Re: Can't migrate a virtual disk

Hi,

 

Seems that we are running into a maxed out config Issue. I am not sure how you were able to create a VMDK of 2TB in the first place,? because the maximum size for a VMDK on a VMFS volume is 2TB -512 bytes , =~ (1.98TB) Its a limitation of VMFS and only RDM's can be greater than 2TB.

 

The below is the configuration maximums for a  VMFS5

 

Volume size :  64TB7

Raw Device Mapping size (virtual compatibility)  : 2TB minus 512 bytes

Raw Device Mapping size (physical compatibility : 64TB

Block size:  1MB

File size :  2TB minus 512 bytes

 

 

If the above is what is the problem for us, then we could the below options.

 

1. Attach the VMDK to a VM and use the VMware Converter, do a V2V and reduce the size of the VMDK at destination. - ( The best option - bcoz you can even change it to a thin provisioned at the destination ).

 

Else

 

2 . Wait till the release of ESXi 5.5 which can support upto 64TB vmdk.

 

 

Thanks,
Avinash
