PlateSpin Migrate and PlateSpin Protect used with ESX target server.
During a conversion to a VMware Infrastructure/ESX 3 Server, the "Create Virtual Machine" step goes into a recoverable error with the following message:
The CreateVM_Task submitted to the VMware ESX server failed: Insufficient disk space on datastore
The CreateVM_Task submitted to the VMware ESX server failed: A general system error occurred: The file is too big for the filesystem
The above error will occur if any of the following is true:
- There is not enough disk space on the target host to create the .vmdk file
- The block size of the VMFS partition needs to be increased to support the desired size of the .vmdk
The default configuration of the VMFS File System on a VMware Infrastructre/ESX 3 Server uses a block-size of 1 MB - which limits any individual .vmdk file to a maximum size of 256 GB.
In order to be able to create a virtual disk with a size greater than 256 GB, the VMFS File System must be configured to use a larger block-size such as 2 or 4 MB.
Please note that in order to apply the larger block size change, users will need to do one of the following:
- Create a new VMFS partition with the larger block size
- Re-format the existing VMFS partition to apply the large block size change
