  • SCVMM 2008 R2 problems migrating VM from VS2005 to Hyper-V host

    - by Scott Ivey
    I have System Center Virtual Machine Manager 2008 R2 installed, and have a Hyper-V R2 host and a Virtual Server 2005 host. I'm trying to migrate my machines from the VS2005 host to the Hyper-V host, and keep getting the following error... VMM is unable to complete the requested file transfer. The connection to the HTTP server myserver.mydomain.local could not be established. (Unknown error (0x80072efd)) Recommended Action Ensure that the HTTP service and/or the agent on the machine myserver.mydomain.local are installed and running and that a firewall is not blocking HTTPS traffic. (Note - migrations between Hyper-V hosts managed by the VMM server work fine - my problem is just going from VS2005-Hyper-V hosts) I have no firewalls turned on on either of the servers, and no firewalls in the middle. I've looked all over for answers to this problem, and am getting nowhere. All the articles I find when searching are talking about either V2V or P2V - and i'm just trying to do a straight migrate VM. I've tried rebooting the boxes, changing the BITS SSL port number, restarting services, triple-checking firewalls, etc. Does anyone have any good suggestions as to how I can resolve this problem?

  • Crash dump analysis

    - by Ryan Ries
    I hope this isn't a stupid question, and if it is, then I want to at least get it over with so I don't feel so dumb in the future. Here we are, loading up a Windows crash dump with Windbg. Here are the first few lines of the debugger output: 0: kd> .dumpdebug ----- 64 bit Kernel Summary Dump Analysis DUMP_HEADER64: MajorVersion 0000000f MinorVersion 00001db1 ... The MinorVersion I mostly understand. It's hexadecimal and it translates to 7601 in decimal. Windows admins would already be able to tell from that that this must be either a Win7 x64 machine or a 2k8 R2 machine with SP1. But isn't 7601 the build number? It's supposed to be Major.Minor.Build/Revision... right? Also I don't understand the MajorVersion. It should be 6. This version of Windows is 6. But isn't 0000000f in hexadecimal 15 in decimal? The full version string of this version of Windows, when you launch the Command Prompt for instance, is 6.1.7601. If 7601 is the MinorVersion, then what is 1 and what is 6? And why does the crash dump say 0F?

  • Windows NT from vmware to kvm

    - by Luca Rossi
    I'm trying to convert a couple of old Windows NT virtual servers from vmware to KVM. I tried almost all guidelines and how to I found around the web but with no luck. I have the vmware virtual disk: Dlc1.vmdk partitioned image. I converted the vmdk into qcow2 image with the qemu utility and I tried to use it with kvm: kvm -hda test.qemu -vnc :1 -m 750 but I receive "error loading operating system" I also tried with raw partitions I can mount through losetup and kpartx. but nothing changed I also tried to create an brand new image file with: qemu-img create -f qcow2 test.qcow2 2G I partitioned the new image file and I copied the original partition 1 to the new partition 1 with dd: dd if=/dev/mapper/loop1p1 of=/dev/mapper/loop0p1 bs=128M no luck again I also tried with a single unpartitioned file: qemu-img create -f qcow2 test.qcow2 2G and I copied the partition 1 to the new image file: dd if=/dev/mapper/loop0p1 of=test.img bs=128M but when booting, I receive a black screen and the virtual machine hangs. The bootloader is loaded successfully, because I also tried with a GRUB live iso and I receive the same screens and errors. Note that grub sees the Windows setup and give me the boot choice. I have the suspect the problem is that the vmware machine is probably a scsi guest and in centos 6 (my system) scsi emulation is no longer supported. But in that case, where to change in Windows? I'm not so skilled with MS systems. Thank you for the help Luca Rossi

  • Firebird 2.5 Database Corrupt

    - by BrendanH
    We have an issue where a database hangs the server when: a backup is performed (Hangs on a specific table) selecting * or count(1) from a specific table or viewing data that is related to the table (FKs, etc) We could browse the table to a certain point (using IBExpert) however after about 2900 records the machine just spikes and hangs. Performing a gfix -m does not work, and the validation reports back Record level errors = 4 (no matter how many times we run gfix -m, -v, etc. The Firebird.log file reports back these types of messages: Relation has 91631 orphan backversions (9214273 in use) in table BINS (137) - {Which is apparently just a warning} Unable to complete network request to host "MHPLZA1". Error reading data from the connection. INET/inet_error: read errno = 10054 SERVER/process_packet: broken port, server exiting Shutting down the server with 1 active connection(s) to 1 database(s), 0 active service(s) - {If we leave the backup to run while hanging, it eventually logs this error message} The setup is: The table is question has about 7000 records. The Firebird version is 2.5 Classic Server x64 install. The OS is Windows Server 2008. This is a virtual machine (VMWare) running on a massive server. (Does anyone have issues with VMs and Firebird?). We have the same setup running fine on other servers (However they are not virtual machines). Is there anyway to pin point the issue and or the cause?

  • How do I get more information on a potential network freeloader?

    - by Dov
    I have a home network set up, complete with a relatively good password. I'm in Mac OS X 10.6 (Snow Leopard) and have been noticing, on occasion, a computer showing up in my Finder's Shared section, that is not one of my own (the "pe-xpjalle" box pictured below). He has a tendency to come and go. How can I figure out his MAC address or something, so I can block him? I checked my "Logs and Statistics" in the Airport Utility, and didn't see that computer under DHCP clients. I'd rather not change my password, since I have quite a few devices I'd have to update. Is there any other reason he's show up on my network besides having guessed my password? Update: I fixed the Dropbox URL above (how embarrassing, I'm new to Dropbox. Thanks for the heads up, Doug.) Update 2: I tried clicking on "Connect as..." just for the hell of it, and got the dialog below. Now I have even less an idea what's going on than before. I don't have Parallels of VMware running, just the following: Transmission, NetNewsWire, Mail, Things, Safari, iTunes, Photoshop, Pages, Yojimbo, Preferences, AppleScript Editor, Software Update, Airport Utility, and Terminal. I don't think any of those create a virtual network machine, right? And no VMware machine of mine has ever had a name resembling "pe-xpjalle". Update 3: I just changed my passwords on both my N- and G-only networks, and I'm still seeing this, so I highly doubt that it's someone who's figured out my password (twice now). I'm really stumped.

  • Error when trying to deploy Windows XP SP3 with WDS

    - by Nic Young
    I have created a WDS server running Windows Server 2008 R2. I have built my custom images of Windows 7 using WAIK and MDT 2010 that are installed on the server. I used this guide to help me through the process. The Windows 7 images that I have created capture and deploy properly. I am attempting to follow the same steps from the guide I linked to capture and deploy a Windows XP SP3 image. I am able to sysprep and capture the reference machine with no errors. I am then able to import the custom .wim that I just captured in to MDT 2010 with no issues either. However when I try to deploy this image to a test virtual machine I get the following error: Deployment Error: I have made sure that the .iso that I am importing the source files from originally to create the sysprep and capture sequence is indeed a Windows XP SP3 iso. When I first select a PE boot environment before I deploy I select the x86 PE boot image that I created originally when making this for my Windows 7 deployments. Could this be the issue? If so how do I make a boot image specific for Windows XP SP3 deployments? I have Googled around for this error and some places point to the deployment image not being able to find setup.exe and other important system files for installing the operating system. If so, how do I add these to the image? Any ideas?

  • ESXi Server with 12 physical cores maxed out with only 8 cores assigned in virtual machines

    - by Sam
    I have an ESXi 5 server running on a 2-processor, 12-core system with hyperthreading enabled. So: 12 physical cores, 24 logical ones. On this server are 4 Windows 7 VMs, each configured for 2 processors, each running VMware Tools. Looking at my stats in vSphere, my "core utilization" is constantly maxed out. Yes, these machines are working hard, but only 8 cores have been allocated. How is this possible? Should I look into reducing the processor count per machine as in this post: VMware ESX server? I checked to ensure that hardware virtualization is enabled in the BIOS of the machine (a DELL R410). I've also started reading up on configuration, but being a newbie there's a lot of material to catch up on. It also seems I should only bother with advanced settings and pools if I'm really pushing the load, and I don't think that I should be pushing it with so few VMs. I suspect that I have some basic, incorrect configuration setting, but it's also possible that I have some giant misconceptions about virtualization. Any pointers? EDIT: Given the responses I've gotten so far, it seems that this is a measurement problem and not a configuration problem, making this less critical. Perhaps the real question is: How does the core utilization of the server reach a higher percentage than all individual cores' core utilization, and given that this possibility makes the metric useless for overall server load, what is the best global metric for measuring CPU load on hyper-threaded systems?

  • Remotely managing Scheduled Tasks on another computer: Access Denied

    - by Eptin
    I need to remotely create new scheduled tasks from a Windows 7 computer in my company (which according to this Microsoft TechNet article I should be able to do. http://technet.microsoft.com/en-us/library/cc766266.aspx ) From within Task Scheduler, on the menu I click Action Connect to another Computer. I browse for the remote computer's name (I use Check Names to verify that the name is correct) and then I check 'Connect as another user' and enter \Administrator and the local admin password. Whenever I try this, I get the error message Task Scheduler: You do not have permission to access this computer Firewall isn't the problem I am able to use Remote Desktop with this username & password combo, so I would expect it to work when remotely managing as well. The remote computer has firewall exceptions for Remote Scheduled Tasks Management, Remote Service Management, and Remote Desktop among other things. Heck, I even tried turning off the firewall for that individual computer and it still didn't work. More details: I have administrative remote access to several other Windows 7 Enterprise computers, though I log in as the local Administrator (whose administrative rights are only recognized by that local machine, not by the domain). The computer I am managing from is on the domain, and also has administrative rights that are recognized on the domain. More experimentation: If I go the other way around and remote-desktop into the other machine and from there open task scheduler then 'connect to another computer', I am able to connect back to my main computer using the username & password that is recognized by an administrator on the domain, and successfully schedule a task on my main computer. So it's not a company firewall issue that's preventing anything from working. The only permissions requirement Microsoft talks about is "The user credentials that you use to connect to the remote computer must be a member of the Administrators group on the remote computer". I'm logging in as an Administrator on each of the local machines, so why doesn't it work?

  • How to configure Hyper-V failover cluster to live migrate when dynamic memory runs out?

    - by Matt Johnson
    Appologies in advance that this is not a direct programming question, but I have a feeling that the solution involves custom powershell scripts (maybe), so this is as good a place to ask as any. I maintain a website that has a large Hyper-V cluster for SQL Servers. We are using Windows 2008 R2 SP1, and the new "dynamic memory" feature. I've already ready reviewed the Best Practices Guide, and implemented it's suggested configuration. Everything works well, except that when SQL demand increases memory pressure to expand to more memory than is available on the physical machine, the memory status goes into the "Warning" state and stays there. I assume the hypervisor is using a swapfile on the host to fulfill the memory requirement, thus slowing the virtual machine down. When this happens, there are plenty of other nodes in the cluster that have available resources. I can live-migrate the virtual server over there and everything works, and the warnings go away. Now how can I automate this? I see no menu options in either Hyper-V or the Failover Cluster Manager for performing a migration or shutdown when dynamic memory goes into the warning state. Any ideas about how to script this, or monitor it and invoke the action directly, would be helpful. If the solution involves coding, powershell would be ideal, but I could envison this as a .Net Service that monitors for this state and kicks off the migration request. I just don't know what objects are involved in doing the monitoring or kicking off the live migration. Thanks in advance.

  • Probelms Intstalling Trac using apt-get Ubuntu Jaunty

    - by Ben Waine
    Hi, I'm having some issues getting apt to install trac correctly on my Ubuntu Jaunty Box. Using the command 'apt-get install trac' I get the following output: root@myserver:~# apt-get install trac Reading package lists... Done Building dependency tree Reading state information... Done Some packages could not be installed. This may mean that you have requested an impossible situation or if you are using the unstable distribution that some required packages have not yet been created or been moved out of Incoming. Since you only requested a single operation it is extremely likely that the package is simply not installable and a bug report against that package should be filed. The following information may help to resolve the situation: The following packages have unmet dependencies: trac: Depends: python-setuptools (> 0.5) but it is not installable Depends: python-pysqlite2 (>= 2.3.2) but it is not going to be installed Depends: python-subversion but it is not installable Depends: libjs-jquery but it is not installable Recommends: python-pygments (= 0.6) but it is not installable or enscript but it is not installable Recommends: python-tz but it is not installable E: Broken packages I have successfully used the command on my karmic kola desktop machine and am able to create new projects etc. I thought I might be able to solve the problem by installing all python related extensions. This produced a very similar output. I have Main, universe and multi-verse repositories enabled. Its a remote machine and I have no access to the gui. Hope someone can help, googleing failed to solve the issue or find a solution! Thanks, Ben

  • Win 7 running slowly with low CPU usage and memory

    - by guywhoneedsahand
    I have a relatively new (under 2 yrs old) windows 7 machine. It has 9GB of RAM, and an i7 core CPU (930 @ 2.8GHz w/ 8 CPUs). After about 8 months since a clean install, I noticed my computer was running slowly. I figure it was fragmentation etc, and I did a complete wipe & clean reinstall. However, my problems are somehow persisting. The computer is running painfully slowly (but in leaps and bounds - sometimes it will work fine for 3 hrs, then suddenly freeze up just from clicking the start button). The 'freezes' happen randomly - not during any especially intensive computing. I initially thought something might be eating through my CPU and/or Memory, but Task Manager indicates that neither the CPU or Memory spike. In fact, even during serious lag, CPU usage remains at less than 5% and Memory at ~ 1.5GB. It's beyond me why a fresh install on a powerful machine is performing so poorly... and it certainly is frustrating! What could be causing the poor performance, and what can I do to fix it?

  • What DBus signal is sent on system suspend?

    - by Paul Robinson
    Hello, I need to detect when a machine is going to sleep in Ubuntu 9.10 and Fedora 13. Both use UPower, so I've been looking on the "org.freedesktop.UPower" DBus bus for such signals. I've been listening for the "sleeping" signal on the UPower bus with the following command: dbus-monitor --system "type='signal',interface='org.freedesktop.UPower',member='Sleeping'" When I sleep the machine (either by closing the lid, selecting "shutdown - suspend" or sending a DBus message) I don't see a "sleeping" event. I notice that the "Sleeping" event is sent when the "org.freedesktop.UPower.AboutToSleep" method is invoked. I can do this manually by calling: dbus-send --print-reply --system --dest=org.freedesktop.UPower /org/freedesktop/UPower org.freedesktop.UPower.AboutToSleep And I notice the "sleeping" signal is fired. My understanding is that anything that sleeps the PC must send the "AboutToSleep" signal before hand. It doesn't seem like this is happening. I've tried these steps on both Fedora 13 and Ubuntu 9.10 and I see the same results. Can anyone explain what's happening or provide me with an alternative DBus signal to listen for? Many thanks, Paul

  • BitLocker with Windows DPAPI Encryption Key Management

    - by bigmac
    We have a need to enforce resting encryption on an iSCSI LUN that is accessible from within a Hyper-V virtual machine. We have implementing a working solution using BitLocker, using Windows Server 2012 on a Hyper-V Virtual Server which has iSCSI access to a LUN on our SAN. We were able to successfully do this by using the "floppy disk key storage" hack as defined in THIS POST. However, this method seems "hokey" to me. In my continued research, I found out that the Amazon Corporate IT team published a WHITEPAPER that outlined exactly what I was looking for in a more elegant solution, without the "floppy disk hack". On page 7 of this white paper, they state that they implemented Windows DPAPI Encryption Key Management to securely manage their BitLocker keys. This is exactly what I am looking to do, but they stated that they had to write a script to do this, yet they don't provide the script or even any pointers on how to create one. Does anyone have details on how to create a "script in conjunction with a service and a key-store file protected by the server’s machine account DPAPI key" (as they state in the whitepaper) to manage and auto-unlock BitLocker volumes? Any advice is appreciated.

  • port forwarding with VirtualBox

    - by Argh
    I have a virtualbox VM running ubuntu. The Ubuntu guest is running a web server which listens on port 3000 (http://127.0.0.1:3000) The host machine is windows vista. I have configured port forwarding using VBoxManage. If I query the config using VboxManage getextradata "MyMachine", I get Key: GUI/AutoresizeGuest, Value: on Key: GUI/Fullscreen, Value: off Key: GUI/LastCloseAction, Value: shutdown Key: GUI/LastWindowPostion, Value: 9,34,640,529,max Key: GUI/MiniToolBarAlignment, Value: bottom Key: GUI/MiniToolBarAutoHide, Value: off Key: GUI/SaveMountedAtRuntime, Value: yes Key: GUI/Seamless, Value: off Key: GUI/ShowMiniToolBar, Value: yes Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/GuestPort, Value: 3000 Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/HostPort, Value: 3000 Key: VBoxInternal/Devices/pcnet/0/LUN#0/Config/guesthttp/Protocol, Value: TCP This looks like it should work... However when I try to access the web server from the host machine (windows box) I dont get a response. I ran a netstat on the windows box and nothing appears to be listening on port 3000 which explains why forwrding isnt working. Note that I have already tested with my firewall switched off... The version of VirtualBox I am using is 3.1.4 Any ideas?

  • Linksys/Cisco Small Business SRW-Series (ie SRW248G4) - Overcoming the Limitations

    - by Warren P
    We just purchased a Cisco/Linksys SRW 248G4 switch to try it out. We have always had unmanaged switches before, and this is our first "somewhat managed" switch. So far the major limitations are: Only Internet Explorer 6 (manual says IE 5.5!) works for the web interface SSH exists but is not practically useable because the only key length that is supported is no longer even used by most modern SSH installs. (I get the error "RSA modulus too small" in openssh 4.x/5.x) This is with the latest firmware revision, I believe, although Cisco's website does not actually tell you what version you're downloading. All in all, I think, they must be trying to tell me that if I want a good-quality switch, I shouldn't buy these SRWs and should buy a Dell or an HP ProCurve, or save up my pennies, and buy a Catalyst. The question here, then, at long last: Has anyone gotten the web-browser to work via some IE 7 or IE 8 compatibility mode settings or used another browser (Opera? KDE/Safari/WebKit?) and spoofed IE6? Is there any way to get the SSH key length upgraded? I'm guessing a 0% chance of a yes on that last one. I found an XP machine, used telnet (via PuttyTel.exe) and IE6 to set this up, and I doubt we'll have to touch it again. Which is fine with us. But it would be nice if I could administer this thing from either (a) a linux box, or (b) my primary desktop which is windows 7. It looks like XPMode with IE6 on the virtual XP machine may be my only way to administer this type of switch via the web.

  • Can't remotely connect through SQL Server Management Studio

    - by FAtBalloon
    I have setup a SQL Server 2008 Express instance on a dedicated Windows 2008 Server hosted by 1and1.com. I cannot connect remotely to the server through management studio. I have taken the following steps below and am beyond any further ideas. I have researched the site and cannot figure anything else out so please forgive me if I missed something obvious, but I'm going crazy. Here's the lowdown. The SQL Server instance is running and works perfectly when working locally. In SQL Server Management Studio, I have checked the box "Allow Remote Connections to this Server" I have removed any external hardware firewall settings from the 1and1 admin panel Windows firewall on the server has been disabled, but just for kicks I added an inbound rule that allows for all connections on port 1433. In SQL Native Client configuration, TCP/IP is enabled. I also made sure the "IP1" with the server's IP address had a 0 for dynamic port, but I deleted it and added 1433 in the regular TCP Port field. I also set the "IPALL" TCP Port to 1433. In SQL Native Client configuration, SQL Server Browser is also running and I also tried adding an ALIAS in the I restarted SQL server after I set this value. Doing a "netstat -ano" on the server machine returns a TCP 0.0.0.0:1433 LISTENING UDP 0.0.0.0:1434 LISTENING I do a port scan from my local computer and it says that the port is FILTERED instead of LISTENING. I also tried to connect from Management studio on my local machine and it is throwing a connection error. Tried the following server names with SQL Server and Windows Authentication marked in the database security. ipaddress\SQLEXPRESS,1433 ipaddress\SQLEXPRESS ipaddress ipaddress,1433 tcp:ipaddress\SQLEXPRESS tcp:ipaddress\SQLEXPRESS,1433

  • Network monitoring tools with API features

    - by Kev
    We use ks-soft's Advanced Hostmonitor package to monitor around 2000 items on our network. We think it's great, the chap that supports it is fantastic, the product is fast, stable and mature but I feel as as we grow as a company it's beginning to show some friction points in the area of integration with our back office admin systems. One of the things we'd like to do is be able to add new tests to whatever monitoring tool we use via an API. For example, when orders for servers come from our retail interface, the server gets built automatically, and as part of the automated build process we'd like to automatically add new tests to the network monitoring systems. Hostmonitor has some support for this via a feature called HM Script but we're starting to encounter some speedbumps - we can't add new operators/users we can't define new "Action Profiles" - these are the actions to be taken when a test goes good or bad. What we love about hostmonitor though are the Action Profiles. For example if a Windows IIS box goes bad our action profile for a bad test does something like: Check host again (one time) Wait another 30 seconds then test again Try restart app pool on remote machine (up to two times) Send an email to ops about the restart failure Try restarting IIS on remote machine (up to four times) Page duty admin (up to 5 times - stops after duty admin ACKS alert) Page backup duty admin (5 times - stops after duty admin ACKS alert) I'm starting to look around at other network monitoring tools and I'm looking for: a comprehensive API to be able to add/remove/control tests/test "action profiles"/operators (not just plugins, we need control and admin interfaces) the ability to have quite detailed action/escalation profiles (and define these via an API) I've looked at Nagios and Icinga but Ican't seem to glean from their documentation whether we could have these features or not, or if we could, how much work would be involved to implement/customise. Can anyone provide any advice, guidance or experiences?

  • Windows Server 2008 R2 SP1 Drivers Missing Would Not Install?

    - by bleepzter
    I am building my dev machine with WS2008R2SP1. I consider Windows Server as the best development environment for C# since I tend to focus on server-centric (integration) applications. The desktop flavor of Windows (7) doesn't play nicely with things like Commerce Server or BizTalk... so I to like stick to the environment I develop for. Previously I used to develop inside of VM's but I've found that it is super inefficient and tends to take a toll on the laptops. (I've gone through two of them in 6 months). Problem is that I multiple devices that do not want to be recognized by Windows: My machine is Dell Precision M4500: Intel Core i7-Q740, 1TB HDD, 8GB RAM, Dell re-branded Broadcom DW1501 802x11n Half-Mini Card, Dell re-branded Broadcom DW375 Bluetooh Module, Intel 82577LM Gigabit Network connection NVidia Quadro FX1800 Graphics The devices in question are the Dell rebranded broadcom network and bluetooth adapters: Broadcom USH: USB\VID_0A5C&PID_5800&REV_0101&MI_00 USB\VID_0A5C&PID_5800&MI_00 DW375 Bluetooth Module USB\VID_413C&PID_8187&REV_0517 USB\VID_413C&PID_8187 When I ran the broadcom installers I get "Operating System not supported" which I think is a big oversight on Broadcom's part. Why check for system version string? UGHGHGH Moreover if I try to manually force the driver in windows... I get an error: Driver Management concluded the process to install driver FileRepository\btwampsecfl.inf_amd64_neutral_d8fc2b85d035ed47\btwampsecfl.inf for Device Instance ID USB\VID_0A5C&PID_5800&MI_00\7&66DE6C9&0&0000 with the following status: 0xe0000217.

  • HP Storageworks 448 tape drive input/output error with Ubuntu

  • In Windows 7, why can't I use perfmon against a remote server?

    - by SomeGuy
    I am on Windows 7 and trying to run perfmon against Windows 2003 and Windows 2008 servers. I am running into the same issue with all remote machines. When creating a data collector set, I specify a domain account that is in the administrators group on the remote machines (and "Performance Log Users" and "Performance Monitor Users" to be safe). On the "Available Counters" screen, When I type in a remote computer name, PerfMon locks up for a good 2-3 minutes before I can add any counters. I can then save the collector set. However, when I save it, the go/stop buttons are disabled if I click the set in the left panel, and missing if I click the Data collector set itself in the right panel. See the screens below. I can run data collector sets against my local machine with no problem. I am opening perfmon with my local account in both scenarios. I also have Remote Registry Service started on each remote machine. What is going on?

  • ZFS - destroying deduplicated zvol or data set stalls the server. How to recover?

    - by ewwhite
    I'm using Nexentastor on a secondary storage server running on an HP ProLiant DL180 G6 with 12 Midline (7200 RPM) SAS drives. The system has an E5620 CPU and 8GB RAM. There is no ZIL or L2ARC device. Last week, I created a 750GB sparse zvol with dedup and compression enabled to share via iSCSI to a VMWare ESX host. I then created a Windows 2008 file server image and copied ~300GB of user data to the VM. Once happy with the system, I moved the virtual machine to an NFS store on the same pool. Once up and running with my VMs on the NFS datastore, I decided to remove the original 750GB zvol. Doing so stalled the system. Access to the Nexenta web interface and NMC halted. I was eventually able to get to a raw shell. Most OS operations were fine, but the system was hanging on the zfs destroy -r vol1/filesystem command. Ugly. I found the following two OpenSolaris bugzilla entries and now understand that the machine will be bricked for an unknown period of time. It's been 14 hours, so I need a plan to be able to regain access to the server. http://bugs.opensolaris.org/bugdatabase/view_bug.do?bug_id=6924390 and http://bugs.opensolaris.org/bugdatabase/view_bug.do;jsessionid=593704962bcbe0743d82aa339988?bug_id=6924824 In the future, I'll probably take the advice given in one of the buzilla workarounds: Workaround Do not use dedupe, and do not attempt to destroy zvols that had dedupe enabled. Update: I had to force the system to power off. Upon reboot, the system stalls at Importing zfs filesystems. It's been that way for 2 hours now.

  • Routing multiple static IPs from ISP at the cable modem?

    - by Jakobud
    I'm taking over IT responsibilities for a previous IT guy. We have a 50mb cable modem connection from Comcast along with 5 static IP addresses: XXX.XXX.XXX.180 XXX.XXX.XXX.181 XXX.XXX.XXX.182 XXX.XXX.XXX.183 XXX.XXX.XXX.184 We are in the process of replacing our firewall machine. Currently the firewall box is the only thing connected to the cable modem. However the cable modem has multiple ethernet ports on it, similarly to a router. I have assembled a new firewall machine and its time to start testing and configuring it. So that means that I also need it plugged into the cable modem (remember it has multiple ethernet ports on it). So now with multiple computer plugged into the cable modem, how does the cable modem know where to route the traffic? If some request on the internet is made to XXX.XXX.XXX.181, which goes to our cable modem, how does the cable modem know which connected computer that traffic is supposed to be sent? Looking at the web interface for the cable modem, there doesn't seem to be anything special setup on it with regards to routing or NATing IP addresses. Is that because when there is only one computer connected to the modem, all traffic is sent to it by default? Now that I am going to (temporarily) have multiple computers plugged into the cable modem, do I need to specify routing or NAT rules on the modem itself? I am going to speak to Comcast about this next, but I figured I'd ask here first just so I can get a better grasp on how this type of thing generally plays out.

  • "A disk read error occurred" when booting XP disk image in VirtualBox

    - by intuited
    I'm trying to boot an XP installation cloned into VirtualBox from a real drive. I'm getting the message A disk read error occurred Press Ctrl+Alt+Del to restart whenever* I try to boot the machine. * This is not strictly true: with AMD-V enabled, the boot process appears to not make it this far and instead hangs at a black screen with cursor. I created the VirtualBox image from the original drive using the following method: $ sudo ddrescue -n /dev/sdd sdd.img logfile # completed without errors $ VBoxManage convertfromraw sdd.img disk.vdi The original disk (and the image) contain a single NTFS partition with XP installed on it. The owner of the drive indicates that it did boot okay the last time the system made it that far. The (Pentium 4) system has a broken (enormous) heat sink, so at some point it failed to boot because it would quickly overheat and shut down. If I boot the VM from a live cd, I am able to mount its /dev/sda1 without any problems. I ran ntfsfix and didn't have any luck. I've read through the instructions on doing this. I didn't really follow them. For example, I didn't run MergeIDE before imaging because the machine was not bootable. However, the symptom of that problem seems to be quite different. The emitted message is contained in the volume boot record of the XP partition, which leads me to suspect that this is a problem with the core operating system bootstrap procedure, and not related to anything in the registry. I don't have an XP boot CD.

  • Persistent static route stops working after VPN drops and reconnects

    - by user76157
    I've got a VPN between two networks, one home and one office (A and B). Their subnets are: (A) 192.168.1.0 and (B) 192.168.0.0 The two networks have identical ADSL routers. Unfortunately these can only do dial-out VPN. So I've got a Windows 2008 server on Network B acting as a VPN server (ServerB). Network A's router (RouterA) passes through Network B's router and connects via PPTP to ServerB. RouterA is assigned the static IP 192.168.0.40 on Network B. There's a persistent static route on ServerB telling it to use 0.40 for all requests to Network A's subnet, 192.168.1.0. (route -p add 192.168.1.0 mask 255.255.255.0 192.168.0.40). This enables ServerB to ping all machines on A (and those machines to ping ServerB). The VPN connection occasionally drops (I'm not sure why - it's set to remain always on and seems to drop randomly). This wouldn't be too much of a problem, as it reconnects automatically and quickly, except that when it does reconnect, the static route on ServerB no longer works. Route print (on ServerB) shows that the persistent static route still exists. However a tracert to a machine on Network A doesn't use the static route; it tries instead to use ServerB's default gateway (which is RouterB), and fails to find the machine. Deleting and re-adding the static route fixes the problem - a tracert uses the static route. At the moment, a batch file to delete and re-add the static route is scheduled to run every day. But this is clearly far from an ideal solution! I hope that's not too confusing. Any help would be very much appreciated.

  • ASUS P8B WS - Endless Reboots

    - by tuxGurl
    I am running a Intel XEON 1245 with 4GBx2 Kingston Memory ECC Unbuffered DDR3 on an ASUS P8B WS motherboard. BIOS Version 0904 x64. This system is a little over a month old. It is running Ubuntu 11.10. This evening I found the machine turned off. When I tried to restart it, it would POST and stop at the GRUB screen. When I selected Ubuntu and hit enter within 2-3 seconds the would shutdown and restart. If I stayed at the GRUB screen and did nothing the system would not cut out. I tried booting off a USB stick and again 2-3 seconds after selecting 'Try Ubuntu without Installing' the machine will cut power and reboot. Things I have tried so far: Resetting the BIOS using the on board jumper Resetting the BIOS settings to default Disconnecting all external hardware - except keyboard & monitor Booting with 1 stick of RAM - I tried different single sticks Ensured that onboard EPU and GPU boost switches are in the off position. I am running a Memtest86 right now and it has been running for 38+ minutes. This is not an OS problem or an overheating issue (I have a CoolerMaster HAF Case with 3 fans besides the CPU fan) I am at a loss as to what to try next. I think the BIOS is mis-configured somehow but I don't know what to look for.
