• SATA Blu-Ray drive not detected via USB adapter

  - by LTR

  I'm using an SATA blu-ray drive (Lite-On IHOS104), connected via a USB adapter to my Windows 7 (32-bit) notebook. The first time I plugged the adapter in, it worked perfectly. The drive appeared in Explorer, and my player software was able to play an encrypted Blu-Ray disc just fine. After the first reboot, it never worked again. Now it shows up as "removable media" with a size of 0 bytes, irregardless of whether a disk is inserted or not. The drive does not show up under the green "eject USB device" icon in the taskbar. The adapter is powered using a separate power adapter. I have tried: disconnecting all other USB devices testing with a DVD instead of a Blu-Ray disc letting Windows search for updated drivers for the drive - there are none using the same drive and adapter on another Win7 (but x64) computer. They work perfectly. using other USB ports on the same notebook - tried them all. using a different SATA/USB-adapter What else can I do to diagnose this problem?

• SCCM 2012 Clients no longer detecting

  - by user3685428

  Here is the scenario I had a fully functioning SCCM 2012 site server with the DP, MP, SUP, Application catalog, etc. roles configured and working. There is only one server on this site. Everything was great but i was not happy with SUP, so i decided to create a separate WSUS server and configure Windows Updates through GPOs. That setup worked great as well so i went ahead and removed the SUP role from SCCM and removed the WSUS feature from my SCCM server (they were configured on the same SCCM Server). I did not notice any problems right away. A couple days later i noticed that the OSD deployments were giving errors, and after a couple hours of trying suggestions from Google, i was able to uninstall PXE and make a few changes and reinstall with WDS to get it working again. Again, thought everything was fine and continued on. The last couple days i have noticed that any new machine deployed or installing the Client will show in the SCCM console as "No" Client. The client machines will show connected to a site but the software center shows "IT Organization" instead of our site like the previous clients. The existing clients all seem to be functioning normally. they still receive application distributions and configuration baselines, etc. Reinstalling, uninstalling and reinstalling, repairing does not fix the problems and this happens on all new clients. ClientLocation.log shows it connecting to the correct MP. Nothing odd in any of the logs except for the ClientMessaging.log which repeats continuously this line: <![LOG[Raising event: instance of CCM_CcmHttp_Status { ClientID = "GUID:0450fde3-ab82-41bf-9c33-87a18113744b"; DateTime = "20140528214824.993000+000"; HostName = "SOUNDWAVE.domain.org"; HRESULT = "0x00000000"; ProcessID = 4092; StatusCode = 0; ThreadID = 3720; }; ]LOG]!><time="16:48:24.994+300" date="05-28-2014" component="CcmMessaging" context="" type="1" thread="3720" file="event.cpp:706"> thanks

• Remote Desktop Network Level Authentication Not Supported

  - by Iszi

  I'm running Windows XP Professional SP3 x86, trying to connect to a system with Windows 7 Ultimate SP1 x64. Recently, I updated the Remote Desktop Connection software on the XP system in hopes of using Network Level Authentication (NLA) for my connections to the Windows 7 box. After the update, I connected to the Windows 7 box over RDP and enabled NLA believing that the updated client should support it. After disconnecting and attempting to reconnect, I'm presented with the following error: The remote computer requires Network Level Authentication, which your computer does not support. For assistance, contact your system administrator or technical support. So, I checked the About page in Remote Desktop Connection to make sure the update had applied. This is what I see. Remote Desktop Connection Shell Version 6.1.7600 Control Version 6.1.7600 © 2007 Microsoft Corporation. All rights reserved. Network Level Authentication not supported. Remote Desktop Protocol 7.0 supported. I thought NLA was supposed to be a part of RDP 7.0 clients. Is there a component I'm missing somewhere?

• VMWare Guest Info - Wrong IP Returned

  - by Jon Bailey

  We're running a VDI environment with vSphere 4.0 and Oracle VDI 3.2.2 and are having a bit of a problem with users that connect to an IPSec VPN from within their VM. For some reason, once connected to the VPN, the VMWare API returns GuestInfo.ipAddress as the VPN IP rather than the primary IP of the only NIC on the system. The IP address shown in net[0].ipAddress is the correct address and is what vSphere client is reporting. Is there any way to get VMWare tools to report the net[0].ipAddress as GuestInfo.ipAddress? Below is sample output from the guestinfo.pl script. 172.16.1.2 is the example "bad" VPN address that our VDI software is seeing. VMXFLEX01 guestFamily: windowsGuest VMXFLEX01 guestFullName: Microsoft Windows XP Professional (32-bit) VMXFLEX01 guestId: winXPProGuest VMXFLEX01 guestState: running VMXFLEX01 hostName: VMXFLEX01 VMXFLEX01 ipAddress: 172.16.1.2 VMXFLEX01 toolsStatus: VMware Tools is running and the version is current.

• Map FTP folder to folder on different FTP server

  - by jolt

  In my team we work a lot with FTP. We upload and download files from several different servers daily. Currently every member of the team manages access credentials to each FTP server locally on their own machine. I am looking for a way to set up a central FTP server that we can connect to, and from there, navigate to folders that each represent one of the other FTP servers that we connect to daily. Something like this: In-house central FTP server: |- FolderA --> server A root folder |- FolderB --> server B root folder |- FolderC --> server C root folder A setup like this, would mean that we can manage access credentials on the central FTP server, and team members would only need to have the access credentials to the central FTP server, and from there they could navigate to the other servers through these "virtual" folders. We could potentially develop our own custom FTP server that just forward requests to the remote FTP servers, but i feel like something like this (or something similar) would already have been done. So I'm looking for pointers that could help us find software for Windows that could help us to simplify our current setup. Thank you! Similar (unanswered) question here: FTP management server

• Suggestions for Windows 8 migration [closed]

  - by Big Endian

  I'm thinking of migrating to Windows 8. At first I hated it, but I'm pretty sure the Windows 8 model is the future, and I don't particularly want to end up hating the future like my parents, frustrated and bewildered by anything past Windows XP. I'm currently running Windows 7 and my system has been accumulating some problems. It's probably an accumulation of issues from installing too much software, changing firewall settings, installing Ubuntu alongside Windows, and... well I'm not sure, but my computer has been buggy in unexpected ways lately (freezing and unfreezing, display driver crashing and recovering, and what I call "deep freeze/thaw cycle" where the mouse won't even move for a while). I'm good at solving computer problems, but I can't seem to get to the root of these and my best idea for fixing them is making sure I've backed up every file then re-installing the entire OS. Luckily for me, a new OS is just around the corner so this would be a good time to get two things out of the way at once. The problem I see is that the upgrade options I see are all "seamless". I don't want a seamless upgrade. I want to wipe the slate clean and start all over. Does this mean I will have to buy a full, new copy of Windows 8 rather than one of the cheaper upgrading options? Or does it not make since for me to go to Windows 8 given that I have a laptop, not a tablet? Maybe I should just re-install Windows 7, or even call good enough good enough, try to eliminate the bugs, and start with a fresh slate in 2-3 years after this computer eventually dies entirely from (inevitable) hardware failure. What would be the advantages or disadvantages and costs of each option, how would I go about upgrading to Windows 8 if that's the option I choose, and what is your personal opinion about my situation?

• Monitoring / metric collection for system collectives that change a lot in time (a.k.a. cloud)

  - by Florin Andrei

  When your server fleet doesn't change a lot in time, like when you're using bare-metal hosting, classic monitoring and metric collection solutions (Nagios, Munin) work well. But if the number of systems varies a lot in time, and may in fact vary rapidly, classic software is more difficult to setup and use. E.g., trying to make Nagios (monitoring) keep up with a rapidly evolving cloud infrastructure can be cumbersome. Same for Munin (metric collection). It's not just the configuration, but the way the information is conveyed to the user, or displayed, is inadequate for the cloud. What are some possible alternatives that work well with the cloud? The goals are to collect and display metrics (analog to Munin), and generate alerts when certain metrics go out of bounds or when certain services are unavailable (analog to Nagios), and do everything in a cloud-friendly manner. Some cloud providers offer monitoring / metric collection as services, but not always, and if you use more than one provider you don't want to become too dependent of just one vendor. So provider-independent solutions are required. EDIT: I am asking this question in a general fashion - not limited to any given cloud infrastructure (like OpenStack), but in the general case of using arbitrary cloud providers.

• Possible DNS issue after a reinstall of Windows Server 2000 (get off my lawn)

  - by cop1152

  I just replaced a drive on a Win2000 Server that replicates AD and issues out DHCP at one of our offices. I successfully joined it to the domain, setup range of IP's, etc, but am still having issues. I cannot RDC to it with name or IP. I can ping it, browse to it with Windows Explorer, and remote to it with some other software, but not RDC. The other issue is this: Users are unable to authenticate on it. They receive the message 'username or password incorrect' (or something like that). Changes made on the main domain controller seem to take forever to trickle down. The most significant entry in the DNS Server Log is Event ID 7062: The DNS Server Encountered a Packet Addressed to Itself. At least, I think its significant. The Directory Services Log shows numerous Event IDs 1265: The attempt to establish a replication link with parameters failed with the following status: The DSA operation is unable to proceed because of a DNS lookup failure. Does this make any sense to anyone? I feel like its something very simple that I am overlooking. Thanks in advance.

• How can I parse/ transform text log data before it gets captured in SCOM 2007 R2?

  - by Abs

  I'm pretty much a noob with System Center Operations Manager 2007, and I'm probably missing something pretty basic, but I'm stumped anyway. We're setting up monitoring on some of our servers, and we'd like to capture data from some plain text log files (e.g. DNS debug logs, DHCP logs). It looks to me like I can set up a generic text file monitoring rule and get events captured into the main Ops Manager database, but my understanding is that the whole line of text from the plain text log gets captured as one field. In an ideal world, we'd be able to parse or transform that log file data to make it easier to query later. Is this possible? Is it easy? Do I have to buy expensive 3rd-party software to do it? One more thing: it would be even better if there was a way to stuff this data into the Audit Collection Services (ACS) database instead of the main one, but I'll take what I can get. Any help would be greatly appreciated.

• What permission(s) does an application pool identity required to manage other application pools?

  - by Mr Shoubs

  I have a web site (used to manage various parts of our software) that needs the permissions required to start/stop other application pools. I've created a user and set the app pool identity to custom, however the web app still can't start/stop the app pools. I get the following Error: System.UnauthorizedAccessException: Filename: redirection.config Error: Cannot read configuration file due to insufficient permissions at Microsoft.Web.Administration.Interop.AppHostWritableAdminManager.GetAdminSection(String bstrSectionName, String bstrSectionPath) at Microsoft.Web.Administration.Configuration.GetSectionInternal(ConfigurationSection section, String sectionPath, String locationPath) at Microsoft.Web.Administration.ServerManager.get_ApplicationPoolsSection() at Microsoft.Web.Administration.ServerManager.get_ApplicationPools() Discussion here suggests setting the application pool to local system or administrator, this does work, but I don't want to do this for security reasons (external support will need access this site). I did give the user higher permissions (as suggested here), starting by making it part of the local administrators group, but initially this didn't work, and giving the user read/write/mod permission on C:\Windows\System32\inetsrv\config also didn't work. I must have done something wrong as local administrator now works, however this still isn't what I want. So can anyone suggest the permissions I need to add to this user, and how can I apply them? An answer my problem (but different question) is here, but to clarify, I think I need to give an individual user "IIS Runtime Operation Permissions", does anyone know how to do this, if indeed this is the permissions I require?

• Upgrading openSUSE 11.1 with Plesk Panel 9.3 to PHP 5.3

  - by Jonathan Hogervorst

  Hello, I'm running a VPS with openSUSE 11.1 (i586). On the VPS is Parallels Plesk Panel 9.3.0 installed. The current PHP-version is PHP 5.2.11. I want to upgrade PHP to PHP 5.3, but I can't find good instructions on how to do this. If I check for updates in Zypper, it says this is the latest release. In the Plesk Updates isn't an update either, both via the webbased interface and the command line interface. On Software.openSUSE.org I can find packages for PHP 5.3.1 in both the server:php/server_apache_openSUSE_11.1-repo and the server:php/openSUSE_11.1-repo (can't post the link because I'm a newbie here). But if I add one of those to Zypper, I still don't see an update. Is there here somebody who knows how to do this? And is it completely safe to update that way? I don't want to end up with a broken VPS... Thanks! Jonathan

• Acer recovering windows vista

  - by Charlie Pigarelli

  My computer history is very long even of my computer has 4 years of life. An year ago I installed Windows 7 on this acer m1610 that had Vista before. My technic left me 2 recovery disc for "acer vista" before updating it to Windows 7. Then the computer had some trouble. The graphic card broke and we decided to use another computer. Yesterday I had the great idea to fuse the two computer to have a better one... So I moved the graphic card of the latter computer to the acer and everything gone well. Then the trouble of speed, it had before, come back. So I decided to reinstall the very first Windows: Vista back again. I booted the computer with those 2 DVD-R my technic left me and at the end of the process it asked me to insert "the backup cd number one or the system disk". I found 2 original Acer "Blank Recovery Disc" DVD-R and tried with those: rejected. Tried with empty DVD-+R: rejected. I tried with CDs: rejected. I don't have any system disc with me. Except for those 2 DVD-R my technic left me. What am I supposed to do now? I even tried with these fantomatic alt+f9/f10 that should start the recovery without any disc... But nothing happened. PS: the installation cannot complete if I do not insert the right disk. (The recovery disc uses Acer eRecovery Management as recovery software.

• EEE PC dropbox server running 24/7

  - by microspino

  I'd like to create a mini dropbox and print server on a small soho network of 5 users (all of them use windows XP desktops). The device need to run 24/7 or at least 12/7 (I can accept just workday hours too but the other two options would be better). Dropbox mini server: I mean I will have a 90gb dropbox on every computer on my network LAN syncing with It and the one onto It syncing to the web. Print Server: I have Samsung SCX 4521F (fax/print/scan/copy), Samsung ML2010, HP Laser jet P1006, HP Color Laserjet CP1215, HP Office jet pro K8600, HP Design jet 500. All of them now are connected using little print servers and I want to get rid of them hooking everything to this mini server. The fax/print/scan/copy machine need to stay connected to a PC to make me able to use the software that comes with It. The mini server would save me on this too. Fax/Scan server: since I have the above mentioned fax/print/scan/copy machine I would like to make people use It from/to their computers through the mini server. I thought to a recent EEEBOX machine because I heard good things about ATOM cpus and because It seems that a recent BIOS version could switch It off and on autonomously. I'd like to listen some advice from You. Best of all would be: If You have something similar running for a long time If You disagree with this hardware choice and If You would suggest some other device. If You see any issues with my printing setup Anything else ;) My budget is from Zero (using right sw to build something on top on a old PC) to 500€ max.

• How to setup an IPSec / GRE tunnel on Windows Server 2008

  - by qbeuek

  I have a Windows Server 2008 that has a single network interface configured with a public IP address. My business partner has a private network. From my server, I need to access all the devices on his private network, and those devices must be able to access my server. My business partner has a standard solution for these requirements. They will setup an IPSec + GRE tunnel to my server. They told me, that I will need an additional public IP address for this to work. If it really is necessary, there is no problem, I can get an additional public IP address, although it will be assigned to the same physical network interface. I assume that on my server I will have both public IP addresses and also the private IP address from the tunnel (the same that is visible for the devices inside the private network). What alternatives do I have? Is it possible to configure this tunnel on my Windows Server 2008? Can it be done using only Windows tools, or do I need an additional free / commercial VPN software? If it cannot be done directly on Windows, can I setup an additional virtual machine running Linux, that will handle the IPSec + GRE tasks? How to do it? If it cannot be done on a virtual linux box, will I have to buy and setup a Cisco router to handle the IPSec + GRE tasks? Thanks for your opinions. I'm watching this question to clarify any issues or questions.

• Edit-text-files-over-SSH using a local text editor

  - by Mikko Ohtamaa

  I am working in various Linux and UNIX environments. I'd like to elegantly solve the problem of editing remote configuration files over SSH. Instead of using terminal editors (nano), I'd like to open the file in a local text editor on my desktop (Sublime Text 2). CyberDuck, WinSCP and various other SFTP apps can do this. Using editors over X11 forwarding has also proven to be problematic. Also using archaic text editors like Vim or Emacs do not serve my needs well. They could do this, but I prefer using other text editing software. Using ssh mounts (FUSE) are also problematic unless they can happen on the demand and triggered by the remote site. So what I hope to achieve Have a somekind of easily deployable shell script etc. which I can copy to remote server (let's call it mooedit) I run mooedit command on the remote server of which I have connected over SSH connection mooedit sends some kind of signal (over SSH( to my local desktop On my local desktop this signal is captured and it determines 'a ha! moo wants to edit a file on server X in folder Y' File is SFTP transfered to the local desktop (/tmp) File is opened in a nice GUI text editor on the local desktop When Save is pressed, the local desktop notices changes in the file and SFTP sends the resulting file back to the server The question is: What signaling mechanisms SSH provides for this? Any other methods to trigger a local text editor for remote SSH file?

• Windows 7 - Windwos XP - sharing - why isn't working?

  - by durumdara

  Hi! This is seems to be "hardware" and not "software" / "programming" question, but I need to use this share in my programs, so it is "close to programming". We had an XP based wireless network. The server is XP Professional, the clients are XP Home (Notebooks). This was working well with folder sharing (with user rights, not simple share). Then we replaced the one of the notebook with Win7/X64 notebook. First time this can reach the server, and the another client too. Later I went to another sites, and connect to another servers, another networks. And then, when I return to this network, I saw that I cannot connect to this server. Nothing of resources I see, and when try to dbl click on this computer, I got login window, where I can write anything, never I can login... The interesting part, that: Another XP home can see the server, can login as quest, or with other user. The server can see the XP home notebook. The Win7 can see the notebook's shared folders, and XP home can see the Win7 shared folders. The server can see the Win7 folders, BUT: the Win7 cannot see the server folders. Cannot see the resources too... The Win7 is in "work networking group", the group name is not mshome. I tried everything on the server, I tried to remove MS client, restore it with simple sharing, set guest password, etc., but I lost the possibilities to access this server from Win7. Does anyone have any idea what I need to see, what I need to set to access these resource - to use them in my programs? Thanks for every info, link: dd

• Photoshop CS6 Corrupted File recovery

  - by Ben Franchuk

  Last night I was working on a client application mock-up in photoshop, but was goin to take a break from my work so I saved the .PSD file on my internal HDD and put my computer into stand-by mode once the file had finished saving. Unfortunately my computer crashed while it was entering stand-by and shut itself down (photoshop was still open). I did not boot it again to make sure all my files were ok because they had already been saved, but today once I opened up the file again it was extremely corrupted and also completely un-editable (screenshot bellow). so what im asking is there any way to recover my work, or at least some of it? i have put in a good few days work on this project and would hate to have to restart it. the size of the file is 3070 KB, even though it reads as 712 KB in photoshop. i dont know if these file sizes are larger or either smaller than the original non-corrupted file's size, but considering all the layers in the file i suspect it was larger before it corrupted. im using windows XP professional 32bit SP3. both my OS and said .PSD file are located on the same internal HDD (74.4 GB). i do have an external HDD (1.5 TB) but i primarily only use it for movies music and tv shows. i dont know if it was plugged in t the time of me editing the document last, though, if it means anything. i have tried many image and PSd recovery softwares but none have returned any results that may help recover my work. edit: i tried using a photo reccovery software (odboso Photorecovery) that actually seems to recover the corrupted file in question judging by the size of the file, but i cannot recover it because of the licence fee. knowing that the file is still likely on my HDD, what location might it be located?

• How can I unregister a service with dns-sd?

  - by Roman

  I am trying to use "dns-sd" command line tool on my Windows 7 machine. I can already do something. For example I can register a service using "dns-sd -R ...". I also can browser (see) registered services using "dns-sd -B ...". What I still miss, is how to unregister a service. At the moment when I type "dns-sd -R ..." the dns-sd does not return me to the command prompt. To return to the command prompt I need to press Ctrl-C. And the service stays registered till I press Ctrl-C. What I want is to run "dns-sd -R ..." in the background regime and then I would like to have a possibility to unregister a service from the command line. One more thing which I do not understand yet is what "to look up a service" means. In my picture it should be sufficient to register a service, to see it and then to unregister it. But apparently I need to look up a service. What does it mean and why I need to do it? ADDED: As it is asked, I clarify. I refer to "dns-sd" command line tool which I use in Windows 7. I think this command is part of Bonjour software for Windows (from Apple). Well, I did not checked if I had this command before I installed Bonjour, but I assume I did not have it. So, my question is about this command.

• Load Sharing Regarding Large Websites

  - by JHarley1

  Hello, I have a question regarding Load Sharing for large websites. My Understanding: So if you have a website that has millions of fits a day you will need to have an architecture that can support this sort of pressure. You can either do one or two things: Invest in a single large server that has huge amounts of processing power, memory and storage (such as Microsoft's TerraServer). Spread the load of your website across a number of machines. Let me tackle the second approach, so you have a collection of machines all running Web Server Software and all having access to identical copies of the websites pages. You can either spread the load across these machines using a cyclic pattern in a DNS or you can use a Load Ballancing Switch. The advantages of this approach is: - Redundancy - servers can fail and the others would "pick up the slack" - Incremental - the ability to easily add new machines to this set-up. My Question's Is there a Virtual approach to this issue of load balancing now? If the website runs from a database - is there still only a single copy of the database? If a user had a session running on one Server (e.g. they had gone to www.example.org and had been assigned to Server 2 - were they had created a session) if they refreshed the website (and were allocated Server 3) would they still have their session? What are the other disadvantages associated with Load Balancing? Many Thanks, J

• NX Client for Windows 7 Opens Remote Desktop in Multiple Windows

  - by Corey Kennedy

  What I'm trying to do: access my Ubuntu desktop remotely via NX Client on my Windows 7 laptop. My environment: server: Ubuntu 10.10 on AMD 1Ghz/512MB RAM PC client: Windows 7 on ThinkPad sl510 Software: server is running NXServer 3.4.0. Using xfce4 window manager. Laptop is using NXClient for Windows In my NX Client "Desktop" settings I've selected "Unix" and "Custom" for OS and environment. I've also specified "startxfce4" as the application to launch when NX connects. I am able to authenticate an NX session on my laptop. By this I mean, I can start the client on my laptop, enter credentials for my Linux user, and NX establishes a connection to the server and attempts to open a remote desktop window. The problem, though, is that this remote desktop is "fragmented" into many Windows. One window will display the bulk of my desktop (complete with desktop icons for "Home," "File System," and "Trash") while another window will contain the taskbar, and another window will contain the application strip. I can select each of these Windows individually, but I cannot click on any objects within them. I've searched Super User, Ubuntu Forums, NX help, Server Fault, and tried many Google searches - none have turned up another case of this particular problem. I'm stumped. Does anyone have any suggestions for what I might try? I'm guessing the problem has to do with my xfce config files, but I've only just setup this server - it's been a long time since I've used Linux and there's a lot I just don't know. What I am NOT trying to do: use Desktop sharing from Ubuntu, whereby I VNC into a desktop that I've already established on the server. I am trying to configure this Linux box as a headless server that I can stash someplace out-of-the-way in my house, then interact with through my laptop. I don't want to have a monitor or keyboard connected to the Linux box. Thanks for your help!

• Best way to 'harden' embedded ext4 file server against unexpected loss of power?

  - by Jeremy Friesner

  Hi all, First, a little background: my company makes an audio streaming device that is a headless, rack-mounted Linux box with a couple of SSDs attached. Each SSD is formatted with ext4. The users can connect to the system using Samba/CIFS to upload new audio files or access existing ones. There is also custom software for streaming out audio over the network. This is all fine. The only problem is that the users are audio people, not computer people, and see the system as a 'black box', not as a computer. Which means that at the end of the day, they aren't going to ssh in to the box and enter "/sbin/shutdown -h"; they are just going to cut power to the rack and leave, and expect things to still work properly the next day. Since ext4 has journalling, journal checksumming, etc, this mostly works. The only time it doesn't work is when someone uploads a new file via Samba and then cuts power to the system before the uploaded data has been fully flushed to the disk. In that case, they come in the next day and find that their new file has been truncated or is missing entirely, and are unhappy. My question is, what is the best way to avoid this problem? Is there a way to get smbd to call "sync" at the end of every upload? (Performance on uploads isn't so important, since they only happen occasionally). Or is there a way to tell ext4 to automatically flush within a few seconds of any change to a file? (Again, performance can be sacrificed for safety here) Should I set a particular write-ordering mode, activate barriers, etc?

• File corrupted by some tools (probably virus or antivirus)- does the pattern indicate any known corruptions?

  As part of our software we install postgres(windows). In one of the customer sites, a set of files got corrupted. All files were part of timezone information(postgres/share/timezone). They are some sort of binary files.

• Ubuntu Server mdadm drbd ocfs2 kvm hangs under heavy file reading

  - by Stefano Annese

  I have deployed four ubuntu 10.04 server. They are coupled two by two in a cluster scenario. on both sides we have software raid1 disks, drbd8 and OCFS2 and on top of it some kvm machines run with qcow2 disks. I followed this: Link corosync is just used for DRBD and OCFS, the kvm machines are run "manually" When it works is fine: good performances, good I/O, but at a given time one of the two cluster started hanging. Then we tried with just one server turned on and it hangs the same. It seems to happen when an heavy READ in one of the virtual machines occurs, that is during rsyn backup. When the fact occurs the virtual machines are not reachable any more and the real server responds with good delay to the ping but no screen and no ssh is available. All we can do is force shutdown (hold the button) and restart and when it turns on again the raid on which relay drbd is resyncing. All the time it hangs we see such fact. After a couple of week of pain on one side this morning also the other cluster hung, but it has different moteherboard, ram, kvm instances. What is similar is reading for rsync scenario and Western Digital RAID Edistion disks on both side. Can anybody give me some input to solve such issue?

• Why are SMART error rates going down?

  - by Jeff Shattock

  I have a hard drive that's part of a Linux software raid5 array. SMART has reported that its multi_zone_error_rate was 0, then 1, then 3. So I figured I better start backing up more frequently and prepare to replace the drive. Now, today, the multi_zone_error_rate of that very same drive is back down to 1. It seems that 2 errors unhappened while I wasn't looking. I've also seen simliar behaviour by inspecting the syslog on the server. Jun 7 21:01:17 FS1 smartd[25593]: Device: /dev/sdc, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 7 21:01:17 FS1 smartd[25593]: Device: /dev/sde, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 7 21:01:18 FS1 smartd[25593]: Device: /dev/sdg, SMART Usage Attribute: 7 Seek_Error_Rate changed from 200 to 100 Jun 8 02:31:18 FS1 smartd[25593]: Device: /dev/sdg, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 Jun 8 03:01:17 FS1 smartd[25593]: Device: /dev/sdc, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 Jun 8 03:01:17 FS1 smartd[25593]: Device: /dev/sde, SMART Usage Attribute: 7 Seek_Error_Rate changed from 100 to 200 These are raw values, not the human-useful values that smartctl -a produces, but the behaviour is similar: error rates changing, then undoing the change. None of these are the drive that had the multi_zone weirdness. I haven't seen any problems from the RAID; its most recent scrub ( < 24 hours ago) came back totally clean. The only thing I can think of is that the SMART reporting circuitry on the drive isn't working properly all the time. The cables are in tight on the drive and board. What's going on here?

• Enable CPU fan always on

  - by Gundars Meness

  I am using 3 years old overheating laptop and I want my CPU fan to be spinning 24/7 regardless of the consequences. How to make it spin? The problem is that CPU & GPU heats up to 68°C (154 F) right after boot and never goes down, because CPU fan is not spinning full throttle. It starts spinning faster when temperature goes over 70°C and stops when it reaches seventy again. When doing heavy work on databases, it gets from 70 to 90 in no-time and automatically powers off. Bios does not contain any "fan spin 100%" options, just "spin slowly all the time" and "auto" which is more useless than the first one since my fan doesn't have pwm wire. Currently I'm solving this with cooling stand (3x5V), but it isn't much of a help. I would rather use the CPU fan since it is the only fan directly responsible for cooling down CPU/GPU. But how to make it spin 100% all the time? Should I attach it's red power wire to motherboard to get constant 5V (is there such option?), or is there an option to control it via software? Laptop: Samsung R528 2.3 GHz Intel i3 with Nvidia GeForce 310M Bios: Phoenix 03KT.M003.20100622.KSJ (and that is latest update) OS: Ubuntu 12.04.2 LTS with 3.2.0.51 kernel CPU fan: Image/Description Has 5V 0,4A and only 3 pins, no pwm. P.S. Yes, I did clean everything with alcohol, freed the air vents, changed thermal paste etc; that reduced temperature by 4 degrees.
