  • DRBD stacked resources: recovering from failure

    - by Marcus Downing
    We're running a stacked four-node DRBD setup like this: A --> B | | v v C D This means three DRBD resources running across these four servers. Servers A and B are Xen hosts running VMs, while servers C and D are for backups. A is in the same datacentre as C. From server A to server C, in the first datacentre, using protocol B From server B to server D, in the second datacentre, using protocol B From server A to server B, different datacentres, stacked resource using protocol A First question: booting a stacked resource We haven't got any vital data running on this setup yet - we're still making sure it works first. This means simulating power cuts, network outages etc and seeing what steps we need to recover. When we pull the power out of server A, both resources go down; it attempts to bring them back up at next boot. However, it only succeeds at bringing up the lower-level resource, A-C. The stacked resource A-B doesn't even try to connect, presumably because it can't find the device until it's a connected primary on the lower level. So if anything goes wrong we need to manually log in and bring that resource up, then start the virtual machine on top of it. Second question: setting the primary of a stacked resource Our lower-level resources are configured so that the right one is considered primary: resource test-AC { on A { ... } on C { ... } startup { become-primary-on A; } } But I don't see any way to do the same with a stacked resource, as the following isn't a valid config: resource test-AB { stacked-on-top-of test-AC { ... } stacked-on-top-of test-BD { ... } startup { become-primary-on test-AC; } } This too means that recovering from a failure requires manual intervention. Is there no way to set the automatic primary for a stacked resource?

  • jquery creating stacked bar chart with flot?

    - by KittyYoung
    I'm using jquery flot and I'm trying to create a stacked bar chart, but I'm having some syntax issues... I'll post my code at the end of this, but I'm quite certain it's wrong. I do get a stacked bar chart, but there's only three columns... Basically, here is the data that I'm working with and what I want to accomplish... The first group (Focus Group 1) on each line is the bottom bar of the stacked bar, the second group (Focus Group 2) is the second, and the third group (Focus Group 3) is the top group. The "Responses" are what I want to use on the x-axis, the first number in each set is x, and the second number is y. Response1, [0, 0], [0,0], [0,9] Response2, [1, 5], [1,5], [1,11] Response3, [2, 2], [2,0], [2,8] Response4, [3, 1], [3,2], [3,6] Response5, [4, 0], [4,0], [4,7] I should also mention, that I'm not sure if a stacked chart is the best way to go... Admittedly, I'm not a very visual person, and generally find charts annoying... If there's a better way to present this data, then I am so totally open to suggestions... Essentially... I have a series of questions. Each of these questions were presented to three focus groups. Members of the focus groups selected a response. I'm trying to present the count per response, per focus group, for each question. I thought that a stacked chart would be the best way to go, but again, I'm open to other ways of doing this. The only thing is, I definitely need a visual representation of the data....

  • Stacked Launcher Item Double Click Behaviour on Alt-tab

    - by Brandon Bertelsen
    Let's say that you have multiple firefox windows open. What you see happen is an additional arrow points to it's icon in the launcher. However, if you double click the icon, it displays all of the windows in a spread out fashion, similar to the behaviour from pushing Super + W, but only for that program group. Is it possible to make this window spreading behaviour occur with alt-tab? PS: No idea what tags I should use, or if the language (jargon) in the title or question is appropriate.

  • Excel - add target line to stacked bar chart

    - by Chris W
    I've got a stacked bar chart. I'm displaying a set of floating bars to represent hi/low ranges for some metrics, by using a transparent fill on the bottom section of the bar I achieve the desired look. What I now need to do is add a horizontal line across the chart to indicate how a particular users score relates to all of these hi/low ranges therefore the placement of this line needs to be dynamic based on a value in a cell. Is there anyway to do this as I can't find an easy option. If this was a simple bar chart I could add the target scores as new series and use the line chart type but I don't seem able to overlay a second series on the stacked bar chart. I'm using 2003 at the moment but run this in 2007 if that helps.

  • Show all series' values in stacked bars mouseover (ASP.NET CHART)

    - by Dynde
    Hi... I'm using the asp.net Chart control to present a stacked bars chart. I can create a mouseover custom tooltip using this code: series.MapAreaAttributes = "onmouseover=\"showTooltip('#VALY');\""; ... which works fine. But I can't seem to find a way to show the rest of the values for the other series in that column. Example: I have 2 series (Paid and Unpaid) making up a single column in the chart. When I mouseover any of the series, I want to show both the value of the moused-over series, but also the other series contained in that particular stacked column. Can anyone point me in the right direction?

  • Turning A Stacked List into workable data

    - by BoSox
    In Excel I have a list of names that in the cell appear stacked, and I want each name in its own column. I was thinking Python may be a good way to do this? Example: Joe Smith John Hawk Mike Green Lauren Smith One cell will look exactly like that, with each name on its line within the cell but all of the names contained in the cell. I have 50 cells each with 1-20 stacked names and I want to put each name in its own cell on a given row. So, in my example all of those names would occupy the same row but each would have their own column. Any ideas?

  • Excel graph: turn stacked bar chart into part bullet chart

    - by Mike
    I've a simple data file that has one column of actuals and another of target against categories. I would like to turn the TARGET figure into a 'Bullet marker'. I've seen it done on other graphs but I'm struggling with the category column being overwritten with the xy axis values. Or if I get close to doing it then the xy markers are not central. I've checked out Peltier but his examples are based on even more comlicated data than mine, so the steps required didn't seem to match up. Help greatly appreciated. Thanks Mike. Example Data: Cat Actual target A 10 15 B 10 12 C 20 17

  • Create two semi-transparent images that when stacked produce the target image

    - by posfan12
    Due to CSS limitations I am forced to stack to semi-transparent images on my website. I won't go into detail regarding the CSS since if I can get this question answered the problem is moot. Anyway, I would like to modify image A in the GIMP such that it will look like it did originally after being stacked on top of image B. Both image A and image B have their opacities set to 50%. Image B is a solid color throughout, whereas image A has some minor details such as a gradient. Here's what it looks like before image B is applied on top (and what it should look like in the end): [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_target_image.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_target_image.png[/IMG][/URL] Here's what it looks like after image B has been applied on top: [URL=http://s421.photobucket.com/albums/pp292/SharkD2161/Support/Website/?action=view&current=website_testing_undesired_result.png][IMG]http://i421.photobucket.com/albums/pp292/SharkD2161/Support/Website/th_website_testing_undesired_result.png[/IMG][/URL] Thanks!

  • Stacked up with web service configuration

    - by Allan Chua
    I'm currently stacked with the web service that im creating right now. when Testing it in local it all works fine but when I try to deploy it to the web server it throws me the following error An error occurred while trying to make a request to URI '...my web service URI here....'. This could be due to attempting to access a service in a cross-domain way without a proper cross-domain policy in place, or a policy that is unsuitable for SOAP services. You may need to contact the owner of the service to publish a cross-domain policy file and to ensure it allows SOAP-related HTTP headers to be sent. This error may also be caused by using internal types in the web service proxy without using the InternalsVisibleToAttribute attribute. Please see the inner exception for more details. here is my web config. <?xml version="1.0"?> <configuration> <configSections> </configSections> <system.webServer> <modules runAllManagedModulesForAllRequests="true"> </modules> <validation validateIntegratedModeConfiguration="false" /> <security> <requestFiltering> <requestLimits maxAllowedContentLength="2000000000" /> </requestFiltering> </security> </system.webServer> <connectionStrings> <add name="........" providerName="System.Data.SqlClient" /> </connectionStrings> <appSettings> <!-- Testing --> <add key="DataConnectionString" value="..........." /> </appSettings> <system.web> <compilation debug="true" targetFramework="4.0"> <buildProviders> <add extension=".rdlc" type="Microsoft.Reporting.RdlBuildProvider, Microsoft.ReportViewer.WebForms, Version=10.0.0.0, Culture=neutral, PublicKeyToken=b03f5f7f11d50a3a" /> </buildProviders> </compilation> <httpRuntime executionTimeout="1200" maxRequestLength="2000000" /> </system.web> <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true" multipleSiteBindingsEnabled="true" /> <behaviors> <serviceBehaviors> <behavior name="Service1"> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="2000000000" /> </behavior> <behavior name=""> <serviceMetadata httpGetEnabled="true" /> <serviceDebug includeExceptionDetailInFaults="false" /> </behavior> <behavior name="nextSPOTServiceBehavior"> <serviceMetadata httpsGetEnabled="true"/> <serviceDebug includeExceptionDetailInFaults="true" /> <dataContractSerializer maxItemsInObjectGraph="2000000000" /> </behavior> </serviceBehaviors> </behaviors> <bindings> <basicHttpBinding> <binding name="SecureBasic" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="Transport" /> <readerQuotas maxArrayLength="2000000" maxStringContentLength="2000000"/> </binding> <binding name="BasicHttpBinding_IDownloadManagerService" closeTimeout="00:10:00" openTimeout="00:10:00" receiveTimeout="00:10:00" sendTimeout="00:10:00" maxBufferSize="2147483647" maxReceivedMessageSize="2147483647"> <security mode="Transport" /> </binding> </basicHttpBinding> </bindings> <services> <service behaviorConfiguration="nextSPOTServiceBehavior" name="NextSPOTDownloadManagerWebServiceTester.Web.WebServices.DownloadManagerService"> <endpoint binding="basicHttpBinding" bindingConfiguration="SecureBasic" name="basicHttpSecure" contract="NextSPOTDownloadManagerWebServiceTester.Web.WebServices.IDownloadManagerService" /> <!--<endpoint binding="basicHttpBinding" bindingConfiguration="" name="basicHttp" contract="NextSPOTDownloadManagerWebServiceTester.Web.WebServices.IDownloadManagerService" />--> <!--<endpoint address="" binding="basicHttpBinding" bindingConfiguration="BasicHttpBinding_IDownloadManagerService" contract="NextSPOTDownloadManagerWebServiceTester.Web.WebServices.IDownloadManagerService" /> <endpoint address="mex" binding="mexHttpsBinding" contract="IMetadataExchange" />--> </service> </services > </system.serviceModel> </configuration>

  • Incorrect rendering in dojox charting stacked column?

    - by FokeyJoe
    Hiya, I seem to be having a problem with my dojo stackedcolumn whereby the scale of some of the bars is correct for some x-axis points, but not others. Here's my code (observe the northern ireland hydro should be 70, but only shows as around 30): dojo.addOnLoad(function() { var chart1 = new dojox.charting.Chart2D("sitesbycountry"); chart1.addPlot("default", {type: "StackedColumns", gap: 10}); chart1.addPlot("horzgrid", {type: "Grid", hMajorLines: true, vMajorLines: false}); chart1.addAxis("x", {labels: [{value: 1, text: 'Northern Ireland'}, {value: 2, text: 'Wales'}, {value: 3, text: 'Scotland'}, {value: 4, text: 'England'}], minorTicks: false, microTicks: false}); chart1.addAxis("y", {vertical: true, minorTicks: false, microTicks: false}); chart1.addSeries("Hydro", [70, 53, 198, 102], {fill: "#ddddff"}); chart1.addSeries("Wind and Wave", [67, 51, 150, 245], {fill: "#FEFFBF"}); chart1.addSeries("Landfill", [1, 23, 40, 0], {fill: "#CFFFD1"}); chart1.addSeries("Other Biofuels and Wastes", [4, 3, 11, 66], {fill: "#DFD2C3"}); chart1.render(); }); Is this a behaviour of the chart that I'm not aware of? TIA FokeyJoe

  • Three vertically stacked DIVs with scrolling middle

    - by Dave
    Is it possible to stack three DIVs vertically and have just the middle div scroll vertically? I don't want to use pixel heights, though, because the DIVs are inside of a dialog box that is resizeable. Something like this (pardon my lousy ASCII art): +-----------+ | Header | +-----------+ | ^| | || | Scroll || | || | v| +-----------+ | Footer | +-----------+ The goal is to have the header and and footer fixed and, as the dialog grows, the middle div would grow vertically. Maybe I'm just being stupid, but I've been fighting this for the last few hours and can't seem to get it right. The three DIVs probably need to be inside "another" DIV but when I do that, and set the height to 100%, it grows as the middle DIV grows. Again, it's probably something silly I'm not accounting for. I've also tried using a TABLE to no avail. Thanks for any help.

  • iPhone Input with Stacked Views

    - by Forrest
    Hi, I've got a situation in an iphone application where buttons are not receiving input as I expect. Here's the setup: ViewMain - The main view full of various images and labels ViewOverlay - A HUD like overlay view with two UIButton objects. To create my scene I do the following: viewController.view = ViewMain [ViewMain addsubview:ViewOverlay] This view renders as expected, with ViewOverlay correctly rendered ontop of ViewMain. However the two buttons found inside ViewOverlay do not receive touch events and can not be pressed. Tapping them does nothing at all. I very well may be going about this in the entirely wrong direction. Any ideas?

  • Hide TabControl buttons to manage stacked Panel controls

    - by Luca
    I need to handle multiple panels, containing variuous data masks. Each panel shall be visible using a TreeView control. At this time, I handle the panels visibility manually, by making the selected one visible and bring it on top. Actually this is not much confortable, especially in the UI designer, since when I add a brand new panel I have to resize every panel and then design it... A good solution would be using a TabControl, and each panel is contained in a TabPage. But I cannot find any way to hide the TabControl buttons, since I already have a TreeView for selecting items. Another solution would be an ipotethic "StackPanelControl", where the Panels are arranged using a stack, but I couldn't find it anywhere. What's the best solution to handle this kind of UI?

  • Agile version control?

    - by Paul Dixon
    I'm trying to work out a good method to manage code changes on a large project with multiple teams. We use subversion at the moment, but I want more flexibility in building a new release than I seem to be able to get with subversion. Here's roughly I want: for each developer to create easily identifiable patches for the project. Each patch delivers a complete user story (a releasable feature or fix). It might encompass many changes to many files. developers are able to easily apply and remove their own and other patches to facilitate testing release manager selects the patches to be used in the next release into a new branch branch is tested, fixes merged in, and ultimately merged into live teams can then pull these changes back down into their sandboxes. I'm looking at stacked git as a way of achieving this, but what other tools or techniques can deliver this sort of workflow?
