But I should also point out that you are correct in saying that in the event
of a failed attempt to create a new snapshot, we should remove the (delta)
snapshot from primary storage (as it might act as a false delta if we need to
take a future snapshot).

> Key: CLOUDSTACK-9572
> URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9572
> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: Storage Controller
> Affects Versions: 4.8.0
> Environment: Xen Server
> Reporter: subhash yedugundla
> Priority: Major
> Fix For: 4.8.1
>
>
> Issue Description
> ===============
> 1. Create an instance on the local storage on any host
> 2. Create a scheduled snapshot of the volume:
> 3. Wait until ACS created the snapshot. ACS is creating a snapshot on local
> storage and is transferring this snapshot to secondary storage. But the
> latest snapshot on local storage will stay there. This is as expected.
> 4. Migrate the instance to another XenServer host with ACS UI and Storage
> Live Migration
> 5. The Snapshot on the old host on local storage will not be cleaned up and
> is staying on local storage. So local storage will fill up with unneeded
> snapshots.
