> Key: CLOUDSTACK-3903
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3903
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Snapshot
> Affects Versions: 4.2.0
> Environment: VMware.
> Reporter: Kiran Koneti
> Assignee: Koushik Das
> Priority: Blocker
> Fix For: 4.2.0
>
>
> Steps followed are as below:
> 1)Created an Advanced ZOne setup in the VMware.
> 2)Created a VM with root disk and Data disk,.
> 3)Once the VM is up tried to take the snapshot of the Root disk.
> 4)The snapshot creation was initiated but failed to create the snapshot as
> there are no permissions in the secondary storage to create directory for the
> snapshot.
> The error messages are as below:

> permissions for the Template or snapshots are observed only in the case of
> VMware.
