WorkspacePersistenceDB not updated after workspace --shutdown

You need to
before you can comment on or make changes to this bug.
When terminating a workspace using the workspace --shutdown parameter it does
not appear that the WorkspacePersistenceDB is being updated with current
available resources. The following error message is received by the client
after trying to deploy the same image (same specifications) that was just
terminated using the --shutdown parameter.
Error creating workspace resource: [Caused by: No resource pool has an
As well the /opt/workspace/secureimages directory on the worker node is left
with the propogated image and the client's terminal doesn't receive the
termination notice, leaving it hanging.
Similar problems are encountered when the Shutdown time is left to expire while
a workspace is running.
The slot will be occupied until WSRF resource termination passes. Shutdown
moves the VM back to the Propagated state, you could for example call --start
on it at this point.
Or did you also call --destroy and see this behavior? That would be a
Subject: Re: WorkspacePersistenceDB not updated after workspace
Thank you for clarifying that the slot is maintained until WSRF resource
termination passes. However, further inspection suggests that the
WorkspacePersistenceDB is not being updated even long after the resource
termination time has expired. Attempts have been made using both the
--shutdown parameter and allowing shutdown time to expire. In both
cases after the WSRF resource termination passes it doesn't appear that
the resources are being freed up. This is true for local and propagated
As well to confirm, when --destroy, is used to terminate a workspace the
WorkspacePersistenceDB seems to be properly updated.
I have also tried to --start a workspace I just --shutdown before the
resource termination time expired and the terminal comes back with
However, querying the worker node with xm list shows that the workspace
has not been restarted.

Thanks for looking into this, will confirm and fix shortly.
I can't recreate this here with TP1.2.3, though I am not using a real Xen
backend which I will do tomorrow.
Is it possible to get logs from you? If so, you can send them to me privately
if there is information you would not like to be archived like IP addresses
Is your default shutdown method set to trash? Bug 5345 could account for some
of these issues if so.

Where do I set the default shutdown method and what are my choices? Is this
covered anywhere in documentation?
Oh, this interface page SHOULD have this but it doesn't, it was introduced in
TP1.2. Will update the documentation for next release.
It's an optional part of the deployment request:
<xs:element ref="ShutdownMechanism" minOccurs="0"/>
Only supported value is "Trash", otherwise leave it out for normal shutdown.
This feature was added to support the situation where many VMs are started off
of the same template image but it is unecessary to unpropagate them and save
the "result". The prime example is an image that is used as a node in a pool
of worker nodes driven by a batch system, mirroring the situation on most grid
sites but dynamically adding and removing worker nodes.
I don't see this issue in TP1.3.0 (available shortly)
There was a bug in the TP1.2.3 code I know of that is related to this.
In ResourcePoolUtil#retireMem(), there was this line:
Which should look like so
This update is in workspace_tp_1_3_0_branch
Regarding Comment #7, that information will be included in the TP1.3 docs.
