Well, the glue record will be ``above the cut'': if .au delegates alicesprings.au, it's the .au nameserver that provides the A record for ns1.alicesprings.au; but, yes. ___ 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
zfs performance issues with iscsi (istgt)
After scratching my head for a few weeks, I've decided to ask for some help. First, I've got two machines connected by gigabit ethernet, network performance is not a problem as I am able to substantially saturate the wire when not using iscsi [say iperf] or ftp. Both systems are 8.1-RELENG. They are both multi-core, 8G of RAM. Symptoms: When doing writes (size relatively independent) from a client to a server via iSCSI I seem to be hitting a wall between 18-26MB/s of write. This can be repeated continuously whether doing a newfs on a 2TB iscsi volume or doing a dd from /dev/zero to the iscsi target. I haven't compared read performance. What originally put me on to this was watching the newfs *fly* across the screen, and then hang for several seconds, and then *fly* again, and then pause. This looked like a write-delay problem, so I tweaked txgwrite values and/or the synctime values. This showed some improvements (iostat showed something closer to continuous write performance to the server but there was still a delay whether the write_limit was 384MB all the way up to 4GB. This tells me the spindles weren't holding the throughput back. The iostat size was never much beyond 20-26MB/s, peaks were frequently two-three times that, but then it would be 1MB/s for a few seconds which would bring us back to this average). CPU and network load were never the limiting factor, nor did the spindles ever get above 20-30% busy. So I added two USB keys that write at around 30-40MB/s, and mirrored them as a ZIL log. iostat verifies they are being used, but not continuously, it seems that the txgwrite value applies to writing to the ZIL. I also tried turning off the ZIL log and saw no particular performance increase (or decrease). When newfs (which jumps around a lot more than dd) the performance throughput does not change much at all. Even at 26K-40K pps, interrupt loads and such are not problematic, turning on polling does not change the performance appreciably. The server is a RAIDZ2 of 15 drives @ 2TB each. So *write* throughput should be pretty fast sequentially (i.e. the dd case), but it is returning identically. This server does nothing much but istgt -- tried NCQ values from 255 down to 32 to no improvement. Even though network performance was not showing a particular limit, I *did* get from 18MB/s to 26MB/s by tweaking tcp sendbuf* and tcp send* values way beyond reason even though the TCP throughput hadn't been a problem in non iscsi operations. So whatever i'm doing is not addressing the particular problem. The drives have plenty of available I/O, but instead of using it, or the RAM in the system, or the ZIL in the system, it seems largely idle, pegs the system with continuous (but not max speed) writes and halts the network transfers, and then continues on its way. Even if its a threading issue (i.e. we are single threading) there should be some way to make this behave like a normal system considering how much RAM, SSD, and other resources I'm trying to through at this thing. For example, after the buffer starts to empty, additional writes from the client should be accepted and NCQ should help reorder to process them in an efficient fashion, etc, etc. istgt settings: istgt version 0.3 istgt extra version 20100707 MaxSessions 32 MaxConnections 32 FirstBurstLength 65536 MaxBurstLength 262144 MaxRecvDataSegmentLength 262144 Local benchmarks like dd if=/dev/zero of=/tank/dump bs=1M count=12000 returns like 200MB/s. 12582912000 bytes transferred in 61.140903 secs (205801867 bytes/sec), and show continuous (as expected) writes to the spindles. (200MB/s is pretty close to the max I/O speed we can expect given the port the controller is in and RAID overhead, etc with 7200 RPM drives, at 5900 RPM the number is about 80MB/s). If this is an istgt problem, is there a way to get reasonable performance out of it? I know I'm not losing my mind here, so if someone has tackled this particular problem (or its sort), please chime in and let me know what tunable I'm missing. :) Thanks very much, in advance, DJ ___ 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 detail of this approximation heavily depends on the pseudo-rng you are using, as does its correctness Perhaps it would be useful in a PRNG test suite?

If abs(drand48()) always exceeded (0.5 * sqrt(2.0)), a*a + b*b would always exceed 1.0, thus counter would never be incremented and pi would be reported as zero. That'd be one pretty sad PRNG :) but testing variance of the above algorithm's result to best known double pi is likely a useful test. And while a square enclosing a circle, it's hardly squaring the circle: http://en.wikipedia.org/wiki/Squaring_the_circle .. but an interesting read nonetheless for unrequited seekers of pi-foo :) cheers, Ian ___ 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

Not fully. The strength of the command line is (1st) that things you learned can easily be transferred to new topics, and (2nd) you can conclude from what you already know. GUI usually is a discover new things each time; as a good example I may point you to famous office suits that tend to re-arrange their functionality with each release. Well-designed UIs allow you to easily discover how to do it without resorting to the Help file - and since people tend to have good visual memories they can remember it better than a string of characters. Okay, you're comparing visual memory (looks like) to the use of language (a foreign one, admitted), which is a basic cultural means (the use of a language). Following your argument, it is obvious that many GUI applications are NOT well-designed, as they force their users to continuously re-discover and re-learn things. Additionally, GUI prohibits giving clear instructions. Those that can be copied+pased are out of scope, of course. Instructions look like childrens books - full of pictures. This is logical as there is no benefit in DESCRIBING those pictures - would be too much text, text scares users. Learning CLI is like learning a language: If you're once familiar with the elements of the language (its vocabulary, its syntax, its use), you can express ANYTHING with it. With GUI, you're just free to choose from a predefined and LIMITED set of options. You can choose from ready-made sentences, but you can't express your own statements. The CLI approach leads to a continuous growth of knowledge (that is portable), while the GUI approach often just leads into stagnation. A real benefit of GUI, as I can admit without any problems, is that people judge by first sight. This is a visual impression that has nothing to do with any knowledge, it's just like saying I like Da Vinci's 'Mona Lisa', but I don't like Edvard Munch's 'Scream'. Keep in mind this is a VALID statement that does not require any knowledge to be formed. By well-designed GUI, products can easily be placed on markets. Advertising based on visual impression works much better for masses (!) than product presentation based on actual features (that require knowledge to form a statement about them). A good example of this is Subversion tagging/branching: in Windows I can use the menu option TortoiseSVN - branch/tag... to create a branch and have it done in a minute. Using the command-line I'd have to spend time reading up on the commandline parameters to achieve the same thing, since it's something I only do about once a year or so. In a different Subversion GUI client, this functionality may be found at a completely different place. CLI applications usually have more things in common than GUI applications. That said, you can easily see why generic UNIX knowledge, no matter if achieved on BSD, Solaris, Linux or AIX, is portable, while GUI knowledge, achieved in a Windows of version N, is not portable to version N+1, as it is outdated. There even is no generic knowledge, one may assume. Let me ensure you that I'm NOT against GUI generically.

But as options become more complex, either the GUI must also become more complex or you reach the tipping point where the complexity warrants the use of language instead of gestures. This is a valid point. There was a statement - no idea who said or wrote that - expressing it well, and I'm sure I'm mapping it into context right now: GUI makes simple tasks simpler. It also makes complex tasks impossible. As a GUI is only choosing from a predefined subset of options, complex tasks make the corresponding GUI more complex. This may proceed until the GUI isn't usable anymore. At this point, it gets abandoned, naturally. According to your point gestures vs. languages: Consider being a child. When you didn't have the ability to use language, you did point to objects and made a sound, ga! or dah! or whatever. Later on, when you learned to use the language, it started at not being perfect, but you kept learning it and then used it to express wishes, thoughts, needs. In this way, you did abandon pointing and dah!. Why? It should have worked continuously - e. g. there was no obvious reason others would stop interacting with you at that non-language level. But that is how intellectual development works. It is an evolutionary consideration. Applying this to GUI and CLI concepts, GUI, pointing and clicking, resembles the childish way of nonverbal communication. CLI, forming statements using a language, is like verbal communication. The STRENGTH OF GUI (yes, I'm really saying that) is to aid using language elements, CLI. Arranging windows, presenting information, displaying structures, managing things. GUI alone, with no functional substance behind it, is useless.

Sorry - I didn't mean to imply that it was worthless, just that I believe the efficiency works the other way sometimes.

Hmm. I wonder which I should choose. Why choose? Combine efficiently! :-) I select and middle click to paste quite a lot. This is much better than the ^C/^V approach, as seems to be supported by every application, no matter which echosystem it comes from. Every? Erm... no. Did I recently talk about bloat? About reduction of functionality? I did. Allow me to elaborate on an example. It's a Gtk version 2 example. Let's say it's X-Chat 2. It's the channel selection dialog on startup. In version 1 (using Gtk), you could select an item from a list using doubleclick on that item. In version 2, you are forced to select the item with one click, move the mouse to a button and then click that. First: t(2cl) t(1cl + move + 1cl). Then what happens if you still doubleclick on a list item? It becomes an input field. Well, hmmm... could be useful. Let's put some text in there from another program window. Oops, the window lost focus, and the input field got a list item again! Okay, not a big deal, we'll be back soon. After selecting the text (e. g. in a browser, a text editor, whatever), again clicking the list item, it gets an input field. Middle mouse... erm, middle mouse... middle mouse... why doesn't this work? Buffer empty? Check in an xterm... no, text is in the buffer. WHAT'S WRONG?! So what did Gtk 2 achieve here? 1. increased time for selection 2. inability to use copy / paste 3. - the most annoying one - FORCING to type (even if this just means ^C/^V) I really can't stand it when BASIC functionality disappears with NO understandable effect. Fatter libraries, longer time until program is up, and then everything gets slower and much less productive -- that must be bloat. I'm not opposed to use of the GUI per se; I just use TUIs much more often, because I use them for tasks that I perform an awful lot if they happen to benefit (in terms of efficiency and productivity) by the use of a TUI. When they don't, I use a GUI instead. That exactly is an educated standpoint - use whatever tool is the best - instead of insisting that the tool HAS TO BE a GUI tool, like saying: But I WANT the screwdriver to be a drill! I've ALWAYS used screwdrivers as drills, and EVERYONE uses screwdrivers as drills! Oh, and it should work as a hammer, too. By the way, TUI (text user interface) doesn't imply that is has to be CLI (command line interface). A famous example from by daily use is the Midnight Commander, a file manager that DOES IT CORRECTLY. As many (most?) things you do is a source-target- opertion (copying, moving, symlinking), the two-panel mode is the ideal solution. Good keyboard controls and the use of the very useful function keys is one of its strengths. Still, it does operate in text mode (defaults to 80x25, but can be used at any window size), so you can easily work with it over a serial line or SSH. GUI usually means abstraction. Abstraction adds layers, in this way or another. At some point, this is good as you can fit things together, but at some point, it gets unusable because you can't address the things directly you NEED to address directly. I wouldn't be willing to waste the time on little inefficiencies every single time I did *anything* with Subversion just for the dubious benefit of a one-time efficiency benefit once a year because I didn't remember off the top of my head how to branch, though. From computer science, just see what O notation means, and see that constant compexity is traditionally better than linear complexity: O(1) O(n). :-) I suppose your mileage may vary, though. It always depends on individual preferences, talents, knowledge and experience. I'm always impressed by people who are more advanced than me, who use minimalistic environments and can work faster, more productive, more relaxed.

Hi, We have a problem with a few of our users. And I'm a bit speechless since I understood what are our commercials doing... Whatever... We are providing a pre-configured FreeBSD distribution, for videosurveillance prupose. It seems the machines sold with our distribution may come with at max 44TB RAID space. And more likely, all the RAID space is allocated in an only partition (UFS). Note that these servers includes only 2GB of RAM. So, since a few, custommers are calling, telling us that there's a problem with their RAID space. As far as I know, all these users are running our FreeBSD-6.2 based version. They try to run fsck, wait and eventually fsck stops, saying it can't do anything (I haven't the exact error message...). My boss came, and asked me wether I think upgrading these custommers to our 7.2 based version would fix that. I told him I'm not up to date about that kind of info. But more likely, UFS/fsck worked fine in 6.2, no way there's such a big change in 7 branch. In my opinion, the only chance to get back the data would be to plug an additional drive, make a huge swap file...

That's exactly what you're talking about. I don't see why you have to pretend I didn't mention it, and try to paint the efficiencies on the other side of the trade-off as worthless in your response. I thought my original description of the trade-off was pretty well balanced, despite the fact I have a preference for one side over the other where most tasks are concerned. Sorry - I didn't mean to imply that it was worthless, just that I believe the efficiency works the other way sometimes. For example I did Linux development for a while earlier this year and found it to be extremely inefficient compared to working in Windows, due to overuse of terminals and command-line operation - and I grew up running BBC BASIC and have been using FreeBSD for many years. I love having the command-line available and indeed often develop software using just an xterm but I do think a well-designed GUI can increase productivity by bringing things together that would otherwise be separate. You probably found it inefficient because you did not bother to gain sufficient familiarity with it to enjoy the efficiencies it provided. Seriously. In my experience, development on MS Windows with clicky GUI tools like Visual Studio only seems more efficient when doing things that are very well-worn paths to very uninteresting destinations for people who have never bothered to learn a better way. A well-configured Vim provides a substantial efficiency boost for the competent user that dwarfs the dubious benefits of things like Intellisense, for instance. When developing software in a Unix(-like) environment, I typically have *several* terminals open, running different programs. For Ruby, for instance, I might have a Vim terminal, an irb terminal, and a test suite terminal, possibly including a second buffer in the test suite terminal for running the program separately when appropriate -- rather than just using just an xterm -- and it works better than any Visual Studio setup I've encountered on MS Windows for similar development. In fact, there are whole classes of software that are effectively impossible to develop effectively on MS Windows; it doesn't get much more inefficient than that. Sometimes a GUI that brings things together can help. You're right about that. Unfortunately, such GUIs usually shoot themselves in the foot by not just bringing things together, but actually replacing them so that the benefits of the separate things are lost, resulting in a net loss of productivity enhancement.

how to trace /dev/gpt/label to adaX to conroller?

A well-configured Vim provides a substantial efficiency boost for the competent user that dwarfs the dubious benefits of things like Intellisense, for instance. If you're clicking lots you're doing something wrong :) I think the key thing is well-configured. I've found that far too many users have poorly-configured systems that require them to drop to a terminal and type commands when they want to run builds, find where something's defined etc. That involves find, grep etc. which is far less efficient than clicking the (the built-in) Go to definition command or hitting the shortcut key within an IDE; I know the same can be done in vim by defining macros for building, running ctags/cscope etc. I'm not convinced about IntelliSense either, really. At one job I found people dependended totally on it, and complained when it broke. I find I use it as a productivity enhancement when I know roughly what parameters a function takes but can't remember the ordering - it's more useful when you have a huge framework like Java or .NET, or an overly complex API like WinAPI (e.g. CreateFile). Too many people _do_ depend on it though, which I think introduces an inefficiency in their work. In terms of efficient use of Visual Studio it takes time to learn and become a competent user: for example I hardly ever use the menus since they're so slow to access. I hardly leave the keyboard and hate watching people waste time for example clicking Build, moving to the Build Solution entry and clicking when I could have done it in a fraction of the time using Ctrl-Shift-B. I know vim, with suitable plugins and macros, can be made to be more efficient than Visual Studio since it doesn't require ever using the mouse but the upfront investment in time to learn and configure it is something I've never done, mainly because I've always had more important things to learn and the inefficiencies of GUI editors don't really worry me. -- Bruce Cran ___ 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

But if you want to make _really sure_ that a spinning disk hasn't mangled the data you should: - Calculate a checksum of a data block in memory. - Write the data block to disk (with write caching disabled to make as sure as possible that the data is on disk when the write finishes. That is a _huge_ performance penalty) - Read the data back from disk (and not from the cache!) and compare with the original checksum. - If the read checksum control fails, mark the block as bad and repeat at another location Personally I don't see how this is going to be fast without compromising on correctness. If you keep the disk write cache enabled to the best of my knowledge there is no way for the OS to know for sure that the data is actually on the plates, so the read-back and comparison stage might not mean anything.

Re: apache13 to apache22
On Mon, Nov 08, 2010 at 02:18:19PM -0500, Fbsd8 wrote: As I do a complete fresh install of 8.1 I saw that apache13 is no longer being supported, so thought this is the time I will move to apache22. Now everything went real easy until testing my websites. In apache13 the .css (style sheet) calls for a blue background. The .css file is in the same directory as the html files making up the website. In apache13 I got the blue background but in apache22 I get a white background. I checked the apache22 htppd.config file for any info on css but found none. Are .css (style sheet) handled differently in apache22? AFAIK they're not. It sounds like the stylesheet isn't being served up (white background is default). Examine the apache error log. By default it's in /var/log. Also look in the regular apache log and it could be the stylesheet is getting a 404. Is server root the same in httpd.conf for 2.2 as it is for 1.3? Could be the cause of the problem. 2.2 uses a different root by default IIRC.

So please some one help me for the same. /student/sweety/gaussiandata/*1249624064640*/input Could you, in your script do something like: cd /Path_to_Data_Root find . -name *.chk -print -prune -exec rm -rf {} \; If you really want to delete all the .chk files extension files at a time find path -name '*.chk' -print -prune -exec rm -rf {} + \; -- Eitan Adler ___ 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

As a non-programmer I would not even try but perhaps someone with better skills already did? FWIW MirBSD seems to have a port of the keyd. FreeBSD doesn't have a linux-style blocking /dev/random, so it couldn't be used in quite the same way as in other OS. Personally I think the key demographic for this is people with more money than sense. Could you please elaborate a bit over this? ___ 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
