• Linux software raid fails to include one device for one RAID1 array

  - by user1389890

  One of my four Linux software raid arrays drops one of its two devices when I reboot my system. The other three arrays work fine. I am running RAID1 on kernel version 2.6.32-5-amd64. Every time I reboot, /dev/md2 comes up with only one device. I can manually add the device by saying $ sudo mdadm /dev/md2 --add /dev/sdc1. This works fine, and mdadm confirms that the device has been re-added as follows: mdadm: re-added /dev/sdc1 After adding the device and and allowing the array time to resynch, this is what the output of $ cat /proc/mdstat looks like: Personalities : [raid1] md3 : active raid1 sda4[0] sdb4[1] 244186840 blocks super 1.2 [2/2] [UU] md2 : active raid1 sdc1[0] sdd1[1] 732574464 blocks [2/2] [UU] md1 : active raid1 sda3[0] sdb3[1] 722804416 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 6835520 blocks [2/2] [UU] unused devices: <none> Then after I reboot, this is what the output of $ cat /proc/mdstat looks like: Personalities : [raid1] md3 : active raid1 sda4[0] sdb4[1] 244186840 blocks super 1.2 [2/2] [UU] md2 : active raid1 sdd1[1] 732574464 blocks [2/1] [_U] md1 : active raid1 sda3[0] sdb3[1] 722804416 blocks [2/2] [UU] md0 : active raid1 sda1[0] sdb1[1] 6835520 blocks [2/2] [UU] unused devices: <none> During reboot, here is the output of $ sudo cat /var/log/syslog | grep mdadm : Jun 22 19:00:08 rook mdadm[1709]: RebuildFinished event detected on md device /dev/md2 Jun 22 19:00:08 rook mdadm[1709]: SpareActive event detected on md device /dev/md2, component device /dev/sdc1 Jun 22 19:00:20 rook kernel: [ 7819.446412] mdadm: sending ioctl 1261 to a partition!

• Reboot loop after sysprep of AD machine

  - by rboarman

  Major screw-up here and I need to find out how much trouble I am in. I have an AD machine that is running Server 2008 R2, hyperv, DHCP and DNS. On the hyperv machine, I have a backup AD instance running along with a handfull of other server 2008 instances. Sysprep was run on the hyperv machine instead of one of the instances. I am attempting to bring the machine back up so I can try a system restore. When I boot the hyperv machine, I get an error that says “Windows could not complete the installation. To install windows on this computer , restart the installation” This message occurs in safe mode, AD restore mode and in last known configuration mode. How can I get my OS to boot at this point? Do I need to reinstall 2008 R2 from scratch?

• How do I get around "Access is Denied" [Number: 5 (0x80070005)], with IIS6/FastCGI and PHP 5.2.3?

  - by Evan Carroll

  I'm getting this error with IIS 6.0 (i assume), and PHP 5.2.3, and FastCGI FastCGI Error The FastCGI Handler was unable to process the request. Error Details: Error Number: 5 (0x80070005). Error Description: Access is denied. HTTP Error 500 - Server Error. Internet Information Services (IIS) Any ideas, nothing revealings in logs (other than 500 errors), this is pretty much all of I have to work with. The script has read and execute privileged for the internet guest account; and, I've added read/execute privileges to the whole D:\PHP. I followed this tutorial http://learn.iis.net/page.aspx/247/using-fastcgi-to-host-php-applications-on-iis-60/ to set it up. The only major diversion is I installed PHP to D:\PHP

• RAIDZ vs RAID1+0

  - by Hiro2k

  Hi guys I just got 4 SSDs for my FreeNAS box. This server is only used to serve a single iSCSI extent to my Citrix XenServer pool and was wondering if I should setup them up in a RAIDZ or a RAID 1+0 configuration. This isn't used for anything in production, just for my test lab so I'm not sure which one is going to be better in this scenario. Will I see a major difference in speed or reliability? Currently the server has three 500GB Western Digital Blue drives and it's dog slow when I deploy a new version of our software on it, hence the upgrade.

• SBS2003 OWA not displaying images on external side

  - by JasonC

  I've got an SBS 2003 server with companyweb/remote owa site. After authenticating remotely to the https:/servername/remote site, and then clicking on Use Outlook Web Access, the mail/owa site displays only limited amounts of data with Loading... displayed (see first image). This is different when viewing the site on the server itself (see second image). Different browsers will display different types of data (last screenshot is Chrome - first two are IE). I feel IIS permissions on the virtual directories is the cause, but not certain. Forms-based authentication etc is working ok etc. Any suggestions? Authentication and getting email via ActiveSync is not a problem. I don't want to break anything, and it's not a major problem because the users only get their email via outlook and iphones anyway without problems. I'm more interested in finding out for my own info so please give me some suggestions to try. Thanks for looking!

• How to install specific version of MySQL?

  - by user85569

  I installed from the repo, 5.0.77... including setup of PowerDNS (and the backend for MySQL). I tried setting up replication from my Master (which is MySQL 5.1.53) but it didn't work even though there were no errors, nothing got replicated. So the last resort is to try the same MySQL version on both the master and the slave (nb, only the slave has pdns installed) How would I go about installing MySQL 5.1.53? I tried downloading the rpm from MySQL (obviously the wrong one, didn't even include the mysql command to shell into the databases), but in turn fucked up the dependencies for pdns' mysql backend. I have the atomic repo which will install MySQL 5.5 (both on my Master server and Slave), but I don't want to do a major upgrade on the master right now as it's in production. Would love some advice!

• Snow Leopard tzdata

  - by pgb

  I live in Argentina, and our DST rules change often. So often, that major OS' tend to ship with an old version of tzdata DBs. In the past, I successfully updated the time zone databases in Tiger and Leopard. Today, however, when trying to update it in Snow Leopard, it did not work. Not only it failed, but now even after I reverted my changes, there seems to be some "cache" where the time zone information was retained. The files I updated (and reverted) are located at: /usr/share/zoneinfo and /usr/share/icu. To update those, I grabbed Apple's source code for ICU and recompiled it's database using the latest tzdata file (2010b). Then, I recompiled the tzinfo by running zic, and copied all the files to the system folders. Does anyone have experience dealing with Snow Leopard's timezone DB and can help? Thank you.

• The User Profile Service

  - by Daryl Gill

  I tried logging into my computer after an "ungraceful" shutdown due to a power cut.. I got prompted with a message stating the user profile service failed the login. After reading a k/b on Microsoft I managed to re-login to the "corrupt" account by making registery edits.. But the next step (After having the ability to logon) is a major concern for me.. Would the guys at superuser suggest: 1) Carry on using said account 2) Re-install Windows to eliminate the possible chance of a reoccouring problem 3) Migrate all user data over to a new account and with that being said above. I had to issue the command line: net user administrator /active:yes to activate the hidden adminstrator account, would it be recommended/secure to disable the account or leave it active?

• How can I provide secure web content to mobile devices that can't access an intranet?

  - by evanmcd

  I'm working with a client on development web content for their intranet. We want users to be able to access a version of the content on their mobile devices, but most of them don't have the VPN capability to get on to their intranet. I'm wondering if anyone has had experience with this and can recommend a solution. One other thing to consider is that the content is not mission critically secure. If someone outside the company gained access to it, it would not represent a major issue, only a minor annoyance. Thanks for any advice.

• Dell R510 vs R710

  - by AX1

  Hello, the Dell R510 and R710 can both hold regular configurations (e.g. X5650, 24 GB RAM, etc.) and these usually come out to about the same price. Is there a particular reason why one would choose the R510 over the R710 or vice versa? There really appears a lack of differentiating factors. The only 'major' factor I found, which doesn't apply to me though, is that the R510 can hold up to 12 3.5in HDDs while the R710 (which is slightly more expensive) can only hold up to 6 3.5in HDDs. Maybe you guys have some input and bought either of these machines (or both) to shed some light on other differences and why someone should choose one over the other as the pricing is pretty much the same with my configuration. Thanks!

• Speedup vmware esx guest hdd access

  - by Uwe

  Hello, we run several windows servers and windows clients on our vmware esx. One of the Windows 2003 Servers is a build-server with major HDD-reads/writes. as it is our build server. This machine was a hardware before and was virtualized to the ESX. Is there any way to increase the HDD-Performance? Perhaps there are special windows (guest) drivers? The files are stored on a Raid6 base. Performance graph of vmware infrastructure client shows reads up to 650 KBps and writes up to 4000 KBps. Thank you. Regards, Uwe

• Windows XP won't boot after drive transplant

  - by Nathan

  Hi all, I moved my hard drive from my Lenovo laptop into my Asus Eee PC netbook. When I started the netbook, after POST all I got was a black screen with a cursor in the upper left corner. I thought that the migration should work OK because this was a 32-bit version of Windows XP, and the Atom processor in the Asus should support the x86 instruction set. However, I don't know much about Windows, so maybe this was a dumb thought. I did verify that the BIOS can find the drive. It required major surgery to replace the drive, so any solution requiring me to remove the transplant drive is not going to fly. Keeping in mind that the netbook has no optical drive and that I have no other Windows computers (all my other computers run Linux), is there any way I can fix this problem? Thanks! Nathan

• Do different operating systems have different read and write speeds?

  - by Ivan

  If I have two different operating systems, such as Windows 8 and Ubuntu, running on the same hardware, will the two operating systems have different read and write speeds? My guess is that there would be minimal difference between operating systems and read and write speeds to the hard disk since the major limited factor is seeking; however, different operating systems may use different file systems in order to attempt to reduce seek time in the hard disk. Likewise, I'm sure that modern operating systems will not actually write directly to the hard disk, and instead will just have it in memory and marked with a dirty bit. Are there any studies that show differences in read and write speeds between OSs? Or would the file system being used by the OS matter more than the OS itself?

• Local Password Management

  - by ultimazombie88

  In our office (and I am sure many others) we access various websites and tend to share one account with our team. For example, we share credentials to Ebay and change them every few weeks to maintain some sense of security. However, we know this does not allow for any type of accountability for major changes. After some discussion we want to try to manage how we distribute credentials for sites that may not offer child accounts. Is there any smart and safe way to do this? If so how do you do it?

• Active Desktop cannot be restored on Win XP

  - by Phil.Wheeler

  This is more of a major annoyance than anything that's stopping me from doing my work, but I somehow seem to have had Active Desktop on my work XP machine get corrupted and now can't get it back working again. I've tried browsing to C:\Documents and Settings\%my-user-name%\Application Data\Microsoft\Internet Explorer and changing, deleting or replacing the Desktop.htt file, but it's not achieving anything. The error I was previously getting when trying to click the "Restore my active desktop" button was: Internet Explorer Script Error An error has occurred in the script on this page. Line: 65 Char: 1 Error: Object doesn't support this action Code: 0 URL: file://C:/Documents%20and%20Settings//Application %20Data/Microsoft/Internet%20Explorer/Desktop.htt Any ideas?

• Event Viewer shows service name as a truncated 8 character name

  - by Retrocoder

  I have written a service which logs to the Windows Event Log when it has any problems. This works fine and the service name is shown correctly in the Source column of the Event Viewer. The problem I am seeing is when my service hits some major problems like the networking layer has died etc. When this happens the event log shows errors about my service but the service name is shown as a truncated 8 character name. This name looks to be that of the executable and not the service name. Is this normal behaviour for a truncated name to be show ?

• Smarter System Alerts

  - by mellowsoon

  We have a pretty simple system setup, where I get text messages when there is a system problem. It's nothing fancy. I send an email to my phone number within my logging class for alert levels. It works well enough, but it has one major flaw: A small hiccup in the system/site can turn into dozens of rapid fire text messages. Sometimes non-stop text messages until I log into the system and fix the problem. So I'm looking for pointers on software or services I can use that deal with alerts in a smarter way. Perhaps something that only sends me alerts X number of times within Y number of minutes. I'm not looking for a full monitoring suite. We already deal with that in house. I'm only looking to tackle this single problem.

• Apache not running from rc.d on FreeBSD

  - by Oksana Molotova

  I'm using FreeBSD 8.3 and Apache 2.2. I didn't install Apache from ports, instead compiled it from source because I wanted to move the binary and configuration to a different path (I'm centering all of the major production daemons and their configurations in a single place). In any case, I based the /usr/local/etc/rc.d/apache22 file on one from a different server where it was installed from ports, I only modified the binary and config paths within. I can manually execute it with /usr/local/etc/rc.d/apache22 start, however even with apache22_enable="YES" in /etc/rc.conf it fails to start. All permissions and ownership are identical to the other server where it works. What am I missing and is there a way to debug this kind of thing?

• DNA and Quantum computing

  - by Jacques

  I recently(A couple of weeks ago) read an article about the future of processing and how quantum-processors and DNA-processors(DNA-computing) are the future competitors of computing since both will completely outperform the computers of this era. In terms of processing speeds, what do we expect from these two different processing techniques ? Personally I believe that DNA-processing will be a major step towards AI. For labs and office work I think quantum-processing which will be more logical. I'm quite excited that i'm still so young - to see what the future of technology holds! Then again my parents will soon find out what the after-life holds... just as bloody exciting, if not more..

• How to remove package from apt-get autoremove "queue"

  - by Darth

  I just installed Calibre for ebook management via apt-get on Ubuntu 10.04, however I found out that it's one major version behind the current release, so I decided to reinstall it directly from sources. When I uninstalled the packaged version, apt added bunch of dependencies to the autoremove queue, and as I installed newer version of Calibre from sources, it has no knowledge of it being dependent on those packages. Now I basically have all libraries that I want, but they are still in the autoremove queue. The following packages were automatically installed and are no longer required: libqt4-script libqt4-designer libqt4-dbus python-lxml python-cherrypy3 python-encutils libqt4-xmlpatterns libqt4-help python-qt4 python-clientform python-sip python-django python-mechanize libqt4-svg python-django-tagging libphonon4 libqt4-xml libqt4-assistant libqt4-webkit libqt4-scripttools python-beautifulsoup python-pypdf python-dateutil python-cssutils Use 'apt-get autoremove' to remove them. How do I tell apt that I want to keep these packages installed, without reinstalling them manually?

• Why am I having DNS problems going through Network Solutions DNS to Amazon AWS?

  - by BestPractices

  Network Solutions appears to have an issue with AWS hostnames. This AWS ELB has been out there for months and is resolvable from every major DNS provider but network solutions. Any idea as to why?

• Citrix Secure Gateway not redirecting to login URL

  - by Dave

  We have an older setup for XenApp - users log in through Citrix Secure Gateway running on a windows box. (We hope to start using a NetScaler soon.) Earlier today, connections to https://citrix.company.com/ starting throwing up a 503 error page, instead of redirecting to https://citrix.company.com/Citrix/XenApp/ If you go directly to the /Citrix/Xenapp/ URL, the user is properly directed to the login page, and can launch apps. We've restarted the service, and rebooted the server. We haven't yet tried uninstalling and reinstalling the software. Before we do this, I'm looking for ideas as to how we can get the redirect working again without a fairly major outage window. To make things more interesting, many of our users have Citrix Receiver installed, also pointed at https://citrix.company.com/. Receiver makes itself the default launcher for ICA files, and gives a connection error when it tries to load apps - probably because of the same non-functional rediect?

• Performance difference between MacBook Pro (2.8 GHz) vs Air (1.7 GHz)?

  - by jonathanconway

  I'm comparing these two Apple laptops: MacBook Pro (13", 2011 model): 2.8GHz dual-core Intel Core i7 processor with 4MB shared L3 cache 4GB (two 2GB SO-DIMMs) of 1333MHz DDR3 SDRAM AMD Radeon HD 6770M graphics processor with 1GB of GDDR5 memory on 2.4GHz configuration MacBook Air (13", 2011 model): 1.7GHz dual-core Intel Core i5 with 3MB shared L3 cache 4GB of 1333MHz DDR3 onboard memory Intel HD Graphics 3000 processor with 384MB of DDR3 SDRAM shared with main memory There's definitely a gap between them in terms of CPU speed and graphics, but what practical difference would this make on a day-to-day basis? On the one hand, I love the sleek, thin appearance of the Air. On the other hand, I don't want a machine that's going to be dog-slow when doing tasks such as running Virtual Machines, dual-booting to Windows and running multiple instances of Visual Studio, and maybe some light gaming. Is there going to be a major difference that makes the MacBook Pro a more attractive purchase?

• Any way to get P4V to work with older servers?

  - by 280Z28

  I use P4V as a Perforce client. I updated to 2009.1 to get some major bug fixes, and it seems they removed the ability to connect to older clients. I do work for a few clients, and 5/6 depots I have to work with are new, but one is older (2002.2 I think). Does this mean that not only I can't get any more bug fixes because 1 of 6 servers is old, but now I'm completely locked out of that server since the older P4V clients are no longer online? I know the 2007.x version I used before works with the old servers, but I can't find it online. Please tell me I'm not SOL... The Visual Studio integration is part of the P4V package, not the P4Win package, so if something isn't fixed I might never have VS support for P4 again. Help :(
