>             Project: CloudStack
>          Issue Type: Bug
>      Security Level: Public(Anyone can view this level - this is the default.) 
>         Environment: XS 6.0.2
>            Reporter: Sanjay Tripathi
>            Assignee: Sanjay Tripathi
>            Priority: Critical
>             Fix For: 4.5.0

> The following situation happened:
> 1. Deploying VM from a template.
> 2. As part of the deploy CS would do a storage.PrimaryStorageDownloadCommand to get the
vhd/template to primary storage.
> 3. If there is some type of MTU problem in the network, as a result the copying of the
VHD will fail. VHD files in primary storage would end up with corrupt/missing header.
> 4. Since the copy command fails, CS tried to delete the vdi using VDI.destroy command
> 5. VDI.destroy fails because VDI file has missing/corrupt header
> 6. CS fails on downloading template and moves to another primary storage or cluster.
> This process repeated until all XS clusters in the zone had a corrupt VDI in the storage.
This causes future deploys (because they require sr-scan) to fail because the primary storages
contain corrupt VDIs.
