Kiran Koneti created CLOUDSTACK-3903:
----------------------------------------
Summary: Snapshot Creation Fails in Vmware setup with permissions
issue.
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
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:

Then later manually gave permissions to the secondary storage and the snapshot
creation was successful.
Note: Not sure weather this is the CS issue or the storage issue as the issue
is not seen in case of Xen or KVm setup's. The issue related to the permissions
for the Template or snapshots are observed only in the case of VMware.
