vCD 5.1 - Snapshot Error based on Storage Quota

The error that I am getting completely makes sense and maybe this is more of a feature request but I can't find a good way around it currently.

Snapshot Error: The requested operation will exceed the VDC's storage quota.

I have an Organization setup based on the allocation model.  They have 100GB of allowed storage and the VM is 75GB.  They cannot take a snapshot as it will exceed the storage quota.  I understand that the VM technically has a second delta disk now and is allocated as 150GB which is why the error happens.  Maybe a checkbox to allow over allocation only during snapshots would be nice.  Think of the issues when you try to snap a vApp containing a couple 50GB VM's and all the extra storage that would be needed there.

I even tried creating a new Org with allowed thin provisioning, built a new VM, and it still gives the error because of the allocation.

Hi ,

I have a VDC where only one VM is there.

Overall storage allocated of VDC(USVDC) is 15 TB.

Storage used is 12.8 TB

Windows VM total size is 12.8 TB

When we take snapshot,we are getting the below error.Normally,the snapshot size will be 15 MB to 20 MB(while take the snapshot)and then it will grow.

[ c99c801d-b638-4eda-a82b-65e6491a1f4b ] The requested operation will exceed the VDC's storage quota: storage policy "Gold-VSAN-Policy" has 2,471,936 MB remaining, requested 12,855,296 MB.

My question,If I extend the "USVDC"storage allocation from 15 TB to 28 TB,then I can take the snapshot easily.but I cannot revert back the VDC storage allocation again to 15 TB.

Why we are getting such errors as the VM snapshot needs only minimal space not complete VM space(12.5 TB)?

Thanks, Manivel RR
