Thomas O'Dowd commented on CLOUDSTACK-3229:
-------------------------------------------
Ok... I've found a suspect package which looks like it may be the right one. It
is already installed on devcloud. The only thing is that the util.py module is
not under /opt/xensource/sm but instead is under /usr/lib/xcp/sm/
root@devcloud:/# dpkg -L xcp-storage-managers

So, I've just created a symlink as John suggested as follows and will try this
again.

> Object_Store_Refactor - Snapshot fails due to an internal error
> ---------------------------------------------------------------
>
> 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
> Priority: Critical
>
> 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 -------
> template/tmpl/1/1/routing-1/acton-systemvm-02062012.vhd.bz2

> --------- s3 objects -------
> 7. I restarted the management server at this point which actually resulted in
> another object on S3.
> --------- the new s3 object -------

> 50430464 "4afac316e865adf74ca1a8039fae7399-10"
> --------- 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:
> ERROR [cloud.async.AsyncJobManagerImpl] (Job-Executor-12:job-20) Unexpected
> exception while executing
