Hi,
I am working on CloudStack infrastructure service to build our organization
framework.For this purpose, RHEL 6.4, Cloudstack 4.2.1 and KVM are being used.
I have been working around for long to figure out the below mentioned Issue but
unfortunately could not.
Issue: Snapshot gets stuck in the state "Creating" forever(Screenshot attached).
Impact: Couldn't get the snapshot consequently and thus, the instance from the
CloudStack's UI could not be started/Stopped.
Please see below trace from Management Server log which I think is the reason
behind (full log attached).
Unexpected exception while executing
org.apache.cloudstack.api.command.user.vmsnapshot.CreateVMSnapshotCmdcom.cloud.utils.exception.CloudRuntimeException:
com.cloud.agent.api.UnsupportedAnswer cannot be cast to
com.cloud.agent.api.CreateVMSnapshotAnswer
Please see below trace from agent log which was written at the moment I clicked
on Snapshot button in the Cloudstack's UI:
2014-02-25 17:27:09,129 WARN [kvm.resource.LibvirtComputingResource]
(agentRequest-Handler-4:null) Unsupported command
In order to restart the instance again, I manually delete the row from the
table vm_snapshots in mysql database corresponding to this stuck snapshot.
Please suggest me the fix with proper explanation for this issue.
Thanks in advance.
Regards,Rohit
