When I point to the VMDK file I get Incompatible device. I found several other VMDKs related to other VMs are attached to this VM. If you connect vSphere Client directly to an ESX host, the Raw Device Mappings option is greyed out.
#VMDK S FULL SIZE#
This will zero 8GB of the available 8.2GB (1MB Blocksize * 8192 = 8GB). Please note that you virtual disk file (VMDK) will grow to the full size during the process. Vma:/mnt/data # dd bs=1M count=8192 if=/dev/zero of=zero The best known tool is dd which should be available on all systems. There are various tools available to create zeroed blocks. Wait a couple of minutes until the process is finished. Please note that you virtual disk file (VMDK) will grow to the full size during the process. The file represents a virtual machines emulated hard drive.
This is required to reclaim space back from the virtual disk.
#VMDK S HOW TO#
This post describes how to reclaim unused space from the virtual machine. Map each of the created VMDK files to each VM. You can also use a VMDK file in VirtualBox, another popular virtualization tool that also has its own disk format. The file represents a virtual machine's emulated hard drive. When you require the capacity only once you might want to get it back from the virtual machine. Posted: (5 days ago) You can import a VMDK file to a VMware virtual machine either as you create the virtual machine or after the fact. Having thin provisioned disk is usually no longer a performance problem so it is a valid design choice even in production.Ī common issue with thin disks is that the size will grow when required, but never shrink. I am not considering databases, applications or fileservers which will grow constantly. I do not know a single system where you do not have at least 10GB of free space for OS disks. Thin provisioned disks are a great feature to save capacity as you virtual machines filesystem will never use the full capacity.
