shweta agarwal reopened CLOUDSTACK-6224:
----------------------------------------
I tried to verify the bug .
Bug is still not fixed.
I created a VM on vmware 5.1 with a template of size 2GB and data disk of size
5GB .
Then i created a VM snapshot of this VM
When usage is generated for the VM snapshot the usage for root disk is only
37KB , for data disk usage was fine.
> VM Snapshot inconsistent size

> During the creation of VM Snapshot [VMware], resulting size is written in
> table „volumes”, column vm_snapshot_chain_size. It seems that size of a VM
> Snapshot is calculated manually via the method getVMSnapshotChainSize(..)
> and it gives overexpected result ( hundreds of terabytes ) and is much larger
> than the filesize, that we can see in VMware itself. By calculating the vmdk
> and vmsn file sizes manually. Xen VM snapshots [disks only] give similar
> results. For me it seems that either the method works incorrectly, either it
> loops between some simlinks.
