I have a drive that is VMWare Thick Provisioned with a format of Thick Provisioned Eager Zero.

I need to expand this drive by 10Gb, but unlike Thick Provisioned Lazy zero, I can't expand that drive while the machine is on, and unsure of what needs to be done while the machine is off.

How do I expand a drive of this type?

There is a blog post on how to do that.

Extending an EagerZeroedThick Disk

In summary to extend while keeping in eager zeroed mode, use CLI. to extend it so that it reaches 90 Gigabytes afterwards, do the following:

# vmkfstools -X 90G -d eagerzeroedthick  /vmfs/volumes/datastore1/GUEST-001/DISK_1.vmdk                                              


Grow: 100% done. All data on '/vmfs/volumes/datastore1/GUEST-001/DISK_1.vmdk' will be overwritten with zeros from sector <7891200> onwards.
Zeroing: 100% done.
