GabrielBrascher opened a new issue #3590: Revert Ceph/RBD Snapshot issue URL: https://github.com/apache/cloudstack/issues/3590 #### DESCRIPTION The following exception shows that the parameter "path" had different data from what it was expected to have. I assume that it got the account id "2" instead of the image id: ``` 2019-09-06 21:27:16,094 ERROR [resource.wrapper.LibvirtRevertSnapshotCommandWrapper](agentRequest-Handler-3:null) (logid:9593f65a) Failed to connect to revert snapshot due to RBD exception: com.ceph.rbd.RbdException: Failed to open image 2 at com.ceph.rbd.Rbd.open(Rbd.java:243) at com.ceph.rbd.Rbd.open(Rbd.java:226) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtRevertSnapshotCommandWrapper.execute(LibvirtRevertSnapshotCommandWrapper.java:92) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtRevertSnapshotCommandWrapper.execute(LibvirtRevertSnapshotCommandWrapper.java:49) at com.cloud.hypervisor.kvm.resource.wrapper.LibvirtRequestWrapper.execute(LibvirtRequestWrapper.java:78) at com.cloud.hypervisor.kvm.resource.LibvirtComputingResource.executeRequest(LibvirtComputingResource.java:1476) at com.cloud.agent.Agent.processRequest(Agent.java:640) at com.cloud.agent.Agent$AgentRequestHandler.doTask(Agent.java:1053) at com.cloud.utils.nio.Task.call(Task.java:83) at com.cloud.utils.nio.Task.call(Task.java:29) at java.util.concurrent.FutureTask.run(FutureTask.java:266) at java.util.concurrent.ThreadPoolExecutor.runWorker(ThreadPoolExecutor.java:1149) at java.util.concurrent.ThreadPoolExecutor$Worker.run(ThreadPoolExecutor.java:624) at java.lang.Thread.run(Thread.java:748) ``` The parameter [snapshotRelPath = snapshot.getPath()](https://github.com/apache/cloudstack/blob/61b8b779137739bb5b890f48c5164085075d0286/plugins/hypervisors/kvm/src/main/java/com/cloud/hypervisor/kvm/resource/wrapper/LibvirtRevertSnapshotCommandWrapper.java#L75) is a critical piece of code that can definitely break the rollback execution flow if its content is not the expected. My tests had pointed for a pattern but the reported issue points to other possibilities that were not the expected. I will be working to reproduce this error. Should be soon proposing a fix that will ensure a stable Ceph rollback/revert execution. The fix will aim **CloudStack 4.13.1.0**. ##### ISSUE TYPE <!-- Pick one below and delete the rest --> * Bug Report
