  • Distributed, Parallel, Fault-tolerant File System

    - by Eddified
    There are so many choices that it's hard to know where to start. My requirements are these: Runs on Linux Most of the files will be between 5-9 MB in size. There will also be a significant number of small-ish jpgs (100px x 100px). All of the files need to be available over http. Redundancy -- ideally it would provide the space efficiency similar to RAID 5 of 75% (in RAID 5 this would be calculated thus: with 4 identical disks, 25% of the space is used for parity = 75% efficent) Must support several petabytes of data scalable runs on commodity hardware In addition, I look for these qualities, though they are not "requirements": Stable, mature file system Lots of momentum and support etc I would like some input as to which file system works best for the given requirements. Some people at my organization are leaning towards MogileFS, but I'm not convinced of the stability and momentum of that project. GlusterFS and Lustre, based on my limited research, appear to be better supported... Thoughts?

  • Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not a "handsome prince"!

    - by Jim Dobbs
    Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

  • Is it possible to convert striped logical volume to linear logical volume?

    - by JooMing
    I've a logical volume that is striped across three physical volumes. I had to move this logical volume to another physical volume. This worked nicely with pvmove command. However, I discovered later that the logical volume is still striped and now all three stripes are on the same physical volume. Is there any way to convert striped logical volumes to linear logical volumes? I'm using LVM2 on linux. I figured that the obvious possibility is to rename the striped logical volume, create a new linear logical volume, and then copy data over, but that requires taking the filesystem system offline for some time. Unfortunately, I can't do that before the next week. Is there any better alternative?

  • Sending UDP/514 data magically appears in syslog without rsyslog running

    - by ale
    I’m using a programming language without a library to log to rsyslog over UDP. I thought I was going to need to write a library but I discovered something weird. If I send data on UDP/514 with the port open on the server then the data appears in the server’s syslog. rsyslogd isn’t running so syslog isn’t doing this. Data doesn’t get formatted into a syslog message so rsyslogd really isn’t doing this (only raw text enters syslog). Linux must see the data coming in on this port and know that it should go into /var/log/messages? If I do the same on another port (e.g. UDP/515) then nothing appears in the log! What is doing this? Some CentOS feature? The kernel?

  • Reverse bash console text flow

    - by radman
    Hi, This is a bit of a weird question and I'm not sure that there is any easy answer to it but I am very interested in finding a solution. So when I work on a linux machine via a console I find that I am constantly staring at the bottom of the screen, as once you have executed a bunch of commands text fills toward the bottom. Now I find that this is decidedly not good for my neck and it would be far better if instead of scrolling to the bottom, the text would scroll to the top instead. So does anyone out there know if there is a way to reverse the direction text appears in a console? (note that i am aware of the clear command) Example: default behaviour user@machine:~$ command 1 user@machine:~$ command 2 user@machine:~$ command 3 user@machine:~$ __active_prompt__ desired behaviour user@machine:~$ __active_prompt__ user@machine:~$ command 3 user@machine:~$ command 2 user@machine:~$ command 1 Running Kubuntu 10.04 using Konsole I realise this is an odd question, thanks for any help.

  • information about /proc/pid/sched

    - by redeye
    Not sure this is the right place for this question, but here goes: I'm trying to make some sense of the /proc/pid/sched and /proc/pid/task/tid/sched files for a highly threaded server process, however I was not able to find a good explanation of how to interpret this file ( just a few bits here: http://knol.google.com/k/linux-performance-tuning-and-measurement# ) . I assume this entry in procfs is related to newer versions of the kernel that run with the CFS scheduler? CentOS distro running on a 2.6.24.7-149.el5rt kernel version with preempt rt patch. Any thoughts?

  • MySQL Daemon failed to start

    - by T. Brian Jones
    THE SETUP I'm running Linux CentOS on an Amazon EC2 instance. The MySQL data files are on an EBS Drive mounted at /data/ ( symlink - /var/lib/mysql /data/mysql ). Everything works fine in this setup. THE PROBLEM I'm trying to move everything from this EBS drive to a new drive. I umounted the /data/ drive, and mounted it at /data2/. Then I mounted the new drive at /data/ and copied everything over to it from /data2/. Everything on the system works great, except MySQL. Every time I try to start the MySQL daemon ( /etc/init.d/mysqld start ) I get a MySQL Daemon failed to start error.

  • Which window manager do you use?

    - by Stephan202
    Combining "What is your default web browser?" and "What are the differences between Linux Window Managers", I ask you: which window manager do you use, and why? Myself I prefer a minimal window manager on the one hand (in the past I used Fluxbox), but on the other hand wish to go with the main stream, to ease finding (Googling) solutions in case of problems. Hence I stick with Gnome as it is shipped with Ubuntu. Why do you use the window manager which you use? I understand some reasons may be subjective, but please try to cite technical reasons where possible.

  • environment variable issue in shell

    - by George2
    I am using Red Hat Linux Enterprise 5. I know the theory that -- using export to set environment variable, the environment variable will apply to current and child environment, but without using export to set environment variable, the environment variable will only apply to the current environment. My confusion is, what is the exact definition of "child environment" and "current environment"? For example, $ var1=123 $ echo "Hello [$var1]" the value of var1 (which is 123) is printed in shell, but I think echo is a command invoked by current shell, and it (the echo command) should be a child environment of current shell and the value of var1 should not (because not using export var1=123) impact echo. Any comments? Thanks in advance!

  • Partial Submit vs. Auto Submit

    - by Frank Nimphius
    Partial Submit ADF Faces adds the concept of partial form submit to JavaServer Faces 1.2 and beyond. A partial submit actually is a form submit that does not require a page refresh and only updates components in the view that are referenced from the command component PartialTriggers property. Another option for refreshing a component in response to a partial submit is call AdfContext.getCurrentInstance.addPartialTarget(component_instance_handle_goes_here)in a managed bean. If a form contains required fields that the user left empty invoking the partial submit, then errors are shown for each of the field as the full form gets submitted. Autosubmit An input component that has its autosubmit property set to true also performs a partial submit of the form. However, this time it doesn't submit the entire form but only the component that triggers the submit plus components referenced it in their PartialTriggers property. For example, consider a form that has three input fields inpA, inpB and inpC with autosubmit=true set on inpA and required=true set on inpB and inpC. use case 1: Running the view, entering data into inpA and then tabbing out of the field will submit the content for inpA but not for inpB and inpC. Further more, none of the required field settings on inpB and inpC causes an error. use case 2: You change the configuration of inpC and set its PartialTriggers property to point to the ID of component inpA. When rerunning the sample, entering a value into inpA and tabbing out of the field will now submit the inpA and inpC fields and thus show an error for the missing required value on inpC. Internally, using autosubmit=true on an input component sets the event root to just this field, which good to have in case of dependent field validation or behavior. The event root can extended to include other components by using the Partial Triggers property on these components to point to the input field that has autosubmit=true defined. PartialSubmit vs. AutoSubmit Partial submit set on a command component submits the whole form and leaves it to the developer to decide which UI component is refreshed in response. Client side required field validation (as well as the server side equivalent) is not disabled by executed in this scenario. Setting immediate=true on the command item to skip validation doesn't help as it would also skip the model update. Auto submit is a functionality on the input components and also performs a partial form submit. However, in addition an event root is defined that narrows the scope for the submitted data and thus the components that are validated on the request.

  • Watch Flash video but block out part of it

    - by Ken
    I'm learning a foreign language. There are several online sites that have Flash video in the language I'm learning (e.g., Hulu), which is great. Unfortunately, they have English subtitles, which is (depending on who you ask) somewhere between "annoying" and "actively harmful to my learning". When I'm watching them in a window, I can just move them near the bottom of the screen, or put another window over them. That's awkward, but it kind of works. But I'd like to watch them full-screen, on my TV set. Full-screen Flash doesn't let me put any window on top of it. Is there a way to watch an online Flash video but block out part of it? I'll probably be using my Mac for this, but maybe Linux -- solutions for either one welcome.

  • Measuring cumulative network statistics per user or per process

    - by zsimpson
    I've been googling for hours -- Under Linux I want to know the cumulative bytes sent and received by user or by process over all ip protocols. The best I've found in my searches is that it's possible to use iptables to mark packets for a user, for example: iptables -t mangle -A OUTPUT -p tcp -m owner --uid-owner test -j MARK --set-mark 1 It appears that "tc" can then shape traffic with that but I just want the statistic -- I don't want to shape the traffic. I want something like: "user U has transmitted used XMB since time Y". I can't figure out how to get statistics from these marked packets. Also, I've looked at nethogs but they seem to be measuring the instantaneous flow and I need cumulative counts. Anyone have ideas?

  • Kickstart virtual console: No 'Shell prompt' at Alt-F2

    - by Stefan Lasiewski
    I am installing Scientific Linux 6.1 via kickstart, and I am trying to debug a problem. According to Tips and tricks for anaconda and kickstart, I should have several virtual consoles available: What the different terminals display Alt-F1 The installation dialog when using text or cmdline Alt-F2 A shell prompt Alt-F3 The install log displaying messages from install program Alt-F4 The system log displaying messages from kernel, etc. Alt-F5 All other messages Alt-F7 The installation dialog when using the graphical installer The Virtual Consoles Alt-F1, F3, F4 & F5 all work and show various logging information. However, the Virtual Console at Alt-F2 does not do anything. I could really use access to the shell prompt (Alt-F2), however there is no Shell prompt available at the second virtual console (Alt-F2). All I have is a blinking '_'. Can I forge Alt-F2 to show me a shell prompt?

  • Subversion hooks no longer running

    - by Chris Lieb
    I don't know when this started happening, but, for some reason, none of my Subversion hooks are running anymore. I am running Subversion 1.6.9 on a Gentoo Linux machine, which has had its hooks work in the past. I am running Subversion through the svn_dav module for Apache2.2. I modified the hook scripts that I make use of to write into a file in the /tmp directory owned by apache:apache whenever they are executed, but after making a commit, there is nothing in the file that should be written to. The scripts are executable and owned by apache:apache, so I don't think that is the issue. Here is one of my test scripts (post-commit.sh) that isn't getting executed: #!/bin/sh /bin/echo post-commit >> /tmp/z_test exit 0 After running a commit, I expect both the pre-commit.sh and post-commit.sh hooks to be run, but neither of them appear to be writing into the desired file (/tmp/z_test). What's going on?

The key to mastery is how architects approach design, what they value, and where they focus their attention and work." As retail dies, whom will be the winners? | Peter Evans-Greenwood "The problem for many retailers is that how consumers shop has changed but the the retailers haven't adapted, " says Peter Evans-Greenwood. "Their sole virtue was to be the last step in a supply chain delivering somebody else's products to the consumer. However, being the last step in the supply chain is no longer a virtue when consumers skip across channels and can reach around the globe, no longer dependant on or limited to what they can find locally." Thought for the Day "Brains require stimulation. If you're locked into a pattern of work, work, and more work, your brain soon habituates - the same way that it lets you stop hearing a clock ticking.

  • How to control fan speed on Compaq Presario under Ubuntu?

    - by Josh
    I have a Compaq Presario R4000 running Ubuntu Linux 9.10 karmic. The system runs very hot and one of the fans is wither never running or always running at the slowest speed. For a while I thought the fan was dead but I just updated the BIOS (Phoenix BIOS) and during the update, that fan suddenly kicked in at full speed! How can I get that fan to spin up during normal usage? I have tried sensores-detect but all it found was k8temp, no fans... (SpeedFan under windows found no fans either)

  • Is there any way to limit my Internet connection to a per program basis?

    - by Igoru
    My Linux connection is REALLY free. I live in Brazil, so where I live I can only have 1 Mbit/s. Yes I know it's sad, but it's not the point. Everytime I'm updating my Ubuntu 9.04 or downloading something, it does eat all my bandwidth. Like, while update-manager is downloading the packages, I can see by netspeed applet in my panel that the incoming traffic goes to 110 kB/s. And then, my Emesene suddenly goes disconnected, and I can't navigate. As you can imagine, I can't use my Internet connection again until the packages are all downloaded or I cancel the update in the middle. As I said, same thing happens when I'm dowloading something, but less intrusive and immediate. The question is: is there any way to limit that APT/downloads traffic to some way I can still use my other Internet services, or to reserve some bandwidth for common navigation tasks (like we have on Windows, but I forgot this thing's name, it's like "something packages".

  • May the file size returned by stat be compromised?

    - by codeholic
    I want to make sure that nobody changed a file. In order to accomplish that, I want not only to check MD5 sum of the file, but also check its size, since as far as I understand this additional simple check can sophisticate falsification by several digits. May I trust the size that stat returns? I don't mean if changes were made to stat itself. I don't go that deep. But, for instance, may one compromise the file size that stat returns by hacking the directory file? Or by similar means, that do not require superuser privileges? It's Linux.

  • Gauging Maturity of your BPM Strategy - part 1 / 2

    - by Sanjeev Sharma
    Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin:0in; mso-para-margin-bottom:.0001pt; mso-pagination:widow-orphan; font-size:10.0pt; font-family:"Times New Roman","serif";} In this post I will discuss the essence of maturity assessment and the business imperative for doing the same in the context of BPM. Social psychology purports that an individual progresses from being a beginner to an expert in a given activity or task along four stages of self-awareness: Unconscious Incompetence where the individual does not understand or know how to do something and does not necessarily recognize the deficit and may even deny the usefulness of the skill. Conscious Incompetence where the individual recognizes the deficit, as well as the value of a new skill in addressing the deficit. Conscious Competence where the individual understands or knows how to do something but demonstrating the skill requires explicit concentration. Unconscious Competence where the individual has had so much practice with a skill that it has become "second nature" and serves as a basis of developing other complementary skills. We can extend the above thinking to an organization as a whole by measuring an organization’s level of competence in a specific area or capability, as an aggregate of the competence levels of individuals it is comprised of. After all organizations too like individuals, evolve through experience, develop “memory” and capabilities that are shaped through a constant cycle of learning, un-learning and re-learning. Hence the key to organizational success lies in developing these capabilities to enable execution of its strategy in-line with the external environment i.e. demand, competition, economy etc. However developing a capability merits establishing a base line in order to Assess the magnitude of improvement from past investments Identify gaps and short-comings Prioritize future investments in the right areas A maturity assessment is essentially an organizational self-awareness check that is aimed at depicting the “as-is” snapshot of an existing capability in-order to guide future investments to develop that capability in-line with business goals. This effectively is the essence of a maturity Organizational capabilities stem through its architecture, routines, culture and intellectual resources that are implicitly and explicitly embedded in its business processes. Given that business processes underpin realization of organizational capabilities, is what has prompted business transformation and process management efforts. Thus, the BPM capability of an organization needs to be measured on an on-going basis to ensure delivery of its planned benefits. In my next post I will describe Oracle’s BPM Maturity assessment methodology.

  • Simplest way to expose UNIX mailboxes via IMAP or POP3 on RHEL 5.6

    - by db2
    We've got a web server running RedHat Enterprise Linux 5.6, and it has all the usual local UNIX mailboxes. As is typical, the root mailbox gets all the cron output, logwatch results, etc. I'd like an easier way to keep an eye on this mailbox besides running mail via ssh. What should I install/enable to allow access to these system mailboxes via IMAP or POP3 with minimal fuss? Either protocol would be fine for what I'm doing, as I could then add it as an account in Outlook. A bit of searching led me to cyrus-imapd and dovecot, but it seems like they are meant for more serious mail hosting operations. Either they use their own mailbox system exclusively, or don't have a simple way of making the UNIX mailboxes available. If I'm wrong about that, then I'm fine with using either of them as long as I can get to the mailboxes of the existing accounts on the box.
