything was always fdisk and disklabel. Both these machines are setup on one drive at this point and I haven't yet gotten into the mirroring yet. With the old fdisk/disklabel it was simple to just mirror the entire drive itself (slice). The other approach is to mirror partitions. I think I may need to do this as I think this is the way you have to proceed in order to avoid having gpt and gmirror both trying to claim the last sector on the drive (metadata storage). -Mike ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Perhaps you could give us a little more details A problem with HW RAID is that if the controller breaks, you need to get an identical controller to replace it, or the data will be lost. With software raid, you can read the data on any machine that will boot FreeBSD. That is a great convenience compared to searching eBay for an obsolete controller with the proper rev level. We haven't noticed any speed disadvantage on modern multi-core hardware and RAID 1. The advantages of HW raid escape me - I understand that years ago it provided OS independence and reduced CPU load, but it no longer provides the former, and with 8 cores do you need the latter while waiting for a disk platter to spin? ZFS is worthwhile, too, especially since you have a good amount of memory. That would give you snapshots and some other desirable features, such as background scanning for defects that UFS doesn't have. about what the purpose of the server is? Mission-critical or low cost? Those two tends to be mutually exclusive... Surely the presence of SATA drives shows that low cost is essential. Mirroring and ZFS provide very important advantages.

The problem i see is that while i can find very affordable and good options they do not provide hardware raid or even if they do it is not the best hardware for freebsd. I prefer SW RAID, specifically ZFS, for two very large reasons: 1) Visibility: From the OS layer you have very good visibility into the health of the RAID set and the underlying drives. All of the lower end HW RAID solutions I have seen require proprietary software to manage the RAID configuration, usually from the physical system's BIOS layer. Finding good OS layer software to monitor the RAID and the drives has been very painful. If you don't know you have a failure, then you can't do anything about it and when you have a second failure you lose data. Running a HW RAID system and not being able to issue a simple command from the OS and see the status of the RAID scares me. 2) Error Detection and Correction: HW RAID relies on the drives to report read and write errors. With UNCORRECTABLE error rates of 10^-14 and 10^-15 and LARGE (1 TB plus) drives you are almost guaranteed to statistically run into UNCORRECTABLE errors over the life of a typical drive. ZFS has end to end checksums and can detect a single bad bit from a drive, if the set is redundant it can recreate the correct data and re-write it, effectively correcting the bad data on disk. NOTE: Larger, more expensive HW RAID systems address both of the above issues, but at a much higher cost in terms of money and management overhead. DISCLAIMER: I have been managing mission critical, cannot afford to lose it data under ZFS for over 5 years, with no loss of data (even with some horribly unreliable low cost HW RAID systems under the ZFS layer... if we had not used ZFS we would have lost data multiple times). -- Paul Kraus Deputy Technical Director, LoneStarCon 3 Sound Coordinator, Schenectady Light Opera Company ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

File system planned is UFS with journaling. I can't say for sure exactly what's best for your needs, however, please allow me to toss out some very generic tidbits which may aid you in some way. Historically back when RAID was new, hardware controllers were the only way to go. Back then I would never look at software RAID for a server machine. Best to offload as much work away from the CPU as possible to free it up for running the OS. What has changed is the amount of raw horsepower available from modern-day processors as compared to when RAID first came out. On the multi-core monster CPUs of today software RAID is a perfectly viable consideration because there are CPU cycles to spare, so the performance penalty is less now than it once was. Having said that, there are several other considerations to keep in mind as well. The type of RAID required matters. If you want/need RAID 5/6 it is definitely better to go with hardware RAID because of the horsepower required to do the XOR parity generation. You would want RAID 5/6 running on a hardware controller and not on the CPU. On the other hand, RAID 0, 1, and 10 are fine candidates for software RAID. One thing I've noticed that seems to somewhat get lost in this discussion is equating software-based RAID with not needing to spend money on the expensive RAID controller. At first glance it does seem like quite a waste to spend hundreds of dollars on a really fast RAID controller and then turn all its functionality off and just use it JBOD style. If you truly want performance you still need the processing power of the hardware chip on the (expensive) controller. Most central to this is I/Os per second. This matters more to some workloads than others, with being a database server probably at the top of the list where I/Os per second is king. The better the chip on the controller card the more I/Os per second. Another thing that matters less wrt to server hardware is the third kind of RAID known as fake or pseudo RAID. This is mostly found on desktop PC motherboards and some low-end (cheap) hardware cards. There is a config in the BIOS to set up so-called RAID, but it is only half of the matter - the other half is in the driver. FreeBSD does indeed have support for some of these fake RAID things but I stay far far away from them. Either go hardware or pure software only - the fakeraid is crap. Another thing I'd warn you about is the drives themselves. Take a look: http://wdc.custhelp.com/app/answers/detail/a_id/1397 Many people get very lucky much of the time and don't experience problems with this. Using drives designed for desktop PCs with RAID can be prone to problem. Drives designed for servers are more expensive, but I've always felt it is better to put server drives in servers. :-) In terms of a 'performance penalty' what you will find is it gets shifted away from just losing a few CPU cycles into other areas. If the drives are Advanced Format 4k sector critters and they aren't properly aligned in the partitioning phase of set up performance will take a hit. If the controller chip they are hooked up to is slow, then the entire drive subsystem will suffer. Another thing you will find that will surface as a problem area is the shift away from the old style DOS MBR scheme and towards GPT. Software RAID (and indeed hardware controllers too) store their metadata at the end of the drive and needs to be outside the file system. The problem arises when both the software raid and the GPT partitioning try to store metadata to the same location and collide. Just knowing about this in advance and spending some quality reading time about it prior to trying to set up the box will help greatly. Plenty has been written (even in this list) about this subject by people smarter than me so the info you need is out there, albeit it can be confusing at first. I guess what I'm trying to point out is that low performance wrt software RAID will stem from other things besides just simply consuming a few CPU cycles. Today's CPUs have the cycles to spare.

Not sure about your system, or what type of device you are considering, but if its going to be a USB dongle id go with Ralink chipset device.

Re: Hardware compatability question
Hi, it's not really about the machines but more the hardware. FreeBSD is quite diverse in what it can run on so best bet check the HCL's off the www.freebsd.org website as that would give you the best idea! Otherwise just install and see what works and doesn't. FreeBSD is pretty comprehensive of H/W support. I would say if you were moving away from MS, FreeBSD is a great choice and probably the best out there providing you don't need something specific - you will need to get used to the CLI environment but once that's worked out it's a sinch. I am now introducing *BSD to my company too and trying to move them away from Linux which has it's own caveats. Good luck with the move, I'd love to give you a full-blown sales pitch but unfortunatley don't have time right now. - though it would be kinda useless as FreeBSD really sells itself if you know what it can do for you!

[i386,sparc64,ia64,amd64] The ahd(4) driver supports the following: Adaptec AIC7901 host adapter chip Adaptec AIC7901A host adapter chip Adaptec AIC7902 host adapter chip *Adaptec 29320 host adapter* Adaptec 39320 host adapter Many motherboards with on-board SCSI support But after connecting this Adaptec 29320 to the system it shits the terminal from top to bottom and all I have are issues with it, that is called officially supported hardware? There should be [*] sign on that device that this device ID is known, but its support is less then good. Grepping the Internet shows that all people suggest to put that SCSI card directly into the bin and get something else to work on FreeBSD.

Today's problems seem to be suspend/resume/hibernate (all the variations of it's not switched on, but also not switched off entirely) and some specific sorts of wireless devices. Having a live disk is not likely to help for several reasons: 1. there aren't really the tools to see if something will actually work in a production environment (unless pc-bsd have a disc I don't know about). For instance, wifi maybe recognised but not actually work and error like crazy only once you start to use it. The main idea of using such a system is to most precisely determine the _present_ hardware to allow further investigations (e. g. web searches and mailing list questions). The OS from disc or stick can help to identify the hardware. If you're running a live file system from a USB stick, you can do things like: # dmesg # pciconf -lv # usbconfig # sysctl -a If you start the system by boot -v (verbose logging), dmesg will contain some more lines than usual. If you have a USB stick, you can easily save the output of those commands to persistent files. If you have X in the mix, you can also check the support for the display and obtain other information that might be important later on (especially GPU info): # glxinfo # xvinfo Log files worth saving are in /var/log, as well as Xorg.0.log for X-related things. If you prepare some programs, you can also do some testing, e. g. multimedia, gaming, 3D support, networking and so on. 2. The BIOS will get in your way - see recent thread regarding samsung laptop not installing. I don't think the salespeople will let you play with that either. Depends. If you're interested in buying one of the more expensive ones, they will offer you a test ride which includes that you have a look at the CMOS setup (which is something very typical for you as an IT professional). You can say: The BIOS is defective, it doesn't allow me to boot a standard OS. Let's see... for 100$ less, I would still do you a favour and buy it. :-) If you do this *and* get it to boot, you want to get a copy of pciconf -lv which will give you the best idea on whats what.

We really need to replace the entire unit, but that might be a bit more salable if I can present convincing evidence of the cause of the problem. Doug. First check the Power Supply voltages are correct, and not too noisy. You'll need a good DMM, and 'scope for that. Then, Visually examine the motherboard. Are any of the round can electrolytic cap's Bulging at the top, or showing some brown or green gunk leaking out from where they sit on the board. Likewise, it's often worth checking the low voltage caps in the PSU too. CAUTION! Lots of volts exist in places inside them, take care, leave it a few mins after unplugging before taking it apart. If so, it's not uncommon, you'll need to re-cap the Mobo, and or the PSU. Chances are, it's just one particular make/type that has failed, so if the others look OK, just change the failed ones. Get the same value and voltage, but if you can from a reputable manufaturer, Panasonic or some such. NOTE! It's not uncommon either, for some parts to be installed at manufature the wrong way round. It's amazing they last as long as they do before letting go. Also, at least one Mobo maker had the wrong polarity markings on the board. In those cases, you'll need to buzz out the associated power rail, comparing the polarity of the suspect part, with it's copanions on the same power rail. For some common Mobo's, if you google the model number, you'll find websites selling complete re-cap kits, or offering an exchange service. This is A LOT more common, than failing RAM, but can present itself in many and varied ways, from corrupted display's, to systems that wont boot. Laptops are not immune to this either. Also, Hard Drives can go funny with age, not failing as such, but the surface getting corrupted so that the drives own logic cant always unscramble the mess to the OS's satisfaction. Then, there is the situation (I had one recently) where a failing PSU, caused Hard Drive data corruption. Mr Gibson's product Spinrite is the tool to use to fix that (and it did!) Not free, but more than worth the weight of a CD, Floppy or USB stick in Gold! But you'll need to make sure the Mobo and everything else is OK. It also works on Floppy drives, if you Just HAVE to recover that data. If you have a fleet of machines, you should have your own copy. No affiliation, just a more than happy long term owner/user of that tool.

Hardware booting problem
I encountered a situation today that I do not understand. This is a very old i386 PC that does not have a usable CD drive. The existing drive uses a very funky SCSI connector that I have nothing for. The system disk is SCSI and there was one additional PATA drive used for additional storage. The PATA drive failed. It won't even stick around in /dev for more than a couple minutes after boot and there are lots of messages about bad sectors. The data is completely backed up and the that drive is over 5 years old. I removed the old drive and installed a new one. System will not boot. It hangs in the BIOS. Never gets around to installing the SCSI BIOS. My first guess was there was no boot sector on the SCSI drive. That seems unusual since my other systems boot off the SCSI drives just fine. This one used to also before I added the PATA drive. However, if I put the dead drive back in along with the new one, then it boots. This also implies that the boot sector was only on the PATA drive. But the PATA drive is for all intents and purposes dead. So how is it booting? Is there any way to look into the SCSI drive and see if there is a boot sector there? This is more a curiosity item as there are additional failures starting to occur in that computer. We are going to replace it. Its around 10 years old. ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

NFS performance will be almost intolerable without it. It used to be you could work around this, at cost of an increased risk of data loss if the server crashed, by turning off the ZIL; but as of 9.0 this is no longer allowed, so a ZIL device is pretty much mandatory.

Regards Graeme I cannot be sure that I have tried one individual stick in all slots but I know that I have had various sticks in various slots and all showed as 960MB. As far as I can tell this happened when I was converting this computer from a file server/desktop running 9 current to a freenas server. I rearranged all hard drives and removed some expansion cards (pci firewire, pci-e Sapphire) removed DVD drives and installed one CD drive. All in all I had my hands in the MB quite a bit and could have done something even though I was careful and always grounded myself. Of course, I had the power off whenever working inside the box. I will be taking the computer down in the next few days to add another drive to create a mirror. At that time I will do all that you recommended. i.e. Blow out the dust bunnies, double check all connectors, redress all cables and the run memtest.

OT: Strange memory reading (hardware)
Greetings I have a strange problem with memory on one of my computers. I have recently converted this computer to a NAS server. It is an Asus A8N-VM MB running freenas amd64. I have 4 one Gig memory sticks installed and as well as I can remember, it had always seen the 4 Gig of RAM. Most recently I had 9 current installed. The problem is not with freenas as it is absolutely hardware. I have tested with all of the sticks installed and with one at a time. When all of the sticks are installed, BIOS show a total of 2752 MB of RAM. If any of the sticks are installed alone in any of the four slots, BIOS then shows 960 MB instead of the 1024 one would expect. Quickly subtracting 960 from 1024 gets 64 MB missing. Hmmm, perhaps an address lead or data lead on the MB is open. This I can understand, but using any finagling factors I can think of, I can't get close to the missing total of 1344 MB (4096-2752). The freenas system runs quite well with the available memory but I was wondering if anyone could help me understand this problem. Thank you for reading this and i hope you are having a great day.

Hardware sensors on FreeBSD
I was wondering if anyone knew of better software for FreeBSD for monitoring hardware sensors like CPU temp and fan speeds. I'm using an athlon II x4 and the amdtemp driver seems like it's 20C below what it really is but does change. I've tried using mbmon and it detects the it87 chip but it never updates. It's as if whatever temps it finds at boot are what it'll always show, and the fan speed listed is a quarter of what it really is. I tried stress linux to test lmsensors to make sure it wasn't a motherboard issue and lmsensors works relatively fine. The voltages are junk but temperature seems accurate and varies with the load. I've yet to see any update about the openbsd sensors framework, and I imagine the patch is so old it won't apply cleanly. Is there a better method to monitor system health under FreeBSD or am I stuck with decade old software and a kernel driver that's off by 20C? ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Hi, Reference: From: Alejandro Imass a...@p2ee.org Date: Fri, 20 May 2011 11:08:21 -0400 Message-id: banlktikm6asm5uddryhqmb3w_ruxvd4...@mail.gmail.com Alejandro Imass wrote: Hi folks, I recently sent a hard drive to be recovered and I think they just ripped me off. I have the back-up drive and believe it or not it has the same exact symptoms and won't mount. So I want to send both drives to a REAL AND TRUSTED LAB for 2 things: 1) Forensics on the supposed head-replecement mumbo-jumbo/scam crap of the other lab 2) Recovery of the data of the back-up drive I guess this only happens once in a lifetime when both drives die, but I can't risk the second drive to a non-certified lab. I really trust the people on this list so hopefully you can point me to a real and non-bullshit lab that can really recover data. It would be nice to know if the lab can actually do #1 and certify my concerns and willing to testify in court because I want to press legal charges against the other lab if they in fact ripped me off and jeopardized my data. But if they can't I still need to recover the data! HELP! Thanks beforehand ! Announcing you'r thinking if suing the 1st rescuer, might make some people might be nervous in being 2nd rescuer. You could look at man fsdb Cheers, Julian -- Julian Stacey, BSD Unix Linux C Sys Eng Consultants Munich http://berklix.com Mail plain text; Not quoted-printable, Not HTML, Not base 64.

But if they can't I still need to recover the data! HELP! Thanks beforehand ! You could look at man fsdb FreeBSD offers a lot of versatile diagnostic and rescue tools, and surely fsdb is one of them. Others, provided by the base system, are fetch -rR device and also recoverdisk. In the ports collection you'll find tools like ddrescue, dd_rescue, ffs2recov, magicrescue, testdisk, scan_ffs, recoverjpeg, foremost and photorec. And finally there is The Sleuth Kit (with its tools fls, dls, ils and autopsy). Those tools keep you from spending money to companies who also use software (this one or something else). You could also waste money on recovery programs that won't work, so trying to use the tools mentioned would be the first step. I may give two additional advices in this context: 1. Do not work with the original disk. Make a dd copy and work with the image. 2. Read about what you're dealing with. This may consume some tome, but it really helps understanding what the problem is, and therefore helps finding a solution. This is the part of the story that I know from my own desaster. :-) But as soon as you encounter hardware problems with the disk, you should try to find a recovery lab you can trust. It can be a very complicated search, and the result will traditionally also be expensive. This is the case when they can do something you can't do on yourself (e. g. disasselmbling a disk, exchanging heads in a clean-room environment) - it's mostly a matter of dealing with hardware. -- Polytropon Magdeburg, Germany Happy FreeBSD user since 4.0 Andra moi ennepe, Mousa, ... ___ freebsd-questions@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-questions To unsubscribe, send any mail to freebsd-questions-unsubscr...@freebsd.org

Other lists exist too - Was Re: Hardware Recovery Company
For Alejandro Imass as original poster re. Hardware Recovery Company: FreebSD has a special mail list for file systeme it's name is f...@freebsd.org. (we also have hardware@ etc) For all, Questions@ started as a catch all fallback address for simple beginners questions from the newly installed, who didn't know / hadn't yet read http://www.freebsd.org/community/mailinglists.html http://www.freebsd.org/doc/en_US.ISO8859-1/books/handbook/eresources.html#ERESOURCES-MAIL to find where more exactly one might ask a question. Recently questions@ seems to be performing roughly the same purpose as hackers@ list, a random jamboree/ mellange of topics, which doesnt make much sense to me (where theyre posted, not the content of the questions), I think a lot of questions@ traffic would be better posted to hackers@ or other themed @freebsd.org lists.
