Error partitioning a Fusion Drive

I wanted a clean reinstall of macOS Sierra and went to the Disk Utility while booting my iMac (Late 2012, i5, 1 TB Fusion Drive). From the DU I removed a partition I no longer need and the whole thing crashed (beach ball for 3 hours). I pressed the power button on the back and restarted. Now that I have macOS installed I wanted to create a new smaller partition. But I get always this error message:

The request would shrink one of your Core Storage physical volumes to a size of zero. Try a more modest change in size.

It doesn't matter if I use DU on macOS directly or with CMD + R.

I don't know that to do and how to get rid of that error. Any idea?
