VMware convert eager zeroed disk to lazy zeroed

Last updated: January 2, 2023 at 12:15

Conversion to lazy zeroed might not work, so better to convert disk to thin. and then do vmotion to lazy zeroed.

vmkfstools -i /vmfs/volumes/datastoreName/VMName/VMName.vmdk /vmfs/volumes/datastoreName/VMName/temp/VMName.vmdk -d zeroedthick


vmkfstools -i /vmfs/volumes/myVMFS/templates/gold-primary.vmdk /vmfs/volumes/myVMFS/myOS.vmdk -d thin
