  • LUNs disappear after rebooting the ESX/ESXi host

    - by mariolos
    A single LUN among from a group disappeared. Neither the host nor the Vcenter can see it. Four virtual machines on the LUN now are unknown. The strange thing is the LUN is now available in the list when you try to ADD datastore from configuration == storage == Add Datastore But this cannot help me since i need the vms on the lun and i do not get options to add the lun without formating it to VMFS How can i get the lun back or atleast be able to copy the vms from it

  • UAC being turned off every time Windows 7 starts

    - by Mehper C. Palavuzlar
    I have strange problem on my HP laptop. This began to happen recently. Whenever I start my machine, Windows 7 Action Center displays the following warning: You need to restart your computer for UAC to be turned off. I never disable UAC, but obviously some process or virus (I'm not sure, only guessing) causes this. As soon as I get this warning, I head for the UAC settings, and re-enable UAC to dismiss this warning. This is a bothersome situation as I really don't know what causes the problem. I have run a full scan on the computer for any probable virus activity, but TrendMicro OfficeScan said that no viruses have been found. Malwarebytes' Anti-malware could not find any malicious items either. There are no other strange incidents on the machine. Everthing works fine except this bizarre incident. How can I learn what process is trying to turn off UAC? What way should I follow to overcome this problem?

  • Dell Latitude D510 Runs From Battery But Not AC Adapter

    - by Jason George
    I have a Dell Latitude D510 that went belly up around two years ago. It will run from the battery, however, the wall adapter will neither power the machine nor charge the battery. Once the battery is dead, the machine is dead. Since it died I've searched repeatedly for solutions. I've tried a new AC adapter and even removed and replaced the DC jack thinking one of the solder joints might be bad. Both to no avail. After two years of searching I finally found the answer today. Since it's such a simple fix and I had such a hard time finding it I wanted to post the info for others (as it is apparently a common issue with the D510). -----SOLUTION----- It seems this is commonly caused by a cracked solder joint at pin 1 on an inductor filter pair (FL2) near the power jack. Pins 1 and 4 are ground and pins 2 and 3 are power. There should be 20V from 1 to 2 and 3. Anything less indicates a cracked joint that is increasing resistance and dropping the supply voltage. Repair simply requires reflowing all four pins with a little added solder for security. Detailed instructions can be found here. Dell Latitude D510 solder problem

  • System Slow After Uprading Ubuntu

    - by Aragon N
    I have an Ubuntu network machine which has release of 10.04.1 LTS Lucid. On this system I have Apache, PostgreSQL and django. For some app. development I have to install PGP and php-curl. Due to being on network, I have exported a VMware machine to the Internet and firstly I have upgraded the system and then installed php5 packages on it. I don't know is it all about django or apache configuration. Maybe some Apache settings had changed. In this case in apache where I have to look at ? After all replacing it with its old place, I see that the new system query is slow according to another. Old system query time : 140 ms New system query time : 9.11 s I have checked /etc/network interface and it seems there is no problem. I have checked /etc/resolv.conf and it seems OK I have checked /etc/nsswitch.conf and only host section is different from old one which old system has hosts: files mdns4_minimal [NOTFOUND=return] dns mdns4 and then I have checked time host -t A services.myapp.com and I got real 0m0.355s user 0m0.010s sys 0m0.020s and I have checked apache2 HostnameLookups : find /etc/apache2/ -type f | xargs grep -i HostnameLookups It returned : /etc/apache2/apache2.conf:# HostnameLookups: Log the names of clients or just their IP addresses /etc/apache2/apache2.conf:HostnameLookups Off and now what can I have to check for boosting my system as before?

  • How to merge arbitrary snapshot into base vdi in Virtualbox

    - by jmathew
    I botched a transfer of a VM from one harddisk to the other. Now I'm left with the base vdi and a whole bunch of snapshots. My steps Copied old VM directory over to new HDD Deleted old VM and added new VM using using Machine-add and providing the old XML file Couldn't add base vdi file due to conflict so changed the UUID of base vdi with VBOXMANGE.EXE internalcommands sethduuid <path/to/vdi> Attempt to rollback to a snapshot, but it seems the VM is looking for the snapshots on the old HDD (which is formatted and gone) This is the error (networked is the name): Failed to restore the snapshot networked of the virtual machine lfs. Could not open the medium 'H:\vm\ft.vdi'. VD: error VERR_PATH_NOT_FOUND opening image file 'H:\vm\ft.vdi' (VERR_PATH_NOT_FOUND). Result Code: E_FAIL (0x80004005) Component: Medium Interface: IMedium {53f9cc0c-e0fd-40a5-a404-a7a5272082cd} The old HDD was drive H: the new one is drive N: How can I modify the snapshots/VM to look in N:\vm\ft.vdi for the base vdi? I've already set the default settings in VirtualBox in general (default vm/vm snapshot location). Or if not that how can I merge the old snap shot with the base vdi given that the only things that have changed is the base vdi's UUID?

  • How do VirtualBox Snapshots work?

    - by Edward Tanguay
    I've made three snapshots on VirtualBox virtual machine (winxp). I want to go back to Snapshot 2. If I click on "Snapshot 2" and click Start, it goes back to the current state. I can click on "Current State" and "revert to current snapshot" (unclear: what is the "current snapshot", since I have 3 snapshots), but after it is finished, I can't discern what it did exactly and when I click start, it returns to the current state. How do I go back to Snapshot 2?

  • Acer recovery disks not bootable?

    - by user13743
    We got a new Acer laptop with Vista installed at work. As it's getting ready to go out in the field, we wanted to do a burn-in test on it. We made the recovery DVDs before we ran the test. Part of the burn-in was bonnie++, which does a destructive read/write test of the hard drive. The machine passed with flying colors, but after trying to boot to the recovery DVD to being re-installing the system, the machine began to try PXE boot after a while. After doing some googling, it appears these 'recovery' disks expect a certain recovery partition to exist on the hard drive, and are in fact not bootable at all, and are useless in absence of the recovery partition. Is this the case, and is this "The Way Things Are" with all PC manufacturers and Windows Vista+ nowadays? How do I get my hands on actual bootable DVDs? I've emailed Acer support. I see an option on their site to purchase recovery disks, but I have the suspicion that these are the same non-bootable disks that I burned on the new system. Will Acer provide actual boot disks?

  • sub domains with /etc/hosts and apache for gitorious

    - by QLands
    I managed to have a local install of Gitorious. Now I need to finalize the apache integration using a virtual server but nothing seems to work. See for example my /etc/hosts file: 127.0.0.1 localhost 172.26.17.70 darkstar.ilri.org darkstar 172.26.17.70 git.darkstar.ilri.org My vhosts.conf has the following entries: # # Use name-based virtual hosting. # NameVirtualHost *:80 <VirtualHost *:80> <Directory /srv/httpd/htdocs> Options Indexes FollowSymLinks ExecCGI AllowOverride None Order allow,deny Allow from all </Directory> ServerName darkstar.ilri.org DocumentRoot /srv/httpd/htdocs ErrorLog /var/log/httpd/error_log AddHandler cgi-script .cgi </VirtualHost> <VirtualHost *:80> <Directory /srv/httpd/git.darkstar.ilri.org/gitorious/public> Options FollowSymLinks ExecCGI AllowOverride None Order allow,deny Allow from All </Directory> AddHandler cgi-script .cgi DocumentRoot /srv/httpd/git.darkstar.ilri.org/gitorious/public ServerName git.darkstar.ilri.org ErrorLog /var/www/git.darkstar.ilri.org/log/error.log CustomLog /var/www/git.darkstar.ilri.org/log/access.log combined AddOutputFilterByType DEFLATE text/html text/plain text/xml text/javascript text/css application/x-javascript BrowserMatch ^Mozilla/4 gzip-only-text/html BrowserMatch ^Mozilla/4\.0[678] no-gzip BrowserMatch \bMSIE !no-gzip !gzip-only-text/html <FilesMatch "\.(ico|pdf|flv|jpg|jpeg|png|gif|js|css|swf)$"> ExpiresActive On ExpiresDefault "access plus 1 year" </FilesMatch> FileETag None RewriteEngine On RewriteCond %{DOCUMENT_ROOT}/system/maintenance.html -f RewriteCond %{SCRIPT_FILENAME} !maintenance.html RewriteRule ^.*$ /system/maintenance.html [L] </VirtualHost> Now, when I go with Firefox to darkstar.ilri.org it shows the default Apache screen: "It works!". but when I go to git.darkstar.ilri.org it waits for few seconds then falls to darkstar.ilri.org and the default apache page. No error is reported. If I run httpd -S I get: VirtualHost configuration: wildcard NameVirtualHosts and _default_ servers: *:80 is a NameVirtualHost default server darkstar.ilri.org (/etc/httpd/extra/httpd-vhosts.conf:21) port 80 namevhost darkstar.ilri.org (/etc/httpd/extra/httpd-vhosts.conf:21) port 80 namevhost git.darkstar.ilri.org (/etc/httpd/extra/httpd-vhosts.conf:37) Syntax OK The funny thing is that if I configure gotirious in a host called gitrepository, add 127.0.0.1 gitrepository and go with Firefox to gitrepository.. Gitorious works... But why not with git.darkstar.ilri.org? Many thanks in advance.

  • Exchange 2007 - Mailbox Database Recovery

    - by Phrontiste
    Exchange 2007 edb Can we restore Exchange edb (First storage group\mailbox database.edb) to another exchange server ? Do I just copy the edb to the new exchange server and delete the first storage group\mailbox database.edb and replace it with this one ? How can I get all the mailboxes from that (old) mailbox database.edb ? I had a exchange 2007 server with 10 mailboxes, I have installed exchange on another machine and was thinking if I can do the above ? or is there any way I can get all the mailboxes from that edb (old mailbox database) and import them into the new one. I have deleted the old exchange install I had (these are test machines) What are the steps required to get the DB working on the new machine ? Also, I am confused about the recovery storage group ? I can mount a mailbox database in recovery storage group, but when I try to get mailbox out of it, it won't match any thing ? can someone please assist in understanding RSG and how to restore the OLD mailbox database. thanks and regards Phrontiste

  • Problem with Outlook 2010 (SMTP AUTH LOGIN)

    - by Filipe YaBa Polido
    I have to connect one customer Outlook 2010 to a remote server on which I have either no right, neither way to talk to the sysadmin. This is the thing, after installing and reviewing the logs on Wireshark: Outlook Express: HELO machine AUTH LOGIN username base64 encoded password base64 encoded mails go through. Outlook 2010: HELO machine AUTH DIGEST-MD5 response from server Outlook sends just a * AUTH LOGIN password base64 encoded So... I can send mails in the same domain, but can't send outside, it gives me a relay denied message. My point is... Why the h**l Outlook 2010 doesn't send the username AND the password?! It can never login the right way :| With other versions of Outlook it works fine, and with OE works great, it auths and allows to send mail to a different domain. I've googled and nothing worked. I'm pretty sure that I'm not alone with this one. My last resort will be to configure a local proxy/server that relays to the original one :| Any help would be appreciated. Sorry my bad english as is not my natural language. Thanks.

  • Windows Home 7 and virtualization

    - by progtick
    so apparently, you can't use VirtualBox etc with Windows Home 7. because you would be using two licenses instead of one. So other users that tried virtualization with Windows Home Premium 7, did you just end up using another OS like Ubuntu etc? Did you find a workaround for using Windows? When I say virtualization, I mean virtual machine of sort - where dangerous websites can be visited, nasty applications can be tried etc.

  • External Storage for 2TB of backups and 4TB of data RAID level? HW vs Software?

    - by Jerry Mayers
    I have a Mac Mini set up as a media center/file server. Currently I just have a hodgepodge mess of external drives for storage. I'm maxed out, and I have some new laptops on the way with much larger drives and I need to work out a good storage solution for backing them up, as well as storing media on the server. I need around 2 TB of storage for the time machine backups from my various systems and around 2 TB more for media. I would like to build this to handle around 6 TB total so I have some growing room. Since I'm using a Mac Mini as the server I need to use external enclosure(s) that support USB 2 or Firewire 800 (preferred) or gigabit Ethernet. Performance of the system isn't a huge concern since the majority of the access from other computers is done over 802.11N. I plan on using 2TB drives, for the final version, but initially I'll try and use my existing 2 (1TB) drives + some new 2TB drives, and swap the 1TB ones out as I fill up. As to the actual questions: Should I use hardware RAID in some enclosure? Because if the enclosure dies I have to find an identical one to get to my data right? Wouldn't a software RAID be better as I can use any method of connecting the drives to the system? Remember OS X server is my OS. What if I had to reinstall OS X, can I restore the software RAID easily? What RAID version should I use? For the 2TB used for the time machine disk I don't see why I need RAID here, just a single 2TB drive since its already the backup, but for the remaining 4TB it would be the only copy of the data so I should build some redundancy. I had a RAID 5 setup using a cheep RAID PCI card years ago running RAID 5 in a 2 TB array and when a drive died it wanted 48 hours to rebuild. Is this crazy slow for a setup of this size or is this to be expected? Any suggestions as to drive enclosures?

  • Can you create ACLs with open vSwitch on XenServer 5.6FP1 without using the DVS appliance?

    - by bwizzy
    I have a pool of XenServer hosts running the Free version of XenServer 5.6 FP1. I was wondering if I change the network backend to use Open vSwitch if I can specify ACLs on individual network VIFs without needing to use the DVS appliance (distributed virtual switch) which requires an Advanced License or higher. Basically I'm looking for a way to isolate VMs on my network so that if a user had root access on the command line they couldn't access other servers they should not be able to (without using a VLAN).

  • Why can't I see all of the client certificates available when I visit my web site locally on Windows 7 IIS 7?

    - by Jay
    My team has recently moved to Windows 7 for our developer machines. We are attempting to configure IIS for application testing. Our application requires SSL and client certificates in order to authenticate. What I've done: I have configured IIS to require SSL and require (and tried accept) certificates under SSL Settings. I have created the https binding and set it to the proper server certificate. I've installed all the root and intermediate chain certificates for the soft certificates properly in current user and local machine stores. The problem When I browse to the web site, the SSL connection is established and I am prompted to choose a certificate. The issue is that the certificate is one that is created by my company that would be invalid for use in the application. I am not given the soft certificates that I have installed using MMC and IE. We are able to utilize the soft certs from our development machines to our Windows 2008 servers that host the application. What I did: I have attempted to copy the Root CA to every folder location for the Current User and Location Machine account stores that the company certificate's root is in. My questions: Could I be mishandling the certs anywhere else? Could there be a local/group policy that could be blocking the other certs from use? What (if anything) should have to be done differently on Windows 7 from 2008 in regards to IIS? Thanks for your help.

  • Toshiba Satellite P755D USB 3.0 Drivers Missing - Windows 7 Professional

    - by nicorellius
    I bought a Toshiba Satellite P755D recently and installed Windows 7 Professional on the machine. It runs great. But I noticed the exclamation point in the yellow triangle icon in the Device Manager next to the Universal Serial Buss (USB) Controller (I'm assuming this is the USB 3.0 controller because mine doesn't recognize devices). Normally, when this kind of thing happens I go to the manufacturer's website and download appropriate drivers and call it a day. But not this time... I browsed to my model and found no driver for the USB 3.0 controller. I tried other HW and Utility drivers, thinking they would be bundled. No luck. I tried looking up the motherboard in my machine. Generic name, no luck. I then called Toshiba technical support and they tried basic troubleshooting, eg, uninstall device, reboot, for auto-installation; no luck. I popped the Windows 7 disk back in and tried to get information that way, no luck. Finally, the technical support guy said he would look into the engineer's system to see if there was a specific driver available and that's where I'm at. The technician told me that these USB 3.0 drivers come within the native driver pack in windows but that doesn't seem to be the case. Any ideas? EDIT - See attached screen shots.

  • What filesystem for shared (read/write) PC/Mac external drive?

    - by webworm
    Is there a recommended filesystem to use when sharing an external drive between the Mac and PC? I understand there are options for Macs to read/write NTFS filesystems and also for PCs to read/write HFS+ filesystems. Is there a preferred filesystem or perhaps a different filesystem that both Mac and PC and read/write? I know I could use FAT32 but some of the files I use are larger than 4 GB (i.e. Virtual Machine images)

  • Linux ubuntu wubi

    - by Jamaica Bob
    I would like to install linux ubuntu next to my primary windows 7 OS. I found that wubi ubuntu installer which helps you with simple installation/uninstallation of ubuntu. But the wiki says that wubi uses a virtual disk. Is that similar to virtually running the OS? I really dont want my primary system to slow down because of that. Should i rather go with the classical dual boot? If WUBI, whats the recommended install size? Thanks

  • Old scheduled task still being started, but can't find it.

    - by JvO
    System: Windows XP Home Summary: Some scheduled task is still being started by Windows, but I can't find it, nor determine where its configuration has been stored. This is turning into a mystery for me... I set up a Windows XP Home machine to run a task at 7:00 AM, using the Task manager. This was a clean install, no users defined, so you got straight to the desktop after starting the machine. The filesystem uses NTFS. Later on, I needed to introduce users, so I created one (named Sam) with administrator privileges. After this I noticed that the scheduled task failed, most likely due to privilege errors (i.e. can't write to a network drive). So I want to delete the old task, and add it again with the correct user credentials. However.... I can't find the old task!! I know it is still being executed at 7:00 AM, but there's no mention anywhere on the system of this task. I've looked in c:\windows\tasks for .job files, but there's only the "MP Scheduled Scan.job" from Security Essentials. I've searched the whole disk for mention of the batch file that is being run, but can't find it. So why is this old task still running, and more importantly, why can't I find it? Would it have something to do with introducing users on XP?

  • Best way to partition 1TB (Linux&Windows7)

    - by Simon
    Any intelligent way to partition 1TB and be prepared for resizing/adding/deleting partitions? I was thinking about LVM, but as far as i remember, Windows7 can't be installed on logical volume right? For now my plan is: - ~150GB for Windows7 and other stuff (VisualStudio..., maybe I'll split it 100/50 or something like that) - simple NTFS - 850GB = LVM - disk for linux (Ubuntu) and other stuff virtual machines etc. I'm mostly interested in how and what tools should I use to get easy in maintain partitions for both systems.
