I wan't to install Longhorn on my K8S Cluster, I added two more Harddrives for Storage, is it enough to add them to Server so that they are available as
/dev/sdX
there is no Partition Layout or Filesystem on them.

No, they need to be formatted with a file system

Longhorn support multi-disk but need format the device as supported file systems, e.g.,
xfs
and
ext4

The Longhorn team doesn't currently make any recommendations for one underlying file system versus another. The performance testing undertaken in this issue (https://github.com/longhorn/longhorn/issues/2986#issuecomment-923404663) doesn't seem to indicate significant performance differences (compare
Longhorn volume with 3 replicas (host filesystem is ext4)
with
Longhorn volume with 3 replicas; xfs host filesystem
).
