Thank you for your reply with the options.
I like the vmkfstools option, and I've just tried it like this:
/vmfs/volumes # vmkfstools -i "ReadyNAS-iSCSI/CUCM-Pub 9.x/CUCM-Pub 9.x.vmdk" "QNAP/CUCM-Pub9.x/CUCM-Pub 9.x.vmdk" -d thin
Unfortunately, I received the following error:
Destination disk format: VMFS thin-provisioned
Failed to clone object parameters
Is there a way to get the vmkfstools to clone a virtual disk to a thin-provisioned VMFS datastore?
Thank you!
