Github user jburwell commented on the issue:
https://github.com/apache/cloudstack/pull/1710
@ozhanrk @ustcweizhou I asked a [functionality
question](https://github.com/apache/cloudstack/pull/1710#issuecomment-257697031)
regarding this functionality to which I cannot find an answer. Namely, that
this patch is deleting snapshots in a circumstance where not all users want
them deleted.
> Deleting Snapshot From Primary Storage Fails on RBD Storage if you already
> delete vm's itself

> Project: CloudStack
> Issue Type: Bug
> Security Level: Public(Anyone can view this level - this is the
> default.)
> Components: KVM, Snapshot, Storage Controller
> Affects Versions: 4.9.0
> Environment: Ubuntu 14.04 Management Server + Ubuntu 14.04 KVM

> Hi;
> We plan to store vm snapshots as vm backups on secondary storage while we
> still destroyed/expunged related vm. The idea is good there was a bug which
> blocks this idea to work and it was fixed with CLOUDSTACK-9297 bug.
> Normally with 4.9 release we expected this idea to work on our on our 4.9 ACS
> environment but we noticed that because we are using rbd as primary storage
> we need to fix one minor bug for this idea to work.
> The problem occurs because CLOUDSTACK-8302 bug fixed on 4.9 release and it
> block our idea to work. If you destroy a vm which is on RBD Storage as
> primary storage it also deletes any related snapshots of that vm on Primary
> RBD Storage. So after vm destroy no disk file or snapshot file over RBD
> Storage. This is good for cleanup purposes on primary storage but
> XenserverSnapshotStrategy.deleteSnapshot class method did not expect this to
> happen.
> org.apache.cloudstack.storage.snapshot.XenserverSnapshotStrategy.deleteSnapshot
> method receives exception. The code tries 10 times on KVM node to remove RBD
> snapshot but because there is no snapshot on RBD side it get exception after
> 10 retries, it also spends nearly 5 minutes to delete snapshots and after
> that it ends with an error like "Failed to delete snapshot" error.
> I think we need to disable snapshot cleanup on primary storage only for RBD
> type Primary Storage if its related vm was already been destroyed. (Because
> vm destroy stage removed all snapshots related to vm on primary storage so
> there is no need to take any action on primary storage.)
> We make some tests below to make this issue clear for bug.
> 1) We create a vm with 3 snapshots on ACS.
