> Key: CLOUDSTACK-8826
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-8826
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: XenServer
> Affects Versions: 4.6.0
> Reporter: Koushik Das
> Assignee: Koushik Das
> Fix For: 4.6.0
>
>
> Random failures were seen in XS attach/detach volume test scenarios (many
> attach/detach were performed on the same VM over a span of 24 hrs).
> The failures happened as the device id for attaching volume wasn't available
> in HV. Some detached volume didn't got cleaned up properly and so the device
> id wasn't released.
> The fix would be clean up stale volumes before attaching new ones so the
> device slots are released. Also using the device id should be best effort and
> if that particular id is not available in XS, it should fallback on using an
> id that is available and automatically assigned.
