esxi 5.1 (free) reduce vmdk size (not zero the data, reduce size by a certain amount) [duplicate]

  • 772

I have set 100GB as the limit of my VMDK. I can reduce the size by using the vmkfstools -k my.vmdk

What I would really like to do is take 20GB off the thick size of the disk.

Any advice? I would prefer something in the CLI vs using the converter but open to advice :).

  1. You can convert the drive from a thick-provisioned disk to a thin-proivisoned disk. We're missing a little information, though. How much of the 100GB is in use right now? If it's say, 60-70GB, is this exercise worth it?

    The process is simple in a vSphere situation where you have the ability to migrate the VM to another datastore. If you need to do this via the command line, the steps are more involved.
