[jira] [Commented] (CLOUDSTACK-3903) Snapshot Creation Fails in
Vmware setup with permissions issue.
[ https://issues.apache.org/jira/browse/CLOUDSTACK-3903?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=13722428#comment-13722428 ]
Koushik Das commented on CLOUDSTACK-3903:
-----------------------------------------
Permission issue is happening and the reason is similar to the one observed in CLOUDSTACK-3506. The NFS setup is not correct and permission is not getting set to 0755 on intermediate folders in the secondary store.

> 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:

> 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.
