• pgpool2+streaming replication failover on only 2 servers?

  - by aneez

  I am trying to configure pgpool2 and postgresql 9.1 to handle failover. I currently have streaming replication running, and are using pgpool2 for read-only load balancing. I have 2 servers in my setup, both running postgresql - 1 master and 1 slave. The master is also running pgpool2. My question is how do I configure this setup to handle failover? Specifically in the case that the master crashes, and the slave has to take over and run pgpool2 as well. Most documentation and examples I have been able to find assumes that pgpool2 is running on a separate server and thus "never" crashes. I may or may not be attacking the problem using the wrong tools. In my production setup I have a total of 3 identical servers all in independent locations. The main goal of the setup is to achieve a high uptime. Thus failover should be automatic, and bringing a failed node back up should cause only minimal downtime. I want all 3 nodes to be as close to identical as possible, and be able to run with just 1 or 2 nodes available. And if possible I want to use load balancing to improve performance. If anyone can help me gain some insight into how to do this using my current setup or suggest a different/better setup. Thank you!

• MySQL server hangs after approximately 1 month (CentOS)

  - by user25061

  Hey guys, I've got a web server running Apache/PHP and MySQL (CentOS), and MySQL seems to hang once every month or so. As far as I can tell, there are a few slow queries that are being resolved, but other than that I can't really see any reason why MySQL would hang. I'm having problems determining the problem - nothing is showing up in /var/log/mysqld.log, and again there are a few slow queries, but nothing out of the ordinary. Load is average at the time of the crashes... Can I please get some hints on how to work out the issue? I can't reproduce on our staging environment, so I'm a little stuck.

• Database implementation question?

  - by gundam

  consider a disk with a sector size of 512 bytes, 2000 tracks/surface, 50 sectors/track, 5 doubled sided platters, average seek time is 10 msec. Assume a block size of 1024-byte is selected. Assume a file that contains 100,000 records of 100-byte each is to be stored on the disk, and NONE of the reocd can be spanned 2 blocks. How many blocks are needed to store the entire file?? If the file is arranged sequentially on disk, how many surfaces are required?? Now, i have calculated that 10,000 blocks are needed to store 100,000 records. But i am not sure how to find out the answer of the surfaces required. I only calculated the capacity of track is 25KB and capacity of surface is 50,000 KB But I don't know how to calculate the number of surfaces... Could anyone help me how to get the answer? Thanks a lot!!

• VirtualBox: Ubuntu installed in Windows 7 OR Windows 7 installed in Ubuntu

  - by user584968

  The title of the post sums up my questions: Is performance better, on average, assuming Ubuntu and Windows are used equally and for the same purposes, when Ubuntu is installed inside of Windows 7 or when Windows 7 is installed inside of Ubuntu using VirtualBox? My gut instinct tells me that because Ubuntu drivers are mostly open source, optimizations could be made when translating the virtual system calls of Ubuntu through Windows 7 that could not be made if it were flipped the other way around, because of the closed nature of Windows drivers. However, this is just a guess, and I have no evidence to back this up. I'm not sure, so I thought it would be best if I opened up this question to the experts of the community. I look forward to reading your responses!

• Why am I getting a Sharepoint error on a simple "hello world" web page?

  - by Fetchez la vache

  I've been granted admin access to an internal IIS server on which I need to set up a web site. Before doing anything technical I wanted to ensure that I could access the server, but when attempting to access a simple page (that does not refer to Sharepoint) at http://localhost/index.html when logged onto the server directly, I am getting Parser Error Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately. Parser Error Message: Could not load file or assembly 'Microsoft.SharePoint' or one of its dependencies. The system cannot find the file specified. Source Error: Line 1: <%@ Assembly Name="Microsoft.SharePoint"%><%@ Application Language="C#" Inherits="Microsoft.SharePoint.ApplicationRuntime.SPHttpApplication" %> Source File: /global.asax Line: 1 Assembly Load Trace: The following information can be helpful to determine why the assembly 'Microsoft.SharePoint' could not be loaded. WRN: Assembly binding logging is turned OFF. To enable assembly bind failure logging, set the registry value [HKLM\Software\Microsoft\Fusion!EnableLog] (DWORD) to 1. Note: There is some performance penalty associated with assembly bind failure logging.

Cheers :) Update: I've since supposedly uninstalled Sharepoint, but am still getting this error. Any ideas welcome!

• Windows XP VM on VMWare ESXi 4.1 "pausing" / blocked occasionally

  - by FelixD

  We have an issue with Windows XP SP3 VMs on VMWare ESXi 4.1.0 (the free version): They sometimes seem to "pause" for several minutes. This happens rarely (maybe once a month per VM, at least noticed only that often), but still is an issue for us. It happens for three different but similar VMs on three pretty different hosts (different hardware). I have the feeling that the "pausing" is not actually the CPU blocking, but probably the harddisks, but not 100% sure. The servers have one IDE disk (C:) and one SCSI (D:) and it might be either of the two. I have seen scheduled tasks simply not starting for up to 9 minutes and then running normally again with normal speed. They were totally blocked. This is not a load issue, the VMWare hosts have average load and the VMs in question already have reserved CPU resources plus high priorities for CPU and disk. The Windows boxes run mainly MySQL, Tomcat, FileZilla server, Cygwin stuff, Java + R applications, VMWare client, Elusiva Terminal Server pro, Nagios client. Not sure if this might be related with any of that software (e.g. Elusiva). Trying to debug this, there was nothing visible in Windows Event log, other logs in C:\Windows, VMWare events etc. Unfortunately the vmware.log file ends with "Log throttled". We found that we ran into 2 VMWare bugs there: The VMWare client writes lots on bogus messages in the vmware.log, which we now disabled (log level error setting) plus the bug that VMWare does not unthrottle the log (at least so far despite VM reboots). I know there is not much guidance and that may also be the reason why I so far didn't find anything related on the web or on ServerFault, but maybe some of this rings a bell with someone? Or please direct me to what more info to post. I hope that the vmware.logs get unthrottled eventually (can't easily restart the hosts at the moment). Thanks for any input!

• System Issues and Major Malfuctions after Failed hibernation Exit

  - by Sarah Seguin

  I have a HP G71-340US that went into hibernation mode for a while and when I tried coming out of it, I got an error message: You're computer cannot come out if hibernation . Status: 0xc000009a Info: A fatal error occurred processing the restoration data. File: \hiberfil.sys Any information that was not saved before the computer went into hybernation will be lost enter=continue So I hit continue and it ran soooo super slow it. It was seriously crawling. Finally I gave up and turned it off manually (IE press and hold the button). It's been a week or two since then and EVERY SINGLE TIME I have tried to to do ANYTHING it takes forever. When I say forever, I literally mean takes 5-7 minutes to load the internet, then the page itself, then to click a link, so on so forth. Eventually everything just goes not responding and I have to give up (4-6 HOURS later). I also cannot access my thumb/jump drives once I've managed to load windows. I was going to try runing malware bytes incase of a virus, but it's windows explorer developes errors and goes not responding on me. Currently I'm running scan disk or check disk and like every file is coming back unreadable. I let it run the last 2 hours straight in chkdesk and I'm only at 6 percent with around 500+ errors and still going. Yes, I've taken logs of the errors via cell phone camera and patience. A week or two prior to this happening I had to change our the hard drive due to blunt force trama next to the mouse. OH! Running on Windows 7: ) And I've tried loading the computer in safe mode and it makes absolutely no difference. Any and all help would be appreciated. I really don't know what to do from here and I'm kind of freaking out. I've googled different part of the error and things that I've done/seen and there are so many different answers/topics that I thought it best to just post the questions.

• wireless printer - entering WPA - is there a quicker way?

  - by camcam

  I have a wireless printer (Brother DCP-585CW). The wireless setup instruction says I should enter the WPA key to the printer. The key is entered using up and down buttons on the printer. So, I am supposed to enter 64 characters using up and down buttons. To enter 1 character, it takes on average (24+10)/2 = 17 times pressing the button (digits start after 24 letters). So 17*64 = 1088 times. Is there a quicker way to setup a wireless printer? Maybe there is a Windows program that discovers printers connected to computer through USB or Ethernet (my printer has both sockets) and allows to pre-configure it for wireless usage (enter the long WPA key)? Update There is BRAdmin program and it allows to set up almost all wireless settings... almost - all except WPA :(

• Server 2003 slow share.

  - by G V

  I am running an 03 box with shares active. When uploading to the share, the speed is average. About 15-20 mbps.. But when you think about it, it is bad because it is a direct connection to a couple machines. When uploading to another server the connection speed is twice that of the direct storage. When uploading s massive folder, 250 GB, the upload will start as normal, but as it progresses it drops in speed. Now it is sitting at around 2-7 Mbps. Any ideas on how i can boost the transfer rate? On a side note, the download speed is great. It is a speed that you would expect from this setup, the main problem is uploading and what is causing the extreme slowness in speeds. Any help would be great.

• IIS Web Farm Framework servers are automatically set to "unavailable" even when they are healthy... And they never return to the available state!

  - by JohannesH

  I have 2 web farm configurations, one with 2 member servers and one with 3 member servers. I have health monitoring set up on both farms and the monitoring tool reports all servers as being healthy. However after a while all the servers are marked as being "Unavailable" and "Healthy" in the "Monitoring and Management" screen (in the "Servers" screen they are all listed with "Yes" in the "Ready for Load Balancing" column). Viewing the event log on both the web farm controller or any of farm servers doesn't reveal anything interesting. there are no warnings or errors in the period where the servers became unavailable. There are a couple of informational events about the worker process getting shut down due to inactivity but I don't hope this is the cause since that would mean that the farms will die during the night when the load is low. Am I missing something? EDIT: Btw, I think its very odd that the application pool shuts down on the servers since the health monitoring system is polling an aspx page on each server. Shouldn't that keep them going? EDIT2: Now I've also experienced this problem with the RTW version of Web Farm Framework 2.

• Merge Two Folders To Act As One (Software Raid 0?)

  - by Dboy1612

  Using Windows 7, I'm trying to setup what I've come to call a "Software Raid of Folders", not completely sure it's the right term, but I'm sure anyone who knows the true term will understand what I'm getting at. I have two folders, on two seperate harddrive, I would like to "merge" these folders while keeping them on seperate harddrive so they act as one folder. Example: Music and Videos are to be merged together to a new folder called "Merged" Music runs off of Harddrive 1 Videos runs off of Harddrive 2 Anything new saved inside Merged is saved within Videos that runs off of Harddrive 2 Now you see how I came up with the term "Software Raid", it's like an average RAID 0 setup, but instead I want to do it with just two specific folders on two different drives within Windows. Any help on this is apprecieated!

• Fedora 16 Running Hot

  - by sdasdadas

  Since switching from Windows 7 to Fedora 16, my laptop has been running incredibly hot (by the air exhaust). The laptop is an Asus K73S. Running 'sensors', I receive: acpitz-virtual-0: 75.0 celsius nouveau-pci-0100: 66.0 celsius asus-isa-0000: 75.0 celsius The only CPU hog is Firefox at 30 - 40% on average. My GPU information (from lspci) is: Intel Corporation Xeon E3-1200/2nd Generation Core Process or Family Integrated Graphics Controller (rev 09). Running lspci | grep -i VGA, returns: 00:02.0 VGA compatible controller: Intel Corporation 2nd Generation Core Processor Family Integrated Graphics Controller (rev 09) 01:00.0 VGA compatible controller: nVidia Corporation GF106 [GeForce GT 555M SDDR3] (rev a1) I don't notice a huge difference running without the battery, but it does seem a little cooler. Thanks!

• Why do SSD drives get so much more expensive as they get larger?

  - by futuraprime

  Normal HDD costs go up very little as drives get larger. For example, an average 1TB drive costs a little under $90, 2TB costs a little over $100, and a 3TB drive costs close to $150. For HDDs, the cost per GB goes down as the number of GB goes up. SSD costs don't work like this: a 128GB SSD goes for $120ish, 256GB goes for $250ish, and 512GB drives get up to $600. The cost per GB goes up as the number of GB rises. What is it about SSDs that makes them so much costlier as they get larger?

• How does everyone set up AWS for PHP with a git workflow while worrying about distributing EC2?

  - by Parris

  Hello, I have been looking for something like heroku but for php, and after much frustration (and almost finding what I need, but not quite) we decided to just go with AWS without any other abstraction. We are using PHP 5.3 (and CakePHP 1.3), and are currently using git. Ubuntu seems like the easiest way to get both of those on there and we will most likely use that. We aren't really going worry about outgoing email. We are using smtp through gmail, but will most likely switch to some other service eventually. I had 3 questions: 1) I have been looking at Zend Server, and I am not quite sure how that is more beneficial than xampp. Perhaps it is not? 2) I suppose to make the application scale we would need multiple instances of some ec2 ami. Then just duplicate it and such. The question then becomes how do we make sure all EC2 instances are up to date? 3) I understand the concept of load balancing to some degree. I understand that in 1 region you select a bunch of servers and have it load balance across them. The question then becomes well how about world wide? How do I make it so that traffic is directed to the correct ec2 server? I have heard of route 53, and tried signing up for that, but nothing appears in my control panel. Also perhaps it is just a DNS thing with my domain registrar? AHHH... some tutorial would be helpful!

• Windows 8: 100% disk active time, no actual data transferred

  - by fingerbangpalateclick

  Occasionally, like several times an hour, my hard drive will appear to lock up: Task Manager will show 100% active time with read and write speeds of 0. I can still switch between open windows, but anything that requires a disk access will stall for around a minute until the hard disk starts working properly again. It happens at apparently random intervals, and only happens in Windows 8. Not 7, nor Linux. It is probably not a problem with the disk itself: This is a relatively new hard drive, and S.M.A.R.T. is showing no errors. Only happens in Windows 8: not any other OS that has used the same partition, or different partitions. So, what is going on? How can I fix this? Note: this is a different problem then this one: Extremely high disk activity without any real usage My task manager would look similar, but Average Response Time, Read Speed, and Write Speed would all be 0.

• Is is better to combine Apache for file manipulation and upload and Nginx for static file serving, or to use one of the two alone

  - by user1032393

  Based on my research, I've read that nginx is best and ideal for serving up static files and images. My application depends heavily on uploading of images and rewriting them, then serving them up. Given that I only have one VPS currently, it has been suggested that I use nginx to serve up the images and website, and reverse proxy to Apache (on the same VPS) to rewrite files with image magick and handle the file uploads. Which would be the best solution, Apache, Nginx, or Apache + Nginx? In terms of best solution, I'm looking at minimal average RAM consumption, while maintaining decent load speed of maybe sub 2 seconds?

• ESXI 4.0 Slow response in opening anything accross the network on a Virtual Server running Win2008

  - by user40944

  Hi I recently installed a HP ML350G6 Server with Windows Small Business Server 200864bit, Exchange 2007. The server was running fantastically and we transferred all user data onto the new server and no problems for 2 weeks! We then installed SQL2008 and transferred the accounts package onto the server and this is where the problems started. Users are now complaining to open a work document can take 2 minutes and the same with regard to anything else. The server itself seems fine, the virtual server seems fine! No disk performance problems (doesn't go above 50% unless i really copy lots of things), no memory, (12Gb only using 7Gb) cpu (usage is low average about 15%) etc on both the VM and in Windows Task manager. I have made sure disk caching is enabled on the raid controller (which made no difference). Network cards are running 1Gb and plugged into HP GB switch. Please help!

• Is it possible to ack nagios alerts from the terminal on a remote workstation?

  - by cat pants

  I have nagios alerts set up to come through jabber with an http link to ack. Is is possible there is a script I can run from a terminal on a remote workstation that takes the hostname as a parameter and acks the alert? ./ack hostname The benefit, while seemingly mundane, is threefold. First, take http load off nagios. Secondly, nagios http pages can take up to 10-20 seconds to load, so I want to save time there. Thirdly, avoiding slower use of mouse + web interface + firefox/other annoyingly slow browser. Ideally, I would like a script bound to a keyboard shortcut that simply acks the most recent alert. Finally, I want to take the inputs from a joystick, buttons and whatnot, and connect one to a big red button bound to the script so I can just ack the most recent nagios alert by hitting the button lol. (It would be rad too if the button had a screen on the enclosure that showed the text of the alert getting acked lol) Make fun of me all you want, but this is actually something that would be useful to me. If I can save five seconds per alert, and I get 200 alerts per day I need to ack, that's saving me 15 minutes a day. And isn't the whole point of the sysadmin to automate what can be automated? Thanks!

• PHP's page generation time takes 0.01s. 1/0.01 = 100; however i'm having problems reaching that number of request per seconds. Why?

  - by cedivad

  On average, my PHP page generation time is 10ms. So i should be able to execute 100 requests one after the other one (using a single core on the server, since that php is not multithreaded). However, i'm having problems reaching 50 pages per seconds. As of now i do 25 on avg., with a medium load. The application is really light, it consist in a read (<5KB) from a pool of SSDs, some read queries solved by indexes. Where should i look to solve this bottleneck?

• Seemingly random disconnections on Windows Server 2008 R2

  - by bobblez

  So I have a box running a Windows Server 2008 R2 in my LAN, which is running, among other things, a voip server used by other people. I myself am in the same subnet with the server, while the other users are not. Now, maybe on average twice a day, all the other users get disconnected from the server (and if I take a remote desktop connection to it, I'm not able to open any web pages either). These disconnections usually last only about 5 seconds, but sometimes they may last up to a minute. What could possibly cause this? I have all the updates installed from windows update and the motherboard of the server is asus p5b deluxe (if that is of any interest). edit: Forgot to mention that my own internet connectivity stays intact while the server's does not, and both computers are behind the same router.

• Notepad++ FTP best solution

  - by yoda

  Hi, I use Notepad++ for more than 2 years now, and there's only 1 thing that it needs for me to be perfect: a actually-working-ftp-plugin. It has an ftp plugin, written by someone that meanwhile left the project (by meanwhile I mean a long time ago), and since then nobody had courage to improve it. The problem is that it does't handle connections very well. Sometimes it lost connection with the server and literally "blocks", others don't save the files properly, other only load half of the ftp files, etc etc .. My question is: Is there a way to use ftp and notepad++ (without using its build-in ftp or a ftp client like filezilla)? I've tried using NetDrive, but it gets stuck sometimes (makes the editor crash), and everytime the temporary file is refreshed by windows / NetDrive, it will load the new file without asking and skip the pointer to the end of the file (very very very annoying). In case you know how to make the built-in notepad++ ftp plugin work at 100%, I'd be much more happy! I'd like to have some feedback from you guys :) (I'm using Windows Vista) Thanks in advance!

• Installing Debian 7.6.0 on Lenovo Y50

  - by Girauder

  I was trying to install Debian on my new laptop: a Lenovo Y50 64bit running Windows 8. I got together with a friend and installed Debian in his computer first and had no problems. However I've tried to install Debian several times using the AMD64 KDE and netinst versions and accomplished nothing. First try: installed the KDE version. Grub would let me choose which operating system I wanted, but when I selected Debian it would only load the command line. Second try: Reinstalled but this time with the netinst version. I only got a black screen where I could type but nothing else. Third Try. Tried the netinst again. This time after making the partitions I got a message that said that no EFI partition was found. I ignored the message and this time it wouldn't even load Grub. only a command like interface with grub rescue or something. Not once did I get an error during the installation. What am I doing wrong? I assume the problem is I need to make an EFI partition or something like that. So why is it that during the first installations I didn't ask me for that. And if that is indeed the problem, How can I solve it? Update So the installation failed again... as predicted. Here you can find the Disk Management picture. http://postimg.org/image/433cpfkjz/ Please somebody help me. I keep getting the grub rescue thing. secure boot is disabled and legacy support is set first.
