RHEV3.1Beta : RHEV-M in a spin when removing a disk from a VM.

Hi

I've created a VM in 3.1beta, added a couple of disks from a single storage domain and then attempted to remove one of the disks.

This appears to have sent RHEVM into a spin.

I'm seeing a looping java exception in the engine log which states :-

2012-08-22 11:57:50,210 INFO  [org.ovirt.engine.core.bll.EntityAsyncTask] (pool-4-thread-45) EntityAsyncTask::HandleEndActionResult [within thread]: EndAction for action type RemoveDisk completed, handling the result.
2012-08-22 11:57:50,210 INFO  [org.ovirt.engine.core.bll.EntityAsyncTask] (pool-4-thread-45) EntityAsyncTask::HandleEndActionResult [within thread]: EndAction for action type RemoveDisk hasnt succeeded, not clearing tasks, will attempt again next polling.
 

I can confirm that the underlining logical volume no longer exists at the hypervisor(s) level but this doesn't seem to have been acknowledged by the Manager.  A reboot of the hypervisors and manager has had no effect.
