  • Software RAID 1 Configuration

    - by Corve
    I have created a software RAID 1 quite some while ago and it always seemed to work for me. However I am not completely sure that I have configured everything right and do not have the experience to check so I would be very grateful for some advice or just verification that all seems right so far. I am using Linux Fedora 20 (32 bit with plans to upgrade to 64bit) The RAID 1 should consist of two 1TB SATA hard drives. This is the output of mdadm --detail /dev/md0 /dev/md0: Version : 1.2 Creation Time : Sun Jan 29 11:25:18 2012 Raid Level : raid1 Array Size : 976761424 (931.51 GiB 1000.20 GB) Used Dev Size : 976761424 (931.51 GiB 1000.20 GB) Raid Devices : 2 Total Devices : 1 Persistence : Superblock is persistent Update Time : Sat Jun 7 10:38:09 2014 State : clean, degraded Active Devices : 1 Working Devices : 1 Failed Devices : 0 Spare Devices : 0 Name : argo:0 (local to host argo) UUID : 1596d0a1:5806e590:c56d0b27:765e3220 Events : 996387 Number Major Minor RaidDevice State 0 0 0 0 removed 1 8 0 1 active sync /dev/sda The RAID is mounted successfully: friedrich@argo:~ ? sudo mount -l | grep md0 /dev/md0 on /mnt/raid type ext4 (rw,relatime,data=ordered) Basically my question are: Why do I only have 1 active device? What does the State removed at bottom mean? Also I noticed some strange error messages that I see on the console on system start and shutdown and always repeating in the background when I switch with Ctrl + Alt + F2: ... ata2: irq_stat 0x00000040 connection status changed ata2: SError: { CommWake DevExch } ata2: COMRESET failed (errno=-32) ata2: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen ata2: irq_stat 0x00000040 connection status changed ata2: SError: { CommWake DevExch } ata2: exception Emask 0x10 SAct 0x0 SErr 0x4040000 action 0xe frozen ... Are these errors related to the RAID? Something seems wrong with the SATA devices.. All together the system works (I can read and write to the mounted raid) but I always had these strange errors on startup shutdown (probably always in the background). Thx for your help

  • Nagios DNX plugins

    - by danneh3826
    I'm toying with the idea of multiple Nagios instances setup to monitor our infrastructure. I've looked at all the various methods of distributed Nagios checks, and I think DNX comes out the closest. DNX handles failure of worker nodes, that's fine. What happens if the main DNX server fails though? Is there a way to replicate the server too? I'm using AWS EC2 primarily, so I can utilise Elastic Load Balancing for the web UI, but I need to be able to handle the AZ where the monitoring server is to fail over, and essentially for a second to pick up the checking load (active/passive, active/active, so long as it doesn't fail completely) The other thing I'm trying to solve is an issue with routing. What I'd like is to have multiple nodes report a fault before Nagios confirms it as critical. Not the NRPE checks, as they're pretty self explanitory, but things more like check_ping. I often have routing issues out of AWS to certain datacenters, so Nagios can often report bad/no ping/timeout as a critical issue, even though the machine in question is working fine. Would it be possible to have a setup where a worker complains a service check is critical, and have a second worker node (positioned in another datacenter/AZ) also report the service as critical before the Nagios central server issues a critical alert? I realise I might be asking a bit much (how far down the line do you go setting up failover systems before it starts to get ridiculous), however surely someone must have thought of this scenario when developing DNX?

  • iptables: How to combine DNAT and SNAT to use a secondary IP address?

    - by Que_273
    There are lots of questions on here about iptables DNAT/SNAT setups but I haven't found one that solves my current problem. I have services bound to the IP address of eth0 (e.g. 192.168.0.20) and I also have a IP address on eth0:0 (192.168.0.40) which is shared with another server. Only one server is active, so this alias interface comes and goes depending on which server is active. In order to get traffic accepted by the service a DNAT rule is used to change the destination IP. iptables -t nat -A PREROUTING -d 192.168.0.40 -p udp --dport 7100 -j DNAT --to-destination 192.168.0.20 I also wish all outbound traffic from this service to appear to come from the shared IP, so that return responses will work in the event of a active-standby failover. iptables -t nat -A POSTROUTING -p udp --sport 7100 -j SNAT --to-source 192.168.0.40 My problem is that the SNAT rule is not always run. Inbound traffic causes a connection tracking entry like this. [root]# conntrack -L -p udp udp 17 170 src=192.168.0.185 dst=192.168.0.40 sport=7100 dport=7100 src=192.168.0.20 dst=192.168.0.185 sport=7100 dport=7100 [ASSURED] mark=0 secmark=0 use=2 which means the POSTROUTING chain is not run and outbound traffic leaves with the real IP address as the source. I am thinking I can set up a NOTRACK rule in the raw table to prevent conntracking for this port number, but is there a better or more efficient way to make this work? Edit - Alternative question: Is there a way (in CentOS/Linux) to have an interface that can be bound to but not used, such that it can be attached to the network or detached when a shared IP address is swapped between servers?

  • Is it possible to theme Windows 7 like XP?

    - by LonelyPixel
    Everybody seems to mean the window frame colour and a set of desktop background pictures when they're talking about Windows 7 themes. Does anybody remember what themes used to be in Windows XP? You could actually alter the appearance of the window frame, how close buttons and menu popups looked, put a texture on the taskbar, all those funny things. Microsoft themselves have published a number of XP themes over time (Luna on XP, Royal on MCE2005, Zune later on). I don't say that most of those and the numerous third party XP themes were beautiful or even practical. But it was possible to create something nice. In Windows 7 (I suppress the existence of Windows Vista...) such a theme could well be used to increase readability to a level before Aero Glass again. I mean, you cannot really tell whether a Glass window is active or not. I've been tweaking the colours and transparency levels a lot recently but the only safe indicator is the close button: it's red when the window is active, it's colourless otherwise. Then there's the window title. It is always painted black, on however dark a background. Again, regardless of whether the window is active or not. Turning off Aero is not an option in Windows 7 anymore. Classic design looks just ugly there. It already wasn't exactly looking good on XP with the wide start menu. So, can we increase the readability of the Windows 7 UI with themes like in XP or didn't Microsoft learn a thing since the Windows 7 Preview "Vista"?

  • Update a list from another list

    - by Langali
    I have a list of users in local store that I need to update from a remote list of users every once in a while. Basically: If a remote user already exists locally, update its fields. If a remote user doesn't already exist locally, add the user. If a local user doesn't appear in the remote list, deactivate or delete. If a local user also appears in the remote list, update its fields. Just a simple case of syncing the local list. Is there a better way to do this in pure Java than the following? I feel gross looking at my own code. public class User { Integer id; String email; boolean active; //Getters and Setters....... public User(Integer id, String email, boolean active) { this.id = id; this.email = email; this.active = active; } @Override public boolean equals(Object other) { boolean result = false; if (other instanceof User) { User that = (User) other; result = (this.getId() == that.getId()); } return result; } } public static void main(String[] args) { //From 3rd party List<User> remoteUsers = getRemoteUsers(); //From Local store List<User> localUsers =getLocalUsers(); for (User remoteUser : remoteUsers) { boolean found = false; for (User localUser : localUsers) { if (remoteUser.equals(localUser)) { found = true; localUser.setActive(remoteUser.isActive()); localUser.setEmail(remoteUser.getEmail()); //update } break; } if (!found) { User user = new User(remoteUser.getId(), remoteUser.getEmail(), remoteUser.isActive()); //Save } } for(User localUser : localUsers ) { boolean found = false; for(User remoteUser : remoteUsers) { if(localUser.equals(remoteUser)) { found = true; localUser.setActive(remoteUser.isActive()); localUser.setEmail(remoteUser.getEmail()); //Update } break; } if(!found) { localUser.setActive(false); // Deactivate } } }

    Hi, Is there a way to access other active windows in AIR? I want to make an AIR app that look into the active application text and look for a specific pattern and make a transparent window into that text position to create a button. Its a bit like the skype plug-in in Mozilla ... It replaces the telephone number with a button to launch skype.

  • Linq To Sql Concat() dropping fields in created TSQL

    - by user191468
    This is strange. I am moving a stored proc to a service. The TSQL unions multiple selects. To replicate this I created multiple queries resulting in a common new concrete type. Then I issue a return result.ToString(); and the resulting SQL selects have varying numbers of columns specified thus causing an MSSQL Msg 205... using (var db = GetDb()) { var fundInv = from f in db.funds select new Investments { Company = f.company, FullName = f.fullname, Admin = f.admin, Fund = f.fund1, FundCode = f.fundcode, Source = STR_FUNDS, IsPortfolio = false, IsActive = f.active, Strategy = f.strategy, SubStrategy = f.substrategy, AltStrategy = f.altstrategy, AltSubStrategy = f.altsubstrategy, Region = f.region, AltRegion = f.altregion, UseAlternate = f.usealt, ClassesAllowed = f.classallowed }; var stocksInv = from s in db.stocks where !fundInv.Select(f => f.Company).Contains(s.vehcode) select new Investments { Company = s.company, FullName = s.issuer, Admin = STR_PRS, Fund = s.shortname, FundCode = s.vehcode, Source = STR_STOCK, IsPortfolio = false, IsActive = (s.inactive == null), Strategy = s.style, SubStrategy = s.substyle, AltStrategy = s.altstyle, AltSubStrategy = s.altsubsty, Region = s.geography, AltRegion = s.altgeo, UseAlternate = s.usealt, ClassesAllowed = STR_GENERIC }; var bondsInv = from oi in db.bonds where !fundInv.Select(f => f.Company).Contains(oi.vehcode) select new Investments { Company = string.Empty, FullName = oi.issue, Admin = STR_PRS1, Fund = oi.issue, FundCode = oi.vehcode, Source = STR_BONDS, IsPortfolio = false, IsActive = oi.closed, Strategy = STR_OTH, SubStrategy = STR_OTH, AltStrategy = STR_OTH, AltSubStrategy = STR_OTH, Region = STR_OTH, AltRegion = STR_OTH, UseAlternate = false, ClassesAllowed = STR_GENERIC }; return (fundInv.Concat(stocksInv).Concat(bondsInv)).ToList(); } The code above results in a complex select statement where each "table" above has different column count.

  • jquery.ui sortable using a table and item:tr , placeholder difficulties

    - by greg
    Hi I would really like to give some sortable goodness to the myriad old tables I have created. A little work has a proof of concept behaving ok. My one sticking point is that the placeholder does not work at all in IE 7 when using item:TR . It works OK in FF. I can make an perform correctly. It seems to be specific to tables and Any ideas, I have been running through forums, not seeing a lot of people using sortable with tables. <style type="text/css"> .dndPlaceHolder { background-color:Red ; color:Red; height: 20px; line-height:30px; border: solid 2px black; } .dndItem { background-color: #c0c0c0; border:solid 1px black; padding:5px; } </style> <script type="text/javascript" > $(function() { $("#myTable").sortable( { placeholder:'dndPlaceHolder', distance:15, items:'tr', forcePlaceholderSize:true, change : dndChange, update : dndUpdate } ); $("#myTable").disableSelection(); $("#myList").sortable( { placeholder:'dndPlaceHolder', distance:15, items:'li', forcePlaceholderSize:true, change : dndChange, update : dndUpdate } ); $("#myList").disableSelection(); }); function dndChange(event,ui){ } function dndUpdate(event,ui){ var msg = ''; } </script> <table id='myTable' > <tr class='dndItem' id='1'> <td>0 Active - Active</td> </tr> <tr class='dndItem' id='2'> <td>1 Closed - Closed</td> </tr> <tr class='dndItem' id='3'> <td>2 OnHold - On Hold</td> </tr> <tr class='dndItem' id='4'> <td>3 Pending - Pending</td> </tr> </table> <BR> <UL id='myList' > <li class='dndItem' id='1'>0 Active - Active</li> <li class='dndItem' id='2'>1 Closed - Closed</li> <li class='dndItem' id='3'>2 OnHold - On Hold</li> <li class='dndItem' id='4'>3 Pending - Pending</li> </ul>

  • CSS sliding doors technique for buttons, IE8 problem

    - by Kelvin
    Hello All! I used sliding doors technique, explained here: http://www.oscaralexander.com/tutorials/how-to-make-sexy-buttons-with-css.html With only one exception, that I decided to add one more image for "hover" effect. My code works well for all browsers, except IE8 (and maybe earlier versions). a.submit-button:active and a.submit-button:active span are simply blocked by "hover" and never work. Does anyone knows solution for this? Thanks a lot in advance! <style type="text/css"> .clear { /* generic container (i.e. div) for floating buttons */ overflow: hidden; width: 100%; } a.submit-button { background: transparent url('images/button-1b.png') no-repeat scroll top right; color: #fff; display: block; float: left; font: bold 13px sans-serif, arial; height: 28px; margin-right: 6px; padding-right: 18px; /* sliding doors padding */ text-decoration: none; outline: none; } a.submit-button span { background: transparent url('images/button-1a.png') no-repeat; display: block; line-height: 14px; padding: 6px 0 8px 24px; } a.submit-button:hover { background-position: right -28px; outline: none; /* hide dotted outline in Firefox */ color: #fff; } a.submit-button:hover span { background-position: 0px -28px; } a.submit-button:active { background-position: right -56px; color: #e5e5e5; outline: none; } a.submit-button:active span { background-position: 0px -56px; padding: 7px 0 7px 24px; /* push text down 1px */ } </style> And this is the button: <div class="clear"> <a class="submit-button" href="#" onclick="this.blur();"><span>Hello All</span></a> </div>

  • Flash - Ease out scrolling moviclip, scrolled by sensor on each side

    - by webfac
    I am hoping someone can shed some light on this issue for me... I have a movieclip that is scrolled by means of a 'sensor' on each side of the stage. The clip scrolls fine in both directions, however here is my problem: When the users mouse leaves the stage, the movie clip stops dead in it's tracks, and this does not provide a noce smooth effect. Looking at the code below, is there any way I could tell the animation to ease out when the users mouse leaves the stage rather than simply stop suddenly? Much appreciated! class Sensor extends MovieClip { public function Sensor() { } public function onEnterFrame() { // var active:Boolean; // is mouse within sensor? if ((_level2._xmouse >= this._x) && _level2._xmouse <= (this._x + this._width)) { active = true; } else { active = false; } if(active) { // which area of the sensor is it in? var relative_position:Number; var relative_difference:Number; relative_position = _level2._xmouse / this._width * 100.0; //_level2._logger.message("relative position is " + relative_position); if (!isNaN(relative_position)) { // depending on which area it is in, tend towards a particular adjustment if(relative_position > _level2._background_right_threshold) { relative_difference = Math.abs(relative_position - _level2._background_right_threshold); //relative_difference = 10; } else if(relative_position < _level2._background_left_threshold) { relative_difference = Math.abs(_level2._background_left_threshold - relative_position); relative_difference *= -1; } else { _level2._background_ideal_adjustment = 0; } var direction:Number; if(_level2._pan_direction == "left") { direction = 1; } else { direction = -1; } _level2._background_ideal_adjustment = direction * (relative_difference / 10) * _level2._pan_augmentation; //_level2._logger.message("ideal adjustment is " + _level2._background_ideal_adjustment); if (!isNaN(_level2._background_ideal_adjustment)) { // what is the difference between the ideal adjustment and the current adjustment? // add a portion of the difference to the adjustment: // this has the effect that the adjustment "tends towards" the ideal var difference:Number; difference = _level2._background_ideal_adjustment - _level2._background_adjustment; _level2._background_adjustment += (difference / _level2._background_tension); // calculate what the new background _x position would be var background_x:Number; var projected_x:Number; background_x = _level2["_background"]._x; projected_x = background_x += _level2._background_adjustment; //_level2._logger.message("projected _x is " + projected_x); // if the _x position is valid, change it if(projected_x > 0) projected_x = 0; if(projected_x < -(_level2["_background"]._width - Stage.width)) projected_x = -(_level2["_background"]._width - Stage.width); _level2["_background"]._x = projected_x; // i recommend that you move your other movieclips with code here } } } } }

  • Rails ActiveResource Associations

    - by brad
    I have some ARes models (see below) that I'm trying to use associations with (which seems to be wholly undocumented and maybe not possible but I thought I'd give it a try) So on my service side, my ActiveRecord object will render something like render :xml => @group.to_xml(:include => :customers) (see generated xml below) The models Group and Customers are HABTM On my ARes side, I'm hoping that it can see the <customers> xml attribute and automatically populate the .customers attribute of that Group object , but the has_many etc methods aren't supported (at least as far as I can tell) So I'm wondering how ARes does it's reflection on the XML to set the attributes of an object. In AR for instance I could create a def customers=(customer_array) and set it myself, but this doesn't seem to work in ARes. One suggestion I found for an "association" is the just have a method def customers Customer.find(:all, :conditions => {:group_id => self.id}) end But this has the disadvantage that it makes a second service call to look up those customers... not cool I'd like my ActiveResource model to see that the customers attribute in the XML and automatically populate my model. Anyone have any experience with this?? # My Services class Customer < ActiveRecord::Base has_and_belongs_to_many :groups end class Group < ActiveRecord::Base has_and_belongs_to_many :customer end # My ActiveResource accessors class Customer < ActiveResource::Base; end class Group < ActiveResource::Base; end # XML from /groups/:id?customers=true <group> <domain>some.domain.com</domain> <id type="integer">266</id> <name>Some Name</name> <customers type="array"> <customer> <active type="boolean">true</active> <id type="integer">1</id> <name>Some Name</name> </customer> <customer> <active type="boolean" nil="true"></active> <id type="integer">306</id> <name>Some Other Name</name> </customer> </customers> </group>

But when i try to disable view and open perspective, that contains that view (myproject.view.input), it opened without that view, but also throws exception: !STACK 1 org.eclipse.ui.PartInitException: Could not create view: myproject.view.input at org.eclipse.ui.internal.ViewFactory.createView(ViewFactory.java:158) I can show full stacktrace if anyone want. I tried to debug my application and before i open my perspective whith that view, i checked currentState of my CommandState source provider, and all seemes to be ok: all variables values are correct and myproject.view.input.active = DISABLED Can anyone say, why exception is thrown? Thanks for any help. Sorry for big post and bad language

  • sharepoint full text query with attributes missing isn't returning the results I expected

    - by Jason Hocker
    If I am doing a search in sharepoint, some of the results I'm expecting are not being returned. I believe its because in active directory these entries may not have all the fields. So a name that doesn't have the givenName attribute set in active directory is not being returned from this query. Is there a way I can get this to work like I expected? "select LastName, FirstName, PreferredName, AccountName from scope() where \"scope\"='People' AND (LastName like '%" + search + "%' OR FirstName like '%" + search + "%' OR PreferredName like '%" + search + "%')";

  • In Rails, how should I implement a Status field for a Tasks app - integer or enum?

    - by Doug
    For a Rails 3.0 Todo app, I have a Tasks model with a Status field. What's the best way to store the Status field data (field type) and still display a human-readable version in a view (HTML table)? Status can be: 0 = Normal 1 = Active 2 = Completed Right now I have this: Rails Schema Here: create_table "tasks", :force = true do |t| t.integer "status", :limit = 1, :default = 0, :null = false Rails Model Here: class Task < ActiveRecord::Base validates_inclusion_of :status, :in => 0..2, :message => "{{value}} must be 0, 1, or 2" Rails View Here: <h1>Listing tasks</h1> <table> <tr> <th>Status</th> <th>Name</th> <th></th> <th></th> <th></th> </tr> <% @tasks.each do |task| %> <tr> <td><%= task.status %></td> <td><%= task.name %></td> <td><%= link_to 'Show', task %></td> <td><%= link_to 'Edit', edit_task_path(task) %></td> <td><%= link_to 'Delete', task, :confirm => 'Are you sure?', :method => :delete %></td> </tr> <% end %> </table> Requirements Store a Task's status in the db such that the values are easily localizable, i.e. I'm not sure I want to store "normal", "active", "completed" as a string field. Solution must work with Rails 3.0. Questions: Should I store the field as an integer (see above)? If so, how do I display the correct human readable status in an HTML table in my Rails view, e.g. show "Active" instead of "1" in the HTML table. Should I use an enum? If so, is this easy to localize later? Should I use straight strings, e.g. "Normal", "Active", "Completed" Can you provide a quick code sample of the view helper, controller or view code to make this work?

  • Google Maps iPhone API Terrain View

    - by Adam
    We're using MapKit on an iPhone app to display a Google Map with terrain view. However, the terrain view only shows when the user has an active Internet connection, the moment the user's Internet is off, the terrain on the map disappears and it appears flat. Is there any way to keep the terrain view on even when the user isn't on an active internet connection? Thanks! Adam

  • \center environment centers the whole document in LaTeX

    - by Seamus
    I have the following line between my \maketitle and my \begin{abstract}: \center{ \textsc{Some text here} } This seems to cause the ENTIRE DOCUMENT to be formatted as centered. Why is this and how should I get around it? Part two: Is there a way to get some text to appear only when the [draft] option is active. For example, when the draft option is active, I want some text to appear between my title and abstract: "draft: do not cite without permission" or some such.
