The import seems to work now. What i'm wondering is that it is really slow. I see around 10% CPU Usage on importing host (host where rbd import is started) and just 4MB every 2s raising Data on ceph. This means 40GB took around 5-6 hours. Night this be due to he size update? 4MB every 2s looks like the stripe size. Greets, Stefan
