Description Philipp Hahn univentionstaff 2017-08-07 17:12:11 CEST
I created a snapshot in UVMM and immediately was back in the snapshot overview page, while the snapshot was taken in the background. As I had no visual indicator that the process was still in progress, I tried to create the snapshot again, as it was not yet listed in the overview page.
This 2nd action then blocked and finally terminated with "an error has occurred" message without details.
