  • hdfs configuration

    - by Ananymous
    I am a newbie. Trying to setup a hdfs system to serve my data (I don't plan to use mapreduce) at my lab. So far I have read, cluster setup in but I am still confused. Several questions: Do I need to have a secondary namenode? There are 2 files, masters and slaves. Do I really need these 2 files eventhough I just want hdfs? If I need them, what should go in there? I assume my namenode in masters and datanodes as slaves? Do I need slaves nodes What configuration files are needed for namenode, secondary namenode, datanode and client? (I assume core-site.xml is needed for all 4)? In addition, can someone suggest a good configuration model? sample configuration for namenode, secondary namenode, datanode, and the client would be very helpful. I am getting confused because it seems most of the documentation assumes I want to use map-reduce which isn't the case.

  • WSS Search fills 10 GB limit on SBS server 2011

    - by Kactus
    I've got a SBS Server 2011 Standard SP1 that isn't very busy. 2 Users local and 2 remote. We have sharepoint that has maybe a dozen small documents at most. I've just started getting the following two error occur Could not allocate space for object 'dbo.MSSBatchHistory'.'IX_MSSBatchHistory' in database 'WSS_Search_SERVER' because the 'PRIMARY' filegroup is full. Create disk space by deleting unneeded files, dropping objects in the filegroup, adding additional files to the filegroup, or setting autogrowth on for existing files in the filegroup. And CREATE DATABASE or ALTER DATABASE failed because the resulting cumulative database size would exceed your licensed limit of 10240 MB per database. Digging around in SQL manager I see that WSS Search DB file size is 10241MB, the log file is only 147 MB Firstly, why is WSS Search taking up so much space? How can I stop it from doing so, and what can I do now to get things running ok. I know about log file truncating and this isn't the case here since the log is tiny. Any help is appreciated. There is plenty of free space on the disk (791GB free) Thanks Kactus

  • Some guest networking and VMware Tools functionality broken with Sprint SmartView on the host

    - by Mads
    Using VMware Workstation 6.5.3 on Vista 64-bit. I started having problems with VMware networking about 6 months ago after upgrades to Sprint SmartView. I did not have problems previously, but I don't know if that is because I was lucky. The main symptoms of the problem when SmartView is installed are: I can no longer drag files from the host to copy them to the guest. When they are dragged, the disallowed cursor (the circle with a slash) shows in the guest. If I try to enable shared folders in the guest while it is running, I will not be able to see the shared files and will be informed that networking is not working. I can still ping guests from the host and I can still access network services via NAT most of the time when connected via my USB broadband adapter. When I configure shared folders so they are "always enabled" (with a mapped drive), I can access files on the via the mapped folders. I can also copy the file on the host and then paste it in the guest, as was suggested in some other threads concerning drag-and-drop problems that I found. The VMware Tools icon is showing in all cases and I don't see any obvious errors in the host's event viewer. If I uninstall SmartView, the problems disappear. If SmartView (current version is 2.28.0082) is reinstalled I will experience the same problems. I have tried uninstalling/reinstalling VMware and SmartView in various ways but it appears tha these problems are consistent when SmartView is installed (not just when it is running or connected, but when it is present on the system). I'm wondering if this is a combination of software (WS 6.5.3, Vista64, and SmartView) that works for other people, which would indicate a problem that is peculiar to my configuration.

  • Debian, How to convert filesystem from ISO-8859-1 into UTF-8?

    - by Johan
    I have a old pc that is running Debian stable, that is in need of a upgrade. The problem is that it is using latin1 (ISO-8859-1) for everything, and since the rest of the world has moved to UTF-8 I plan to convert this computer as well. And for this question I will focus in on the files that are served with Samba, and some has some latin1 characters in the filenames (like åäö). Now my plan is to move all data of this old computer onto and a brand new one that is running Debian stable (but with UTF-8). Does anybody have a good idea? Thanks Johan Note: later I plan to use iconv to convert the content of some files with something like this: iconv --from-code=ISO-8859-1 --to-code=UTF-8 iso.txt > utf.txt However I don't know of a good way to convert the filesystem it self. Note: Normally I usaly just scp from one computer to the next, but then I end up with latin1 characters in the utf-8 filesystem... Update: Did a small test round with a hand full of files (with funny chars) in the filenames, and that seemed like it could work. convmv -r -f ISO-8859-1 -t UTF-8 * So it was only to execute with the --notest convmv -r -f ISO-8859-1 -t UTF-8 --notest * Nothing more to it.

  • Openldap startup problems after upgrade

    I am trying to syncrhonize a ldap slave and master server. The master server is using openldap 2.3.43-12 and the slave server is using openldap 2.4.23.

  • Ubuntu: Tar doesn't work correctly

    - by Phuong Nguyen
    It looks like tar is having some problems. I installed Ubuntu 10.04 alpha a few of weeks ago. After that, this alpha version is so terrible that I must switched back to 9.10. So, I backed up all of my profiles data (/home/my_user_name) to my_user_name.tar.gz Here what I did: (in U10.04) Open Nautilus and goto /home/my_user_name Press Ctrl+H to view all hidden files. Press Ctrl+A to select all files Right click and choose [Compress...] Now, when I have set up Ubuntu 9.10 again, I extract the tar using Extract Here command from Nautilus. Funny things happened: Instead of extracting to current folder, the archive manager create a folder named my_user_name and put the extracted content into it. All of the files that I placed directly under /home/my_user_name doesn't get extracted All of the directories that started with . (dot) is not extracted. I wonder if there is any incompatibility between tar in U10.04alpha and U9.10 that cause the problem? Now every of my email, basket data is long gone. I'm freaking right now. Is there anything I can do to get the tar return back my data?

  • ASP.NET Session State SQL Server 2008 R2 Freezes with High CPU Usage

    - by jtseng
    Our ASP.Net website uses SQL Server as the session state provider. We currently host the database on SQL Server 2005 since it does not play well on 2008 R2. We would like to know why, and how to fix it. hardware setup Our current session state server has SQL Server 2005 with the files hosted on a single local disk. It is one of our oldest servers since it has served us well, and we never felt the need to upgrade it. The database is about 2 GB holding 6000 sessions. (The sessions are a little big, but we need it.) We have another server with SQL Server 2008 R2 with a much faster CPU, much more RAM, and a much faster hard disk. situation One day, we have a huge surge in traffic. The transaction log growth on SQL Server freezes the server for 10's of seconds, allowing only a few requests through in minutes. So we load up the new server with ASPState with very large data and log files and point all of our applications to the new server. It chugs along fine for about 5 minutes, and then the CPU usage jumps up to 50% of the 16 cores that Standard Edition can use and freezes for 10's of seconds at a time. The files do not record any autogrowth events. The disk queue is nice and low. RAM usage is low. CPU usage on our old server has never been higher than 5%. What happened on the new server? Alternatively, I would like to hear success stories with ASP.NET session state server running on SQL Server 2008 R2 with an average write load of 30MB/sec with bursts up to 200MB/sec.

  • VirtualHost on WAMPSERVER not working

    - by Martin C
    I currently have WAMPSERVER 2.2 set up on my PC. I'm trying to set up a new host called pplocal.local I made the changes in httpd.conf to uncomment this: Include conf/extra/httpd-vhosts.conf Then, I edited httpd-vhosts.cong and I added the following: NameVirtualHost 127.0.0.1 <VirtualHost 127.0.0.1> DocumentRoot "E:/wamp2/www/" ServerName localhost </VirtualHost> <VirtualHost 127.0.0.1> DocumentRoot "E:/wamp2/www/pp/" ServerName pplocal.local <Directory "E:/wamp2/www/pp/"> Options Indexes FollowSymLinks MultiViews AllowOverride all Order Deny,Allow Deny from all Allow from 127.0.0.1 </Directory> CustomLog "E:\wamp2\logs\pplocal-access.log" common ErrorLog "E:\wamp2\logs\pplocal-error.log" Im my windows 'hosts' file I added: 127.0.0.1 localhost 127.0.0.1 pplocal.local Then, I restarted apache. If I type localhost in my browser I get the files at E:/wamp2/www/ If I type pplocal.local in my browser I get the files at E:/wam2/www/ instead of those at E:/wamp2/www/pp/ I have followed several tutorials and can't see what I'm doing wrong. I'm new to editing the files associated with apache so any advice is appreciated. Thanks

  • how to back up data from a machine that keeps hanging

    - by Amit Phatarphekar
    Hello - I have a storage server running opensolaris. But lately its been acting up - it hangs at random times due to some SCSI/ATA related error messages. I've tried to fix it without any progress, so I'm giving up now. The machine keeps hanging every 30 minutes or 1 hr ...sometimes after 4 hrs. Its very unpredictable. So I've decided to just reformat the storage server and start from scratch...maybe I'll just not use solaris and install something else, since the errors are related to solaris running on ATA HDD or something. Question - Before I reformat it, I want to back up some of the important data on it. Like it has a VM with 200 GB disk files, it has a whole bunch of ISOs stored on it etc etc. I'm using a simple scp to copy the files over to a different machine. My issue is that, because the machine hangs....sometimes my file copy is incomplete and I have to start all over again. Lets say I'm trying to copy a 200GB file which takes like 4 hrs....IF the machine hangs before the whole file i copied over...I have to recopy the file from scratch. Is there a solution to copy the files over such that if the machine hangs or network goes down..the copying can resume from where it left off? - like if 50 GB of a 200GB file was copied and machine hung....next time, it'll just continue to copy rest of the amount, instead of starting all over again. Thanks Amit

  • How can I copy a VMware Fusion virtual machine to a FAT32 partition?

    - by Michael Prescott
    I created the virtual machine on a host running OS X. I then moved the machine to a FAT32 partition on an external drive. It moved the first time without error. Then I moved it from the external drive to a host running Ubuntu 9.10. I had to move to a FAT32 partition first because Ubuntu doesn't recognize Mac OS Extended partitions on the drive. So, the virtual machine (vm) ran on the ubuntu host for a while and then I moved it back to the FAT32 partition and from there back to the OS X host. I worked on the vm for a while on the OS X host and then attempted to move it back to the FAT32 partition. I get the following system error: The Finder can’t complete the operation because some data in “my-virtual-machine” can’t be read or written. (Error code -36) Interestingly, I can move the file to another OS X partition, just not FAT32. I also perused VMware's forums and found advice to set permissions on all files and folders to 777. I did this, but have had no success. I notice the the files within the vm package are 777 now, but there is an extended attributes symbol on their permission details "rwxrwxrwx@" Since I can copy the vm between OS X partitions, but not to non OS X partitions, and all files and folders withing the vm package and the package itself have permissions of 777, I speculate that the "@" is the problem. How can I remove the "@" or is there something else I need to modify to allow me to copy/move the vm to other hosts?

  • Drobo-like linux file server - how do I do it?

    - by John Hunt
    I've been pondering for a long time about how I can set up a server which operates much like the Drobo storage thing. The reasons I don't actually want a drobo is because I've heard scare stories, plus I'd like to do this on the cheap. So ideally I'm looking for something like lvm so I can create a logical volume that spans many hard disks of varying sizes... obviously that only offers redundancy if I put the LV on a raid array (as far as I know..) I have however been reading about technologies such as Microsoft's drive extender which duplicates files at the filesystem level and makes sure that the mirrored files are on a different phyiscal disk.. does anyone know or recommend a filesystem or method like this as it'll hopefully make much better use of the space available than raid ever could. Performance isn't an issue, I'd just really like to make the most of the hard disks I have lying around whilst having a bit of redundancy incase a disk dies. I understand full well that this is no replacement for a backup, but I'll only be storing files of medium importance and using the nas itself as a backup of my main pc and other systems. Thanks in advance! I'm hoping zfs or btrfs or something can do something clever for me :)

  • APC fragmentation on EC2 Micro for Wordpress + W3TC

  • Blink build with Xcode failed

    I found a GPL-ed SIP client for Mac, Blink. I'd like to build it from source since the binaries are only available as paid download. Just FYI i'm studying programming at university but have no experience in building complex application from source. After downloading the content of the repository i opened the Xcode project and tried to build on OS X 10.7, Xcode 4.2.1.

  • Non-alphanumeric character folder name auto-completion problems

    - by viking
    I have been working with Windows 7's command line and have some folders that begin with non-alphanumeric characters. When I try to use tab completion to complete the folder name, the initial character is not included inside of the quotation marks. Example: C:\Users\username\!example is the folder I want to get into, but when I type: cd ! and press <Tab> to autocomplete, it will complete to cd !"!example" instead of the expected cd "!example" Any ideas on how to fix this besides changing the folder names? EDIT: I realize I could just tab through the entire list after entering cd, but I'm looking for a way to speed up the process. I have been spending a significant amount of time navigating these folders. UPDATE: This also happens if there is a space in the directory. For example: "c:\Program Files". In order to continue using tab to complete, first the second quote has to be deleted. C:\Program press Tab "C:\Program Files" is what appears. To navigate to a subdirectory, first the quote after Program Files has to be deleted before the next directory can be spelled out.

  • Using WebDAV for automated downloads

    - by Geo Ego
    I currently manage a number of sites (at one point about a dozen, currently four, but soon growing into the dozens or hundreds) that serve a piece of software to clients at their remote locations. Our web server is Windows SBS Server 2k3, and the remote servers are Windows Server 2k3.When we have new versions of the software, I upload this new software to a specific directory and rename it; each time the clients boot, they pull their software from that specific directory. With just a few sites, it's no problem for me to RDP in and copy the files over. As the number grows, this will quickly become quite unwieldy. So I'm thinking that WebDAV would be part of a solution, so that I could simply push the newest version to our server (Windows SBS Server 2003) and make it available to the sites to grab. However, on the remote server side, what are some suggestions for automating the download? I only want the servers to download the files during downtime (between 3 AM and 9 AM), and I only want them to download if there is a new version available. I had thought of writing a program that checked the files on the WebDAV server at a regular interval, compared a hash of the current software to a hash of the software on the server, and only downloaded if they were different, but I'm wondering if there is something I am unaware of that can automate the process.

  • SVN hangs on commit - any suggestions for troubleshooting?

    - by Richard Beier
    We're having a problem with SVN... Subversion clients such as TortoiseSVN hang when we commit any more than a few files at a time to our server. Everything appears to actually be committed successfully to the repository; but the client hangs after all the data has been transmitted. We're using version 1.4.4 of the SVN server. We use the svn:// protocol rather than http to connect. We've reproduced this problem with several clients: TortoiseSVN (1.6.10), AnkhSVN (2.1), and the Silk command-line client (1.6.12). This is happening for everyone on the team, though some people seem to be more affected than others. If someone commits only a few files, it often works; but with more than half a dozen files, it usually hangs. Does anyone have troubleshooting suggestions? This has been happening sporadically for a while, but it's become pretty consistent lately. We've been working around the issue by killing the hung SVN client, doing "svn cleanup", and then doing "svn up"; but sometimes that causes tree conflicts. Another workaround is to blow away the workspace and check it out again after every commit; but of course that's pretty annoying. Are there any diagnostics that could help us troubleshoot this? We're considering upgrading to SVN 1.6 server, and installing the server on a new machine; but we're wondering if there's an easier solution. Thanks for your help, Richard

  • Replacing quotes in a file

    - by Matthijs
    I have a large number of large semicolon-separated data files. All string fields are surrounded by double quotes. In some of the files, there are extra quotes in the string fields, which messes up the subsequent importing of the data for analysis (I'm importing to Stata). This code allows me to see the problematic quotes using gnu-awk: echo '"This";"is";1;"line" of" data";""with";"extra quotes""' | awk 'BEGIN { FPAT = "([^;]+)|(\"[^\"]+\")"}; {for ( i=1 ; i<=NF ; i++ ) if ($i ~ /^"(.*".*)+"$/) {print NR, $i}}' 1 "line" of" data" 1 ""with" 1 "extra quotes"" but I do not know how to replace them. I was thinking of doing the replace manually, but it turns out that there are several hundred matches in some of the files. I know about awk's -sub-, -gsub-, and -match- functions, but I am not sure how to design a search and replace for this specific problem. In the example above, the respective fields should be "This", "is", 1, "line of data", "with", "extra quotes", that is: all semicolons are separators, and all quotes except for the outermost quotes should be removed. Should I may be use -sed-, or is -awk- the right tool? Hope you can help me out! Thanks, Matthijs

  • DVD drive won't work after installing software

    - by Dan
    DVD drive was already region-free but for some reason would not play a certain DVD as it was the "wrong region". This is the first time I've played a DVD on the drive, but I've imported a lot of CDs before and they always worked fine, even CDs bought from the USA (I live in the UK). To get around this, I downloaded a piece of software called "DVD Region Killer". (Clicking the link won't start the download, so go ahead and check it.) After this, the drive isn't recognised. It won't show up in "My Computer", and when I insert a disc it will start to whir but not take action, i.e. iTunes won't recognise that I have put a CD in. In the Device Manager, the drive shows up with a caution-sign. The device status reads: Windows cannot start this hardware device because its configuration information (in the registry) is incomplete or damaged. (Code 19) Disabling, uninstalling and reinstalling does not help. Clearly the software download is the issue, but it is difficult to remove. The only files I can find in Program Files are: C:\Program Files (x86)\Elaborate Bytes\DVD Region Killer which contains a changelog and a HTML document which has no info on uninstalling. It doesn't show up on "Add or Remove Programs", or even as a background process when I press ctrl-alt-del. Apparently it has no interface as such, and can be accessed by an icon in the system tray, (see review in link) but I don't see the icon. If it helps to know, I have a Dell Inspiron running Windows 8 64-bit, and the model of the DVD drive is: MATSHITA DVD+-RW UJ8C2 Thanks in advance.

  • Using NFS for scalable PHP/MySQL web application

    - by Jeroen Moons
    Here's the situation: I have a PHP/MySQL web application that accepts user uploads (pdf files). From these pdf files' pages a preview image is made on the fly and presented to the web app's users. Some pdfs might be on the large side, most will be under 50 MB but some extreme cases could be as large as a few hundred MB. A little waiting for the preview image for large pdf files is acceptable but no more than a minute let's say. Everything is running on one server for now, but soon the app will hit the server's limit on both storage and processing power. My idea to solve the problem: To deal with this situation I had the idea of having one or more pdf processing servers as needed, and one or more file storage servers. These two types of servers are mounted to the server on which the actual app runs using NFS. The app could then use GearMan to delegate pdf processing tasks to these processing servers. The processing server can mount the storage server and read the file stored there, process it and write its output to that server. The servers I'm talking about will be amazon ec2 instances. The web app returns a link to the resulting pdf preview image on the storage server that was used which can then be used on the front end to show the image to the user. My question: I have zero experience with apps that use multiple servers, is this idea viable or is there a better way to do it? Is an NFS setup fast and reliable enough for this situation?

  • What is the ideal way to set up multiple FTP enabled web accounts on Fedora?

    - by Nicholas Flynt
    I'm setting up a test server for use as a web development platform, and I'd like to mimic as closely as I can a typical shared hosting setup. That is, I'd like my server to have multple user FTP accounts, each of which links to a directory containing the webroot of the site, and I'd like apache to be able to easily see and manupulate these files. I'll admit: I'm not as familiar with Fedora as I'd like, I run Ubuntu on my home box and SElinux is giving me some grief. My initial plan was to have each user FTP into their home directory, and put the web directory there as well, but SElinux throws a hissy fit when apache tries to access anything outside of its web directory, so that plan was a no go. Would it be wise to continue this route, and perhaps mount web directories in user home folders so that FTP could still be used to access them, even though apache saw them in var/www like it expects? Would it make more sense to set up custom FTP accounts and use a single FTP user on the server box? What's the general course of action on something like this? I'm using vsftpd right now to host web directories, which is why I'm liking the home directory approach (it's simple and secure) but of course there's bound to be a better way to go about it. Thanks. (I'll leave other things, like restricted DB access and such, to another post. I'm interested right now with just getting FTP and apache to play nice in a multi-user environment.) PS: For the record, an issue I ran into when doing all of this was that if apache isn't running as the same user as the FTP account is saving as, there are permissions errors when FTP creates files, requiring the remote user to chmod the files to fix it. A logical fix would be to run apache in a special group, put all web users in this group, and have FTP access default to giving this group read/write access to everything like apache would expect, but I never could figure out how to accomplish this. Bonus points and cake if you know a solution.

  • chrooted sftp user with write permissions to /var/www

    - by matthew
    I am getting confused about this setup that I am trying to deploy. I hope someone of you folks can lend me a hand: much much appreciated. Background info Server is Debian 6.0, ext3, with Apache2/SSL and Nginx at the front as reverse proxy. I need to provide sftp access to the Apache root directory (/var/www), making sure that the sftp user is chrooted to that path with RWX permissions. All this without modifying any default permission in /var/www. drwxr-xr-x 9 root root 4096 Nov 4 22:46 www Inside /var/www -rw-r----- 1 www-data www-data 177 Mar 11 2012 file1 drwxr-x--- 6 www-data www-data 4096 Sep 10 2012 dir1 drwxr-xr-x 7 www-data www-data 4096 Sep 28 2012 dir2 -rw------- 1 root root 19 Apr 6 2012 file2 -rw------- 1 root root 3548528 Sep 28 2012 file3 drwxr-x--- 6 www-data www-data 4096 Aug 22 00:11 dir3 drwxr-x--- 5 www-data www-data 4096 Jul 15 2012 dir4 drwxr-x--- 2 www-data www-data 536576 Nov 24 2012 dir5 drwxr-x--- 2 www-data www-data 4096 Nov 5 00:00 dir6 drwxr-x--- 2 www-data www-data 4096 Nov 4 13:24 dir7 What I have tried created a new group secureftp created a new sftp user, joined to secureftp and www-data groups also with nologin shell. Homedir is / edited sshd_config with Subsystem sftp internal-sftp AllowTcpForwarding no Match Group <secureftp> ChrootDirectory /var/www ForceCommand internal-sftp I can login with the sftp user, list files but no write action is allowed. Sftp user is in the www-data group but permissions in /var/www are read/read+x for the group bit so... It doesn't work. I've also tried with ACL, but as I apply ACL RWX permissions for the sftp user to /var/www (dirs and files recursively), it will change the unix permissions as well which is what I don't want. What can I do here? I was thinking I could enable the user www-data to login as sftp, so that it'll be able to modify files/dirs that www-data owns in /var/www. But for some reason I think this would be a stupid move securitywise.

  • Installed Paragon HFS+ for Windows 8, now my pc won't recognize the external firewire drive

    - by Steve
    I'm not incredibly knowledgeable about computers and I really need some help. Just got a Seagate external firewire drive this morning. I downloaded the necessary pc driver (Paragon HFS+ for Windows 8) through their website per the instructions that came with the drive. After installation, I restarted and the pc recognized the firewire drive just fine. About three hours into copying files from my pc to the firewire drive, it gave me an error and told me the files couldn't be copied. When I clicked to get out of the message, the computer crashed. After an hour of it trying to repair itself in safe mode, it restored me to an earlier version before the system crashed. Here's my current dilemma: The Paragon HFS+ is still showing up in my programs as installed, but the Device Manager is not recognizing the drive. When I try to uninstall and reinstall Paragon, it interrupts me with a message saying "The setup must update files or services that cannot be updated while the system is running" and basically gives me the finger. I have no idea what to do now, as it won't let me uninstall and reinstall Paragon, and I have no idea why it crashed my computer in the first place. Is there possibly another Mac - PC firewire driver I can try downloading instead? I really don't know what I'm doing and any help would be greatly appreciated.
