• How can I debug solutions in Visual Studio 2010 from a network share?

  - by alastairs

  I've recently got a new Mac laptop and am running VS2010 in a Parallels virtual machine. It's mostly working out well for me, but I'm having some problems with debugging specific project types, related to the fact that the projects are being accessed via a network share. Test projects don't run because the test runner can't load the tests' DLL. Web projects fail to run in the Visual Studio mini web server, throwing the following exception: 'An error occurred loading a configuration file: Failed to start monitoring changes to path\to\web.config'. I've spent the evening trawling the web with little luck on this. After reading these two posts, I tried out the usual CasPol changes, but then found this post from one of the early VS2010 betas indicating that CasPol is no longer needed/supported in .NET 4.0 and VS2010. The network share is accessible via both a mapped drive and the UNC path. The virtual machine runs its applications under the administrator account, which appears to have all the necessary permissions on the network share to create, read, write and delete files and folders. I say "appears to have" as I can't view the Security Properties of the appropriate folder via Explorer: the Security tab just isn't present. Has anyone managed to successfully load and debug web and test projects from a network share in VS2010?

• Performance experiences for running Windows 7 on a Thin-Client?

  - by Peter Bernier

  Has anyone else tried installing Windows 7 on thin-client hardware? I'd be very interested to hear about other people's experiences and what sort of hardware tweaks they had to do to get it to work. (Yes, I realize this is completely unsupported.. half the fun of playing with machines and beta/RC versions is trying out unsupported scenarios. :) ) I managed to get Windows 7 installed on a modified Wyse 9450 Thin-Client and while the performance isn't great, it is usable, particularly as an RDP workstation. Before installing 7, I added another 256Mb of ram (512 total), a 60G laptop hard-drive and a PCI videocard to the 9450 (this was in order to increase the supported screen resolution). I basically did this in order to see whether or not it was possible to get 7 installed on such minimal hardware, and see what the performance would be. For a 550Mhz processor, I was reasonably impressed. I've been using the machine for RDP for the last couple of days and it actually seems slightly snappier than the default Windows XP embedded install (although this is more likely the result of the extra hardware). I'll be running some more tests later on as I'm curious to see particularl whether the streaming video performance will improve. I'd love to hear about anyone's experiences getting 7 to work on extremely low-powered hardware. Particularly any sort of tweaks that you've discovered in order to increase performance..

• How to set CA cert file for LDAP backend server in smbpasswd configuration

  - by hayalci

  I am having a problem with smbpasswd, an LDAP backend server and SSL/TLS certificates. The client machine that I run smbpasswd on is a Debian Etch machine, and the Ldap server is Sun DS running on Solaris. All the following occurs on the client. When I disable SSL, by setting "ldap ssl = no" in smb.conf, the smbpasswd program works without errors. When I set "ldap ssl = start tls", the following messages are printed by smbpasswd and there is a long timeout period before any password is asked by it Failed to issue the StartTLS instruction: Connect error Connection to LDAP server failed for the 1 try! ..... long delay ..... New SMB password: Retype new SMB password: Failed to issue the StartTLS instruction: Connect error Connection to LDAP server failed for the 1 try! smbpasswd: /tmp/buildd/openldap2-2.1.30/libraries/liblber/io.c:702: ber_get_next: Assertion `0' failed. Aborted I conducted some tests with "ldapsearch -ZZ". It was not working at first, but after I added the TLS_CACERT line to /etc/ldap/ldap.conf, /etc/libnss-ldap.conf and /etc/pam_ldap.conf, it started working. So relevant TLS sections in all those files are: ssl start_tls tls_checkpeer no tls_cacertfile /path/to/ca-root.pem TLS_CACERT /path/to/ca-root.pem But the smbpasswd program continued giving the error. I tried creating /etc/smbldap-tools/smbldap.conf file with following content (after consulting debian docs for smbldap-tools package) But as I see, smbpasswd comes with samba-common package and does not use the configuration for smbldap-tools utilities. verify="optional" cafile="/path/to/ca-root.pem" My question is: How can I set which SSL CA Certificate is used by smbpasswd program ?

• How to bypass vpn talking to VMWare Guest?

  - by marc esher

  Greetings. Network/VPN n00b question here. I'm running VMWare Workstation with a Guest Windows 2003 Server. It has SQL Server 2000 installed. The sole purpose for this Guest is to house SQL Server... it needn't have internet access or access to any other resources on the network other than the host. When launch Check Point VPN software, the host routes through the company network before it connects to the guest ... i.e. it's no longer a direct connection. I assume this is just how things are supposed to work. However, what's happening is that the connection between my host and the SQL Server instance on the guest intermittently drops. It's not consistent, and some databases on the server will be responsive while others aren't. It appears that the databases with the most traffic on the guest (the ones I'm hitting with load tests) are the ones that become intermittently unresponsive. This problem only manifests when VPN is on; when it's off, I can pound away on this database with no troubles. Thanks for any advice!

• Monitoring multiple sites on a single server using OpsView

  - by Kev

  We have several web servers. On each of these servers there can be ~250 web sites. I need to add a HTTP check for each site on each server. Each site has a reserved host header that we know can always be resolved in the format of: w10000.hostchecks.mycompany.com w10020.hostchecks.mycompany.com w11992.hostchecks.mycompany.com ..and so on.. What I want is for there to be a master ping check on the web server's main IP address and then separate HTTP checks for each of the sites on the server. If the master ping test fails then I want the HTTP tests to cease until the master ping check goes OK. I had a stab at this and tried do the following: Create a parent host that does a ping check on the server's main ip address (e.g. server is named WEB0001). For each of the sites that reside on WEB0001: Create a separate Host with a Primary Hostname of wXXXXX.hostchecks.mycompany.com Make WEB0001 the parent host Add a monitor (HTTP check to a special url that is mapped into each site using a virtual directory: H- $HOSTADDRESS$ -u /__hostcheck/IsAlive.aspx -w 5 -c 10 -p 80 However I find that if I down the parent server (WEB0001) the http checks seem to continue. Am I going about this completely the wrong way?

• Why are my socks proxies slow

  - by vps_newcomer

  I have a linux vps, and i have tried a few socks proxy setups to test their performance: All tests were using speedtest.net The standard ssh tunnel proxy 0.8mbit/s download and 0.1-0.2mbit/s upload speeds dante-server proxy 1.3mbit/s download and 0.4-0.5mbit/s upload I am wondering why are these speeds so slow? Is anything shaping them? Is it just the nature of socks proxies? I know that the ssh tunnel has to do encryption and what not so that is why its slow, but i was surprised to see that the second setup was also quite slow. On the VPS i have received download speeds of 25MB/s per second (thats about 200mbit/s and upload speed of atleast 5MB/s (haven't got a good enough pipe to test anything faster). The other option i was going to try is to setup OpenVPN and see how that goes, however i need to find a good tutorial as it's fairly complicated to setup. So why is it so slow? How can i test to see where the bottleneck is? How can i make it faster :D

• Internal/External Moodle - DNS

  - by Chief17

  Network diagram: I have a moodle (a VLE) setup that I want to be internally and externally accessible. The green route on the diagram below is the route I would like the traffic to take when the user is inside the LAN, and the red route is seemingly what it does take. The website has a domain name (like most websites do). From the User PC, if I ping the domain name, I get the internal IP of the webserver (because of a hosts file entry), if I nslookup the domain name I also get the internal IP of the webserver (because of an A record on my DNS server). Running the same two commands on the webserver gives me the webservers external IP. (going well so far) If I use PHPs gethostbyname() on the moodle website and use domain name as a parameter (getting php/apache to resolve the hostname) it returns the exernal IP of the webserver (good news, DNS seems to be doing what I want it to). All things so far seem to be going well. The only thing that is confusing me and preventing the moodle single sign on from working is the fact that if I get moodle to show my IP address, it says that it is an external one (outside my NATting firewall) when it should show an internal IP. This is the issue, any ideas on how to go about resolving this? Any ideas on tests I can perform (I have also tried a tracert and the request goes directly to the webserver), anything? Thanks all!

• Where to get glib-config for Kubuntu?

  - by Carl Smotricz

  I'm trying to compile Midnight Commander on a KUbuntu 9.10 (Karmic) box with no root access. I've set up a directory under $HOME, downloaded the mc source package and various stuff required for building, such as autotools. I've unpacked the CONTENTS of all those packages into this working directory such that I have the usual ./usr, ./lib, ./etc hierarchy. I manage to get configure through a lot of tests, but I can't seem to fool it into finding glib. checking for glib-2.0... checking for glib-config... no checking for glib12-config... no checking for glib-config... no checking for GLIB - version >= 1.2.6... no *** The glib-config script installed by GLIB could not be found *** If GLIB was installed in PREFIX, make sure PREFIX/bin is in *** your path, or set the GLIB_CONFIG environment variable to the *** full path to glib-config. configure: error: Test for glib failed. GNU Midnight Commander requires glib 1.2.6 or above. My system has glib installed: /lib/libglib-2.0.so.0 /lib/libglib-2.0.so.0.2200.3 ... and I've also downloaded and unpacked the glib package into my working directory: libglib2.0-0_2.22.2-0ubuntu1_i386.deb libglib2.0-dev_2.22.2-0ubuntu1_i386.deb ... but still the elusive glib-config is nowhere to be found. It's not in any debian package for Karmic, either. So I'd appreciate any help getting over this hurdle. Please note, again, that I don't have root, so I can't just merrily apt-get stuff.

• Bash script dosn't open in terminal on reboot

  - by twigg

  Quick overview, I have created a script that reboots the laptop after x amount of time and x amount of cycles.

• Using Toshiba 22EL833 as PC display through HDMI input

  - by Oleg V. Volkov

  I had another Toshiba TV - 19SL738 - connected to this same PC and video card (GTX 8800) through DVI<-HDMI (DVI on PC side, HDMI on TV) before, that was working perfectly at it's native resolution 1360x768. Some time ago I had to change to 22EL833 and immediately faced problem with Windows 7 control panel and NVIDIA control panel both reporting native resolution for new TV as 1080i, 1920x1280, despite TV documentation saying that it have same 1360x768 as previous one. Practical tests confirmed that true native resolution is indeed 1360x768, because plugging in through DVI<-VGA and setting custom resolution through NVIDIA panel shown clear colors and crisp image, while setting anything different with either DVI<-VGA or DVI<-HDMI produced horribly distorted or squished images, with almost unreadable slim lines (as in letters, for example). Now, my problem is that there's no drivers for this TV and I'm unable to get good image while connecting it through DVI<-HDMI directly. The best I've achieved is editing EDID/driver manually, to persuade system that native resolution should be 1360x768, and while image became mostly clear, colors turned to some strange washed out effect, with pools of pure yellow, cyan and magenta there and there filling place of other colors. Gradients also became noticeably stripped as well. Somehow it looks like dithering gone bad and makes me suspect that image is still down/upscaled several times internally somewhere along the line. How can I connect this TV to DVI output of my video card to get best possible clear image, correct colors and correct native resolution?

• How to open semicolon delimited CSV-files in US-version of Excel

  - by Holgerwa

  When I double-click on a .csv file, it is opened in Excel. The csv-files have columns delimited with semicolons (not commas, but also a valid format). Using a German Windows/Excel setup, the opened file is displayed correctly, the columns are separated where the semicolons existed in the csv-file. But when I do the same on an (US-) English Windows/Excel setup, only one column is imported, showing the whole data including the semicolons in the first column. (I don't have an English setup available for tests, users have reported the behavior) I tried to change the list separator value in Windows regional settings, but that didn't change anything. What can I do to be able to double-click-open those CSV-files on an English setup? EDIT: It seems to be the best solution not to rely on CSV-files in this case. I was hoping that there is some formatting for CSV-files that makes it possible to use them internationally. The best solution seems that I'll switch to creating XLS-files. Thanks to all for your suggestions and helpful tips!

• Windows 7 VPN Error 619

  - by TravisPUK

  So I am running Windows 7 Enterprise. This morning I was able to VPN using the built in VPN (Connect to Work Network etc). I had to change my network's IP address range and now the VPN will not work. It just stalls on the Verifying user name and password... message. But then it returns the 619 error. Anybody know why changing my machine's IP address would cause this problem? Where should I be looking to try and fix this issue? I have tried this on a Windows XP machine that also had the IP address range change and this still connects fine using exactly the same connection details. EDIT The internal network range changed from 192.x.x.x to 10.x.x.x. This was done on the entire Active Directory. All machines are running fine and the Windows XP machine, that works going to the same client VPN mentioned above is on the same network. Both the XP and the Win 7 machines are using DHCP served by the Domain Controller. The client domain is not performing any IP range checks/restrictions. The VPN is outside the internal network, connection is being made via the Internet and not passing through any other machine, other than the normal domain machines, ie DNS etc. This is passing through a router and the router has the relevant VPN passthrough options configured. All internal machines are working correctly with other forms of VPN, ie Cisco, Sonic etc (these were tested on other machines, they are not installed on the Vista or Win7 machines). After further testing, this is occurring on all Win7 and Vista machines where they can no longer connect to the client VPN, however all XP machines can still connect fine. This has been tested on three Vista, two Win7 and five XP machines. All machines are on DHCP and tests have been done with both the firewalls turned on and off, as well as with fixed IPs being used. Thanks Travis

• KVM and JBoss Java Application Server

  - by Jason

  We have a large Xen deployment running on both RHEL and CentOS and have recently started looking at KVM since this is where it looks like the future of VM's are on Linux. We can load the server and get everything running without an issue. However when we load up a new one with JBoss (4.2 Community edition, Sun JDK 6) and load a large EAR the server goes a little crazy. The %sy will jump to 80-99% and just hang for large periods of time we see a similar jump in %us on the host machine. We though at first this might be I/O as it seems to happen at start of JBoss but then would "cool down" after everything got loaded. We did some tests by extracting some large tar.gz files and using jar -xvf on the ear but could not re-create. Then we starting thinking this might be some type of memory access issues. We loaded a c-program that would generate a lot of memory activity and sure enough we saw the spikes again. Not as high mind you but we did see it jump. We then wrote a small java program to do the same thing and sure enough we saw it jump again. Any thoughts on what might be causing this? Is this just the way KVM works? As a side note we do NOT see this behavior on any other setup. Xen, VMWare and/or native iron. The system does seem a bit slower than our Xen / VMware ones.

• Proper way to use hiera with puppetlabs-spec-helper?

  - by Lee Lowder

  I am trying to write some rspec tests for my modules. Most of them now use hiera. I have a .fixures.yml: fixtures: repositories: stdlib: https://github.com/puppetlabs/puppetlabs-stdlib.git hiera-puppet: https://github.com/puppetlabs/hiera-puppet.git symlinks: mongodb: "#{source_dir}" and a spec/classes/mongodb_spec.rb: require 'spec_helper' describe 'mongodb', :type => 'class' do context "On an Ubuntu install, admin and single user" do let :facts do { :osfamily => 'Debian', :operatingsystem => 'Ubuntu', :operatingsystemrelease => '12.04' } end it { should contain_user('XXXX').with( { 'uid' => '***' } ) should contain_group('XXXX').with( { 'gid' => '***' } ) should contain_package('mongodb').with( { 'name' => 'mongodb' } ) should contain_service('mongodb').with( { 'name' => 'mongodb' } ) } end end but when I run the spec test, I get: # rake spec /usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color F Failures: 1) mongodb On an Ubuntu install, admin and single user Failure/Error: should contain_user('XXXX').with( { 'uid' => '***' } ) LoadError: no such file to load -- hiera_puppet # ./spec/fixtures/modules/hiera-puppet/lib/puppet/parser/functions/hiera.rb:3:in `function_hiera' # ./spec/classes/mongodb_spec.rb:15 Finished in 0.05415 seconds 1 example, 1 failure Failed examples: rspec ./spec/classes/mongodb_spec.rb:14 # mongodb On an Ubuntu install, admin and single user rake aborted! /usr/bin/ruby1.8 -S rspec spec/classes/mongodb_spec.rb --color failed Tasks: TOP => spec_standalone (See full trace by running task with --trace) Module spec testing is relatively new, as is hiera. So far I have been unable to find any suitable solutions. (the back and forth on puppet-dev was interesting, but not helpful). What changes do I need to make to get this to work? Installing puppet from a gem and hacking on rubylib isn't a viable solution due to corporate policy. I am using Ubuntu 12.04 LTS + Puppet 2.7.17 + hiera 0.3.0.

• Strange behaviour when creating/deleting subdomains

  - by Saif Bechan

  This can be a DNS cache issue from my local machine, but I am not sure. This is what happens. I have a domain that does not use wildcard subdomains, so they have to be created. Without creating the domain, and I point my browser to test.domain.com, I get a page server not found. Now when I create the subdomain, I keep getting the same problem. Now when I first create the domain, without ever visiting the page, I get the normal page, but now when I delete the subdomain, it never goes away. Can this be a DNS cache issue, I am working on a shared environment, maybe the router has a cache but I doubt that. Can this have something to do with my setup. I have tried to use the Google DNS hosting, but this gives me the same results. I have also tried some tools that clear my local DNS cache, they were some add-ons for FireFox. Anyone have any ideas what can be the problem. Are there any tests I can do to see if there is some kind of cache between me and the server.

• Hudson deploy specific git revision

  - by brad

  I'm using hudson to auto-deploy my Rails app to heroku. In my main build job I pull from a Git repo (hosted using gitosis on the same machine), master branch with the following: URL of repository: /home/git/repositories/my_app.git Name of repository: origin Refspec: +refs/heads/master:refs/remotes/origin/master Branches to build: master Then, assuming all tests pass, I want to kick off a new build that is the deploy to Heroku. I can't however figure out how to get that deploy build to checkout the particular revision that this build was using. I understand there's a parameterized trigger plugin that would allow me to pass this revision number, but I don't know how I can tell hudson to checkout this particular revision on the deploy build. I'm pretty sure this just has to do with my limited knowledge of git, but where in the hudson git config's is there an option to checkout a particular revision? Otherwise, I could have many commits happen whilst a build is happening, and when it kicks off a deploy build, that deploy build would just check out the HEAD of the branch, which may not be the same as the code that was pushed that triggered this build. I don't fully understand why I have a refspec in Hudson, then also specify a branch to build, I thought this was the same thing. Can refspec somehow specify the revision number? How would this be referenced if it was passed through with the parameterized trigger plugin? (I've never used that plugin, but someone else recommended it as a way to pass in vars to a new build, if there's another way I'm all ears)

• Sony PMB causing failure to load Windows 7 Pro 64-bit normally or even Safe Mode

  - by Wesley

  After installing Sony's Picture Motion Browser on my desktop with Windows 7 Pro x64, it always goes to Startup Repair due to Windows 7 failing to start. This always happens after I try to install it. I've installed with all unnecessary programs closed and all disk drives and unnecessary usb ports empty. I don't exactly know what is causing the problem. Any ideas? My desktop is an HP m8530f. http://h10025.www1.hp.com/ewfrf/wc/document?docname=c01469325&tmp_task=prodinfoCategory&lc=en&dlc=en&cc=us&product=3740333&lang=en Only upgrades are an HD4350 and a 500W PSU. EDIT: Windows 7 cannot start now. I'm currently running diagnostic tests from the BIOS. EDIT: Here are the problem details. Problem Signature: Problem Event Name: StartupRepairOffline Problem Signature 01: 6.1.7600.16385 Problem Signature 02: 6.1.7600.16385 Problem Signature 03: unknown Problem Signature 04: 21201022 Problem Signature 05: AutoFailover Problem Signature 06: 8 Problem Signature 07: CorruptFile OS Version: 6.1.7600.2.0.0.256.1 Local ID: 1033 CONCLUSION: So, I think Sony PMB may have caused some sort of corruption in the system files. So if you have Windows 7 and plan on installing Sony PMB, find a Vista or XP machine to install on.

• Testing for disk write

  - by Montecristo

  I'm writing an application for storing lots of images (size <5MB) on an ext3 filesystem, this is what I have for now. After some searching here on serverfault I have decided for a structure of directories like this: 000/000/000000001.jpg ... 236/519/236519107.jpg This structure will allow me to save up to 1'000'000'000 images as I'll store a max of 1'000 images in each leaf. I've created it, from a theoretical point of view seems ok to me (though I've no experience on this), but I want to find out what will happen when there will be directories full of files in there. A question about creating this structure: is it better to create it all in one go (takes approx 50 minutes on my pc) or should I create directories as they are needed? From a developer point of view I think the first option is better (no extra waiting time for the user), but from a sysadmin point of view, is this ok? I've thought I could do as if the filesystem is already under the running application, I'll make a script that will save images as fast as it can, monitoring things as follows: how much time does it take for an image to be saved when there is no or little space used? how does this change when the space starts to be used up? how much time does it take for an image to be read from a random leaf? Does this change a lot when there are lots of files? Does launching this command sync; echo 3 | sudo tee /proc/sys/vm/drop_caches has any sense at all? Is this the only thing I have to do to have a clean start if I want to start over again with my tests? Do you have any suggestions or corrections?

• finding the best network latency between two countries

  - by Yoav Aner

  I know there are many tools to test for bandwidth and latency, but they all rely on having at least one host from which you can run those tests. I wonder whether there's an online source or some other way to guestimate the latency or speed between two countries (in general). For example, would a customer in Japan get lower latency if the server is located in Singapore or Australia? Is a user in India likely to get higher download speed from a server in the UK or in the US? Are there any online resources or some clever ways to answer those questions with a reasonable degree of accuracy? [UPDATE]: Thanks for the great suggestions from Raffael Luthiger. I didn't know about those looking glass servers. The submarine cable maps were also really cool to discover (Thanks to Jesper Mortensen). Also seems really wise if I could ask those network professional in the area for their experience, but obviously I don't have access to those. At least some of them are on SF :) However, I'm still a little unsure how to combine those resources to give me some measurements. This is the information I have: Two countries (A,B). I do have IP addresses of customers in country A (I can obtain those from the web server log files for example). Presumably I can find some looking glass servers in country B and run a trace to those IPs. What's the best measurements to use? Are there any scripts that help automate at least some of this process?

• Feasibility of Windows Server 2008 DFS replication over WAN link

  - by CesarGon

  We have just set up a WAN link that connects two buildings in our organisation. The link is provided by a 100-Mbps point to point line. We have a Windows Server 2008 R2 domain controller on each side of the link. Now we are planning to set up DFS for file services across the organisation. The estimated data volume is over 2 TB, and will grow at approximately 20% annually. My idea is to set up a file server in each building and install DFS so that all the contents stay replicated over the 100-Mbps link. I hope that this will ensure that any user will be directed to the closest (and fastest) server when requesting a file from the DFS folders. My concern is whether a 100-Mbps WAN link is good enough to guarantee DFS replication. I've no experience with DFS, so any solid advice is welcome. The line is reliable (i.e. it doesn't crash often) and our data transfer tests show that a 5 MB/sec transfer rate is easily achieved. This is approximately 40% of the nominal bandwidth. I am also concerned about the latency. I mean, how long will users need to wait to see one change on one side of the link after the change has been made on the other side. My questions are: Is this link between networks a reliable infrastructure on which to set up DFS replication? What latency times would be typical (seconds, minutes, hours, days)? Would you recommend that we go for DFS in this scenario, or is there a better alternative? Many thanks.

• I think installing PostFix solved my problem, but it seemed *too* easy

  - by Joel Marcey

  Hi, This is a followup to a serverfault post I made a while ago: http://serverfault.com/questions/21633/how-do-i-target-a-different-mail-server-depending-on-domain-with-exim (More context here too: http://forum.slicehost.com/comments.php?DiscussionID=3806 ) I have a slice/VPS at Slicehost. I basically decided to scrap exim (i.e., purge it), and start anew with my email infrastructure. In case you didn't read any of the above threads, basically my goal was to have a send only mail infrastructure that relays all outgoing email to Google Apps. I also wanted to where email from domain1 (a Wordpress installation) would show it coming from domain1.com and email from domain2 (a normal website) would show it coming from domain2.com. So I decided to give PostFix a try. I literally followed the surprisingly simple instructions here: http://sudhanshuraheja.com/2009/02/slicehost-setup-outgoing-mail-google-apps-postfix/ And voila, all seems to be working as I expected. My email tests show email coming from the proper locations (either domain1 or domain2 depending on where the emails were sent from). But this all seemed too simple to me. So simple, in fact, that I feel that something is amiss. When I installed PostFix according to the instructions in the post above and it worked, I was surprised that I didn't have to specify an SMTP server, a port number, any authentication credentials, etc. My slice is set up such that I have MX records for Google Apps (e.g., ASPMX.L.GOOGLE.COM.) in my DNS settings, but I am not sure if that is why it is working. My email infrastructure knowledge is admittedly limited, but with this am I suspect to: Spammers using my email infrastructure? My emails going to people as spam? Something else sinister? I have actually stopped running PostFix until I understand this better. Thanks!

• ZFS with L2ARC (SSD) slower for random seeks than without L2ARC

  - by Florian Kruse

  I am currently testing ZFS (Opensolaris 2009.06) in an older fileserver to evaluate its use for our needs. Our current setup is as follows: Dual core (2,4 GHz) with 4 GB RAM 3x SATA controller with 11 HDDs (250 GB) and one SSD (OCZ Vertex 2 100 GB) We want to evaluate the use of a L2ARC, so the current ZPOOL is: $ zpool status pool: tank state: ONLINE scrub: none requested config: NAME STATE READ WRITE CKSUM afstank ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c11t0d0 ONLINE 0 0 0 c11t1d0 ONLINE 0 0 0 c11t2d0 ONLINE 0 0 0 c11t3d0 ONLINE 0 0 0 raidz1 ONLINE 0 0 0 c13t0d0 ONLINE 0 0 0 c13t1d0 ONLINE 0 0 0 c13t2d0 ONLINE 0 0 0 c13t3d0 ONLINE 0 0 0 cache c14t3d0 ONLINE 0 0 0 where c14t3d0 is the SSD (of course). We run IO tests with bonnie++ 1.03d, size is set to 200 GB (-s 200g) so that the test sample will never be completely in ARC/L2ARC. The results without SSD are (average values over several runs which show no differences) write_chr write_blk rewrite read_chr read_blk random seeks 101.998 kB/s 214.258 kB/s 96.673 kB/s 77.702 kB/s 254.695 kB/s 900 /s With SSD it becomes interesting. My assumption was that the results should be in worst case at least the same. While write/read/rewrite rates are not different, the random seek rate differs significantly between individual bonnie++ runs (between 188 /s and 1333 /s so far), average is 548 +- 200 /s, so below the value w/o SSD. So, my questions are mainly: Why do the random seek rates differ so much? If the seeks are really random, they should not differ much (my assumption). So, even if the SSD is impairing the performance it should be the same in each bonnie++ run. Why is the random seek performance worse in most of the bonnie++ runs? I would assume that some part of the bonnie++ data is in the L2ARC and random seeks on this data performs better while random seeks on other data just performs similarly like before.

• Splitting build cross the network?

  - by Dandikas

  Is there a known solution for splitting build process cross the network machines? Use case: We are an average software development company. We own around 50 development workstations (Quad Core 2.66Ghz, 4 GB ram, 200 GB raid). No need to tell that at any single moment not every machine is loaded to the max. There are 5 to 15 projects running simultaneously at any single moment. Obviously all of them are continuously build on server, than deployed to proper environment. Single project build is taking from 3 to 15 minutes. The problem: Whenever we build 5 projects in a row the last project is going to be ready after around 25 - 50 minutes. Building in parallel does not solve the problem (build is only a part of the game, than you need to deploy, run tests etc.) YES the correct solution is to add another build server, but "That involves buying new Expensive hardware, and we already spent a lot!". Yea, right(damn them)! Anyway. What about splitting build among developers workstation? Lets say whenever we need to build project "A" we check 5 workstations and start build on all that are not overloaded. The build can be canceled by a developer if he really needs all the power of his machine as long as there is at least 1 machine that is still building. After build is finished deployment can be performed to a proper environment (hosted on some server, not on workstation :) ). The bigger the company the more this makes sense to me. Anyone tried something like this? Are there any good practices? Any helpful software?

• Stop the constant random reboots of my GIGABYTE GA-B75M-D3V

  - by Frederic

  I've got some issues with a new system. It's rebooting constantly. The system consists of a: brand new: Gigabyte GA-B75M-D3V with F9 BIOS (latest) Intel Core i5-3470 Ivy Bridge 2x 8GB G.SKILL Ripjaws 1600MHz memory (mem-tested x-86) coming from a stable system: Creative Soundcard X-FI Titanium Asus Radeon HD4850 OCZ Vertex 3 120G SSD Sata 3 Hard disk 1TB Sata 2 ASUS Blu-ray Drive PSU 400w Connected peripherals : Toshiba tv (displayport on dvi of MB or HD4850) Wired mouse, wireless keyboard (logitech) Bluetooth usb key Azio main problem : it's not possible to read the errors from the MB. nothing on the manual neither on internet. At the beginning, I received a MB with graphic problems and the problem of rebooting. I RMA'd it. The new one doesn't have any graphic problems. but it's still constantly rebooting. I removed everything except the HD, the sound-card, the blu-ray drive and the wireless keyboard. It's still unexpectdly rebooting. I'm running a test with just the motherboard and the HD. I will update this text after the test. I've got some questions : Somebody have an idea of a test? The PSU could cause that problem? I used it a lot of years with the stable system. Update 1: BTW, if anyone has the same problem, the manual won't say it but you'll need to reset the bios between two tests (the screwdriver on the two pins) if you suspect a problem of compatibility .
