Subject Intermittent - snapshot problem.
Date Thu, 20 Dec 2012 11:43:26 GMT
Hi,

I'm aware that 4.0 is out however I'm still on 3.0.2 due to with current issues and upgrade
problems on 4.0.
I've encountered a strange issue with snapshots on my 3.0.2 production system.
Snapshots intermittently fail after approx. 3.5hrs later with:

2012-12-20 04:34:10,197 WARN [cloud.vm.VirtualMachineManagerImpl] (AgentManager-Handler-1:null)
Cleanup failed due to BackupSnapshotCommand exception: java.lang.Exception: Unable to finish
the whole process to package as a OVA file
2012-12-20 04:34:10,198 WARN [cloud.vm.VirtualMachineManagerImpl] (Job-Executor-93:job-1522)
Cleanup failed due to BackupSnapshotCommand exception: java.lang.Exception: Unable to finish
the whole process to package as a OVA file
2012-12-20 04:34:10,203 DEBUG [storage.snapshot.SnapshotManagerImpl] (Job-Executor-93:job-1522)
The result for com.cloud.agent.api.BackupSnapshotCommand is BackupSnapshotCommand exception:
java.lang.Exception: Unable to finish the whole process to package as a OVA file
2012-12-20 04:36:10,205 WARN  [storage.snapshot.SnapshotManagerImpl] (Job-Executor-93:job-1522)
Storage unavailable com.cloud.exception.StorageUnavailableException: Resource [StoragePool:200]
is unreachable: Unable to send command to the pool 200 due to there is no enabled hosts up
in this cluster

While VMware reports that the OVA file exported successfully and there are no alerts anywhere
within the system but snapshots are failing, some succeeds some does not.
Are there any timeout settings apart from "backup.snapshot.wait" which is 8hrs at the moment
I should be aware of and would affect this?
Any ideas?

Regards
