For the record, the flag is --storage-opt, not --storage-opts

Actually it is "storage-opts" in the /etc/docker/daemon.json file indeed.

Also remember that the backing filesystem of /var/lib/docker/ needs to be ext4 for overlay2. XFS will not work.

Also remember that the backing filesystem of /var/lib/docker/ needs to be ext4 for overlay2. XFS will not work.

According to the docs, XFS is supported if filesystem ftype is set to 1.
Check with: $ xfs_info | grep ftype
