Impossible to clone virtual machines to VSAN datastore

Hi all

Whenever we try to clone a virtual machine using vCenter vSAN not store data to the vSAN data store fails with the following error.

File /vmfs/volumes/540024e7-2d8bb59e-0bef-40a8f0305c2c/blr7-dhcp-1/***.vmdk not found.

This post should help determine the number of hosts.

VSAN part 25 - hosts much-needed to tolerate failures? CormacHogan.com

The number of disks is harder once you start adding bandwidth, because you also have to take into components witness account.

Each band will require a disc, and you increase FTT, you will need to double the number of disks you want to mirror any of the components score. And then, of course, welcome the witnesses.

  • Problem with script to clone virtual machines

    Hello

    I created a script to clone virtual machines on a regular basis around a method posted by LucD and Simon Long here or on their blogs.

    # Create new snapshot clone
    $CloneSnap = $VM | New-Snapshot - name "Instant Test" - Quiesce

    # Get the managed folder object reference
    $CloneFolder = $VmView.parent
    # Construction specification clone
    $CloneSpec = new-object Vmware.Vim.VirtualMachineCloneSpec
    $CloneSpec.Snapshot = $VmView.Snapshot.CurrentSnapshot
    # Make the linked disc specification
    $CloneSpec.Location = new-object Vmware.Vim.VirtualMachineRelocateSpec

    I want to use in an environment composed of 3 servers ESXi 4.0 with a local data store each. This works well in my test environment, but not in that productive.

    In a comment on his blog, made Simon refers to an error in the data store, but it seems very well here.

    By comparing the values of the characteristics to those of my testbed everything looks good, too.

    Does anyone of you can tell me where to look for the problem?

    Thanks in advance

    Christian

    That's correct, 1 by Server default resource pool.

    You can do

    Get-ResourcePool-name resources-site (Get - VMHost - name MyEsx)

    to get the default pool for a specific ESX Server

    CAB, you add a line in your original script

    $CloneSpec.Location.Pool = (get-ResourcePool-name resources-site (Get - VMHost - name MyEsx)). Extensiondata.MoRef

    This should be the correct MoRef

    The message seems to indicate that the target VM already partially exist.

    Remove it before you run your script once again.

  • Clone virtual machine configuration

    Hello

    I have a requirement to clone a single copy of the configuration of the VM in a datacenter to another data center.

    We essentially use HUR to do a replication of the storage of a domain controller to another. Once replication is complete and has been shared, we climb the target LUN with Signature data warehouses are ' option and the same data store name. With that, most disk mappings is lost in particular on the virtual machines with large number of disks and we eventually remove these drives and do a manual mapping with the same SCSI controller than source VM.

    My requirement is I want to automate this process and for which I need to capture details first source below and then reproduce the same destination VM.

    Source VM

    VMDK path with data store name

    VMDK mapping to each scsi controller.

    The VMDK disk size

    Mappings of RDM

    SCSI controller shares (if any)

    With the above information, I am looking for script map VMDK disks with the same data store name and the same number of SCSI controller to destination.

    If someone could help me, that would be great and I will save a lot of time spent on manual mapping.

  • Question of clone Virtual Machine

    When you clone a virtual machine by using the vSphere 4.1 client and it's personalization of the guest operating system, and he said "customization Windows resources are not found on the server.", what it refers to?  The server vCenter, the local PC or the VM I'm cloning?

    Using the stand-alone converter, I know put the correct sysprep files in the user folder, but I don't see how that comes into play here.

    First thing I would try is a reboot, but given the error, I would not hold my breath on this binding.

    The error messages seem to suggest that some drivers are corrupted. The only way to solve, which is by uninstalling VMware Fusion 8, restart OS X (ensuring that no driver remains persistent), then install VMware Fusion 8 again.

    Note, that this will not delete your virtual machines (with additional backups is always a good thing if)

  • Impossible to expand virtual machine using workstation 8.04 disk

    Hello

    I recently installed workstation 8.04 on my Vista 32 with no problems.

    Then, I installed Win 7 ultimate in my computer again without any problems.

    Now, I tried to extend the VM disk but got the error below:

    There is not enough space on the file system for the selected operation.

    There are 19 GB free on the host (Vista) and I expanded only VM 5 GB hard drive, but I still get the same error.

    The virtual computer is in one file.

    Thanks in advance for any help.

    I guess that the virtual disk to the virtual machine is a unique hard (not a 2 GB sparse disk) file. In this case temporarily resize the virtual disk requires additional disk space, because the content of the virtual disk is copied to the new virtual disk file.

    I had this problem some time, and it wasn't the SID of the OS but the ID of the WSUS client.  This can be regenerated on each client by following these steps:

    b. remove the PingID SUSClientID and AccountDomainSID values

  • Cannot start multiple virtual machines.  Maybe I corrupted the model

    We had problems with disk space, and I was looking around to see if he had left garbage data store.  I am very new to VM, but even though I'm new I'm responsible for helping maintain.  So I learn a lesson the hard way.

    I found a number of virtual machines in organized which did not seem to relate to existing models.  For example, we have a model name 000729-Server2008 Server 2008, that they are in lm401\729.  But it appers to be a clone of 729 to lm401\16.  I'm going to guess that 16 was the original version and changes or clones have been made for him and we are now sitting to 729.

    Then I moved 16 in another data store, but it failed because there is a lock on the hard master.  So I moved everything back.  Now, when we try to start up of VMs driven from this model we get "file & lt; filename not specified & gt; not found"I went back and tried to deploy and supply on the model but I get

    Simplest is to clone virtual machines, but this feature is not available in free ESXi, you have vCenter.

  • Virtual MACHINE running on two hosts after hung vmotion

    Hello

    I started a VMotion of virtual machine by host A to host B. The request got hung at 65% for several hours. I restarted the VCenter service, registered to vsphere. The process was running is longer, but now the virtual machine appears on the Host A and host B.

    The Cluster-'Virtual Machine' tab displays the virtual machine and cycles between two hosts seconds couple?

    Anyone seen this before? How can I fix it? Thanks in advance!

    First of all, it's impossible.  A virtual machine cannot be in 2 places at once.  It's just in the transition.

    Secondly, vCenter manages the process but it doesn't actually do the vMotion, ESX hosts are.

    What is happening is life of the virtual machine on the host only until the end of the evolution towards the other host (somewhere around 97%) when the transfer is confirmed with the new host.

    Best thing to do is to restart the services of management on both hosts and see if that frees the vMotion.

  • MPIO inside a guest virtual machine?

    Is it supported to configure MPIO inside a guest OS running on esxi4.1?

    I was looking at our configuration of Exchange virtual computer and for some reason any consultant configured our message Exchange store by using of Windows Iscsi initiator. Currently it has only a single session in the message store. That said, the virtual network adapter that is used for the iscsi initiator is connected to a vswitch configured for Iscsi traffic with 2 adapters, which should cover the aspect of redundancy. Not sure if it's useful to have multiple NICs configured inside the guest to use MPIO?

    I've seen some old messages in this regard, and it seemed that it was not "supported, but I thought I would check to see if something has changed."

    Thank you
    Kevin

    Closer to you, you could get is 68 of the document "vSphere storage" under the "SAN iSCSI ESXi Restrictions" section:
