Hi,
Thanks for the logs.
What exact version are you using ? (VDSM,engine)
Regarding the upload issue, can you please provide imageio-proxy and imageio-daemon logs ?
Issue in [1] looks with the same symptoms, but we need more info.
Regarding the template issue, it looks like [2].
There were some issues when calculating the estimated size target volume, that should be already fixed.
Please provide the exact versions, so I can check if it includes the fixes.
Thanks,
Fred
