This sounds strange on the first sight because it does not show anywhere that one has to double the metadata. Or better: that it is currently doubled. So I know what I have to do now. I will drop the partition and create it again. There is then still the problem that I have twice the size of metadata than real data. But I guess that is due to the high number of very small files (current estimate is 1440*50000 files with around 200Bytes to 2000Bytes). On the other hand there is only twice the size reserved and actually used a bit more that the real data. Many thanks for make that clear to me.
