  • Linux Has Become Very Slow Dealing With Large Data

    - by Kohjah Breese
    Last year I bought a computer, for around $1,800, so it is relatively high-end. When I first got it I was particularly pleased at how quick it dealt with large MySQL queries, imports and exports. But somewhere along the way something has gone wrong and I am not sure how to diagnose the problem. Any job that involves processing large amounts of data, e.g. gzipping file c. 1GB+, UPDATEs on large MySQL tables etc. have become very slow. I just performed an intensive alter statement on a 240,000,000 row table on a remote server, which is lower spec. This took about 10 minutes. However, performing the same query on a 167,000,000 row table on my computer went fine until it hit 860MB. Now it is only writing about 1MB every 15 seconds. Does anyone have any advice as to debugging what the issue is? I am using LinuxMint (based on Ubuntu 12.04.) The home partition is encrypted, which really slows down gzip. I have noticed the swap is barely used, but am not sure if that is because there is more than enough RAM. The filesystem is ext4. The MySQL server is on a separate hard drive, but it was fine when I first installed it. Other than the above issues, there are no other problems with it. I am going to install a fresh Ubuntu on the 4th hard drive to see if that is any different.

  • Why am I getting kicked from an IRC channel in one OS (xp) but not in the other OS (7)? [closed]

    - by moshe
    I got kicked from an IRC channel. I have Windows XP and now if I'm trying to get into this specific channel, I get inside but I get immediately kicked out. I can come in again, and again get kicked out. It seems this is done automatically. Now I have also installed, on another hard drive in the same computer Windows 7. On Windows7 I can get into this same channel and never kicked out! It's the same computer, but different operating system(separate Hard Drives). How can it be? Is the KICK command bias towards the operating system I got KICKed in? Please explain to me how this thing is happening. PS: I forgot to mention that it doesn't matter if i change my IP or my nickname, I continue to kicked out from this channel. Again, in windows 7 I can get in without a problem. another thing that is good to mention is that i got kicked out when i was using windows XP, and not windows 7. i think that it could happened also with windows 2000 and vista, so i dont bother the OS itself, but why it's acting differently with a different OS?

  • Cause of laptop only booting once every 3-10 times

    - by user16441
    My 3-year old Asus EEE laptop has been working flawlessly in the past, but in the last week it has started behaving oddly. When I boot, one of the following happens: Screen remains totally black. Absolutely nothing comes up. I need to retry booting. (Happens 70% of the time). Laptop starts regular boot. However, somewhere during the boot process it goes black and I need to retry (20% of the time). Screen turning black is more likely when I move the laptop around during boot. Laptop boots properly. Once booted, all is fine. But I'm afraid to turn it off and have been keeping the laptop running till the night. Additional details: All normal lights light up when I boot; whichever of the scenarios goes down. There are no odd sounds or beeps, whichever of the scenarios goes down. I thought it might be the SSD drive that is dying, but it does not use SMART and it appears difficult to troubleshoot. I tried booting with and without the battery, but the scenarios are identical. Before completely investigating the hard drive, I'd like to hear opinions regarding the cause of this problem. Is this most likely the hard drive, or could there be another cause for these symptoms? Using Arch Linux.

  • Windows 8 doesn't start up after installation

    - by Raj BD
    I have a DELL INSPIRON n5110 machine running Windows 7 Home Premium 64-bit. It has 6GB of RAM and 500 GB hard disk capable to run any Windows and Linux system. And I recently attempted to install Windows 8 in the machine. Installation goes fine and smooth until the final stage when windows is done installing and GETS DEVICES READY. When GETTNG DEVICES READY reaches about 60%, the screen goes blank with the machine running. After a while it reboots. And after the new Windows Logo with dotted circles are done showing up, the screen goes blank again (when we'd expect login screen to show up). There is not even a cursor. I can see the HARD DISK ACTIVITY LED blinking but nothing shows up in the screen. I've tried CLEAN INSTALL several times. The DVD is fine, it installed and worked well in my friends' laptop PCs. I tried installing both PRO version and ENTERPRISE version and both 32-bit and 64-bit. But the problem was same everytime. Finally, I had to reinstall Windows 7 which installed and ran without any problem. The problem, we can guess, is GRAPHICS perhaps. I have Intel SandyBridge Graphics Mobile Chipset (Intel HD Graphics 3000). But if Windows 7 and Linux distrubutions like Mint and BackTrack can run on the machine, why on earth, would Windows 8 not run?

  • Windows 7 Upgrade Fail from Home Premium to Ultimate Professional

    - by Michael S-B
    I had a hard drive crash, which meant I had to install a new HDD in my Dell 64-Bit XPS 1350 (lovely computer). I had previously been running Windows 7 Ultimate Professional which I had upgraded from the OEM Win 7 Home Premium by means of a disk I purchased from my university. Using the Recovery disk from Dell I installed Windows 7 Home Premium successfully on the new hard drive, but when I have tried to upgrade via my disk to Ultimate it installs the whole thing, says its complete, but when I reboot, tells me: "This version of Windows could not be installed. Your previous version of Windows has been restored, and you can continue to use it." I've installed the drivers from Dell's driver disk, but still to no avail. I've also used Driver Robot to update all my drivers. I can't find a .dmp file anywhere under C:\$WINDOWS.~BT\Sources but I did find this file under C:\$WINDOWS.~BT\Sources\Panther. setupact.log https://www.dropbox.com/s/yzy7fhkxlzc235y/setupact.log If anyone could please advise me what I need to do to fix Windows so it will upgrade properly, I would greatly appreciate it.

  • What is the potential for a FUSE mount to destabilize a Linux server?

    - by 200_success
    I'm a sysadmin for a multi-user server, where students in our department have shell accounts. One of our users has requested that we install sshfs on it. I'm debating whether it would be wise to install sshfs as suggested. My main concern is whether a FUSE mount could make our server less reliable. In my experience, bad things can happen to servers when an NFS server suddenly becomes unavailable — the load average shoots up, and you might not be able to unmount it cleanly, to the point where a hard reboot might be necessary. If a FUSE-mounted server suddenly disappears, how hard might it be to clean up the mess? Are there any other likely catastrophes or gotchas I should consider? At least with NFS, only root can mount, and we can choose to mount NFS servers that we consider to be reasonably reliable. Let's assume that our users have no hostile intentions, but might do stupid things accidentally. Also, I'm not really worried about the contents of the filesystems they might mount, since our users already have shell access and can copy anything they want to their home directory.

  • Windows Azure: Announcing release of Windows Azure SDK 2.2 (with lots of goodies)

    - by ScottGu
    Earlier today I blogged about a big update we made today to Windows Azure, and some of the great new features it provides. Today I’m also excited to also announce the release of the Windows Azure SDK 2.2. Today’s SDK release adds even more great features including: Visual Studio 2013 Support Integrated Windows Azure Sign-In support within Visual Studio Remote Debugging Cloud Services with Visual Studio Firewall Management support within Visual Studio for SQL Databases Visual Studio 2013 RTM VM Images for MSDN Subscribers Windows Azure Management Libraries for .NET Updated Windows Azure PowerShell Cmdlets and ScriptCenter The below post has more details on what’s available in today’s Windows Azure SDK 2.2 release.  Also head over to Channel 9 to see the new episode of the Visual Studio Toolbox show that will be available shortly, and which highlights these features in a video demonstration. Visual Studio 2013 Support Version 2.2 of the Window Azure SDK is the first official version of the SDK to support the final RTM release of Visual Studio 2013. If you installed the 2.1 SDK with the Preview of Visual Studio 2013 we recommend that you upgrade your projects to SDK 2.2.  SDK 2.2 also works side by side with the SDK 2.0 and SDK 2.1 releases on Visual Studio 2012: Integrated Windows Azure Sign In within Visual Studio Integrated Windows Azure Sign-In support within Visual Studio is one of the big improvements added with this Windows Azure SDK release.  Integrated sign-in support enables developers to develop/test/manage Windows Azure resources within Visual Studio without having to download or use management certificates.  You can now just right-click on the “Windows Azure” icon within the Server Explorer inside Visual Studio and choose the “Connect to Windows Azure” context menu option to connect to Windows Azure: Doing this will prompt you to enter the email address of the account you wish to sign-in with: You can use either a Microsoft Account (e.g. Windows Live ID) or an Organizational account (e.g. Active Directory) as the email.  The dialog will update with an appropriate login prompt depending on which type of email address you enter: Once you sign-in you’ll see the Windows Azure resources that you have permissions to manage show up automatically within the Visual Studio Server Explorer (and you can start using them): With this new integrated sign in experience you are now able to publish web apps, deploy VMs and cloud services, use Windows Azure diagnostics, and fully interact with your Windows Azure services within Visual Studio without the need for a management certificate.  All of the authentication is handled using the Windows Azure Active Directory associated with your Windows Azure account (details on this can be found in my earlier blog post). Integrating authentication this way end-to-end across the Service Management APIs + Dev Tools + Management Portal + PowerShell automation scripts enables a much more secure and flexible security model within Windows Azure, and makes it much more convenient to securely manage multiple developers + administrators working on a project.  It also allows organizations and enterprises to use the same authentication model that they use for their developers on-premises in the cloud.  It also ensures that employees who leave an organization immediately lose access to their company’s cloud based resources once their Active Directory account is suspended. Filtering/Subscription Management Once you login within Visual Studio, you can filter which Windows Azure subscriptions/regions are visible within the Server Explorer by right-clicking the “Filter Services” context menu within the Server Explorer.  You can also use the “Manage Subscriptions” context menu to mange your Windows Azure Subscriptions: Bringing up the “Manage Subscriptions” dialog allows you to see which accounts you are currently using, as well as which subscriptions are within them: The “Certificates” tab allows you to continue to import and use management certificates to manage Windows Azure resources as well.  We have not removed any functionality with today’s update – all of the existing scenarios that previously supported management certificates within Visual Studio continue to work just fine.  The new integrated sign-in support provided with today’s release is purely additive. Note: the SQL Database node and the Mobile Service node in Server Explorer do not support integrated sign-in at this time. Therefore, you will only see databases and mobile services under those nodes if you have a management certificate to authorize access to them.  We will enable them with integrated sign-in in a future update. Remote Debugging Cloud Resources within Visual Studio Today’s Windows Azure SDK 2.2 release adds support for remote debugging many types of Windows Azure resources. With live, remote debugging support from within Visual Studio, you are now able to have more visibility than ever before into how your code is operating live in Windows Azure.  Let’s walkthrough how to enable remote debugging for a Cloud Service: Remote Debugging of Cloud Services To enable remote debugging for your cloud service, select Debug as the Build Configuration on the Common Settings tab of your Cloud Service’s publish dialog wizard: Then click the Advanced Settings tab and check the Enable Remote Debugging for all roles checkbox: Once your cloud service is published and running live in the cloud, simply set a breakpoint in your local source code: Then use Visual Studio’s Server Explorer to select the Cloud Service instance deployed in the cloud, and then use the Attach Debugger context menu on the role or to a specific VM instance of it: Once the debugger attaches to the Cloud Service, and a breakpoint is hit, you’ll be able to use the rich debugging capabilities of Visual Studio to debug the cloud instance remotely, in real-time, and see exactly how your app is running in the cloud. Today’s remote debugging support is super powerful, and makes it much easier to develop and test applications for the cloud.  Support for remote debugging Cloud Services is available as of today, and we’ll also enable support for remote debugging Web Sites shortly. Firewall Management Support with SQL Databases By default we enable a security firewall around SQL Databases hosted within Windows Azure.  This ensures that only your application (or IP addresses you approve) can connect to them and helps make your infrastructure secure by default.  This is great for protection at runtime, but can sometimes be a pain at development time (since by default you can’t connect/manage the database remotely within Visual Studio if the security firewall blocks your instance of VS from connecting to it). One of the cool features we’ve added with today’s release is support that makes it easy to enable and configure the security firewall directly within Visual Studio.  Now with the SDK 2.2 release, when you try and connect to a SQL Database using the Visual Studio Server Explorer, and a firewall rule prevents access to the database from your machine, you will be prompted to add a firewall rule to enable access from your local IP address: You can simply click Add Firewall Rule and a new rule will be automatically added for you. In some cases, the logic to detect your local IP may not be sufficient (for example: you are behind a corporate firewall that uses a range of IP addresses) and you may need to set up a firewall rule for a range of IP addresses in order to gain access. The new Add Firewall Rule dialog also makes this easy to do.  Once connected you’ll be able to manage your SQL Database directly within the Visual Studio Server Explorer: This makes it much easier to work with databases in the cloud. Visual Studio 2013 RTM Virtual Machine Images Available for MSDN Subscribers Last week we released the General Availability Release of Visual Studio 2013 to the web.  This is an awesome release with a ton of new features. With today’s Windows Azure update we now have a set of pre-configured VM images of VS 2013 available within the Windows Azure Management Portal for use by MSDN customers.  This enables you to create a VM in the cloud with VS 2013 pre-installed on it in with only a few clicks: Windows Azure now provides the fastest and easiest way to get started doing development with Visual Studio 2013. Windows Azure Management Libraries for .NET (Preview) Having the ability to automate the creation, deployment, and tear down of resources is a key requirement for applications running in the cloud.  It also helps immensely when running dev/test scenarios and coded UI tests against pre-production environments. Today we are releasing a preview of a new set of Windows Azure Management Libraries for .NET.  These new libraries make it easy to automate tasks using any .NET language (e.g. C#, VB, F#, etc).  Previously this automation capability was only available through the Windows Azure PowerShell Cmdlets or to developers who were willing to write their own wrappers for the Windows Azure Service Management REST API. Modern .NET Developer Experience We’ve worked to design easy-to-understand .NET APIs that still map well to the underlying REST endpoints, making sure to use and expose the modern .NET functionality that developers expect today: Portable Class Library (PCL) support targeting applications built for any .NET Platform (no platform restriction) Shipped as a set of focused NuGet packages with minimal dependencies to simplify versioning Support async/await task based asynchrony (with easy sync overloads) Shared infrastructure for common error handling, tracing, configuration, HTTP pipeline manipulation, etc. Factored for easy testability and mocking Built on top of popular libraries like HttpClient and Json.NET Below is a list of a few of the management client classes that are shipping with today’s initial preview release: .NET Class Name Supports Operations for these Assets (and potentially more) ManagementClient Locations Credentials Subscriptions Certificates ComputeManagementClient Hosted Services Deployments Virtual Machines Virtual Machine Images & Disks StorageManagementClient Storage Accounts WebSiteManagementClient Web Sites Web Site Publish Profiles Usage Metrics Repositories VirtualNetworkManagementClient Networks Gateways Automating Creating a Virtual Machine using .NET Let’s walkthrough an example of how we can use the new Windows Azure Management Libraries for .NET to fully automate creating a Virtual Machine. I’m deliberately showing a scenario with a lot of custom options configured – including VHD image gallery enumeration, attaching data drives, network endpoints + firewall rules setup - to show off the full power and richness of what the new library provides. We’ll begin with some code that demonstrates how to enumerate through the built-in Windows images within the standard Windows Azure VM Gallery.  We’ll search for the first VM image that has the word “Windows” in it and use that as our base image to build the VM from.  We’ll then create a cloud service container in the West US region to host it within: We can then customize some options on it such as setting up a computer name, admin username/password, and hostname.  We’ll also open up a remote desktop (RDP) endpoint through its security firewall: We’ll then specify the VHD host and data drives that we want to mount on the Virtual Machine, and specify the size of the VM we want to run it in: Once everything has been set up the call to create the virtual machine is executed asynchronously In a few minutes we’ll then have a completely deployed VM running on Windows Azure with all of the settings (hard drives, VM size, machine name, username/password, network endpoints + firewall settings) fully configured and ready for us to use: Preview Availability via NuGet The Windows Azure Management Libraries for .NET are now available via NuGet. Because they are still in preview form, you’ll need to add the –IncludePrerelease switch when you go to retrieve the packages. The Package Manager Console screen shot below demonstrates how to get the entire set of libraries to manage your Windows Azure assets: You can also install them within your .NET projects by right clicking on the VS Solution Explorer and using the Manage NuGet Packages context menu command.  Make sure to select the “Include Prerelease” drop-down for them to show up, and then you can install the specific management libraries you need for your particular scenarios: Open Source License The new Windows Azure Management Libraries for .NET make it super easy to automate management operations within Windows Azure – whether they are for Virtual Machines, Cloud Services, Storage Accounts, Web Sites, and more.  Like the rest of the Windows Azure SDK, we are releasing the source code under an open source (Apache 2) license and it is hosted at https://github.com/WindowsAzure/azure-sdk-for-net/tree/master/libraries if you wish to contribute. PowerShell Enhancements and our New Script Center Today, we are also shipping Windows Azure PowerShell 0.7.0 (which is a separate download). You can find the full change log here. Here are some of the improvements provided with it: Windows Azure Active Directory authentication support Script Center providing many sample scripts to automate common tasks on Windows Azure New cmdlets for Media Services and SQL Database Script Center Windows Azure enables you to script and automate a lot of tasks using PowerShell.  People often ask for more pre-built samples of common scenarios so that they can use them to learn and tweak/customize. With this in mind, we are excited to introduce a new Script Center that we are launching for Windows Azure. You can learn about how to scripting with Windows Azure with a get started article. You can then find many sample scripts across different solutions, including infrastructure, data management, web, and more: All of the sample scripts are hosted on TechNet with links from the Windows Azure Script Center. Each script is complete with good code comments, detailed descriptions, and examples of usage. Summary Visual Studio 2013 and the Windows Azure SDK 2.2 make it easier than ever to get started developing rich cloud applications. Along with the Windows Azure Developer Center’s growing set of .NET developer resources to guide your development efforts, today’s Windows Azure SDK 2.2 release should make your development experience more enjoyable and efficient. If you don’t already have a Windows Azure account, you can sign-up for a free trial and start using all of the above features today.  Then visit the Windows Azure Developer Center to learn more about how to build apps with it. Hope this helps, Scott P.S. In addition to blogging, I am also now using Twitter for quick updates and to share links. Follow me at: twitter.com/scottgu

  • Looking for definitive answer to accessing a network drive/NAS/SMB drive via Windows 7 HOME and Windows 7 Professional. Is it possible and how?

    - by Rob
    I want to be able to access my Lacie 2Big network drive in Windows 7 Explorer. I have a machine with Windows 7 Home and one with Windows 7 Professional. Neither Windows 7, home or pro, can access the drive. The Windows 7 Home machine displays the drive in its Explorer, with the capacity, but on clicking the icon, I get another window, blank with the busy pointer which does not eventually stop. The drive is working perfectly. How do I know this? Because I can access it with no problems on my Apple Mac, Windows XP home and Ubuntu machines on the same network as the Windows 7 machines. Except for the Windows XP home machine that required Lacie ethernet agent program, the Mac and the Ubuntu machines needed no setup, the drive appeared like any other drive. So my 2 questions: Is it possible to access a network share drive, e.g. a NAS like Lacie 2big in Windows 7 Home Premium and Windows 7 Professional. If so how? I read on Microsoft's own forums and elsewhere that network sharing drives, e.g. via SambaSMB is NOT possible on Windows 7 Home. Is this true? http://social.technet.microsoft.com/Forums/en-US/w7itprovirt/thread/e08c3500-a722-4b44-b644-64f94f63c8e5/ This question is a more comprehensive re-write of my earlier question: Windows 7 / TCP/IP network share guide - looking for to resolve failure to mount lacie network drive but works on XP,Linux,Mac. ...where I haven't received a solving answer, and I have tried to find a solution myself. Lacie themselves haven't offered a definitive solving answer either, but I suspect it's not just their drives but SMB/network share/NAS in general... This is utterly pathetic that Windows 7 home cannot access something as simple as a network drive, especially given that Windows XP home can. My research so far: Apparently it is possible on Windows 7 Professional, via the Local Security Policy, only on Windows 7 Professional, not Windows 7 Home: http://www.sevenforums.com/tutorials/7357-local-security-policy-editor-open.html http://answers.microsoft.com/en-us/windows/forum/windows_7-security/accessing-local-security-policy-in-windows-7-home/0c8300d0-1d23-4de0-9b37-935c01a7d17a http://social.technet.microsoft.com/Forums/en-US/w7itprosecurity/thread/14fc5037-3386-4973-b5d8-2167272ff5ad/ http://www.tomshardware.com/forum/75-63-windows-samba-issue Another solution offered is editing the registry, doesn't look promising to me, fiddly and not guaranteed, hard to produce a complete solution I think, given that everyone's registry can vary.

  • XenServer 6.0.2 path to installation media contains non-ascii characters

    - by cmaduro
    XenServer 6.0.2 install fails no matter what I do. I have confirmed that the md5 checksum on my ISO file is good. I tried installing from a mounted ISO file (remotely via iKVM). I tried installing from physical media. I tried installing from a bootable USB stick (using syslinux + contents of the ISO) All attempts have yielded the same result: When verifying the installation media, at 0% initializing, the following is reported: "Some packages appeared to be damaged." followed by a list of pretty much all the gz2 and rpm packages. If I skip the media verification the installer proceeds and then gives me an error when it reaches "Installing from base pack" at 0% which states "An unrecoverable error has occurred. The error was: 'ascii' codec can't decode byte 0xff in position 20710: ordinal not in range(128) Please refer to your user guide, or contact a Technical Support Representative, for further details" there is one option left which is to reboot. Apparently at some point during the processing of the repositories on the installation media non-ascii characters are found, which causes the installer to quit. How do I fix this? Here are my specs TYAN S8236 motherboard 2 AMD Opteron 6234 processors LSI2008 card connected to 2 1TB Seagate Constellation drives SATA, 1 500GB Corsair m4 SSD SATA and 1 Corsair Forse 3 - 64GB SSD SATA Onboard SATA connected to a slim DVD-+RW.

  • Debian (wheezy) force cache to RAM

    - by Marek Javurek
    I have Linux server running about 6 game servers. I have 3 GB total of RAM but I use only about 500 MB. Is there a way to cache one of my game servers (all the files - even not actually used maps etc. - about 1,5 GB) to RAM? The reason I want to do this is because my Linux server is virtual and the hard drives ar very slow, so there is really big IO wait time. IO: http://i.stack.imgur.com/7HLhB.png

  • Why is Excel 2010/2013 taking 10 seconds open any file?

    - by jbkly
    I have a fast Windows 7 PC with two SSDs and 16GB of RAM, so I'm used to programs loading very fast. But recently, for no reason I can figure out, Excel has started taking way too long to open Excel files (of any size--even blank files). This is occurring with Excel 2010 and with Excel 2013 after I upgraded, hoping to solve the problem. Here a couple scenarios: If I start Excel directly, it opens almost instantly. No problem there. If I start Excel directly, and then open any Excel file (.xls or .xlsx), it loads almost instantly. Still no problem BUT if I attempt to open any Excel file directly, with Excel not running, it consistently takes 10-11 seconds for Excel to start. I get no error messages, just a spinning cursor for 10-11 seconds, and then the file opens. During the delay while Excel is trying to start, I'm not really seeing any discernible spike in CPU or memory usage, other than explorer.exe. This problem is only occurring with Excel, not Word or any other program I'm aware of. I've searched around quite a bit on this question and found various others who have experienced it, but the solutions that worked for them are not working for me. For a few people it was a problem with scanning network drives, but my problem is purely with local files; I have no network drives, and the problem persists even with all network connections disabled. Some people suggested worksheets with corrupted formulas or links, but I'm experiencing this with ANY Excel file: even blank worksheets. Others thought it was a problem with add-ins, but I have all Excel add-ins disabled (as far as I can tell). One person solved it by disabling a "clipboard manager" process that was running in the background, but I don't have that. I've disabled as many startup and background processes as I can, but the problem persists. I've run malware scans, disk cleanup, CCleaner, and installed Excel 2013. I've deleted temporary files, enabled SuperFetch, and edited registry keys. Still can't get rid of the problem. Any ideas? My system details: Windows 7 Professional SP1 64-bit, Excel 2013 32-bit, 16GB RAM, all programs installed on SSD.

  • How to connect SAN from CentOS through two iSCSI Targets

    - by garconcn
    I had asked the similar question before. This time I want to use subnet for two iSCSI Targets, hence I start a new question. I have an old Promise VTrak M500i SAN Server. It comes with 2 iSCSI ports. I want to connect to two LUNs on the SAN server through two separate Targets from CentOS 5.7 64bits server. My network setup is as follows: CentOS server: Management network - 192.168.1.1 Storage network 1 - 192.168.5.2 Storage network 2 - 192.168.6.2 Promise SAN server: Management network - 192.168.1.2 iSCSI Port 1 - 192.168.5.1 iSCSI Port 2 - 192.168.6.1 I have two Logical Drives on this SAN and they are mapped as follows: Index Initiator Name LUN Mapping 0 iqn.2011-11:backup (LD0,0) 1 iqn.2011-11:template (LD1,1) Basically, I want the traffic to iqn.2011-11:backup LUN 0 through 192.168.5.1 network the traffic to iqn.2011-11:template LUN 1 through 192.168.6.1 network I don't use MPIO, just want to separate the traffic to avoid traffic jam. How do I achieve this? I am new to SAN stuff, please explain as much detail as you can. Thank you. The following are what I am doing now. After mapping the LUN to my pre-defined Initiators, the CentOS server can discover both Targets. [root@centos ~]# iscsiadm -m discovery -t sendtargets -p 192.168.5.1 192.168.5.1:3260,1 iscsi-1 192.168.6.1:3260,2 iscsi-1 [root@centos ~]# iscsiadm -m discovery -t sendtargets -p 192.168.6.1 192.168.6.1:3260,2 iscsi-1 192.168.5.1:3260,1 iscsi-1 [root@centos ~]# /etc/init.d/iscsi start iscsid is stopped Starting iSCSI daemon: [ OK ] [ OK ] Setting up iSCSI targets: Logging in to [iface: default, target: iscsi-1, portal: 192.168.6.1,3260] Logging in to [iface: default, target: iscsi-1, portal: 192.168.5.1,3260] Login to [iface: default, target: iscsi-1, portal: 192.168.6.1,3260] successful. Login to [iface: default, target: iscsi-1, portal: 192.168.5.1,3260] successful. [ OK ] [root@centos ~]# iscsiadm -m session tcp: [1] 192.168.6.1:3260,2 iscsi-1 tcp: [2] 192.168.5.1:3260,1 iscsi-1 When I check the LUN mapping on the SAN server for the two Logical Drives, both LUNs are connected through Port0-192.168.5.2 with the Initiator defined in CentOS. Assigned Initiator List: Initiator Name Alias IP Address LUN iqn.2011-11.centos centos.mydomain.com Port0-192.168.5.2 0 Initiator Name Alias IP Address LUN iqn.2011-11.centos centos.mydomain.com Port1-192.168.5.2 1 I assume the following is what I want: Initiator Name Alias IP Address LUN iqn.2011-11.backup centos.mydomain.com Port0-192.168.5.2 0 Initiator Name Alias IP Address LUN iqn.2011-11.template centos.mydomain.com Port0-192.168.6.2 1

  • Gnome-mount alternative in Ubuntu 10.04 or how to mount partition with normal user rights

    - by easyrider
    Hi, i was using gnome-mount to automount drives but in lucid it was removed. So is there any alternatives in lucid except editing fstab and programs that do so? Gnome-mount is a program which mounts disks using the same facilities as when mounting a disk as a normal user through Nautilus. There is no need to setup mountpoints or filesystems. This is particularly interesting if you want to use the automatically created mountpoints instead of manually specifying them for each disk.

  • VMWare Esxi Looking for Bottlenecks

    - by nextgenneo
    I have a VMWare ESxi box, 22GB ram, Dual Quad Core Xeon, 2 Sas drives + Write caching raid controller etc. Anyways, have about 30 small XP VM's running on it and starting to get some very slow boot times and other performance issues. I THINK its I/O but looking at the graphs not too sure what to look for. Any ideas on what to look for would be appreciated. Here is the data I've got so far: (I feel like my IO is high but not sure what to bench it against)

  • Mac OS X: Finder view options?

    - by trolle3000
    Hi there. In OS X 10.6, Finder usually looks something like this: The Finder window looks like that when you double-click on most folders or drives. However, whenever I mount a Truecrypt Volume and double-click that, it looks like this: Is there any way to default to the first view option for all types of folders? I tried view options in Finder, but it didn't seem to work.

  • How to correctly partition usb flash drive and which filesystem to choose considering wear leveling?

    - by random1
    Two problems. First one: how to partition the flash drive? I shouldn't need to do this, but I'm no longer sure if my partition is properly aligned since I was forced to delete and create a new partition table after gparted complained when I tried to format the drive from FAT to ext4. The naive answer would be to say "just use default and everything is going to be alright". However if you read the following links you'll know things are not that simple: https://lwn.net/Articles/428584/ and http://linux-howto-guide.blogspot.com/2009/10/increase-usb-flash-drive-write-speed.html Then there is also the issue of cylinders, heads and sectors. Currently I get this: $sfdisk -l -uM /dev/sdd Disk /dev/sdd: 30147 cylinders, 64 heads, 32 sectors/track Warning: The partition table looks like it was made for C/H/S=*/255/63 (instead of 30147/64/32). For this listing I'll assume that geometry. Units = mebibytes of 1048576 bytes, blocks of 1024 bytes, counting from 0 Device Boot Start End MiB #blocks Id System /dev/sdd1 1 30146 30146 30869504 83 Linux $fdisk -l /dev/sdd Disk /dev/sdd: 31.6 GB, 31611420672 bytes 255 heads, 63 sectors/track, 3843 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00010c28 So from my current understanding I should align partitions at 4 MiB (currently it's at 1 MiB). But I still don't know how to set the heads and sectors properly for my device. Second problem: file system. From the benchmarks I saw ext4 provides the best performance, however there is the issue of wear leveling. How can I know that my Transcend JetFlash 700's microcontroller provides for wear leveling? Or will I just be killing my drive faster? I've seen a lot of posts on the web saying don't worry the newer drives already take care of that. But I've never seen a single piece of backed evidence of that and at some point people start mixing SSD with USB flash drives technology. The safe option would be to go for ext2, however a serious of tests that I performed showed horrible performance!!! These values are from a real scenario and not some synthetic test: 42 files: 3,429,415,284 bytes copied to flash drive original fat32: 15.1 MiB/s ext4 after new partition table: 10.2 MiB/s ext2 after new partition table: 1.9 MiB/s Please read the links that I posted above before answering. I would also be interested in answers backed up with some references because a lot is said and re-said but then it lacks facts. Thank you for the help.

  • How to only allow particular programs to modify certain files?

    - by Mehrdad
    I want to make certain directories on my drives read-only except to particular programs who will have full permissions. For example, the Microsoft Word might be allowed to modify the files in my Documents folder, but other programs (such as the Command Prompt) would not be allowed to. I'm guessing this requires a file system filter driver of some sort, but I don't know which programs have this capability. Is there any (free) program that can do this for me?
