• Backup data from RAID 1 disk out of its server

  - by Doomsday

  I'm facing with a pretty easy problem in my opinion. I've extracted a working disk from a RAID1 and I'm looking to copy only data (FS and RAID configuration doesn't matter) into another location (another FS). My problem is I'm not able to mount properly this disk into another linux. I've first looked the partition table : # fdisk -l /dev/sdc Disk /dev/sdc: 640.1 GB, 640135028736 bytes 255 heads, 63 sectors/track, 77825 cylinders, total 1250263728 sectors Units = sectors of 1 * 512 = 512 bytes Sector size (logical/physical): 512 bytes / 512 bytes I/O size (minimum/optimal): 512 bytes / 512 bytes Disk identifier: 0x00000000 Device Boot Start End Blocks Id System /dev/sdc1 63 1249535699 624767818+ fd Linux raid autodetect /dev/sdc2 1249535700 1250017649 240975 fd Linux raid autodetect /dev/sdc3 1250017650 1250258624 120487+ 82 Linux swap / Solaris I've understood I should use dmraid tools.

Anyone has a clue ?

• Defragging Host OS of VMWare

  - by JackLocke

  Hi All, I want to ask something that has been puzzling me from last few days. I will try to explain my problem as clear as I can ... I have VMWare Workstation installed in my machine. And I use one separate 100Gb drive which stores all of my virtual machines, nothing else. Now, last week I was playing with a De-fragmentation tool called "Smart Defrag" which showed me in its analysis report that my drive where I am currently storing all of my Virtual Machines has more than 80% of fragmentation !!! Now my question is ... What will be the effect on my Guest / VM machine performance if I defrag my Host machine ... I mean this Host machine is essentially storing those virtual machines, but still dont have any direct access to what ever is stored in those machines ... so defraging the host should not cause any problem. But before proceeding, I want to hear from other people who may have met same problem. I will really appreciate any help ... BTW, I am using Windows 7 as Host and the guest machines I am using are Windows 2008 & 2003 & Ubuntu 10.04 THanks, Jack

• Formula-based Excel page headers

  - by Jake Krohn

  I'm using the "Rows to repeat at top" function in Excel's "Page Setup" dialog to ensure that a multi-row header block appears on every printed page of my worksheet. However, I'd like to be able to change certain bits of the header based on the content of the current page. I would simply like to display the value of one cell in the first row that is printed on the page. If this is my header: Section: xx And the data looks like this (columns are Section and Name): 1 Foo 1 Bar 2 Baz I want the "xx" in the header to be "1". If, further down on the next page, the value in the Section column is "3", I want that printed in the header of the next page. I originally thought that using the "OFFSET" function might help, e.g. ="Section: "&OFFSET(A2, 1, 0) But it only shows the offset from the original placement of the header, thus only working on page 1. The end document is a PDF, so right now I'm able to go back in with the "TouchUp Text Tool" in Acrobat and add the numbers page by page. But it gets to be a tedious process with 70+ page reports. Anyone have any better ideas that don't require me mucking up the original Excel document with inserted headers every N lines? This is Excel 2008 for Mac, if it makes a difference.

• Is there a command to change primary group for a new user in Cygwin?

  - by Rob Gilliam

  Is there a way to set a (new) user's primary group in Cygwin's /etc/passwd file without hand-editing the file? I have a local group set up for members of the Dev Team on a Windows Server 2008 R2 box so that we can all modify a particular group files, but the regular users can only read them. As some of the work we do uses scripts that rely on Cygwin tools, this group is also in the /etc/group file. When I need to add a new user to the "Dev Team" group, I add them in Server Manager, and then use mkpasswd to add that user to Cygwin's /etc/passwd file. Unfortunately, they get the regular Domain Users group assigned as their primary group and I then have to go in and edit the passwd file to change the group. I now need to write some instructions for someone else who is not au fait with UNIX/Linux/Cygwin so that they can set up new Dev Team users and obviously "hand editing" /etc/passwd is a recipe for disaster if you don't know what you're doing. So, is there a way of getting mkpasswd to set a different primary group, or another tool like Linux's usermod which can be used for the purpose of changing the group in a more controlled manner?

• Moving a site from IIs6 to IIS7.5

  - by Sukotto

  I need to move a site off of IIS6 (Win Server 2003) and onto IIS7.5 (Win Server 2008) as soon as possible. Preferably tomorrow. The site itself is a delightful mix of classic asp (vbscript) and one-off asp.net (C#) applications (each asp.net app is in its own virtual dir and has a self-contained web.config). In case it's relevant, this is a sort of research site made up of 40 or 50 unconnected microsites. Each microsite is typically a simple form allowing a user to submit a form, which then runs a Stored Proc on a sqlserver db and displays a chart and/or table of the results. There is very little security to worry about. The database connection info is in a central file (in the case of the classic asp) or app's individual web.config (lots of duplication there) To add a little spice to the exercise... I have no idea how to admin IIS The company no longer employs the sysadmin or the guys who set this thing up. (They're not going to employ me much longer either but my sense of professional pride does not permit me to just walk away from this task). The servers are on mutually firewalled networks and I have to perform a convoluted, multi-step process to copy anything from one to the other. Would someone please point me to a crash-course tutorial for accomplishing the above? I have: a complete copy of the site's filesystem on the new box installed the 3rd party charting tool on the new system a config.xml file from the "all tasks - save configuration to a file" right click menu. There doesn't seem to be a way to import it on the new system however. The newer IIS manager has a completely different UI and I'm totally lost. Please help.

• System Center 2012 VMM UI is very slow

  - by Grant

  I've recently setup system center 2012 a new server 2008 r2 server which I'm using for virtual machines. Everything seems to be working fine, and the virtual machines are nice and fast. But the Virtual Machine Manager interface is always excruciatingly slow. Sometimes taking up to 15 seconds moving between screens. It's very frustrating trying to use it when a task that just involves a couple clicks ends up taking several minutes. Pages that have a lot of form fields seem to take the longest to load - such as the page to change hardware settings of a virtual machine. Is this just normal performance for VMM? If not, where can I look to find what is slowing it down. Nothing else on the system seems to suffer. I can load and use Hyper-V manager with no noticable slowness. Even programs like event viewer that are usually rather slow seem to load fairly fast. Only the system center programs seem slow. Server is a Dell R710, 2x16 core opteron 6274 processors, 96GB RAM. OS drive is 2x500GB 7.2k RPM SAS drives in RAID1 (opted for the less expensive 7.2k drives since pretty much everything is stored on the SAN). Am I just being impatient? Does anyone else use VMM 2012 and find it slow?

• Symantec Backup Exec 12 Tape Alert.

  - by Adam

  Every day, I run 5 backups using 6 tapes. Each day, when I run the inventory, I get a tape alert Error. This occurs every day, on the same job. The error is: Job 'Inventory Daily ********' has reported Multiple Tape Alerts on server '******' Please refer to job log *****.xml for more information. When i look at the Job log, the Utility Job Information says: The device has reported the following TapeAlert diagnostic information Information- The library has been manually turned offline and is unavailable for use.

• Sharepoint AD imported users are becomming sporadically corrupted, causing us to have to create a ne

  - by TrevJen

  Sharepoint 2007 MOSS with AD imported users. All servers are 2008. I have around 50 users, over the past 2 months, I have had a handful of the users suddenly unable to login to Sharepoint. When they login, they either get a blank screen or they are repropmted. These users are using accounts that have been used for many months, sometimes the problem originates with a password change. In all cases, the users account works on every other Active Directory authenticated resource (domain, exchange, LDAP). In the most recent case, last night I was forced deleted a user ("John smith") because of corruption. The orifinal account name was jsmith. I deleted him from active directory, then deleted him from the profile list in Sharepoint Shared Services. I could not find a way to delete him from the Sharepoint user list, but I reran the import after recreating his account (renamed it too just to be sure to "smithj"). At first, this did not wor, the user could still access all other resources but Sharepoint. then, some 30 minutes later it inexplicably started working. This morning, the user changed passwords, which immediatly broke the login on Sharepoint again. I am at a loss on how to troubleshoot this.

• Is Hyper-V server suitable as a desktop testbench?

  - by Thomas.Winsnes

  At the moment we are running a test bench with several desktop computers, that are reimaged every time we need to test on a different operation system. Also because different versions of our software is tested on each image, we have to install our software every time we want to test it. The problem we have had with going with a virtualization technology is that our software is depending on directx/opengl and 3D acceleration, and this has not been something that virtual machines have excelled at. With the release of SP1 for Windows 7 and Server 2008 R2 Hyper-V has gotten better 3D acceleration support, so we are looking into virtualizing our testbench using this. Our test scenario would most likely be something close to this: 1. Remote into the hyper-V server and load the test VM needed for the current tests 2. Remote into the VM and install the new version of the software 3. Run the tests It would be nice, but not essential, if our support team could remote into the VMs to match the users OS+software combination when doing support. Does anyone have any experience with this kind of settup with hyper-v?

• Licensing SQL Server 2012 Reporting Services w/ SharePoint 2010

  - by Evan M.

  Here's my situation: I have 1 VM that is running SharePoint 2010 SP1. I have a different physical server that is running SQL Server 2008 R2 that hosts all the configuration and content database for SharePoint. Now, we want to start providing BI capabilities to our users with SharePoint and SQL Server. With it's new features, 2012 is the obvious way to go. To support this, I'm looking to build a new VM that will have SQL Server 2012 installed w/ Analysis services and SSIS, which will be the platform that gets our data from our Oracle databases, puts it in a warehouse hosted by the SQL 2012 instance, and is put into cubes. What's getting me about the platform is licensing for Reporting Services and PowerPivot. My plan was to install SSRS and PowerPivot on the current SharePoint server. But my understanding of the licensing means that instead of the new SQL server being licensed, I'd have to license both new server, and the SharePoint server. Conversely, I could install SharePoint onto the SQL server, and only have to get a second SP license, but then I'd have the added complexity of deploying a separated application server, and combines my data and application servers. Is my licensing understanding correct, or can I have SSRS and PowerPivot installed separately without incurring additional licensing costs?

• Handling emails on a web server - Making sure the FQDN is set correctly based on the website sending the email

  - by webnoob

  I have a Windows 2008 Web Edition server hosting multiple websites using IIS 7.5. At the moment, all the emails are sent via the IIS6 SMTP service. The FQDN of the SMTP service is set to the computer name at the moment which isn't correct as it doesn't resolve to a valid DNS entry and is not RFC compliant. Some questions: Is there any way I can change the FQDN of the SMTP service based on the site sending the email? Would it be Ok to just setup mailserver.mydomain.com and use that as the FQDN for all the sites on multiple domains. Should I be using some other mail server software to handle this better? The reason I am asking is lots of emails are hitting spam folders because the settings are incorrect. I have access to the code that is running the websites so if something needs to be done there then that shouldn't be a problem. The sites are written using ASP.NET 2.0. EDIT: I have just found an option to create an SMTP virtual service. Would this be the way forward? Create a virtual server for each site? Thanks.

• vSphere Promiscuous mode only receiving packets one way from network switch

  - by steve.lippert

  We have two network switches, a POE switch (SwitchA) to power our phones / users computers and a non-POE switch (SwitchB for the rest network.) Each switch is setup to do port mirroring to support our VoIP recording system. SwitchA does port mirroring on specific ports if we need to record a user. SwitchB mirrors one port to monitor our work at home users (Internet comes in from managed router, to switch, back out to our firewall.) These two port mirroring setups feed into one vmware vSphere 4.1 server, it has four total physical cards. The other two NICs feed into an unmanaged switch for connecting to the rest of the network. Once into the vSphere server all network ports go into a vSwitch, and then one of the servers (Windows 2008 R2) sniffs them out and does its thing. Everything is working fine and dandy from SwitchB. But on SwitchA we only receive one side of the VoIP packets (going out to the phone, nothing coming in from the phone). Troubleshooting steps I have taken so far: I hooked up my laptop to the monitor port on SwitchB and I see both sides of the packets. I swapped which network interface is plugged into the monitor port on SwitchA. Because everything feeds into one vSwitch / vNetwork and both sides of the conversation arrive just fine from SwitchB I believe everything is configured correctly on the vSphere server/guest. What could be causing one way packets to arrive on my guest machine from only one interface, but not the other? Could a bad cable be causing the problems from SwitchB?

• Incredble low disk performance on HP DL385 G7

  - by 3molo

  Hi, As a test of the Opteron processor family, I bought a HP DL385 G7 6128 with HP Smart Array P410i Controller - no memory. The machine has 20GB ram 2x146GB 15k rpm SAS + 2x250GB SATA2, both in Raid 1 configurations. I run Vmware ESXi 4.1. Problem: Even with one virtual machine only, tried Linux 2.6/Windows server 2008/Windows 7, the VMs' feel really sluggish. With windows 7, the vmware converter installation even timed out. Tried both SATA and SAS disks and SATA disks are nearly unsusable, while SAS disks feels extremely slow.I can't see a lot of disk activity in the infrastructure client, but I haven't been looking for causes or even tried diagnostics because I have a feeling that it's either because of the cheap raid controller - or simply because of the lack of memory for it. Despite the problems, I continued and installed a virtual machine that serves a key function, so it's not easy to take it down and run diagnostics. Would very much like to know what you guys have to say of it, is it more likely to be a problem with the controller/disks or is it low performance because of budget components? Thanks in advance,

• DPM server 2010 Attach agent error : administrator privileges missing?

  - by Michael

  I’m hoping you would be able to help me out with this little problem I’m having. I installed DPM 2010 in our test environment to test backups on Exchange 2010 servers. The environment includes : 1xDC 2x Exchange Server 2010 1x DPM 2010 server All of these are running on Microsoft server 2008 R2 Virtual machines. The host machines are using Hyper-v. So the problem goes like this : 1- I tried to install the agents from the DPM server GUI, which failed saying I didn’t have the correct permissions. 2- So then I tried the manual installation using the commands from : the Microsoft site http://technet.microsoft.com/en-us/library/bb870935.aspx 3- The agent installation worked but when I get to attaching the agents to the DPM server it still gives me the error saying that the specified account does not have administrator rights. 4- I tried the Domain admin, users who are domain admin + local admin, single local admins. 5- I have turned off the windows firewall and made sure all the services are running. So now I’m out of ideas and really need help, the agent attach to the DPM server is the last thing that is holding me back from deploying everything to the production site. Any help would be really appreciated.

• OS X won't boot up unless I hold down option key

  - by Gazzer

  I have a strange issue on an early 2008 Mac Pro running OS 10.6: if I restart the computer it restarts normally if I shutdown and boot, it stops at the grey screen just before the boot process if I shutdown and boot but hold down the option key, I can select the boot disk and all is good. I've just cloned the disk, and the same thing happens. The disk is a SAMSUNG HD154UI The disk is partitioned (the second partition holds a clone of the Snow Leopard Install disk) One weird thing on the original disk was one of the partitions said 'EFI Boot' in a non-aliased font rather than the name of the disk when the disks are listed upon holding down option. Solution: it seems that there was a problem with the disk. Part of the difficulty in finding the solution was that you need to remove the disk from the computer completely. For example, a good disk in Bay 3, wouldn't boot up if the bad disk was in Bay 2. So for ages I thought the problem was hardware related in Bay 3. So if you think you have a dodgy disk remove it totally if you are testing the hardware with a 'clean' disk. Cleaning the PRAM helped to get the new disk to work too.

• Looking for some IIS redirect help/ideas

  - by CoreyT

  Right now we have a site with a LOT of static asp pages such as, www.site.com/123.asp. This is due to how our current site's CMS builds it's pages by default. I don't have an exact count but we have roughly 6000 asp files in the site right now. We are in the middle of a redesign and restructuring of the site, and are looking to migrate to SEO friendly URLs. The problem we're having right now is what do we do to redirect the old pages to the new friendly URLs? I know how to do redirects that is not the issue here. The problems I am coming up with right now are listed below. 1 - Is there a limit to the number of redirects in IIS? 2 - Would having even a few thousand redirects affect IIS performance? 3 - My understanding is that we would not be passing along page rank to the new URLs, is that true? (not a major question I can ask on more SEO forums if nobody here is sure) 4 - Would using something like the IIS URL Rewrite 2 module for IIS 7 help us out? Or would I still need to define several thousand unique redirects in it? Our server right now is running Server 2003, however in the redesign I would be open to migrating to Server 2008 R2 if there is a good case for it (i.e. the URL Rewrite module). Thanks for any guidance or help. I have been looking for a good way to do this for a while now and keep coming up with things that sound problematic and bad (such as having 6000 redirects).

• Optimizing Apache for large file serving

Can switching to Linux help me achieve better CPU usage?

• Upgraded users to Win7. Now getting "path not found" when saving files or opening attachments

  - by Matt Penner

  We have a Server 2008 AD environment with about 5k users. We just rolled out Windows 7 SP1 (were XP) with great success. However, about once a day we get a few calls that a user opens a file from their Documents (the folder is on the server and redirected), edits it and attempts to save but Win7 reports that the path is not found either because it doesn't exist or no permissions. The only way to fix it is to delete the profile. In addition we get about the same number but different users saying that they cannot open attachments from Outlook 2010 due to no permission. We have to edit the temp Outlook storage path in the registry to fix it (or delete the profile). I think the two issues may be related. What scares us is that we rolled out 1 month ago and had no calls of this nature until about 2 weeks ago. It started off as one or two but seems to be growing. Any ideas? We're going to open a Microsoft ticket but I wanted to seenif anyone else has run into this. Thanks!

• Inbox not updating in Exchange 2010, all users affected

  - by TuxMeister

  I'm battling against this darn issue this morning. We have the following setup: Big Hyper-V machine hosting the servers as VM's VM for CAS: WEB.XXX.local VM for Mailbox: EXC.XXX.local Servers are running Server 2008 R2 with Exchange 2010 SP1 Clients are all running Windows 7 Pro x64 with Outlook 2010 x64 The problem we're having is that nobody is able to see any emails received today (16th of October), but they are able to send externally. When I reply back to the email received externally, I don't get an NDR, yet the user cannot see my email. This is what I found and tried thus far: If we create a subfolder in Outlook 2010 and move any email from the inbox into that folder, changes will be immediately reflected in OWA We've been sending test emails to other users internaly and external email addresses and the sent items folder contains all those tests, synced properly to OWA as well Have tried crating a new profile, new emails are still missing Tried disabling Cache Mode, still no luck Also disabled "Download shared folders", still no luck Tried to setup a brand new Exchange mailbox and configured it on a VM that never had Outlook on it, still the same issue Tried restarting Exchange services on both CAS and Mailbox servers, no luck Tried rebooting both CAS and Mailbox servers, still no luck Performed a Mailbox Discovery on my admin account, emails from today are being found in the Discovery results, so the stuff is there, just not updating the user inboxes Any idea about what this hellish thing can be? I've done everything I can think of and also everything I could find out there. Let me know if you need any more details and thanks for reading this!

• What Windows service binds a NIC to the network?

  - by Bigbio2002

  I have a server that takes several minutes for the NIC to bind itself to the network upon startup (it has a statically-configured IP). This causes DNS/WINS/Intersite Messaging to fail to start, since they're dependent on a network connection. While I'm still attempting to find a root cause to this issue (I've done firmware updates, checked for any odd drivers/services, no luck so far), but in the meantime, I want to adjust the load order of services to ensure that the NIC binds first before these services attempt to start. The only question is, which service is it? The server is running Server 2008 R2 and only has one NIC installed. (On a side note, there are two other small but odd problems occuring with the server. The server had the issue described in KB2298620, which I've fixed. The other problem occurs in Windows Server Backup. No events appear in the upper portion of the window, despite the fact that backups are running in the background. Whenever I attempt to modify the backup schedule, it gives me the error "Not enough storage is available to process this command" and appears to fail, when, in fact, it actually succeeds. These may be separate issues, but something tells me that some of these might share a common root cause.)

• Failover Cluster Quorum Failing

  - by oruchreis

  Hi, I have two nodes which boots from iscsi to implement windows 2008 cluster. And I'm using disk majority option as quorum over iscsi. But when the quorum's iscsi connection failed(May be san server reset), the failover cluster is failed too. If I reset one of the nodes, it can open, but its system disk goes offline. I cant change its status as online, because it says that its reserved by failover cluster(disk is on iscsi, beacuse iscsi boot). And this disk works as readonly. Anything on it cant be deleted or written. So, I cant rejoin the node to the cluster again. I have to reinstall windows. So, what I'm asking is, how can I implement more quorum backup? I mean, can I use both disk majority and file share majority at same time? AFAIK, every nodes also keep the quorum's copy too. But I don't know sometimes san servers goes offline. And quorum's iscsi connection and nodes' iscsi connections get lost. So, nor the quorum that is kept in the nodes neither the quorum iscsi disk is not enough to start the cluster again. I want to use both disk majority and file share majority at the same time. Can I do this? Have you any other suggestion? Regards.

• Memory overcommitment on VmWare ESXi 5.0

  - by Tibor

  I would like to understand better the possibilities of VmWare ESXi memory overcommitment. I've read this paper from VmWare, so I am familiar with general concepts, such as hypervisor swapping, memory balooning and page sharing. It seems that a combination of these techniques allows for quite a large degree of overcommitment. However, I am not sure. I am deploying a virtual test lab comprising of 4 identical sets of virtual servers and workstations and a couple of virtual router instances. Overall, I expect to be running around 20 virtual machines with Windows XP, Windows 7 and Ubuntu for workstation hosts as well as CentOS and Windows 2008 Server instances for servers. The problem is, however, that the host machine only has 12GB of RAM and I don't have an option to stuff in some more. I would like to know what is the best option to configure hosts in order to achieve reasonable performance within the constrains. I have these two options: Allocate as little as possible of RAM to each virtual machine. Allocate an extraordinary amount (such as 4 GB per instance) and let the baloon driver do the rest. Something else? Which would work better? Machines will mostly be idle, so I don't have any major performance expectations, but they should run reasonably smoothly nevertheless.

• Network Security Device/Software

  - by Campo

  We currently run Symantec Antivirus Corporate 10.2. The software is really easy to manage on a network but the actual virus detection isn't bad but the malware detection is crap. We recently were infected with a email bot that got us put on some block lists. This has been resolved. I cannot have that happen again. I would like to find a program as easy to manage as symantec that I can install on all the user's workstations as well as the servers. We run a windows 2003 domain. We have a couple 2008 test servers in the environment. Most of the workstations are xp though I am using windows 7 and symantect is not compatible with this OS... So we need a solution that would cover all those operating systems. If it could be installed on macs too that would be a bonus though not necessary at all. This software must detect: Viruses AND Malware I am looking for something that combines the features in anti-malware programs like malwarebytes or spybot with an antivirus program like symantec or AVG. Alternatively if there is a piece of hardware that is a firewall, router, and packet inspection for virus/spam that would be the most ideal solution. I then could supplement with a piece of software that could pickup what the hardware misses. Thank you for your suggestions.

• Windows 7 logon script net use fails

  - by Bryan

  Our network PCs currently consists of Windows XP Professional on a mixed 2008/2003 domain, with exception to one machine, which is a new Windows 7 PC we have bought for testing before we deploy the operating system. But we have discovered a problem with our logon script which automatically maps network drives for our users. The logon scripts are done via User GPOs, but the script itself is just a .cmd file using net use. The permissions are perfectly fine, as the same user can log on to a Windows XP machine and get their drives mapped without problem, but this one drive mapping constantly fails. This is repeatable using the net use command, and fails every time - it actually prompts the user for a username and password when executed interactively, yet if we enter \\server\share from a run dialog, the contents of the network share appear and are accessible without any further authentication. The Windows 7 PC (just like the XP systems) are domain members and the account being used is a domain account, which does have access to the share (as stated, it works fine on XP). I fail to understand what is happening here, as other shares on the server get mapped on the Windows 7 system. More info: The effective permissions of the share in question only grant the user 'list' permission on the root directory, the share permissions are 'everyone,full control'. I've created a new share with the same permissions just to test if it was down to the 'list' permissions on the root directory, but the Windows 7 machine maps this one fine.
