I have an unused 200GB partition that I'd like to use to copy / export / backup a few VMs onto, so I mounted it to one of my oVirt hosts as /ova-images/, and then ran "chown 36:36" on ova-images.
From the engine, I then tried to export an OVA to that directory.

Watching the directory with "ls", I see a filename.ova.tmp eventually appear, and it grows to the size I would expect for the image... and then a few seconds later, it disappears.

What am I missing?

Here's what I see in the Event Manager inside the Engine:
