xva backup fails to import

[Mitch Vega]

We are running XenCenter 7 (build 7.0.1.3852 running on WinServer 2008) and trying to import a backed up .xva VM, that fails (we have numerous monthly backups that all fail)

 

To import the xva from XenCenter: File > Import > Browse > select the desired monthly xva > Next > Select the Server pool > Storage > Import > Select network config > Finish....pretty standard import.

 

The process failure time varies but it usually takes awhile...an hour or two maybe. The logs dont reveal anything that is helpful to me, but I am pretty green to the Xen environment. Any input as to what would be causing this failure?

Is there plenty of storage space on the target SR? If you run "xe task-list" from the CLI after starting the process, do you see any progress at all as it keeps trying to perform the task?

looks like 890gb free on the SR

 

As for the xe task-list output....looks like an upload task and VM console connection - both pending. going to read up on what these mean

Pending means the process has not kicked off. I'd try to kill it via xe task-cancel and restart it. Maybe try first with a very small VM as a test?

Pending means "running" and not complete. You can see it's in progress by the 0.419 (i.e. 41.9% complete)
