> Assuming initial devcloud state... 
> I added a cache for the S3 storage like this. 
> on devcloud machine as root: 
> # mkdir /opt/storage/cache 
> # vi /etc/exports (and append this line) 
> /opt/storage/cache *(rw,no_subtree_check,no_root_squash,fsid=9999) 
> # exportfs -a 
> On Mgmt server GUI: 
> 1. navigate to infrastructure -> secondary storage 
> 2. delete the NFS SS. 
> 3. add S3 storage for Cloudian (I used 60000 as the timeouts - assuming millis). I used the /opt/storage/cache thing as the s3 cache.
> 4. nav to templates 
> 5. register a new template (I uploaded tinyLinux again as "mytiny" (5.3 64bit)). 
> 6. confirm with s3cmd that 2 objects are now on S3. 
> --------- s3 objects -------

> --------- the new s3 object ------- 
> 8. Go to instance and create a new choosing the "mytiny" template which we registered. 
> 9. launch it after selecting all defaults. 
> 10. wait until it starts.
> 11. nav to storage. I see ROOT-8. Click on this to open.
> 12. click the camera to take the snapshot.
> after a pause I get a popup
>      "Failed to create snapshot due to an internal error creating snapshot for volume 8"
> Also on the mgmt terminal I get the following log entry (only 1):
>     INFO  [user.snapshot.CreateSnapshotCmd] (Job-Executor-8:job-16) VOLSS: createSnapshotCmd starts:1372321251009
> If I check the "view snapshots" button under storage, I can however see the snapshot. It says its on primary. I'm expecting it to go to secondary storage though. Nothing is in the S3 logs and no snapshots.
> If I try to delete that snapshot from here I get this error in the logs:
