[Users] Exports : many success, one failure

[Nicolas Ecarnot]

Hi,

I was NFS-exporting many VMs from a 3.1 (iscsi) to a 3.3 (iscsi) oVirt 
and it was running fine.

On a linux VM with 2 disks, I see the export process smoothly filling up 
the NFS tree. When its seems to reach the data expected size, the web 
gui tells me the export has failed.

The engine.log shows this, which does not help me much.

2013-10-14 16:23:12,603 ERROR [org.ovirt.engine.core.bll.SPMAsyncTask] 
(QuartzScheduler_Worker-82) BaseAsyncTask::LogEndTaskFailure: Task 
f931d5cf-1b73-408a-8149-2c4bada047ec (Parent Command ExportVm, 
Parameters Type 
org.ovirt.engine.core.common.asynctasks.AsyncTaskParameters) ended with 
failure:
-- Result: cleanSuccess

HSMGetAllTasksStatusesVDS, error = low level Image copy failed,
-- Exception: VDSGenericException: VDSErrorException: Failed to

There is still plenty of disk space on the nfs export domain.
Network has not been interrupted or whatever.

There are snapshots but I checked the collapse box when exporting.

What should I look at?
