------------------------------------------------

             Summary: Deleting Snapshot From Primary Storage Fails on RBD Storage if you already
delete vm's itself
                 Key: CLOUDSTACK-9538
                 URL: https://issues.apache.org/jira/browse/CLOUDSTACK-9538
             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
            Reporter: Özhan Rüzgar Karaman


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.
