  • RAID 50 24Port Fast Writes Slow Reads - Ubuntu

    - by James
    What is going on here?! I am baffled. serveradmin@FILESERVER:/Volumes/MercuryInternal/test$ sudo dd if=/dev/zero of=/Volumes/MercuryInternal/test/test.fs bs=4096k count=10000 10000+0 records in 10000+0 records out 41943040000 bytes (42 GB) copied, 57.0948 s, 735 MB/s serveradmin@FILESERVER:/Volumes/MercuryInternal/test$ sudo dd if=/Volumes/MercuryInternal/test/test.fs of=/dev/null bs=4096k count=10000 10000+0 records in 10000+0 records out 41943040000 bytes (42 GB) copied, 116.189 s, 361 MB/s OF NOTE: My RAID50 is 3 sets of 8 disks. - This might not be the best config for SPEED. OS: Ubuntu 12.04.1 x64 Hardware Raid: RocketRaid 2782 - 24 Port Controller HardDriveType: Seagate Barracuda ES.2 1TB Drivers: v1.1 Open Source Linux Drivers. So 24 x 1TB drives, partitioned using parted. Filesystem is ext4. I/O scheduler WAS noop but have changed it to deadline with no seemingly performance benefit/cost. serveradmin@FILESERVER:/Volumes/MercuryInternal/test$ sudo gdisk -l /dev/sdb GPT fdisk (gdisk) version 0.8.1 Partition table scan: MBR: protective BSD: not present APM: not present GPT: present Found valid GPT with protective MBR; using GPT.

I can't think of anything that would be causing this other then fundamental driver errors? I can't seem to get much/if any higher then the 361MB a second, is this hitting the "SATA2" link speed, which it shouldn't given it is a PCIe2.0 card. Or maybe some cacheing quirk - I do have Write Back enabled. Does anyone have any suggestions? Tests for me to perform? Or if you require more information, I am happy to provide it! This is a video fileserver for editing machines, so we have a preference for FAST reads over writes. I was just expected more from RAID 50 and 24 drives together... EDIT: (hdparm results) serveradmin@FILESERVER:/Volumes/MercuryInternal$ sudo hdparm -Tt /dev/sdb /dev/sdb: Timing cached reads: 17458 MB in 2.00 seconds = 8735.50 MB/sec Timing buffered disk reads: 884 MB in 3.00 seconds = 294.32 MB/sec EDIT2: (config details) Also, I am using a RAID block size of 256K. I was told a larger block size is better for larger (in my case large video) files. EDIT3: (Bonnie++ Results. Would love some guidance with this!)

  • Can I upgrade the processor in my laptop (Satellite L455)?

    - by Alan Robinski
    I have a Toshiba Satellite L455-S5975 which is about three years old. The processor is currently an Intel Celeron 900. Does anyone know if it is possible to upgrade this to a newer one? I have heard the Core 2 Duo T6600 is a compatible replacement for my processor on other brands of computers, and I know the two have the same socket type (PGA478). I mostly need to know if this or any other newer processors are compatible with the Satellite's motherboard.

  • How to fix the boot loader with an installation disk at hand

    - by Bragboy
    Hi, I recently messed up my Master Boot Record and my system is not booting. I was dual booting Windows and Ubuntu. Both of them are not loading now. I don't care if I lose my windows, but I want my Ubuntu back!! How to get it (I have a fresh Ubuntu 10.10 LTS disk with me). I went through the install wizard but feared that I may loose my existing installation/setup. Thats why I came here to check what is the ideal procedure to only update the Boot record instead of a full installation.

  • sudo credential caching on by default

    - by Dan Dman
    Just installed a minimal ubuntu 12.04, then installed xfce4 and xinit from the command line after first boot. Totally vanilla installation afaik. I'm noticing that sudo caches the password until I issue sudo -k to clear it. This is unexpected behavior in my mind. I've run xfce4 before and don't recall credential caching being on, nor have I experienced it in the many previous ubuntu installs I've had over the years. Is this a new feature of Ubuntu? Is this something that's the result of the minimal install? Is this an xfce default that's been added recently?

  • How can I fix 'no wubildr' error in WUBI on Windows 7?

    - by Austin
    Good Evening All, I just got my HP Laptop Back from the factory and then I tried to install Ubuntu. It got through the whole installation, however, when I restarted and chose Ubuntu a quick screen flashes that says: Try (hd0,0) NTFS5: no wubildr Try (hd0,1) NTFS5: Then it quickly goes to the Boot Loader which I am presented with: Windows 7 (loader) (on /dev/sda1) Windows Vista (loader) (on /dev/sda2) Windows Vista (loader) (on /dev/sda3) Of course if I click Win 7 it'll go to the main screen to choose between Win 7 or Ubuntu, if I choose Vista, it'll come with an error of sorts. The strange thing is, I looked in my C:/ Drive and I see wubildr and wubilder.mbr Idk if it makes a difference but I am running a 64-bit processor. Installed the 64-bit desktop version and am presented with ultra-fail. I've gone to: http://ubuntuforums.org/showthread.php?s=4d54a8d3760f6fe805156524b7ab9acf&t=798283&page=1 But have had no luck.

  • How to add menu items in System menu

    - by Leonardo Montenegro
    I want to insert an item to System menu: Help and Support About Gnome About Ubuntu More specifically, I want to insert a new item under "About Ubuntu". Trying with alacarte doesn't work. Cloning "ubuntu-about.desktop" file and changing his attributes doesn't work too (I even rebooted the computer after that). Searching for categories in "/usr/share/desktop-directories" haven't worked too, and searching for "core" and "about" entries in /etc/xdc/menus neither. It isn't as easy as I thought it would be. Anyone have any suggestions?

  • OpenVPN bridged not pinging beyond openvpn server on Ubuntu/Windows 2003

    - by ani
    I set up an OpenVPN server using Ubuntu and a windows server 2003 client to interconnect two networks between two different offices. They can now ping each other, but the rest of the network cannot be contacted by the windows client.

  • Ubuntu 12.04 crash analysis - strange binary data on all open files at the moment of crash

    - by lanbo
    A couple of hours ago we got a system crash on Ubuntu 12.04. We checked all the log files and there is nothing suspicious to blame to. Last stuff that was logged was some dovecot activity. There are no kernel panic messages. Nothing. It is a new server (new hardware) we are testing before production. And because it is new hard, I'm suspicious the problem may be due to some faulty hardware. We already run memtester with no problem detected. I'll be happy to hear from other hardware testing tools (the machine has SSD). Anyway, the thing I wanted to ask you is a different one. The strange thing is on every open file at the moment of the crash we found the next sequence of symbols was written into them: "@^@^@^@^@^@^@...". For example, on the syslog log file we got: Apr 16 15:53:56 odyssey dovecot: pop3-login: Aborted login (auth failed, 1 attempts): user=<info>, method=PLAIN, rip=46.29.255.73, lip=5.9.58.177 ^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^@^ [these continues for about 1000 chars...] ^@^@^@^@Apr 16 15:55:12 odyssey kernel: imklog 5.8.6, log source = /proc/kmsg started. We got all these symbols in all open files. These include: syslog, mail.log, kern.log, ... But also on some logs that are output by php scripts run in CRONs from user accounts (not root). So, any idea why all open files got these characters written during the crash? This is pretty bad since the crash corrupted many files (we don't even know which other ones may be affected). We are suspicious that all open files (in write mode maybe) at the moment of the crash got all these symbols inserted. Why is that? BTW [in case it helps], the system automatically rebooted after the crash but Apache did not start. There were not traces in /var/apache2/*log why apache did not start. After running a "service apache2 start" it started with no problems. Also, we rebooted the machine manually and Apache also started on reboot. But it did not start after the crash and no errors were reported. Thanks guys!

  • U1 music shows unknown artist, how can I make it recognize m4a files?

    - by bisi
    Hello all, I am in the process of uploading my music library as a backup to U1, but I figured, why not also enjoy Ubuntu 1 music on my iPhone? With a few difficulties to start, the upload is now in progress, but I've noticed that there is a huge percentage of files in the unknown artist folder, and I believe it is all of my m4a files. They play fine, but without any information. Coming from an iTunes background, and having bought the majority of my music on the iTunes store, I wonder how I could make this work, easily? I am on Maverick (afaik), but About Ubuntu shows 11.04. I use Banshee as my music manager, and I monitor my sync using Ubuntu one preferences, ubuntuone-indicator and magicicada. The total file size of my music folder is 38.9GB. Thank you for your help!! And apologies if I couldn't find a thread where this was already covered...

  • Installing and configuring Zend Framework 2 server-wide [Ubuntu] and test driving ZendSkeletonApplication

    - by kinologik
    I'm trying to have ZF2 installed for all my subdomains at once (Ubuntu 12.04). ZF2 just launched its first stable version, so I wanted to install it on my development server and finally get my hands dirty with it. I downloaded ZF2 and unzipped the files in /var/ZF2/ (which now contains Zend/[all components]). I then edited /etc/php5/apache2/php.ini and added the path to the ZF2 files: include_path = ".:/var/ZF2" I then downloaded the ZendSkeletonApplication and unzipped it in /var/www/skeleton. I know it is suggested to composer.phar to install ZF2 application, but: I don't want to make a local installation of ZF2... I want to make a server-wide installation be able to use my Zend components on all my domains/subdomains on my development server. Before using any automatic installation process, I'd really like to understand that process by doing it manually at first. Obviously, something goes wrong when I fire ZendSkeletonApplication, and I get the following when hit the following URL: http://www.myDevServer.com/skeleton/public/ Fatal error: Uncaught exception 'RuntimeException' with message 'Unable to load ZF2. Run `php composer.phar install` or define a ZF2_PATH environment variable.' in /var/www/skeleton/init_autoloader.php:48 Stack trace: #0 /var/www/skeleton/public/index.php(9): include() #1 {main} thrown in /var/www/skeleton/init_autoloader.php on line 48 I have skimmed through the docs, tutorials and the like, but there are no straight forward answer to this kind of configuration. In the official doc, in the (very short) installation chapter, I see a reference to adding an include path in PHP. But no example... http://zf2.readthedocs.org/en/latest/ref/installation.html Once you have a copy of Zend Framework available, your application needs to be able to access the framework classes found in the library folder. Though there are several ways to achieve this, your PHP include_path needs to contain the path to Zend Framework’s library. But then, when I get to the "Getting Started" chapter, it's all composer.phar and nothing else... http://zf2.readthedocs.org/en/latest/user-guide/skeleton-application.html I'm no sysAdmin, just a Zend enthusiast. I'm pretty sure this PEBKAC problem might be obvious for those who already got in ZF2 previous betas. Thanks for helping my out. EDIT: Problem was resolved, thanks to Daniel M. Just setting up ZF2_PATH in httpd.conf was all that was needed. SetEnv ZF2_PATH /var/ZF2 I also removed the include_path reference in php.ini and everything works just fine. So I have no idea why Zend suggested to include it there in their official docs.

  • What's the appropriate way to upgrade Apache in RHEL?

    - by jldugger
    The version of Apache shipped in RHEL 5.4 is very old. A feature I need only shipped recently. It seems Apache upstream only ships tarballs, and omits binary packages. Obviously I could build from source, but what's the canonical way to upgrade a single package like this? Is it common procedure to drop a newer tarball in the existing SPEC, or does someone already do all this with an eye towards RHEL?

  • How can I customize my bootloader to make it prettier?

    - by Matthew
    I hate how when I turn on the computer it just (after the hp logo, which I hate having also), shows white text on a black background. I'm wondering if there's easy ways to customize this (I'm choosing between Windows 7 and two separate Ubuntu 10.10 installs). I've read a little about some complicated ways to do this, but is there not some simpler ways by installing a package on ubuntu or something? I don't want to hack a bunch of code together to get a simple effect. I'm hoping for actual images and having like the windows 7 logo and ubuntu logo to choose from. Ideas?

  • MySQL won't start, reinstall fails on Ubuntu 12.04

    - by Evils
    My problem started yesterday night when I tried to change the my.cnf config on my ubuntu 12.04 x64 System. I simply tried to changed the bind-address parameter from 127.0.0.1 to 0.0.0.0. A simple restart after a reboot gave this error: stop: Unknown instance: start: Job failed to start I tried to start mysql then by using 'mysqld' which outputs this: 130701 11:05:59 [Note] Plugin 'FEDERATED' is disabled. mysqld: Table 'mysql.plugin' doesn't exist 130701 11:05:59 [ERROR] Can't open the mysql.plugin table.

  • Audio is working, but the speaker test doesn't work

    - by Pacquo
    I've installed Ubuntu 12.04 LTS from a minimal cd on a netbook (Asus 1001 PXD). I've installed the ubuntu-desktop package using the --no-install-recommends option. Everything works fine, except the "sound test" for headphones or analog speakers. Clicking on the "test" buttons (front left and front right) I don't hear any sound. Despite this, the audio is working properly. I've checked the audio levels with alsamixer; I have also checked that the test sounds actually exist in /usr/share/sounds/alsa. I tried an installation of Ubuntu 12.04 LTS made with the desktop-cd, and in this case the speaker test works properly. I suppose, therefore, that the problem could depend on the lack of a package, but I have not identified which one.

  • Access to my files on Android

    - by user18644
    I am thinking of subscribing to Dropbox which is slightly more costly than Ubuntu one but I need access to my files on the go, and I prefer to use my smartphone to my netbook most of the time as I like to travel light. I do not want to stream music, I want access to my files only. Whereas there is a free app for Dropbox to access said files, there isn't one for Ubuntu. I would be prepared to wait a while if you have got this in hand, have you actually given this any thought? Please tell me whether I should ignore Ubuntu One and link up with Dropbox?

  • MySQL died during the night on a 12.04.1 Ubuntu

    - by Olivier
    I can't explain why, but somehow during the night, one of my MySQL running on an Ubuntu 12.04.1 box broke. The service is running but I can't login anymore (to SQL), the previous password is not working anymore. It does not looks like the server has been compromised (nothing in /var/auth.log) It looks like some automatic security upgrade (server is configured to perform those) has occured and broke something. The MySQL server has restarted a couple of times in the logs at the time errors started to happen (I get email when CRON task fail). In the logs it complains about an unset root password (I do have cron job running all day using SQL so the password was set & working for months). Anyway I can't login without password either! Do you have any idea of what could have happened? How do I get my databases back? This line looks strange : Nov 6 06:36:12 ns398758 mysqld_safe[6676]: ERROR: 1064 You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near 'ALTER TABLE user ADD column Show_view_priv enum('N','Y') CHARACTER SET utf8 NOT ' at line 1 Here is the full log below : Nov 6 06:36:06 ns398758 mysqld_safe[6586]: Nov 6 06:36:06 ns398758 mysqld_safe[6586]: PLEASE REMEMBER TO SET A PASSWORD FOR THE MySQL root USER !

  • Upgrade to 2008 R2

    - by DavidWimbush
    I don't like it, Carruthers. It's just too quiet. Well, I've done the pre-production server, the main live server and the Reporting/BI server with remarkably little trouble. Pre-production and live were rebuilds. I failed live over to our log shipping standby for the duration, which has a gotcha I blogged about before. When I failed back to the primary live server again, it was very quick to bring the databases online. I understand the databases don't actually get upgraded until you recover them but there was no noticable delay. It's gone from 2005 Workgroup - limited to 4GB of memory - to 2008 R2 Standard so it can now use nearly all of the 30GB in the server. It's soo much faster. The reporting/BI server I upgraded in situ. This took a while but, again, went smoothly. Just watch out, because the master database was left at compatibility level 90. Also the upgrade decided to use the reporting service's credentials for database access when running reports. It didn't preserve the existing credentials and I had to go into the Reporting Configuration Manager to put them back in. Make sure you know what credentials your server is using before you upgrade. All things considered, a fairly painless experience. Now I just have to upgrade and reset our log shipping standby server again!
