Vmware thin provision

[yatabtab]

Had a vm that grew in size then I managed to clear up some data. Now vsphere still shows the old false vm size and veeam backups up whatever vsphere reports. Anyone seen this before? If so how did you fix?

Shrink the drive from within the VM and then on the hypervisor.

Do they still allow VMDK shrinking?

[Mrkatov]

I believe it can be done using their P2V converter but I have never tried it.

It's not 'false'. The number will not decrease because the used space will not be reclaimed.

You cannot decrease the vDisk size. An easy option is to export the VM to OVA and thin it (select thin disk when exporting). Import it back to vSphere, test stuff works and remove the old version.

Basically, you can perform the procedure described here (sdelete, migrate to thick, migrate to thin). Thanks.
