The bug seems to be like that : when partitioning manually, if you delete the original partitions and create the same partitions (same filesystem , size and mount points), it will alarm and tell you the newly created partitions missing mount points.Due to my bad skills,I didn't catch the log,but this bug is easily reproducible when I do the same way I mentioned above.
