The various storage drivers in docker are built on various Linux filesystems, like Overlay and AUFS. Each of these filesystems have their own requirements, and in particular, they depend on a specific backing filesystem on the host. For overlay2, that backing filesystem must be ext4 or xfs (with ftype=1). To see more on the various storage drivers and their requirements, see Docker's documentation.
