Thomas O'Dowd commented on CLOUDSTACK-3229:
-------------------------------------------
Ok. I blew away my devcloud instance and created it again from scratch. I also
blew away cloudstack and re-cloned it and checked out 4.2.
Still the same problem.

I tried running df a few times when the snapshot was in progress and caught
this.

> Key: CLOUDSTACK-3229
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-3229
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Affects Versions: 4.2.0
> Environment: chrome on linux
> devcloud
> Cloudian or Amazon S3 Object store
> Reporter: Thomas O'Dowd
> Assignee: Min Chen
> Priority: Blocker
> Fix For: 4.2.0
>
> Attachments: SMlog, SMlog.last_5000_lines.txt

> 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 -------

> 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):

> 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.
