  • 1.  No more space for virtual disk??

    Posted Sep 21, 2015 05:28 AM
    【Issue】Current Configuration:
        The VM Hard Disk: Thin Provision 1T

        The VMDK of the VM: 800GB

        The datasotre used by the VM: 840 GB

        The Disk Utilization in the guest OS (Windows Server 2008) of the VM : 400GB
        ESXi Version: 6.0

       The VM runs well for a long time.
       However, one day the vCenter shows the error "no more space for virtual disk" used by the VM and caused the VM suspended.
       The space of the virtual disk is sufficient for the VM (since the guest OS only consumes 400GB and the VMDK is 800GB).

       Why the vCenter detects no more space error and suspend the VM?

       p.s. After answer the question and power on the VM, the VM runs well ( we don't purge any data of the guest VM.. )

    Thank you!!!

    You may need reclaim the free blocks to release space on datastore, take a look here: Reclaim disk space from Thin Provisioned disks | Rickard Nobel

    Thank you Richardson.

    The website of the link I couldn't open but I think I know what you're suggesting.

    Actually, I am not looking for the way to reclaim thin provisioned disk space since I am not bothered by the used space of the datastore.

    Since "When a file is deleted from the virtual machine OS the free space is available for the OS", I can't figure out why the OS of the VM consumes less far away from used storage but vCenter still gives the "no more space of the virtual disk" error.

    What does the datastore volume look like on the SAN?  You may need to extend it on the SAN side as it may be choking on the ability to clear files before it fills up.
