Problem VMDK file large cluster in a box

So I've been running a flavor of vmware server 2.x since its release with little or no problems. Not that it matters but my host server is a Dell Poweredge 1900 with 32 GB of RAM, running windows server 2003 x 64.  I have also 2 Windows VM that I run as a cluster in a box, and they worked very well in this way for more than 3-4 years at the time of vmware 1.x. Both virtual machines have been set up exactly as such:

SCSI 0:0 16GB & lt; - c drive

1:0 500 MB & lt; - quorum SCSI cluster

SCSI 1:1 12GB & lt; - the app cluster disk

1:2 950 GB SCSI & lt; - storage of cluster disk

SCSI 1:3) 12 GB & lt;-the sql cluster disk

1:4 250 GB & lt; - disk SCSI storage of additional cluster

What I did recently to set up a new file 2 TB since vmware server 2.x vmdk will now allow you to make files vmdk bigger than the old limit of 950 GB. This new 2 TB file was supposed to replace my 2 readers of old SCSI 1:2 and 1:4 SCSI cluster storage. After making the swap and copy all data to a vmdk file again, I noticed a problem at any moment I'm going to and move the resource cluster VMDK new 2 TB to the other server. Basically the two servers stop responding and it seems that vmware server choke on the 2 TB for some reason vmdk file any. Here's what I see in my logs any time that this happens.

Has anyone ever ran across this or has anyone ever used a file vmdk of this size as a cluster resource? As I said before that I had 0 problems with my cluster before I added this new 2 TB vmdk file...

I'm not at all surprised that you get this problems.

You use monolithicSparse vmdk type!

For cluster in a box, I highly recommend flat VMDK.

I wonder that it worked for you all with the drive more sharing

  • Problem with vmdk file based in Win7 - missing lost cause?

    Hello

    I have used VMWare for a good years now without incident, until today.

    I have a VM that today seems to have lost its base vmdk file.

    I think that the disk storage ran out of room when the pc has been closed for the last, but it seems odd this missing file.

    It is worth noting that the virtual machine was actually suspended rather close.

    Here's a screenshot of what looks like the directory.

    There was no 7.vmdk Windows' file and I could not recover despite some drive train recovery tools.

    So my question is, is it a lost cause?

    The file that is there now, I copied from one of the other virtual machines and renamed it (not that it works) in the hope that I could continue somehow.

    I have read that these files are linked and the parent / child ID must be defined, but all discussions talk about modifying the files and I don't seem to be able to do this in windows. Is there a tool for this or I'm wasting my time?

    I did a lot of research and reading without result, so thought I'd come and ask the experts

    I'm a little confused on the different vmdk files.

    Given the dates, I suppose it works actually in the file-000002, since the others do not appear to have been changed in a while.

    If this is the case, why I need another and somehow I can come back by using only a single file and release a load of disk space?

    It also means that the 000002 file displays the current status of the disk in it?

    None of the other virtual machines has more than a vmdk file.

    Any help would be greatly appreciated.

    Thank you very much

    John.

    vm_win7.jpg

    replaced basedisk has done a good job - John is to copy its files to a second vmdk now - can't say anything about their status at the present time.

    The fact that the partition was visible and could not repair the partitiontable or bootsectors makes it look promising

  • How to retrieve a large vmdk file in ESXi?

    Hello

    I desperately need help. I have a server with ESXi. One of the virtual machines in this server had a top serving our customers mail server. We had to move this mail server to a different location. When I tried to re - create the virtual machine with the same e-mail server (for testing purposes) all of a sudden, the big vmdk file disappeared. Of course, when I try to load the machine now, it gives an error "file not found".

    I read on other pages on how to recreate the vmdk file, but they were all on ESX and has not worked for me. The best method was present.

    Please can someone help me on how I can get the big vmdk file?

    Thanks in advance.

    Kind regards

    seedeg

    OK... explaining:

    A VMDK file is the union between a VMNAME.vmdk header file and a file VMNAME - flat hard. The datastore browser, when you have both, they appear as one, as on the second screenshot.

    The virtual machine always point to the VMNAME.vmdk file, which points to the VMNAME - flat hard, which really contains the data. You will never see the dish once that these two files are located on the data store, but sometimes people delete it and I was suggesting that it may have happened to you.

    Hard 00000files are instant. They are the changes on the original flat file logs, but if you don't have it you can't rebuild since the change to connect because you do not have the original data map.

    You may need to call a company to recover files from disks, or look for some tools which does this in VMFS volumes - I don't know everything, since VMFS is too simple and not to keep track of deleted files unless you take a snapshot of the file system in some time.

    If you do not have backups and can produce the VMDK or the flar. VMDK no matter where, there is nothing more I can do to help you. Sorry about that

  • Problem in a mount vmdk file: could not get a VIM ticket for this virtual disk.

    Hello

    I have a virtual machine on ESX 3.0.1

    When I get the file vmdk directly from ESX, it gets mounted successfully from the command prompt using the mount utility.

    But when I try to mount the vmdk by VI file it displays error "Unable to get a VIM ticket for this virtual disk" on the command line.

    I tried this for other virtual machines also and most of them work.

    What is the reason for the error "unable to get a ticket for this virtual disk VIM.

    How can I get this vmdk file mounted by VI?

    Can you show the virtual computers view of inventory? The image you show of hosts and Clusters discovered.

  • Expanded VMDK files

    Hello

    I have a strange problem here. I have a box of Red Hat Linux that is put into service with 3 disks. HDD1 (thinly provisioned) operating root partition and that allotted space is 10 GB inside the BONE, but it is 60 GB upgraded from VMWare. For some reason the VMDK file is grown up (provisioned) to 60 GB but inside the BONE when I run df - h, it is show / 3 GB used out of 10 GB.

    I don't take any cliché, so there is no way, it's because of this.

    Can Linux OS can cause HDD1 for grown in VMWare level without affecting the partitions?

    Help, please

    Thanks in advance.

    As mentioned by Tsjo, the 'size' is what is physically used by the virtual machine and the 'set up' is the size that you defined during the creation of the virtual disc service end. "Configured" size you see in the virtual machine Summary tab is the maximum size that the virtual machine can use on the data store, not what it is currently using.

  • I - delta.vmdk files, non - .vmsn files. How to restore the instant guest operating system?

    Hello

    Coincidentally, using the browser data store, I've deleted almost all the files in one of the guest OS. Only files vmdk (dish and delta) have survived. So far I've managed to run (using this link http://tinyurl.com/yda5f8d ( ) the guest using OS his - flat.vmdk file and it works very well. The problem is, it's an operating system in the former State, and I would go back to the last snapshot (I have two actually).

    I have ESXi 3.5 and the use of the Mode of Tech support. So I base (flat) file and not visible (from vClient) snapshot two working files. Browser data store using I can see them under delta.vmdk - 000001-xxx and xxx-000002 - delta.vmdk. Should what kind of magic I type in the console to restore my operating system in the lates snapshot? It's ok to merge these snapshots in a main flat file if it would be faster or easier.

    Concerning

    Piotr

    OK, let's give it a try.

    Attached you will find a collection of files that are generated, assuming that the snapshot 000002 was the last. I'll give you the steps to make sure that the current data files will not be affected where 000001 was the last snapshot.

    1. delete the virtual machine of the inventory
    2. Download files attached to the virtual machine file
    3. Delete the w2003r2.vmsd file if it exists.
    4. Right-click on the vmx file and select "add to the inventory.
    5. Open the virtual machine settings and uncheck the box "connect to power on" for the network card (only to make sure that the virtual machine does not connect to the network, where the snapshots are not in the right order)
    6. Important: Create a new snapshot, and to ensure that the new vmdk file is referenced in the disk of the virtual machine settings

    Now you can try it without risk of turning the virtual computer and check if everything seems OK. I suggest that you take a look at the Windows event logs and check if the last entries are from the scheduled date. Because you have turned on on the VM from the file (flat) base, run 'chkdsk /f' for all readers to solve possible problems.

    If this doesn't seem to be the right order, please report and I will edit the files to make snapshot 000001 the current.

    Once everything is ok you should really consider deleting snapshots. To ensure that this does no new issues, please provide the build number of your hosts ESXi and the amount of free disk space on the data store!

  • In DatastoreBrowser vmdk file size not the same as busybox?

    Hello

    I have a few virtual machines in ESXi 4.0 U1, I installed the virtual disks as "thin" then they should grow in size, when the virtual machine is increasingly large.

    If I look at the vmdk files in the DatastoreBrowser of vSphere Client 4 is the case and I have a few files 20 GB for my Windows Server 2008 vmdk files.

    But if I look in the real file from busybox system (I use WinSCP or putty and even with Trilead VMX) then each vmdk-dish has the maximum size of 100 GB (exactly 107 GB). The vmdk file is named hard-plate here and not hard like in the DatastoreBrowser.

    If I download the file DatastoreBrowser vmdk to a Windows machine that I get a vmdk-apartment with great size and not the size specified in DatastoreBrowser.

    Surprisingly all-flat-files vmdk together (seen in WinSCP or VMX) are larger than the disk HARD Physics (500 GB).

    What is c?

    Thank you, franc

    Hello

    as said marcelo, thin discs works on the VMFS partition level. The thin disks does not exist outside of a VMFS partition.

    For example, is run you 'df - kh' you can see the real disk (distributed) of the VMFS partition space. In other words, you can see the total amount of disk space used by the thin disks of the virtual machines.

    Anyway, you turn in the busybox "ls - sh" (instead of 'ls - lh') you will see the real space of the thin virtual disk for a particular virtual machine (vmdk).

    But the problem is that tools such as winscp see the size of the disk space of the thin disks. This tools see the size of the reserved the vmdk file. Then, it copies all the file size of the disk as a thick disk. And of course, the target file system partition that will contain the thin disks, does not support thin disks.

    A thin disk with 3 GB of actual data (distributed) and a 10 GB reserved size is copied on the net by Winscp as a 10 GB drive.

    Best wishes / Saludos.

  • Vmdk file download

    Hi, when I try to download physical server data store vmdk files it downloads smaller files without problems.

    But for large files (more than 5 GB) it always communicate "insufficient system resources exist to complete the requested service.".

    I tried on several servers, but always the same problem.

    You have several choices.

    If virtual machines are closed during the copy of file, then you must use a (free) third-party utility, such as Veeam FastSCP or WinSCP or same Putty PSCP. If the virtual machines are running during the copy, consider VMware Consolidated Backup-> http://viops.vmware.com/home/docs/DOC-1392

  • LAN-Free backup of snapshots VMDK of ESX Cluster

    My intention is to perform a backup outside shots VMDK of ESX Cluster to VCB Proxy Server LAN.

    I have a scenario where I have 3 ESX servers with 3 x 800 GB LUNS in a storage group separate on a CX 310 SAN box. The Ids., (HLUs) host these 3 LUN LUN are 0, 1, and 2. All these three LUNS is a VMFS volume each on the ESX Cluster and all three LUNS are visible to all the ESX servers.

    I have a physical host that boot from SAN (the same box of CX 310 SAN) and this host will be designated as the VCB Proxy Server.

    Now, I'm going to add a 1 TB LUN to the storage group as the LUN 4 ESX servers and the Id., (HLU) host LUNS for this one will be 3. This logic unit number will be added as the 4th volume of the cluster ESX VMFS. It will also show all three ESX servers in the Cluster.

    I'll create a Windows VM 'VM2K3' on ESX Server 1, and I intend to add the volume (1 TB) entire VMFS 4th as "D:\". "drive"VM2K3 ". I'll share this disc "D:\". "and it will be mapped as drive"T:\ ". "on the VCB Proxy Server. This disk 'T:\ '. "will be the target for the storage of the VMDK to snapshot backups, in a compressed format. I use VizionCore vRanger software connection to this effect on the server VCB Proxy itself.

    Question 1.

    This scenario will provide the backup off LAN of VMDK instant?

    Question 2.

    In the case of a failure full 1 ESX Server, VMotion will be or a manual movement of the virtual from Windows "VM2K3" machine would affect the LAN-Freee of instant VMDK backup? If so, how will this affect and what will be the impact?

    Question 3.

    The "C:\". "Logic of the VCB Proxy unit number will be a 30 GB SATA LUN and the total size of the RAM on the VCB Proxy Server is 8 GB. The ability to drive "C:\". "30 GB will be sufficient to make faster given the fact that I have about 45 VMs at this point in time?

    Any help or suggestion or two in this case would be very useful.

    Hello

    A physical machine cannot directly access a VMDK in a VMFS. There may directly access LUN, that LUN could then accessible by a VM with RDM or virtual RDM mode. But why would you do it is really beyond me.

    The VCB Proxy running W2K3 and you present all your VMFS volumes (make sure that you don't have a letter assignment drive automatically enabled when you make this presentation). See http://www.vmware.com/pdf/vi3_35/esx_3/r35/vi3_35_25_vm_backup.pdf for assistance with this.

    VCB proxy then read this VMFS and copy data from it to your T:\ drive (MON).

    Remember that no two hosts can access the same logical unit number unless you use a clustered file system.

  • Random problem, download files

    I have a random problem, downloading files on different web sites. I click on the file to download and retrieve the backup file with the file name box instead, I get something like "attachment.php". He always seems to be php files.

    By clicking on the file many times to download later, it will download, but it is very frustrating.

    I went through all the guides and troubleshooting suggestions. Nothing makes no difference. I disable add-ins, antivirus etc. nothing works.

    For example, this is the last download, I tried (click on the download button):

    http://www.Pixologic.com/ZBrush/getting-started/

    I got "download.php", which is not just the zip file with a different name. It is in fact different.

    Do it a few times I finally got the zip file.

    It seems to happen on any web site. The common theme is that this '.php' is involved.

    Is this a bug? Any ideas?

    Do you not see the correct link I posted above at the bottom of the browser window if you hover over the download button?

    You can have security software as a software firewall or antivirus which is at the origin of the problems if safe mode did not help.

    Always check in the Device Manager - drivers tab to be sure the version you actually install
    presents itself. This is because some restore drivers before the most recent is installed (sound card drivers
    in particular that) so to install a driver - reboot - check that it is installed and repeat as
    necessary.

    Repeat to the manufacturers - BTW in the DO NOT RUN THEIR SCANNER device - check
    manually by model.

    Look at the sites of the manufacturer for drivers - and the manufacturer of the device manually.

    How to install a device driver in Vista Device Manager
    http://www.Vistax64.com/tutorials/193584-Device-Manager-install-driver.html

    If you update the drivers manually, then it's a good idea to disable the facilities of driver under Windows
    Updates, that leaves about Windows updates but it will not install the drivers that will be generally
    older and cause problems. If updates offers a new driver and then HIDE it (right click on it), then
    get new manually if you wish.

  • Problem opening files in MS Paint

    I'm running Windows 7 Ultimate on an ASUS Gaming Notebook aged 2 years.  All installed software is set up to receive the latest updates.


    About 3 days, 24/09/2012, UTC - 6 h, I started to experience problems opening files inside MS Paint.  Recently used files open without problems, but when I used the drill down menu file and clicked Open, the File Manager window opens but seemed not completely.  It stops before you post content in the panels on the left or right.  After waiting almost a minute, an error window opens saying that the Paint program does not react with the choice of activation of one of the 2 buttons, Debug or Cancel.
    Despite my system restarts and run virus scans, nothing seems to be broken.  I did, however, go through the Event Viewer to see what specifics have been involved in these accidents.  As I'm not a programmer or remotely competent in any language of software, the only elements that makes any sense to me were mspaint.exe & explorerframe.dll mentioned in Application event error reports as well as a series of numbers. (I also made the applet of Quicktime, 22, do not overwrite my selections of extension of file to default, programs installed that I read in another forum, it tends to do with files visual & audio) So now, I have several issues with that I hope other posters can help me:
    • Everyone knows that I have here and have been able to solve it?
    • Is it possible to uninstall, and then reinstall the paint? (I don't want to do a restore system b/c my last restore point was in April).
    • Any of you know how I can repair this situation or even help out there so I could fix the problem myself?
    • Is it possible to have reported this instance to Microsoft somewhere other than the generic return route?

    Thank you very much for reading and doubly so if you can shed some light on this dilemma.

    A restore point can be created manually, but when you use windows update a restore point is often automatic created in the update process.

    Simply type 'Restore' in the search text box programs & files, double-click the shortcut to "System Restore" which results in and follow the instructions (note the show more restore point box)

  • Reset cbt - cannot get rid of the ctk vmdk files

    Hi, I have a known problem with the backup of my virtual machines where I need to reset the CBT. The procedure I have the backup software is as follows;

    Solution:

    Please follow the steps below to reset the CBT for a specific virtual machine.

    1. turn off the virtual machine

    2. right click on the virtual machine, click on "Change settings", find the 'Options' tab and click 'settings of Configuration.

    3. set the value of 'ctkEnabled' to false

    4. set the 'scsi0:x.ctkEnabled' to false for each disk of the virtual machine in question

    5. open the source folder and remove all - CTK. VMDK files.

    6. turn on the virtual machine

    7. power off the virtual machine again. This step is necessary to update the table of CTK.

    8 turn on the virtual machine

    9 replay backup task.

    So I have 2 VMs. VM1 and VM2. Both are win2k12 r2 (they are created the same day, the same way, installation of r2 std win2k12, patches, etc...). In step 5, for both servers, even if I delete the ctk.vmdk files, they are automatically reproduced so I can't delete them. Then I continued with the neverthless steps. After step 8, I saw that for VM1, has more ctk.vmdk files so that they are deleted somewhere in the process by the server itself. So my guess is that step 5 is not relevant. The problem I have is that even if I did exactly the same thing for VM2, ctk.vmdk files are never deleted. I reboot 3 times, I tried to manually remove them several times, they always, never to return, they are deleted.

    So, basically, I can't reset the cbt on VM2. I double check this ctkenabled are all 'fake' (tried also uppercase) still no luck. Any ideas how I could get rid of these ctk.vmdk files?

    Thank you

    Hi, proved that there was a snapshot. As soon as I deleted it, the ctk files disappeared.
