  • Server refuses to boot when Raid5 disk is disconnected - /root/ missing

    - by Ronni
    I recently set up a NAS server running a Debian OS (6.0.4) It contains 4 disks, 3 of them are in a Raid5 array, while the last one is used for the OS. To simulate a disk-failure I unplugged one of the raid disks, which resulted in the OS being unable to boot. It started the boot, recognized that md0 (the raid array) was running on 2/3 disks, and then threw a few errors. It was unable to find the following directories: /dev/root on /root, /dev on /root/dev, /sys on /root/sys, /proc on /root/proc It appears this happens regardless of which raid disk is removed. These directories are supposed to be on /dev/sdd my system disk. Output from fstab and blkid : http://dl.dropbox.com/u/6017799/NASOutput.txt If you need additional info, please let me know.

  • Getting Started With SEO on Your New Website

    I have learned that the best thing a brand new website can do is get one way links to their site. So for someone who is brand new at this that should be job #1.

  • LinkedIn API returns 'Unauthorized' response (PHP OAuth)

    - by Jim Greenleaf
    I've been struggling with this one for a few days now. I've got a test app set up to connect to LinkedIn via OAuth. I want to be able to update a user's status, but at the moment I'm unable to interact with LinkedIn's API at all. I am able to successfully get a requestToken, then an accessToken, but when I issue a request to the API, I see an 'unauthorized' error that looks something like this: object(OAuthException)#2 (8) { ["message:protected"]=> string(73) "Invalid auth/bad request (got a 401, expected HTTP/1.1 20X or a redirect)" ["string:private"]=> string(0) "" ["code:protected"]=> int(401) ["file:protected"]=> string(47) "/home/pmfeorg/public_html/dev/test/linkedin.php" ["line:protected"]=> int(48) ["trace:private"]=> array(1) { [0]=> array(6) { ["file"]=> string(47) "/home/pmfeorg/public_html/dev/test/linkedin.php" ["line"]=> int(48) ["function"]=> string(5) "fetch" ["class"]=> string(5) "OAuth" ["type"]=> string(2) "->" ["args"]=> array(2) { [0]=> string(35) "http://api.linkedin.com/v1/people/~" [1]=> string(3) "GET" } } } ["lastResponse"]=> string(358) " 401 1276375790558 0000 [unauthorized].

If anyone could offer some advice or point me in the right direction, I will be extremely appreciative!

  • Small performance test on a web service

    - by vtortola
    Hi, I'm trying to develop a small application that test how many requests per second can my service support but I think I'm doing something wrong. The service is in an early development stage, but I'd like to have this test handy in order to check in time to time I'm not doing something that decrease the performance. The problem is that I cannot get the web server or the database server go to the 100% of CPU. I'm using three different computers, in one is the web server (WinSrv Standard 2008 x64 IIS7), in other the database (Win 2K - SQL Server 2005) and the last is my computer (Win7 x64 ultimate), where I'll run the test. The computers are connected through a 100 ethernet switch. The request POST is 9 bytes and the response will be 842 bytes. The test launches several threads, and each thread has a "while" loop, in each loop it creates a WebRequest object, performs a call, increment a common counter and waits between 1 and 5 millisencods, then it do it again: static Int32 counter = 0; static void Main(string[] args) { ServicePointManager.DefaultConnectionLimit = 250; Console.WriteLine("Ready. Press any key..."); Console.ReadKey(); Console.WriteLine("Running..."); String localhost = "localhost"; String linuxmono = "192.168.1.74"; String server= "192.168.1.5:8080"; DateTime start = DateTime.Now; Random r = new Random(DateTime.Now.Millisecond); for (int i = 0; i < 50; i++) { new Thread(new ParameterizedThreadStart(Test)).Start(server); Thread.Sleep(r.Next(1, 3)); } Thread.Sleep(2000); while (true) { Console.WriteLine("Request per second :" + counter/DateTime.Now.Subtract(start).TotalSeconds ); Thread.Sleep(3000); } } public static void Test(Object ip) { Guid guid = Guid.NewGuid(); Random r = new Random(DateTime.Now.Millisecond); while (true) { String test = "<lalala/>"; WebRequest req = WebRequest.Create("http://" + (String)ip + "/WebApp/"+guid.ToString()+"/Data/Tables=whatever"); req.Method = "POST"; req.ContentType = "application/xml"; req.Credentials = new NetworkCredential("aaa", "aaa","domain"); Byte[] array = Encoding.UTF8.GetBytes(test); req.ContentLength = array.Length; using (Stream reqStream = req.GetRequestStream()) { reqStream.Write(array, 0, array.Length); reqStream.Close(); } using (Stream responseStream = req.GetResponse().GetResponseStream()) { String response = new StreamReader(responseStream).ReadToEnd(); if (response.Length != 842) Console.Write(" EEEE "); } Interlocked.Increment(ref counter); Thread.Sleep(r.Next(1,5)); } } If I run the test neither of the computers do an excesive CPU usage. Let's say I get a X requests per second, if I run the console application two times at the same moment, I get X/2 request per second in each one... but still the web server is on 30% of CPU, the database server on 25%... I've tried to remove the thread.sleep in the loop, but it doesn't make a big difference. I'd like to put the machines to the maximun, to check how may requests per second they can provide. I guessed that I could do it in this way... but apparently I'm missing something here... What is the problem? Kind regards.
