I'm shrinking a partion size with 

#Reduce Partition Size fsck -f /dev/sdb2 resize2fs /dev/sdb2 -M -p #Limit Partion fdisk /dev/sdb ... #Now I'm changing the Partition 2 to the new (smaller) size

fdisk gives me a (red) warning like partition#2 contains ext4-signature (Partition #2 enthält eine ext4-Signatur)

Is there something wrong? Why does the fdisk show me a warning?

I tried to found the same. So it means there're EXT4 fs on this partition. For example, on partition and FS increasing this warning appears to. Just select "N" if you don't plan to remove fs.

Created a new partition 1 of type 'Linux' and of size 100 GiB. Partition #1 contains an ext4 signature. Do you want to remove the signature? [Y]es/[N]o: N
