DaanHoogland opened a new pull request #3969: Snapshot deletion issues URL: https://github.com/apache/cloudstack/pull/3969 ## Description <!--- Describe your changes in detail --> copy of PR #3649 on joint account for easier cooperation. Tested both cases: - Snapshot backed up on Secondary (stored on primary and secondary) - Snapshot stored only on primary storage. This fix works for KVM and XenServer. **Note**: I changed the name of the strategy from _XenserverSnapshotStrategy_ to _DefaultSnapshotStrategy_ due to the fact that the "Xenserver" strategy handles also Ceph, KVM, and do return `StrategyPriority.DEFAULT` in any case except _REVERT_. ``` @Override public StrategyPriority canHandle(Snapshot snapshot, SnapshotOperation op) { if (SnapshotOperation.REVERT.equals(op)) { long volumeId = snapshot.getVolumeId(); VolumeVO volumeVO = volumeDao.findById(volumeId); if (volumeVO != null && ImageFormat.QCOW2.equals(volumeVO.getFormat())) { return StrategyPriority.DEFAULT; } return StrategyPriority.CANT_HANDLE; } return StrategyPriority.DEFAULT; } ``` Fixes: #3646 ## Types of changes <!--- What types of changes does your code introduce?
