OK, I have been able to reproduce this in a simple environment using only
NFS.
I create a VM whose root disk resides on an NFS primary storage. I take a
snapshot of this root disk. I then migrate the root disk from one NFS primary
storage to another. The volume is no longer associated with the snapshot and
the removed cell for the snapshot in the cloud.snapshots table has a date in it.

> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the

> Components: Storage Controller
> Affects Versions: 4.8.0
> Environment: Xen Server

> 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.
