  • Battery backed write cache behavior upon disk change

    - by Halfgaar
    We use 3ware Inc 9650SE SATA-II RAID PCIe RAID controllers with battery backed write cache. Our spare hardware has the same controller. I was wondering; are these controllers smart enough not to sync the cache when the disks have been changed? For example, if I deploy one of those spare machines by putting in the disks of another machine and that spare machine still has pending writes, will it be smart enough not to perform those writes on the replaced array? Edit: my scenario is not really made clear, so let me give an example: server1 goes down because of power supply failure. I put the disks in server2 and start. I repair server1 I put the disks back from server2 in server1 (it's not relevant right now that in reality I would probably keep server2 running). If server1 doesn't have safeguards, it will write to the array, thinking it's simply powering up again, corrupting it.

  • Win7 safe mode pretends it's Xp?

    - by Joachim Kerschbaumer
    hi there, just a question in between. a friend of mine brougth me a laptop that does not work anymore and wanted me to check whether i can do something. she told me its windows 7, and startup screen and login screen look like it. howevere, as she gets a bluescreen on startup it is only possible to boot in safe mode where the system pretends to be windows xp sp3. the system also may have 1 gig of ram but the system itself states that it has 954 mb of ram which is a value i´ve never seen before. is there everything corrupt from operating system to hardware, or am i just a newbie that does not know that windows 7 pretends to be winxp sp3 in safe mode? or is this laptop just the victim of an illegal, crazy copy of xp sold as win7? maybe some strange chinese stuff? i also recognized that the startup screen of Outlook Express is pronounced as "Outllok Express" (no typo) i´m kinda confused, maybe someone could put light into this ;) thanks

  • Redhat 6 gui installation VS kickstart gives me different packages?

    - by jonaz
    If i do the graphical install and select basic server + aide and screen i get a system with 535 installed packages. If i look at the /root/anaconda-ks.cfg file in that freshly installed system i see: %packages @base @console-internet @core @debugging @directory-client @hardware-monitoring @java-platform @large-systems @network-file-system-client @performance @perl-runtime @security-tools @server-platform @server-policy @system-admin-tools pax python-dmidecode oddjob sgpio certmonger pam_krb5 krb5-workstation nscd pam_ldap nss-pam-ldapd perl-DBD-SQLite aide screen If i then install a NEW system using a kickstart only containing those packages i get 620 installed packages. So basicly my question is why does the system install almost 100 more packages when using kickstart compared to the GUI installation when the exact same packagegroups are selected?

  • Dell Dimension running Fedora12 does a "Sleeping Beauty" and I am not a "handsome prince"!

    - by Jim Dobbs
    Dell Dimension 2350 with a Pentium IV processor and integrated video and network chips running Fedora12 does a "Sleeping Beauty" and I, apparently, am not am not a "handsome prince"! The system puts video and network to sleep and it will not wakeup. I have heard of this problem on laptops, but this is a tower. Any ideas or help is appreciated. I tried to ping the network card from another system and ping fails. The logs indicate that the system continues to be active. Pressing keyboard short-cut keys makes the disk light blink but neither the video or network card comes alive. Failing all else, are there any Linux commands that I could schedule in cron to pulse video and network adapters hourly that will keep them awake? Or, should I wait on Fedora13? Before this machine, I built a Dimension 2400 with Pentium IV and it had the same problem. Fedora9 on the same hardware is fine.

  • Convert video files for Maemo (Nokia N900) using ffmpeg/mencoder

    - by Vikrant Chaudhary
    I'm a newbie in video encoding so I'm looking for some expert advice. I'm looking to transcode media files with ffmpeg or mencoder (or something other) on Ubuntu for my Nokia N900 running Maemo. I'd prefer mencoder, because of ffmpeg's crazy dependencies. Video output should be AVC/H.264 (probably hardware accelerated on device). Audio output in AAC (should have preferred Vorbis but not supported natively and requires .mkv which is also not completely supported). Output video should retain the original aspect ratio. Resolution of screen is 800x480 (16:10). (Explanation of why-this-value-is-chosen would be really appreciated). Thanks.

  • How do you check Driver Verifier logs on Windows 7 after catching a faulty driver?

    - by Wolf
    I kept getting BSODs on a clean install of Windows 7 (plus updates), so I decided to run Driver Verifier. I had to select all drivers, since it didn't catch the culprit when I didn't include Microsoft drivers. I know it is not a hardware problem since everything is working fine on Linux and memtest86+ is not reporting any errors in the RAM (8 GB). This time, it caught the faulty driver and gave me a BSOD telling me so. Using WhoCrashed, I could verify what was the last error message with the parameters and the source. Yet, the source is always the kernel (ntoskrnl.exe) and the bugcheck this time was 0xC4 (0x85, 0xFFFFF9804429AFC0, 0x2, 0x11B948). After searching on the web, I found out "the driver called MmMapLockedPages without having locked down the MDL pages." As I am not developing any driver, this is of no use to me. However, I would like to know which driver caused Driver Verifier to trigger an alert, so I can either disable it, or rollback to a previous version in order not to get crashes anymore.

  • Connect server to router with workstation in between?

    - by letseatfood
    I have a server (9 yr old Dell with Ubuntu 10.04 Server Edition) and a workstation (Laptop with Vista) which are both connected to a router. The workstation is able to access the server via web browser for testing my web development projects. Since the server is old and does not have a wireless card, I am wondering if it is possible to connect the server directly to the workstation while maintaining the ability to connect to the server from the workstation. The reason is that the computers are in a separate room from the router and I am trying to limit the amount of wires on the floor, along with trying to avoid buying more hardware (like a wireless card). Thanks and I will be more than happy to clarify!

  • Is it possible to have a portable plotter that can print QR codes on burlap?

    - by Brian Ballsun-Stanton
    This is a hardware question. Is there a class of plotters that are portable and accept sharpies? The use case: I have a burlap sack. It will be taking very specific potsherds from an archaeological dig. It needs an indelible QR code (or bar code) printed on the burlap. (Stickers have far far too short a lifetime). It was my thought that a plotter that uses sharpies and that works in the field would be the optimal solution for this problem. Is a portable plotter the right solution? If so, who makes them? If not, what is a better solution?

  • Does a portable secondary laptop LCD monitor exist?

    - by Dougnukem
    I'm looking to buy a portable secondary LCD monitor for my Macbook Pro, does anything like that exist? I found some laptops that provide a dual 15'' monitor solution (but it's already baked into the hardware). Also some ideas posted about creating this type of setup back in 2007. I'm looking for something that is as thin as a laptop LCD (with maybe a bulky power supply that I could easily daisy chain or plug into a power strip along with my laptop). How difficult would it be to buy a 17'' laptop screen and hook up a DVI connector and power supply, and build a simple monitor stand for it? I've gotten to used to a dual-monitor setup at work and at home with my laptop that having to use my laptop in single-screen mode makes me feel crippled.

  • OS Missing? Messed up the MBR on Win7 64-bit

    - by hom3lesshom3boy
    I have a Windows 7 machine with two hard drives: a 1TB C: drive and 500GB J:. I had Windows XP installed on C: and Windows 7 installed on J:. I installed Windows 7 after Windows XP from an installer .exe I (legally) bought and downloaded. It, and all of my other files, are sitting on my J: drive intact. While under my Windows 7 install, a few days ago I decided to use Priform's CCleaner and use its DriveWipe utility to wipe the C: drive. 1% into the process, I cancelled and attempted to use it again. It gives me an error saying it can't format the drive, so I poke around the Internet a bit, give up, and restart my computer. I first get an "OS is missing" error after the computer boots past the BIOS. I downloaded and put UBCD on a bootable USB to use another drivewiping tool to completely erase the C: drive, hoping it'll take the problem with it. No luck. I try to use TestDisk to make my J: my primary active drive, but no luck. I still get the "OS is missing" error. Or sometimes it'll hang at Verifying DMI Pool. Or sometimes I'll get the "NTLDR is missing" error. I get hold of Hiren's and put it on another bootable USB. I first I tried the Boot Windows 7 from Hard Drive option, and I get "Error 15: File Not Found". I tried the "Fix 'NTLDR is Missing'" option (I'm not quite sure why this is even showing up, since I'm trying to get into a HDD with Windows 7 installed. Probably messed up somewhere when I used TestDisk) and I get this list: I'll run through the error messages I get: 1st Try - Windows could not start because the following file is missing or corrupt: \system32\hal.dll 2nd Try - Windows could not start because the following file is missing or corrupt: \system32\ntoskrnl.exe 3rd Try - Windows could not start because of a computer disk hardware configuration problem. Could not read from the selected boot disk. Check boot path and disk hardware. 4th - 8th Try - Same as #3 9th Try - I/O Error accessing boot sector file multi(0)disk(0)fdisk(0)\BOOTSEC.DOS. And computer freezes. 10th Try - computer restarts Needless to say, not a single one of those works. I then tried to open up the Windows 7 exe I have sitting on my J: from the Mini-XP OS on Hiren's, but it won't run because I'm trying to run a 64-bit file from a 32-bit exe. At least, that's the problem according to these guys: http://social.technet.microsoft.com/...-b2f54e9c7d18/ I then borrowed a 64-bit Windows Home Premium CD from a friend to get to the recovery options. But I get the error message: This version of System Recovery Options is not compatible with the version of Windows you are trying to repair. Try using a recovery disc that is compatible with this version of Windows. I pressed Shift + F10 to get to the Command Prompt directly. These are the exact steps I took from there (paraphrased a little): X:\Sources>bootrec /Fixmbr The operation completed successfully. X:\Sources>bootrec /Fixboot The operation completed successfully. I restarted my computer, but it still didn't work. I unplugged the C: drive, then tried bootrec and Diskpart: X:\Sources> bootrec.exe X:\Sources> bootrec /RebuildBcd Total identified Windows installations: 1 [1] \\?\GLOBALROOT\Device\HarddiskVolume1\Windows Add installation to bootlist? Yes(Y)/No(N)/All(A):y The requested system device cannot be found. X:\Sources>DiskPart DISKPART> List Disk Disk # Status Size Free Dyn Gpt Disk 0_Online_465GB_0B_______* Disk 1 Online 1000MB 0B (this is Hiren's on a bootable usb) DISKPART> Select Disk 0 Disk 0 is now the selected disk.

The ACTIVE command can only be used on fixed MBR disks. DISKPART> exit Leaving Diskpart... X:\Sources>bootrec /Fixmbr The operation completed successfully. X:\Sources>bootrec /Fixboot The operation completed successfully. Before I go any further, is there anything I'm overlooking/doing wrong? All I care about is making the J: and Windows 7 bootable again. SPECS: Windows 7 Professional 64-Bit GIGABYTE - Motherboard - Socket 775 - GA-P35-DS3R (rev. 2.1) Crucial Ballistix 2048MB PC6400 DDR2 800MHz (2x2GB) Intel Core 2 Duo E6700 Processor (2.6 (6GHZ) I think... not sure anymore C: HDD - SAMSUNG HD103UJ (1TB, not plugged in) J: HDD - WDC WD5000AKS-00V1A0 (500GB)

  • Which WordPress plugin adds support for Java syntax highlighting? [closed]

    - by Bozho
    In wordpress.com-hosted blogs syntax highlighting is working, but on a newly privately installed WordPress blog it is not. So I assume there is a plugin for this. I tried wp-syntax and bbcode plugins - no success. So, which is this plugin, that allows programming language code to be highlighted: [code language="Java"] public class SomeClass {..} [/code] Update: I'm talking about the WordPress software, not the wordpress.com service. I was just giving an example (wordpress.com) of what is to be achieved.

  • mount dev, proc, sys in a chroot environment?

    - by Patrick
    I'm trying to create a Linux image with custom picked packages. I followed the guide here http://www.olpcnews.com/forum/index.php?topic=4766.0 However, when I tried to install some packages, it failed to configure due to missing the proc, sys, dev directories. So, I learned from other places that I need to "mount" the host proc, ... directories to my chroot environment. Though, I saw two syntax and am not sure which one to use. In host machine: mount --bind /proc <chroot dir>/proc and another syntax (in chroot envrionment): mount -t proc none /proc Which one should I use, and what are the difference? Edit: What I'm trying to do is to hand craft the packages I'm going to use on an XO laptop, because compiling packages takes really long time on the real XO hardware, if I can build all the packages I need and just flash the image to the XO, I can save time and space.

  • Can not run ifconfig like commands via browser

    - by savruk
    Problem is I cannot run "ifconfig" or similar commands via browser. Environment: Programming language : python Server : lighttpd(CGI) , running on busybox. Well machine is really small and so I am really restricted. Tried techniques: chown every script to root. But there is no differences. Why? Because lighttpd runs under another user, I mean not under root. As it is not root, when I try to run script from browser it always calls the python file with its uid. So it makes it impossible to run "ifconfig eth0 192.168.2.123" like commands via web browser. I get "ifconfig: SIOCSIFADDR: Permission denied" error. What can I do? I do not have any sudoers file, so cannot modify sudo command. Well, I don't even have "sudo" command :) Thanks for your help

  • Thinkpad Bluetooth turns itself on upon restart/hibernate

    - by Traveling Tech Guy
    I have a T400 with Windows 7 64bit. About 3 weeks ago, the Lenovo update pushed a Bluetooth update that added a 2.1 driver and device experience. Since then, my bluetooth turns itself on whenever the OS comes up (full restarts as well as waking from hibernation). I can turn it of using the <Fn>+<F5> Radio menu, but it just turns itself on again the next time. If I forget to turn it off, it just eats my battery that much faster.I've been scouring the web and couldn't find similar occurrences. Is this a hardware issue, a BIOS issue (although no reference to BT in any of the BIOS menus), a driver issue or (shudder) a user issue? Thanks for your help.

  • Windows Firewall failing after 9-12 hours?

    - by routeNpingme
    I have 2 VM servers in the exact same NIC configuration: Server 2003 R2, one NIC connected to private (hardware firewall) network in a 10.x private address space, and one NIC connected straight to public internet. Windows Firewall is enabled for the Public Internet NIC only. Now, what doesn't make sense - this fails generally after 9-12 hours. It's not exact, but once or twice a day, traffic will just stop on the Internet NIC. No event log entries when it happens, and restarting the Windows Firewall service as well as stopping or restarting IPSec Services (just for fun) has no effect. Once the server is rebooted, everything is fine again for another 1/2 day. Any suggestions?

  • Recommendation for PCI SATA addon card?

    - by edmicman
    I have a couple of dead PCs from my wife's office that have working SATA HDDs. Sorry, I don't know if they're SATA I or II, just that they're SATA. Unfortunately, all my spare hardware at home is pretty old; all I have is IDE support. I was thinking I could get a PCI addon card on the cheap that would support SATA and put together a budget server of sorts to play with and be able to use those drives. So I've got a couple questions: After some searching it looks like I can get an addon card for ~20 bucks, but it looks like they're all SATA I? Would that matter? It looks like going to SATAII bumps the price up to $40-$60 or so. Are there any recommendations on a card to get?

  • SCCM deploy from VMware XP image

    - by HannesFostie
    We recently set up the latest version of SCCM and I managed to capture a .wim image from a virtual machine (build and capture task sequence). I want to use this .wim file to deploy winXP to different hardware, and therefor need to add device drivers to the task sequence. I created a driver package per laptop type, and deployed for the first time. However, I am getting a BSOD (0x00007B) which leads me to believe theres a problem with the storage drivers. After adjusting the task sequence to try and point to the mass storage drivers (which are applied at F6, I suppose) I do not get a list of compatible drivers (the list is empty). I looked around, and found some issues regarding hdc class drivers that are not recognized as mass storage drivers. The workaround suggested changing the INF file to make the driver a SCSIAdapter class driver, and importing these again, but to no avail. The list remains empty. Any help is much appreciated

  • Multiple test Active Directory envirovments hand in hand with production domain controllers

    - by MadBoy
    What's the best approach of having multiple test environments next to production one? We have multiple programming teams that build solutions that use Active Directory very often. We have tried different approaches, starting with their own domain controllers (in same subnet), or additional OU's in our production AD that the team gets control over and can create/delete accounts within that one OU. We thought of possible 4 solutions: Setting up separate OU's in ou production env. Creating subdomains for our contoso.com domain like test.contoso.com, something.contoso.com and delegating control to the teams (would we need additional DC's or the two that we have already would be enough to hold this? Setting up additional test domain controler that has a trust to our main domain and all teams can use the test domain controler as they please. Setting up single domain controller for every team/project. We're taking in consideration amount of resources needed, security (for example having multiple domain controlers with multiple passwords may lead users to use simpler passwords) and overall best practices for this scenario.

  • Distributed, Parallel, Fault-tolerant File System

    - by Eddified
    There are so many choices that it's hard to know where to start. My requirements are these: Runs on Linux Most of the files will be between 5-9 MB in size. There will also be a significant number of small-ish jpgs (100px x 100px). All of the files need to be available over http. Redundancy -- ideally it would provide the space efficiency similar to RAID 5 of 75% (in RAID 5 this would be calculated thus: with 4 identical disks, 25% of the space is used for parity = 75% efficent) Must support several petabytes of data scalable runs on commodity hardware In addition, I look for these qualities, though they are not "requirements": Stable, mature file system Lots of momentum and support etc I would like some input as to which file system works best for the given requirements. Some people at my organization are leaning towards MogileFS, but I'm not convinced of the stability and momentum of that project. GlusterFS and Lustre, based on my limited research, appear to be better supported... Thoughts?

  • ZFS SAS/SATA controller recommendations

    - by ewwhite
    I've been working with OpenSolaris and ZFS for 6 months, primarily on a Sun Fire x4540 and standard Dell and HP hardware. One downside to standard Perc and HP Smart Array controllers is that they do not have a true "passthrough" JBOD mode to present individual disks to ZFS. One can configure multiple RAID 0 arrays and get them working in ZFS, but it impacts hotswap capabilities (thus requiring a reboot upon disk failure/replacement). I'm curious as to what SAS/SATA controllers are recommended for home-brewed ZFS JBODs. In addition, how does battery-backed write cache (BBWC) play into the solution?

    I can TELENT 192.168.10.10 3389 and get a connection. But RDP client to 192.168.10.10 immedietly bails (i.e less then 1 sec) "connect" button greys briefly, RDP app remains on screen. Have tried these from many nodes on the subnet to 192.168.10.10 with same result. On 192.168.10.10 Allow Remote Desktop is enabled. On 192.168.10.10 windows firemall is off. Im connecting from the same subnet i.e no firewall hardware / routers in the way. AV software is installed but other nodes on same subnet allow RDP connection using exact same AV settings (network group profile) Checked 192.168.10.10 for any additonal AV software or local firewall products. Im sure non exist. Checked regedit to ensure 3389 was the port set for listening. Seems to be an XP problem (sp3) ( 2 nodes on the my LAN have this issue) and many work fine.

  • Tracking down random BSOD on windows 7

    - by pehrs
    I have gotten a computer running windows 7 handed to me that randomly, several times a day, bsods with a PAGE_FAULT_IN_NONPAGED_AREA (50) or WHEA_UNCORRECTABLE_ERROR (124). Crashes happens regardless of load. I am running out of ideas for how to track this down. Analyzing the minidumps shows the crash to be in ntkrnlmp.exe/WMIADAP.exe System has plenty of power (600w) Ram checks out fine using memtest86+ over a weekend. System is clean inside. No dust build up. Temperatures stay low. As far as I know (and reliability history shows) no new drivers were installed for several months before the problems started. All drivers are now up to date. sfc /scannow reports the system as clean. CHKDSK reports the disks as clean Removing the AV (Avast) has no effect. Any more things that should be tried on windows 7 before I start replacing the hardware?
