The idea is good there was a bug whic= h blocks this idea to work and it was fixed with CLOUDSTACK-9297 bug.=20 > 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 st= orage 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 i= t block our idea to work. If you destroy a vm which is on RBD Storage as pr= imary storage it also deletes any related snapshots of that vm on Primary R= BD Storage. So after vm destroy no disk file or snapshot file over RBD Stor= age. This is good for cleanup purposes on primary storage but XenserverSnap= shotStrategy.deleteSnapshot class method did not expect this to happen. > org.apache.cloudstack.storage.snapshot.XenserverSnapshotStrategy.deleteSn= apshot method receives exception. The code tries 10 times on KVM node to re= move RBD snapshot but because there is no snapshot on RBD side it get excep= tion 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 R= BD type Primary Storage if its related vm was already been destroyed. (Beca= use 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. > mysql> select * from snapshot_store_ref where snapshot_id in (93,94,95);
