  • Windows Server 2008 - RAID 5 Fails on Reboot

    - by Adam
    Hey, I've got an install of Windows Server 2008 Enterprise. It's running software RAID-5 with five disks. The disks were originally formatted under Windows Server 2003, but came up fine once I installed Windows Server 2008. The issue I'm having is that every time I reboot the server, the RAID comes up with a "Failed Redundancy" - the data stays available. I have 4 disks on a PCI SATA controller, and one of the disks connected to the motherboard's on-board SATA ports. (The other on-board port has the system disk connected.) I was having Disk #4 fail consistently, so I tried swapping the cables on the controller end. I swapped the on-board RAID disk with one on the PCI controller. Same issue now, expect with disk #1. Once the system's up, I can reactivate the RAID, it will resync for a while, then go to "Healthy", and will stay that way for an indefinite amount of time - until I reboot. As soon as I reboot, the disk drops again. I've ruled out disk + cable with the recabling. I don't believe it would be the controller as it seems to work fine most of the time - only failing on reboot, and the other port on the same controller connects the system disk - which is clearly working. I did look in the event log, but didn't see anything particularly relevant (although I didn't know what I was looking for - just looked for anything with a "Warning" or "Error" symbol that looked disk-related :)). I'm not particularly familiar with RAID on Windows, does anyone have any idea why this might be doing this? Any idea how to fix it? Any suggestions appreciated! -- Adam

  • piping in UNIX doubt

    - by Happy Mittal
    In The Unix Programming Environment by K & P, it is written that " The programs in a pipeline actually run at the same time, not one after another. This means that programs in a pipeline can be interactive;" How can programs run at same time? For ex: $ who | grep mary | wc -l How grep mary will be executed until who is run or how wc -l will be executed until it knows results of previous programs?

  • Commercial Java LIB / API to read and write Word 2007 docs

    - by AlfaTeK
    I need a simple to use / good docs / good support java lib to read and write word documents, namely word 2007 support (and word 2010 support planned). As the project I'm in has budget and time-constraints I don't mind buying a commercial lib :) I know they are XML files in a somewhat open format but I really don't want to waste time understanding the XML specification. Any good recommendations from happy customers? (Right now my choice is going to Aspose.Words for Java)

  • Check for unique rows, but ignore one particular column

    - by user269148
    I have an XML document, that looks like this: Column A to S with headers, and there are 1922 rows. This is an backup of some SMS, and I want to get rid of duplicates. The problem is, that the Time in the readable_date header has been messed up. There is nothing wrong with the date, but the clock time is wrong, so I have split that column in three, with Year, day and clock. I know I can use a standard filter, but it only looks for unique rows in a single column. What I want to perform, is to make a row check similar to this: F(x)=Check if Column 2A to (infinate) is equal to Column 3A to (infinate), but ignore column(R). IF True, then delete Column 3A to (infinate) Otherwise Check IF column 2A to (infinate) is equal Column 4A to (infinate) and so on. I need to ignore a particular column in a row every time, and need to do this for a complete sheet. And the formula check should apply for every row, when the first one is done checking for duplicates... If anyone else has a better solution, please say so. Anyway, anyone who can help?

  • Windows Small Business System 2003. SQL timeout in Server Performance Report

    - by tetranz
    I'm the volunteer IT admin at a small school. We have SBS 2003 with about ten desktops. The server performance report is emailed to me daily. It is setup with a wizard in the Monitoring and Performance part of the "Server Management" console. It often fails with a "The page cannot be displayed" error. The event log shows Event Type: Error Event Source: ServerStatusReports Event Category: None Event ID: 1 Date: 1/16/2011 Time: 6:03:14 AM User: N/A Computer: ALPHA Description: Server Status Report: URL: http://localhost/monitoring/perf.aspx?reportMode=1&allHours=1 Error Message: Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding. Stack Trace: at System.Data.SqlClient.SqlConnection.OnError(SqlException exception, TdsParserState state) at System.Data.SqlClient.SqlInternalConnection.OnError(SqlException exception, TdsParserState state) at System.Data.SqlClient.TdsParser.ThrowExceptionAndWarning() at System.Data.SqlClient.TdsParser.ReadNetlib(Int32 bytesExpected) [plus lots more stack trace] This has been happening for years :) I've never really solved it. It seems to be related to WSUS. When it happens, I run the Update Services "Server Cleanup Wizard". That takes a long time to run. If I haven't run it for a while it can take 10 hours. I also run the WsusDBMaintenance.sql script (from TechNet I think) which reindexes the database etc. Those two things seem to get it working again for a while. Recently the "while" has become a couple of weeks. My searching online has revealed lots of people having this problem but no real solution. Does anyone have any good ideas about this? I have to wonder if something in the WSUS SQL schema is not indexed properly. The time that the server cleanup wizard takes seems ridiculous. Thanks

  • How to see the properties of a DOM element as they change in realtime?

    - by allquixotic
    JavaScript code can update the properties/attributes of DOM elements in real time by responding to events and so on. Here is an example. In the table on that page, move your mouse over the cells. Notice how they change color when the mouse is on them, and the color goes away when you move the mouse to another cell. Now, using Firefox or Chrome (but not IE, Opera, etc.), I want to examine the background color, expressed in RGB or hex or whatever, of the cells updated in real time, as the mouse cursor enters and leaves the region and causes the JS to do its thing. The behavior that I observe, currently, is that the Inspect Element functionality of both Firefox and Chrome does not update the value of the properties as they are updated by JavaScript. So, in order to view the latest value of the property, I have to inspect the element again, and it takes a momentary "snapshot" of the values. But since the values only change while I have the mouse on them, I can't take a snapshot of the value I want while my mouse cursor is over the cell, because I have to remove my mouse from the cell to select the "Inspect Element" item in the right-click list! If it is possible to have the values updated in real time using either Firefox or Chrome, or an extension, on any recent version of the software (up to the latest stable), please provide instructions for doing so.

  • Autounmounting USB keys with FAT filesystem on Linux (RHEL5)

    - by niXar
    For security reasons, I have two workstations i front of me, and I can only transfer data between them through a USB key. As you can imagine, it can get quickly tiresome, but the most annoying is having to unmount the things before removing them. Not umounting them results in missing files most of the time, even if I remove them a while after having last written to them. Now, since they're only used for transferring smallish files, and each are basically written once and read once, I don't need the fancy pansy caching infrastructure that makes clean unmounting a necessary step. And since the data is always a copy of something I have at hand, I don't care if the filesystem croaks from time to time. But anyway the system doesn't need to force that on me, it could simply make sure everything is committed with a second, and works synchronously. Then when I remove the key, nothing is lost. Is there a way to do this? I would appreciate any other tips on handling this situation. Edit: it appears the situation has changed between RHEL5 and Fedora up to F11 on one hand, and F12 on the other. The latter use DeviceKit-disk, and I haven't quite figured out how to do this. The method provided below in gconf does not work anymore.

  • Best way to keep a large number of hobby projects alive; open sourcing?

    - by Daan van Yperen
    Because my time is limited I can usually only focus on one or two of my hobby projects, while the others sit there wasting away. I am looking for a solution that would allow me to divide my time better. is open sourcing where I take the role of guiding the project realistic, or are there better solutions? In my case, one project has a reasonably sized community of users going for it but is currently closed source. There have been requests to open source it.

  • jQuery attribute auto added to elements

    - by macca1
    After using the IE8 built in Developers Tools for the first time, I noticed jQuery is attaching an attribute to some of my elements: I've never noticed this before. In fact, this doesn't show up in Firebug... I'm only seeing it for the first time now in IE8 Developer Tools. Does anyone know what jQuery uses this for, and why it's hidden in firebug?

  • May we have Ruby and Rails performance statistics? We're persuading the business to use Rails!

    - by thekingoftruth
    We're convincing our Products officer that we want to use JRuby on Rails, and we're having a hard time coming up with some statistics which show that: Coding time is less using Rails vs. say Struts or Zend Framework or what have you. Ruby (and JRuby in particular) performance isn't horrible (anymore). Rails performance isn't bad either. If you can get us some good stats quickly, we might have a chance!

  • Java Data Structure

    - by Joe
    Hi there, I'm looking for a data structure that will act like a Queue so that I can hava First In First Out behaviour, but ideally I would also be able to see if an element exists in that Queue in constant time as you can do with a HashMap, rather than the linear time that you get with a LinkedList. I thought a LinkedHashMap might do the job, but although I could make an iterator and just take and then remove the first element of the iteration to produce a sort of poll() method, I'm wondering if there is a better way. Many thanks in advance

  • ReadFile doesn't work asynchronously on Win7 and Win2k8

    - by f0b0s
    According to MSDN ReadFile can read data 2 different ways: synchronously and asynchronously. I need the second one. The folowing code demonstrates usage with OVERLAPPED struct: #include <windows.h> #include <stdio.h> #include <time.h> void Read() { HANDLE hFile = CreateFileA("c:\\1.avi", GENERIC_READ, 0, NULL, OPEN_EXISTING, FILE_FLAG_OVERLAPPED, NULL); if ( hFile == INVALID_HANDLE_VALUE ) { printf("Failed to open the file\n"); return; } int dataSize = 256 * 1024 * 1024; char* data = (char*)malloc(dataSize); memset(data, 0xFF, dataSize); OVERLAPPED overlapped; memset(&overlapped, 0, sizeof(overlapped)); printf("reading: %d\n", time(NULL)); BOOL result = ReadFile(hFile, data, dataSize, NULL, &overlapped); printf("sent: %d\n", time(NULL)); DWORD bytesRead; result = GetOverlappedResult(hFile, &overlapped, &bytesRead, TRUE); // wait until completion - returns immediately printf("done: %d\n", time(NULL)); CloseHandle(hFile); } int main() { Read(); } On Windows XP output is: reading: 1296651896 sent: 1296651896 done: 1296651899 It means that ReadFile didn't block and returned imediatly at the same second, whereas reading process continued for 3 seconds. It is normal async reading. But on windows 7 and windows 2008 I get following results: reading: 1296661205 sent: 1296661209 done: 1296661209. It is a behavior of sync reading. MSDN says that async ReadFile sometimes can behave as sync (when the file is compressed or encrypted for example). But the return value in this situation should be TRUE and GetLastError() == NO_ERROR. On Windows 7 I get FALSE and GetLastError() == ERROR_IO_PENDING. So WinApi tells me that it is an async call, but when I look at the test I see that it is not! I'm not the only one who found this "bug": read the comment on ReadFile MSDN page. So what's the solution? Does anybody know? It is been 14 months after Denis found this strange behavior.

  • Building My First Computer And Suprise It Isn't Working

    - by BobbShots
    I've had many years of experience working on and around computers, but this was my first foray into building one completely from scratch. So far that foray has been a disaster. My rig is completely assembled, and on its maiden power-up plus many power cycles I noticed three things: There were a few beeps from the BIOS POST upon powering up the first time, but I wasn't paying attention completely to the sequence. However, every time after that there are 0 POST beeps, even after taking off all hardware except the CPU and MB. There was no video being sent to the monitor. I run a HDMI cable from my video card to the monitor. The video card was LOUD. My card is a Sapphire Radeon HD 5870 which is known for not only being a powerhouse, but being pretty quiet. A few times during my power cycles it ran a lot quieter, but most of the time it was just super loud. Can anyone provide help for any of these issues? My MB, CPU, and Video Card are: MB: ASUS P6X58D Premium LGA 1366 Intel X58 SATA 6Gb/s USB 3.0 ATX Intel Motherboard CPU: i7 920 Video Card: Sapphire Radeon HD 5870

  • Windows VPN always disconnects after < 3 minutes, only from my network

    - by hemp
    First, this problem has existed for almost two years. Until serverfault was born, I pretty much gave up on solving it - but now, hope is reborn! I've set up a Windows 2003 server as a domain controller and VPN server at a remote office. I am able to connect to and work over the VPN from every windows client I've tried, including XP, Vista, and Windows 7 without issue, from at least five different networks (corporate and home, domain and non.) It works fine from all of them. However, whenever I connect from clients on my home network, the connection drops (silently) after 3 minutes or less. After a short while, it will eventually tell me the connection has dropped and attempt to redial/reconnect (if I've configured the client that way.) If I reconnect, the connection will re-establish and appear to work correctly, but again will silently drop, this time after a seemingly shorter time period. These are not intermittent drops. It happens every single time, in exactly the same way. The only variable is how long the connection survives. It doesn't matter what type of traffic I send. I can sit idle, send continuous pings, RDP, transfer files, all of that at once - it makes no difference. The result is always the same. Connected for a few minutes, then silent death. Since I doubt anyone has experienced this exact situation, what steps can I take to troubleshoot my evanescing VPN?

  • Silverlight DataGrid Exception Reordering Column Headers

    I'm trying to set the initial display order of the column headers in a silverlight datagrid by changing the column header DisplayIndex values. If I try to set the column order at page load time, I get an out of range exception. If I set the column order (same routine) at a later time like, in a button click handler, it works. Is this just a bug in the silverlight datagrid control? Suggestions for a possible work around?
